Having a bit of a brain moment and need to ask a question
have a machine with 100% custom firmware, Marlin 2.X firmware. Do not have access to the source code.
Printer homes X and Y ok, when it homes the BLtouch is off the edge of the bed, consequently, the probe extends properly but never touches the bed to properly home the Z-axis.
I was thinking about updating the M851 with the proper offsets but I think Im going to end up losing X and Y printable area because of it.
Can someone confirm that my thinking is correct or am I committed at this point to repunch the firmware from scratch and enable safe homing on it?
