Homing Problem

Post by pwwhdr70 » Thu May 16, 2019 6:41 am

I recently installed my 3DTouch and it seems to work well. All the self tests work perfectly.

However, when I press home on Repetier, it goes like this:

X-axis - OK
Y-axis - OK
Z-axis - flies past center, straight to back-right of bed and grinds the belt

The image shows about where it starts grinding.

I looked in Marlin and can't find any offsets that are different than the setup instructions. Should I be looking for something else?

No, I've been looking online for a solution. Everything leads me to solutions to the nozzle height problem, or something else. I've found nothing related to my specific issue.

I found the problem.

For some reason, my EEPROM settings had the Homing Offset WAYYYY off. I corrected for that and now the nozzle is perfectly centered.

BUT...

Now I can't calibrate my Z-axis. Every time I enter Gcode G1 Z0 it pushes the nozzle into the glass. And the Z offset on the LCD display is still the old one from before I swapped out hotends. I can't change it even though EEPROM is enabled.

At least I made some progress today. Going to sleep on it. Maybe something will come to me tomorrow.
