1. An issue with the Product Prompts UI was reported wherein hitting the Enter key multiple times within the interface would result in an unending loop of errors occurring in succession, requiring one to restart the software to fix. This issue has been resolved and should no longer occur for users

Template Fix

1. There was an issue reported by users utilizing the Microvellum 2D template. Namely, during processing, users would experience an error when attempting to nest on Toolbox AC Standard in more recent builds, stating that there was a duplicate record name in the software. This issue did not occur while using Microvellum BSB. This issue has been resolved- a coding adjustment has been applied to Microvellum AC to prevent this issue from happening. 

Perfect Graining Fix

1. Users reported there was a problem with specific saws, wherein operations with perfect graining using specific saws as one’s output would generate G-code with no perfect graining information. This issue has been resolved, and perfect graining information should now appear correctly. 
2. Another issue with perfect graining was reported, wherein some users who selected “Combine CSV XLS” as their conversion type would experience an object reference error during processing. This issue has been resolved, and this error should no longer occur. 

Error Warning Fix

 

1. When experiencing a processing error during an operation, a pop-up warning alerting users to the error should appear, with a “Do Not Show Again” checkbox within it that allows users to prevent warnings from appearing again. Some users reported that this was not the case, with the various error warnings not having the checkbox present, leading to issues of warning pop-ups appearing repeatedly. This issue has been resolved. The "Do Not Show Again" box should appear whenever appropriate in pop-up warnings. 

Vertical Drill Hole Improvement

1. Users reported an issue with slow nesting speed due to the optimizer processing vertical drill holes less efficiently. To address this, compounding on the improvements made in Microvellum release 25.2.0317.641, further improvements have been made to the optimization results of the vertical drill hole optimizer. This may result in more precise and efficiently drilled hole groupings, though results will still vary depending on the tool configuration of one’s specific machine.

Toolfile Fixes

Multiple fixes were applied to issues reportedly occurring during processing that were specifically related Toolfiles and Processing Stations. The following issues have been resolved:

1. An issue was reported wherein barcodes would erroneously be optimized with incorrect barcode numbers. Products with specific barcodes to indicate grouping would sometimes have characters (most often the prefix or first number of the code) drop from the number, leading to incorrect barcode data. 
2. There was reportedly an issue occurring for some users wherein work order processing would be interrupted by an error with the product or part geometry, resulting in the batch being unable to complete. 
3. There was a reported issue by users who attempted to process new G-code created from the composite of a completed work order, wherein elements of the data such as label position would inexplicably change in the data, leading to the operation stalling. 
4. An issue with tool compensation was reportedly occurring wherein the tool compensation of specific tools would sometimes be applied to the incorrect side of a part. 
5. Some users experienced an issue wherein border route machining would sometimes disappear. Namely, after modifying a work order and altering the position Face 6 machining, Face 5 border routing would be removed from the subsequent batch. 
6. An issue was noted with the image output of sawing tools within the Processing Station. When setting the image file paths of a sawing tool, it is expected that the file path settings will be preserved and occur regardless of whether the saw tool is used in a saw processing station or another type. However, it was noticed by some users that the image file would not be generated at the expected location when using a processing station other than the saw processing station. 
7. An issue was occurring during drilling operations, wherein some users would receive an error during processing stating that no drills are available within the software that can reach machined holes. 
8. Another issue with processing routes was reported, wherein parts with routes that were given an offset value would cause a collective error. 
9. An issue would sometimes occur wherein routes and routed holes processed in a batch with IRIB enabled would have erroneous tool compensation, resulting in incorrectly placed routes or holes. 

Optimizer Fixes

Multiple fixes were applied to issues reportedly occurring during processing that were specifically centered around the Microvellum optimizer. The following issues have been resolved: 

1. An issue was sometimes occurring during processing, wherein users would get an error message informing them that a material with perfect graining enabled was not found in the work order and therefore couldn’t be added to the perfect grain container. 
2. There was a reported issue with block nesting. Namely, when attempting to optimize using block nesting with the Max Qty Per Sheet setting at its minimum value (1), some users found they received multiple errors that interrupted optimization. 

