I’m having a problem with my Ender 3 Pro
I’m having a problem with my Ender 3 Pro. Running Marlin 126.96.36.199 on a 4.2.7 mother board. I have leveled the bed with the CR Touch, stored the settings. Then I auto homed the nozzle and stored that setting just to be sure. Then I got a piece of paper, lowered the Z axis so that the paper would just hesitate a little, but the dial would only get to +00.00 and no farther. It won’t give negative settings. The paper isn’t touching the nozzle and won’t go down any farther. Therefore I’m not able to calibrate the Z offset. Obviously I can’t print anything with the nozzle too high off the bed. What do I do ??? I hope I have included enough information. Any help would be appreciated.
