1.3.1

Features:

• Same new Features like in Version 1.3.0 but with disabled Wifi functionality. It can be easily enabled by uncommenting #define SERIAL_PORT_2 in Configuration.h file.

Bugfixes:

• Some users reported USB communication issues when using Octoprint in combination with a USB Webcam. By disabling the Wifi functionality, this issue could be fixed so far.

Known Issues:

• The Mega Pro Laser is currently nor supported at all.
• When setting the Z offset manually, the Nozzle does not move to give you "live feedback". The Offset is only applied after X/Y movement.
• The Nozzle temperature can only be set over 260°C via gcode and not the Touchscreen. This issue can not be fixed.
• On Mega X with original DWIN/DGUS II Display, the pause/resume/filament change feature does not work due to a bug in the TFT Firmware itself.
• The gcode filetransfer via Wifi is pretty slow due to to hardware limitations.
• In some cases, Octoprint loses the USB connection. If this happens, just disable the internal Wifi feature.

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!