 

1. A similar issue would occur for users attempting to process operations using Metric configuration, wherein an error would repeatedly appear stating that there were no suitable parts in the order. Both issues were resolved using the same fix. 
2. An error would sometimes occur when processing work orders using the Multi-Run Optimization option, with an error popping up stating that a specific number of parts were placed correctly without clarification. 
3. There was a reported issue occurring for some users utilizing specific processing stations for nesting their parts, wherein parts would sometimes not be placed correctly within the nest, resulting in an error. 
4. Users reported an issue processing certain parts in sawing operations, with the error claiming the perfect grain container in the operation was too large for any of the material sheets available, regardless of whether appropriate materials were available or not. This would result in the nesting operation being interrupted and unable to complete.

Microvelllum Release Notes | Build 25.2.0317.641

Product Prompts UI Overhaul 

1. Changes can now be saved without closing the UI. Additionally, a checkbox (“Redraw Product”) has been added to allow one to control whether the product should be redrawn when its prompts have been altered and saved. 
2. Prompt tabs now stack vertically rather than horizontally in the interface, eliminating the need to use directional arrows to navigate to the tabs of the interface. 
3. The Product Details section (item number, quantity, angle, comments, etc.) has been relocated to a far more visible location on the lefthand side of the interface.  
4. There is an additional Prompt Help Text box, which retains the Help Text of the last option hovered over in the interface, allowing users to copy and paste descriptions and tool tips.  
5. There is now a setting under Microvellum Settings > Options > General called Product Prompts, which controls the width of Columns 1 and 2. 

Work Order Creation UI Overhaul 

1. Buttons within the interface which open sub-menus (such as Configure Name) have been relocated to the upper right-hand side of the UI to ensure they are grouped in a single location.  
2. The Parts Group and Default Status dropdown menus have been relocated to the center righthand side of the UI for easy and quick access to either option.  
3. A new Comments field has been added to the interface (having been removed from the Properties Interface) to allow for a much faster, easier experience, adding comments to work orders. The comments entered in this field are saved upon work order creation and can be updated if the work order is modified (existing work order comments will appear in this interface as well).
      
4. Additionally, the comment field has been modified to warn users if they exceed the 255-character limit for work order comments, with work orders not being able to process until the character count is reduced, ensuring that no comments are altered or entered incorrectly, as previously, comments would simply cut off after meeting the character limit. 
   
5. The Work Order Name and Select Recent Name fields have been moved to the top left-hand side of the interface.  
6. All checkbox creation options and Microvellum Server checkbox options have been set in the center of the interface, for easy access.  

Use Onion Skin 900 Tools 

1. Previously, when using 900-series tools (multiple tools or multi-pass tools), the software was unable to support the use of the Leave Onion Skin option within Small Part Handling (leaving a thin layer of material from the first cut of a double pass for the second cut to remove). This has changed in this update, with a new checkbox, “Use Onion Skin” being added to Toolfiles when selecting a 900-series tool. This new checkbox will not function unless the “Leave Onion Skin” option in the Small Parts Handling section of the Processing Station is enabled simultaneously. When a 900-series tool is used as the Nest Border Tool and if both checkboxes are enabled, the final pass of a tool will leave the specified onion skin thickness rather than machine to full depth.  

SQL Express 2025 

1. Users working on a server configuration reported issues with errors occurring when attempting to run their software. Specifically, SQL Server Express 2025 would have an issue with attempting to load configurations, with users who attempted to do so experiencing a null data error. This noticeably only occurred when using the Express edition of SQL Server 2025. This issue has been resolved- utilizing SQL Server Express 2025 should no longer cause any errors within the software.  

