So I have been going through modding my printer and I have come across a new problem that I have not had issues with before.
My 3D printer will start to print above the heating bed even though it gets properly homed all the endstops. At first it was off by half of the whole Z-axis distance using Cura and off by 0.5 mm on MatterControl. Since playing around with random settings in both programs, my printer now seems to only be off by 0.25 mm from the heating bed. None of the settings appear to be affecting anything.
My guess is something both programs remembered was off and now it's been corrected to a degree?
Homed at endstops:
Homed to a papers width above the heating bed:
Here the printer has started to print and it off by 0.25 mm:
