1.5.3

New Features:

• None. This is just a bugfix release

Bugfixes:

• Fix build issues when compiling with newer Python versions
• Fix Thermal Runaway, which was too aggressive in some cases
• Fix Filament Runout, which which resulted in false positives in the past
• Fix manual bed leveling on Mega Pro

Known Issues:

• The built-in leveling of the 4MAX Pro does not work yet. Use the 4-point-easy leveling and mesh leveling via the special menu instead.
• The Mega Pro BMP Laser feature is not (yet) supported. Use the M3 Spindle/Laser feature instead.
• The Nozzle temperature can only be set over 260°C via gcode and not the Touchscreen. This issue can not be fixed.
• The gcode filetransfer via Wifi is pretty slow due to to hardware limitations.

How to Install:

1. Follow the Beginner's Guide which is also available in german as "Einsteiger Leitfaden".
2. Read the FAQ which can also be found in the Wiki.
3. If you own a MEGA S or MEGA PRO, set your Bed size in your Slicer to these values.
4. Use Cura, PrusaSlicer or xLoader to flash the Firmware to your Printer.

Important: Be sure to select "LOAD FW DEFAULTS" and "SAVE EEPROM" via Special Menu after updating! *

*You may not have to reset everything.
However, the prerequisites for this are difficult to tell, which is why I wrote something this topic here in english and here in german.