Work Order Comments Filter 

1.  When searching through large work order databases, it can sometimes be difficult to navigate or locate specific information due to the presence of many comments within multiple work orders.  To resolve this issue, a new filtering feature has been added to the Work Order Selection interface when modifying an existing work order. This checkbox, “Search Comments”, places a filtering for specific text entered in the Search Bar, allowing users to search for specific words or characters within comments of their work orders, to better locate specific work orders within one’s database.  

Work Order Permissions Modification For Label Only Access 

1. A new setting has been added to the Employee Permissions interface, to allow for better control over which employees can process work orders, load parts, or manage scrap. The “Work Order Processing” permission has been added to the Employee Permissions interface under the Work Order section. If this permission is left disabled, the employee in question will only be able to print labels within the Processing Center.  
2. Additionally, the “Access Production” setting within the Module Access section has been renamed and relocated. This checkbox allows the employee in question to log into and utilize the functions of Microvellum Production and the Processing Center as a whole. The setting has been renamed to “Access Work Order” and moved to the Work Order section of the Employee Permissions interface.  
3. Both changes have been applied to the standalone Processing Center application, as well as Microvellum AC and BSB.  

Block Nesting Improvement 

1. The efficiency of block nesting with Microvellum’s optimizer has been improved. Previously, it was reported that the current optimizer was less effective at calculating material sheet stacks during block nesting optimization than the legacy optimizer. To address this issue, the maximum quantity of sheets per stack has been increased within the coding, and a new slider has been added to the Nest Processing Station’s optimization section: “Sheet Quantity Preference”. This slider functions similarly to the “Stacked Material Preference” slider in the Saw Processing Station but applied to block nesting specifically to allow for general control over whether the optimizer prioritizes yield or quantity of stacked sheets during the operation. This setting may thus result in a significant improvement in the number of stacked sheets when using block nesting. 
   
2. The slider will be greyed out whenever the Max Quantity Per Optimized Sheet text box is set to a value of 1 or less. If a value of 0 or less is entered, the text box will automatically raise it to a minimum value of 1. Previously, if the value was set to 0, it would reset to a default value of 5 when the Processing Station was closed and re-opened. 
   

Saw Delimited Setting Fix 

1. Issues were reported with specific settings disappearing when viewing them in the processing station interface. Users who set their output type to “SawDelimited”, then assigned custom values to the saw and processed the work order found that while their custom values are visible in the XML file and processing, they would not appear in the Saw Processing Station when reopened so it appeared blank, leading to confusion. This issue has been resolved - custom values assigned to saws should appear appropriately within the values column.  

Move Part Warning

1. Yes.  Allows you to move the part 
2. No.  Places the part where it currently is 
3. Cancel.  Returns the part to is original location 

Nest Editing ESC Error 

1. An issue was noted with the nesting tools, wherein moving parts, then canceling the command with the Esc key would cause an error. This issue has been resolved- canceling a command after moving a part should no longer result in an error.  

Label Creation Fix 

1. There was sometimes an error that would occur for users attempting to process work orders, wherein setting the work order to generate labels would sometimes result in the order failing to process successfully, instead causing an exception error. This issue has been resolved- users should no longer experience this error when generating labels as part of processing a work order.  

Optimizer Fixes 

1. New coding has been added to identify parts as FromPerfectGrain. Perfectly grained parts now have a number assigned to identify them to the software. 
2. There was a reported issue with optimizing parts that had perfect graining assigned to them, with parts sometimes failing to align correctly, and perfect graining containers sometimes disappearing from the composite.  
3. When using the current optimizer, there was sometimes an issue with specific parts (such as wall components) being erroneously rotated at random.  
4. Users reported an error occurring when attempting to launch nesting operations with products from more than 1 project as part of the work order.  

