v1.38

release notes software v1 38 overview welcome to printer software v1 38 important note this software update includes some behind the scenes maintenance to core systems on the printer this maintenance is critical to the long term stability of the system these changes do not impact how your printer prints, and will not alter how you interact with your printer however, due to the foundational nature and breadth of this maintenance, installing this software update will take longer than usual please allow 45 minutes to install this software update from v1 37 the printer will be unavailable until the software update is complete do not restart/power cycle your printer during the software update additionally, if you are currently on an older version of software (eg, v1 36), you will need to update to v1 37 before updating to v1 38 printer software v1 38 will not be released to your printer until v1 37 has been installed in this release, we’ve included the following improvements to your print process changes in how we print improved print quality for keystone keydenture try in with thinner slices print preparation improvements more accurate print time estimates for l1 printers improved zoom behavior options in the print preparation ui gen2 auto layout (beta) for higher density packing denture auto nest improved error handling and flexible user preferences “print date” token for labels show/hide part bounding box additional improvements improved stability and performance for the m3 printer miscellaneous bugfixes we look forward to hearing from you about this release if you have any questions, please contact the carbon support team at support\@carbon3d com mailto\ support\@carbon3d com version details v1 38 0 1342 75 released to select printers on or after 12/12/2022 v1 38 0 1342 82 released to select printers on or after 01/04/2023 v1 38 0 1342 90 released to select printers on or after 01/23/2023 v1 38 0 1342 92 released to select printers on or after 02/03/2023 v1 38 0 1342 99 released to select printers on or after 03/07/2023 version support note carbon requires that customers update software regularly with the exception of specified version lock able older version(s), carbon does not support non current software versions if you require support but are running an unsupported software version, note that the first troubleshooting step is to update software to a supported version the following are supported printer software versions as of the publication of these release notes (december 2022/january 2023) v1 38 (current version) v1 37 (supported until march 2023) v1 31 (version lock offering; supported until fall 2023; you must contact carbon if you wish your printer to be version locked) changes in how we print improved print quality for keystone keydenture try in with thinner slices print settings for keystone keydenture try in have been adjusted to support printing at 50 um (“fine”) and 25 um (“super fine”) slice thicknesses print behavior for the previously validated 100 um slice thickness (“standard”) has not been altered if you have previously attempted to print with this resin at 50 um or 25 um slices and experienced print defects, you may wish to try again after updating to printer software v1 38 print preparation improvements more accurate print time estimates for l1 printers carbon’s l1 printer now offers more accurate print time estimates to help you plan your workflows more effectively the l1 printer uses force feedback to take into account real time print forces while printing while this functionality is designed to enhance print outcomes, it can also make it challenging to predict when a print will complete (as printer movements are not calculated in advance, but rather respond to real time force measurements) carbon has implemented a machine learning model to improve our ability to predict print times while maintaining the flexibility of printing with force feedback via this model, the average print time error on l1 printers is meaningfully reduced overall, this improved accuracy will help you estimate the cost of parts and plan production processes more effectively note that the above information applies to print time estimates for print plans that use force feedback if you are using a print script or print plan that defines another printing method, your print time estimate will not change with this software update similar improvements to print time estimates for the m3 and m3 max printers will follow in a future release improved zoom behavior in the print preparation ui users can now zoom and pan in one motion with the “zoom toward cursor” setting traditionally, zooming in carbon’s print prep ui has zoomed toward the center of the screen to zoom in to a particular area of a build, a user has needed to zoom and then pan to see the desired area “zoom toward cursor” moves the zoom action in the direction of the user’s cursor, integrating zooming and panning into one view control action image the animation below shows the difference between the two zoom behaviors this new zoom behavior is optional to use “zoom toward cursor,” select it as a user preference from your printer dashboard if you do not alter this user preference, the traditional “zoom to center” functionality will continue gen2 auto layout (beta) offers higher density packing a new “gen2” auto layout option can provide higher density packing results, and may be particularly useful for dental labs seeking maximum efficiency from their prints in many cases, gen2 auto layout is effective at packing more parts on a build platform than is achieved by carbon’s existing gen1 auto layout tool it has been designed and optimized for customers with a high mix of one off model designs and for whom maximizing the number of parts per build platform is very important gen2 auto layout aims to out perform experienced human users by matching build density in less time and with less effort note that not all part sets will see increased packing density results depend on part geometry gen2 auto layout is available as an option in the auto layout control panel select “gen2,” choose the amount of padding you want between parts, and click “auto layout ” gen2 auto layout is available as a beta feature in software v1 38 this designation indicates that carbon may identify further improvements that are necessary to optimize the tool if you encounter unexpected packing results, please reach out to support\@carbon3d com mailto\ support\@carbon3d com to ensure we are aware of the issue gen1 auto layout uses carbon’s existing/previous layout algorithm, which has not been altered if you wish to continue using auto