Hello all,
We are pleased to announce our latest updated firmware for the MK4 with input shaping. Please note that this is still ALPHA firmware. We are able to continue to improve and release updates to the firmware with the help of the community, so please remember that if you run into problems, please report the issue via the github ticketing system as that goes directly to the developers.
Summary
- Power Panic fixed
- Networking fixed
- Layer skipping resolved
- Improvements to prevent layer shifts
- Bootloop fixed
- Minor fixes
Firmware release 5.0.0-alpha3 for the Original Prusa MK4 is focused on bug fixes and improvements.
Power Panic fixed
As noted in the previous releases, the Power Panic feature wasn't working correctly in all scenarios. For this release, most of the issues of implementing this feature alongside Input Shaper have been eliminated. However, further testing and debugging of edge cases are planned to ensure high reliability.
Networking fixed
Similar to Power Panic, the networking features also needed to be fixed. Both Prusa Link and Prusa Connect can be now safely used even with Input Shaper active. Developers are working on further improving the overall performance.
Layer skipping resolved
In the previous releases, the testers have observed an occasional layer skipping. Based on the internal investigation this issue was caused by Pressure Advance (PA). This release, therefore, introduces adjustments to the PA, which also fixes all remaining issues of PA during filament manipulations.
Improvements to prevent layer shifts
Recent adjustments to the stepper queue helped us to bring down the number of layer shifts significantly.
Boot loop fixed
Some users experienced boot loops, which were identified as bus-related. This release includes a fix.
Minor fixes
- Flickering of the footer during the Selftest is fixed.
- Red screens are now signaled with a distinct sound alarm.
- The movement of the axes if triggered from the printer's menu is now smoother.