1. An issue would sometimes occur with parts in sawing operations. When parts in a sawing operation had perfect graining applied, steps in the process such as trimming would sometimes fail to apply correctly. This would sometimes result in the trim failing to register, while at other times, it would result in other parts being cut into. 
2. An issue would sometimes occur during nesting operations, wherein parts with perfect graining applied would sometimes grain match incorrectly, resulting in incorrectly placed parts or software errors to occur. 
   
3. Users would sometimes experience an error when processing certain parts, with the error stating that “Materials were not supplied”. 
   

 

1. A slight grammatical error between the nesting and sawing processing station, the name of the multi-run optimization setting, has been amended. Previously, the setting was referred to as “repeating optimization” in the sawing processing station, and “Enable Multi-run Optimization” in the nesting processing station.  
2. When optimizing with Trueshape enabled, it was sometimes the case that certain parts would cause the optimizer to fail to place any parts, without any warning or alerts regarding the issue.  
3. All of these issues have been resolved, and should no longer occur for users.  
   

Machining Fixes 

1. Users reported an issue when Destroy Offal is turned on with True Shape set to high it was cutting into other parts. This issue has been resolved- parts should no longer be cut into due to the Destroy Offal setting. This also fixed an issue with Shadowline cutout widths varying.   
   
2. An issue was reported regarding incorrect part machining applied to parts rotated at specific angles. Namely, parts that were machined that were rotated at diagonal angles would sometimes be machined incorrectly, resulting in incorrectly cut parts.  This has been resolved.
   

1. A related issue was reported wherein users would have vectors of their routing machining drop during processing. Notedly, this would only occur when processed with the Machine Cannot Offset Routing (MCOR) setting enabled.  This has been resolved. 
   

1. An Offset Polyline issue was reported wherein extra vectors (and thus, routes) would be incorrectly added to 2D drawings, causing incorrectly shaped parts. This issue has been resolved- a coding fix was applied to enhance the software’s ability to determine whether a route is a pocket. Additionally, the default value of parameter 4 in the PLINE5 machine token has been modified from 3;0;1;0;0 to 3;0;3;0;0.  
   

Processing Center Improvements 

1. The Processing Center standalone application is now capable of being opened without requiring a work order to be loaded within the software. A new “Continue” button has been added to the login UI of the application to allow users to open the application without first loading a work order.  

Improved Vertical Drill Optimization 

1. An improvement has been made to the optimization results of the vertical drill hole optimizer. This may result in optimal hole groupings, though results will still vary depending on the tool configuration of one’s specific machine.

Microvellum Release Notes | Build 25.2.0223.641

Add 2D Elevation Tokens to 3D Drawings

Fig. 1: The new 2D Elevation setting.

1. A popularly requested feature by the community has been added to the Microvellum software: the checkbox Add 2D Elevation Tokens to 3D Drawings is now available under the Drawing Preferences section of the CAD tab. This setting, when enabled, creates a 2D Elevation Drawing automatically when the 3D model of the product is drawn. This setting can be enabled simultaneously with the identical function that adds 2D Plan tokens, provided one’s drawing preferences are set to a 3D setting. 

Fig. 2: The new 2D Elevation Tokens to 3D Drawings option enabled.

Processing Center Application

1. A new Microvellum software application has been released: the Processing Center. The Processing Center application is intended to give users access to the full suite of Microvellum’s existing manufacturing tools to process existing work orders, independent of any existing CAD-based applications. It is intended to provide users with an enhanced experience and act as a replacement on the shop floor for applications like MV Production (or MicroManager). For more details about the Processing Center application, visit the following article. 

Processing Center Ribbon

Fig. 4: The Labels & Reports tab of the embedded Processing Center's ribbon.

1. In conjunction with the release of the standalone processing center application, the processing center within Microvellum AC and BSB has received an update to improve usability. The Processing Center (both in the standalone application and embedded into the software) has had a ribbon added to the top of the UI to grant users a fast, easy means of accessing the most used functions within the system. Users can now select part loading, work order management commands, scrap options, labeling and report options, and more instantly without needing to open a separate menu.