layout as it has existed in previous software versions, please use gen1 auto layout denture auto nest improvements improved error handling error handling for the denture auto nesting tool has been improved and streamlined for a smoother user experience and greater nesting success carbon’s denture auto nesting tool relies on an algorithm that identifies the main geometric characteristics of a denture base those identified characteristics are then used to orient and support each model in some cases, one or more uploaded models may not meet the algorithm’s specifications (eg, it may be larger or smaller than expected; tooth sockets may be less clearly defined…) previously, having just one such model included in a build would cause the entire auto nesting operation to fail with printer software v1 38, only the problematic model(s) will be excluded from nesting; others will continue to be oriented, supported, and packed this creates a more user friendly workflow, as the user can quickly see which model failed and proceed to manually prepare that model as needed left on previous software versions, a single problematic model has caused auto nesting to fail for the entire build right on software v1 38, all models that passed the algorithmic check are oriented, supported, and (where possible) packed the operator can clearly see and address the single problematic model if auto nest failures have been a hindrance to your use of this functionality in the past, we encourage you to try it again carbon’s denture auto nesting tool can help make your lab’s denture preparation workflows faster and lower effort if you do not have access to denture auto nesting but would like to try it, reach out to support\@carbon3d com mailto\ support\@carbon3d com for assistance new default behavior and flexible user preferences when the feature is enabled for a printer, denture auto nesting has historically been set as the default behavior for that printer when creating a new project while this has worked well for some customers who use a particular machine primarily to print dentures, it has posed a challenge for others who use a single machine for a mix of applications with printer software v1 38, denture auto nesting will default to “off” when creating a project to enable auto nesting for a particular build, simply toggle the option when uploading files should you wish to have auto nesting default to “on” for each new build, a new user preference is now available this can be configured on a per user basis to reflect individual work patterns and needs “print date” token for labels “print date” is now available via the part labeling tool date based labels can be added in the labeling ui by using the new {date} token the date that appears on the label will match the date when the user presses “print” (which may be different than the date when the project is prepared and the label token is initially applied) a project that is printed multiple times on different dates will thus show the correct print date on each print, without changing the label within the project (note that using the “reprint” functionality will result in a date that does not update, as the project is no longer dynamic in this situation ) the {date} token supports a wide variety of date formats by altering token details for example, {date\ dd mm yyyy}, {date\ mm yy}, {date\ mm dd yy}, and so on time can also be included for a full list of possible date formats, refer to format documentation for day js xxx the time zone will default to the browser time zone in which the project was created if needed, you can select a different time zone from the available drop down menu did you know? if you use the same label settings regularly (the same token; the same engraving/embossing depth; the same font size), you can set these as your default via the user preferences section of the printer dashboard to save time when preparing similar prints show/hide part bounding boxes bounding boxes for individual parts can now be toggled on or off when viewing a project in the print preparation ui you may find this useful if bounding boxes are a distraction when placing supports or viewing details of a project – particularly if your project contains small parts to turn bounding boxes on or off, look for a new control in the bottom bar of the ui or use the keyboard shortcut shift+b below a new “toggle bounding boxes” icon is available in the bottom control bar to hide/show bounding boxes xxx file size too large for here additional improvements while the features described above are the most noticeable and impactful changes in this software release, there are a few more minor changes you might want to be aware of increased stability and improved performance for the m3 printer through improvements to the oxygen control system m3 printer is quieter at idle via reduced fan noise software support for the new m3 max printer prints queued from cloud applications (eg, automatically generated builds, or projects stored in the build catalog) are now displayed on printer queues with their source as “cloud” rather than “bastion tunnel” miscellaneous bugfixes the following issues have been resolved with this release print prep ui will no longer show “ghost” reminders of unvented volumes that previously existed, but are no longer relevant due to changes to part orientation gen2 slicer can more capably handle parts with carbon generated supports resolved an issue that blocked the deletion of supports in certain circumstances resolved a mismatch between ergo height settings and post print platform heights for taller prints to avoid inadvertently blocking a platform from removal (rare) “invalid z offset mm” error message will no longer occur for certain edits made after support generation (rare) update for v1 38 0 1342 82 addresses several minor bugs update for v1 38 0 1342 90 resolves several issues eliminated a (rare) potential cause of unnecessary print aborts on m3 printers reprint functionality is restored for older files (>1 year old) print uuids are strictly limited to 8 digits update for v1 38 0 1342 92 resolved an issue that errantly disallowed non integer values as inputs in advanced print controls update for v1 38 0 1342 99 addressed the following issues reverted changes to how the printer reconnects to the local network after installing a software update to minimize connection issues enabled a more reliable method for printers to communicate with cloud services feedback we love hearing from you about your workflow, your parts, and how we can improve you can reach out to the carbon support team at support\@carbon3d com mailto\ support\@carbon3d com
