I have tried and failed for the past week to add a 3d touch to my A20M - GT2560 V3.X running Marlin 1.1.8. I followed all the steps but seem to hit a stop during the auto home where the printer tries to drive the Z through the bed.
I tried the Gethub and Arduino step but it had errors I couldn't correct during the verify section
Attempted the file load from Geeetech but it says it all gtg but same error occurs.
Has anyone seen this before or have a way I can at least get my printer back to how it was so I can still print.
