Geeetech Prusa i3 Pro B with GT2560 Rev A+ Current f/w: Marlin 1.0.05
Problem: want to up'ld new f/w to add 3DTouch Sensor capability but latest Arduino version wont connect to the GT2560 although the relevant USB port is listed. Older version of Arduino 1.0.6 ( can't get 1.0.1) is not compatible with Catalina.
What do I do?
