This is the newest version of the Marlin Firmware, customized and optimized for the 4Max Pro based on davidramiro, derhopp and alfrank changes.
Anycubic's touchscreen implementation is very hacked together and is based on the old Marlin beta version 1.1.0-RC8. In addition, the wrong thermistor for the hotend is entered in the stock firmware, which has been fixed in this version. Also if your hotbed is concave or not straight you can use the mesh bed leveling.
Warning: If your 4Max Pro works satisfactorily for you there is no reason to do a firmware update. Remember: There is always a way back to the original firmware Anycubic 1.1.7 (Marlin 1.1.0-RC8).
If you don't want to change the firmware yourself, download the latest .hex
file from the releases.

M900
command OR0
to disable Linear Advance). Can be found in Material tab.As soon as the filament is empty when printing, a message appears on the display and the printer removes the remaining filament. Please insert a new one and press "Continue". (Sometimes the command is not transmitted correctly, then first press "Pause" and then "Continue") Now the new filament is drawn in and printing continues.
If you press "Pause" while printing, it stops and your print head moves to the waiting position. If you want to continue printing, press "Continue". Now the printhead is heated up and then moves back into position.
Due to the concave print bed on the Anycubic, you can use the mesh leveling to fix the unevenness. Insert an SD card first and then go to the "Extra Menu" in the print menu. Select "start mesh leveling" there. The print head now moves to the first position. Place a sheet of paper under the nozzle and select "z up" or "z down" on the next page until you notice a slight rubbing on the paper. Now press "next mesh point" and repeat the process. As soon as you have reached the last point, the print head returns to the home position and you can save the new values by clicking on "save eeprom". Don't forget to integrate the mesh leveling into your gcode start script.
