Hello,
I am having problems to get my DIY Printer Running. It only uses the Bltouch and no gamma endstops.
The delta grid probing works fine. But I simply dont know how to home the Z axis. Usually it should Probe the middle of the bed and set this point to Z0 and then start probing the rest of the bed or am I wrong? It always thinks that Z0 is the Position Z was in when I powerd the printer up. After that I can write my Z offset or not?
Here is the starting Gcode:
G28 X Y ; Home X and Y
G1 X0 Y0 F6000 ; Go to center of bed
M280 S3.0 ; Deploy BLT probe pin
G31 ; Probe the bed and turn on compensation
G1 X0 Y0 F6000 ; Go to center of bed
G30 Z1.04 ; Z Probe Offset
M280 S7.0 ; Retract probe pin
