supported until march 2024) v1 39 (supported until 2026 if your printer is enrolled in version lock ) any feature marked as “beta” in the user interface and/or these release notes is considered by carbon to be an early access technology early access technologies may not be at the level of performance typical of a final product or feature offering, and such features may be altered or withdrawn by carbon at any time and without warning changes in how we print epu prints on an l1 printer with a b1 cassette use updated default print settings in printer software v1 36 (july 2022), carbon introduced the l1b1 epu default print profile to offer improved printability and faster print times for epu parts printed on this hardware combination this print profile was further refined in subsequent software releases because of the general success of this print plan, this printing behavior is now default for all epu prints on l1 printers with b1 cassettes this means that all l1 epu prints on b1 cassettes will now automatically have these print plan settings applied without needing to select a specific print profile dropdown important notes if the correct cassette type is installed in the printer, it is not necessary to select the cassette type (b1 l1) for the proper settings to be applied; the cassette type will be detected automatically default print settings for l1 epu prints on c2 cassettes are unchanged the l1 b1 epu default print profile is still available via the print profile drop down menu for this release, but will be removed in a future version if you have projects that currently use the l1 b1 epu default print plan, please change the print profile to “default” after updating to v1 41 to avoid future disruption when the print profile is retired if this change poses challenges for any l1 b1 epu projects that rely on older default print functionality and cannot easily transition to this new default, reach out to support\@carbon3d com for assistance improved accuracy for dreve fotodent® gingiva, sil 30, mpu 100, and henkel loctite® 3d ind 405 clear resins dreve fotodent® gingiva print settings for dreve fotodent® gingiva have been adjusted to address customer feedback that gingiva print results were smaller than intended when compared with the original model stl fotodent® gingiva will now print slightly larger to achieve better mating surfaces sil 30 print settings have been updated for sil 30 this includes raising the temperature to which resin is heated for printing from 30°c to 40°c these changes should improve the overall accuracy of printed parts compared to the model stl and make green state parts easier to handle mpu 100 and henkel loctite® 3d ind 405 clear print settings for mpu 100 and henkel loctite® 3d ind 405 have been adjusted to improve the accuracy and consistency of parts printed across different printers print preparation improvements improvements to gen2 auto layout (beta) packing density gen2 auto layout can now achieve better packing density in most cases, gen2 auto layout will be more effective than gen1 in successfully placing as many models as possible on the print platform limit part rotations by default, gen2 auto layout tries four rotations of all parts (based on each model’s starting orientation) if you do not want gen2 auto layout to rotate parts, you can now disallow rotation, or allow only a single 180° rotation this behavior may be desired if you have oriented parts specifically for cleanability bugfix in addition to the above mentioned changes to gen2 auto layout, we resolved an issue that could cause parts to overlap in some situations more accurate print time estimates for l1, m3, and m3 max printers to improve customers’ ability to accurately estimate the cost of projects and effectively plan production schedules, time estimates for l1, m3, and m3 max printers have been improved while print time estimates for these machines can never be perfect due to the impact of using force feedback technology to adjust the print plan in real time in response to in situ print forces, quoted estimates are now more accurate this update accounts for general print time improvements for both rigid and elastomeric resins enabled in recent software releases printer ecosystem improvements more navigable prints and projects lists open in new tab on the projects and prints lists (printername customer print carbon3d com/projects and /prints), you can now hold down cmd/ctrl (mac/windows) while clicking the left mouse button to open the project or print in a new browser tab example opening a project or print in a new tab new sorting options on the projects list (printername customer print carbon3d com/projects), you can now sort projects by number of prints (ascending or descending) or alphabetically by project name (ascending or descending) this is in addition to existing sort options of modified/created date example sorting the projects list improved software update experience to discourage users from turning off or restarting printers while a software update is running (which can cause a server failure that requires a service visit to remedy), additional onscreen messaging has been added to the printer screen while the update is installing depending on which specific previous software version a printer has installed when accepting the update to v1 41, users may or may not encounter this new behavior while installing v1 41 (all printers will display this behavior in the future, when updating from 1 41 to 1 42, as well as for future updates thereafter ) example printer screen instructs users not to power off or restart the printer while the update is installing; multiple different screens will appear during an update 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 full project details are now available from the project analysis tab and the print record (rather than only in print plan adjustments, which is an optional feature); click “view details” to access this information project details now include the cassette type additional guidance is provided when a user is downloading parts with supports and/or labels to avoid confusion about how these features are handled in downloaded stls when existing supports are selected in the print preparation ui, parameters are grayed out/inactive to clarify that generated supports cannot be altered to modify support parameters, delete existing supports and re generate improvements to print plan adjustments (optional feature; contact support\@carbon3d com for access) users can run project analysis for projects they do not own selected graphs can be easily cleared in bulk additional slice level parameters introduced in v1 40 are now available to all enabled customers graphing options extended to include parameters introduced in 1 40 detailed project information on the print plan page is more clearly labeled as “view details;” this dialog now includes additional information related to new parameters introduced in v1 40 upon request, the “cancel” button on the l1/m1/m2 printer screen can be hidden to avoid operators erroneously deleting prints from the queue; contact support\@carbon3d com to request this functionality improved error messaging when a project cannot be accessed for printing to help users self serve a solution improved guidance to the user when a printer is recovering from a power failure miscellaneous bugfixes the following issues have been resolved with this release improved the performance of support generation on models and patches with sub optimal triangle meshes adjusted print preparation ui caching behavior to avoid unexpected results when using the browser’s back/forward buttons m3 printers are no longer susceptible to frequent alerts due to air flow leaks note some printers received a patch for this bug in 1 40 due to high need resolved a rare bug that could cause a print plan to be overwritten with another project if prints were analyzed/sliced at the same time (within 500 milliseconds) note some printers received a patch for this bug in 1 40 due to high need when the enter key is pressed to queue a print, only one print will be queued even if the key is held down for an extended period of time updates update for v1 41 0 1504 75 includes minor bugfixes related to uncommon workflows update for v1 41 0 1504 78 enables printing with a new l1 cassette type; this cassette type is not released at this time, but note that this software version (or higher) will be required for customers receiving the new cassette type update for v1 41 0 1504 80 extends support of this software version to printers with older servers ensures that printing workflows used by aligner manufacturers are compatible with a new l1 cassette type (not yet released as of the publication of these release notes) update for v1 41 0 1504 83 resolves a bug that can cause the printer to intermittently display a “socket hung up” error; experience slow loading times; and/or display unnecessary errors resolves a force sensor issue seen on some m3 max printers (rare) this version can be deployed to printers experiencing the above mentioned issues on an as needed basis version lock while carbon encourages customers to stay current with software updates to access the latest features and printing improvements, we recognize that some production applications have stringent validation rules, and may be better served by a stable software version for this reason, carbon offers a version lock program that allows customers to stay on a single, specified version of software for up to three years, with full support v1 39 is available for version lock if you are interested in placing your printer(s) on version lock, contact support\@carbon3d com 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
