Adding 3dtouch to A20M

by LiquidAvGear

Hello All,

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.

Bowden tube not staying

by Chulin5

When i place the ptfe tube into the extruder it spits it out. I've had this printer for a year. The tube is great cause it works on the other extruder. Here I attached a video to further explain this would greatly appreciate some help.

Cura not printing with second extruder

by Devine

Ok so whats happening.

I slice my file in Cura,

right click and select what part for which extruder, than merge the files.
Prime tower is enabled and in correct position
I check layer view and it only shows as extruder 1 printing everything.
sure enough this is what happens when I try a print, Entire print is done on extruder 1.

both extruders work because test prints that cam on sd card worked fine

What am I missing here ? any help would be appreciated

Thanks
