Hi Guys- I need some advice! I am a chemist who has built a CNC running on MACH 3. I use the XYZ to position two discharge tubes into little 16mm vials (250 in a sleeve). Using the “A” and “B” functions, I use two pumps I built using stepper motors, and pump reagents into each vial.
I am redesigning this using MPCNC as a base and Marlin 2.0 on an SKS 1.3, but a bit different gantry. I only need a singe channel for XYZ but need to control the “A” and “B” channels - could be defined as “E0” and "E1- doesn’t matter, but I need to be able to control them using gcode. I can see how to reassign the pins, but can anyone suggest an elegant way to control the E0 and E1? The use o fthe little touchscreen is AWESOME and so much simpler than a full computer- lab space is limited!
THANKS in advance.
