Summary
- Changes to self-test
- Extended Connect Wizard
- Timeout for G-code M115
- Updated bootloader
- Fixed bugs
This firmware release 5.0.1 is addressing self-test issues that may occur after assembling the printer. If your printer is already calibrated and printing without problems, you can skip this update.
We have recently released several firmware versions for MK4. Here's a quick recap:
- The latest stable firmware release is 5.0.0, which is recommended for all users.
- Today's release, 5.0.1, is a direct successor to 5.0.0 and is also recommended for all users.
- Additionally, we've introduced a development version, 5.1.0-alpha2, which we recommend only for experienced users.
Changes to self-test
While the majority of the MK4 printers assembled at our factory or at home (kit, upgrades) are passing the self-test for all axes, a small portion of the printers was failing. This issue was mostly connected with the X-axis. Based on the feedback and testing, the self-test parameters were adjusted to accommodate these printers.
As part of the self-test changes, we have also implemented an improved algorithm for calibrating homing sensitivity.
Extended Connect Wizard
Once the Wizard for Prusa Connect is initiated, the printer tries to establish a connection with the server. For better clarity the screen is now showing the amount of remaining attempts. If the connection fails, you will be informed citing a specific error. The message on the screen will also provide a link to our knowledge base site, with further troubleshooting instructions.
Timeout for G-code M115
When starting a print, the system checks for new firmware. If an update is available, a message is displayed on the screen, and until now, it prevented the print from continuing. This release addresses this issue by introducing a 30-second timeout, after which the print will resume.
Updated bootloader
As part of this firmware release, we are introducing a new bootloader v2.1.3. This update includes support for the latest hardware revision of the xLCD. While this revision of xLCD offers the same features as the current version, it incorporates components from new vendors. Therefore, updating the bootloader is necessary to ensure proper recognition of this xLCD revision.
Fixed bugs
- Red screen with “Heap Malloc Error” is now fixed.
