I was tooling around in the Marlin firmware last night and I found the area of homing the axis. I was thinking I can just comment out the line of code to home the Z. Do you guys know if that is possible? I am waiting on some endstops to get here so I can try this out.
// ENDSTOP SETTINGS:
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
//#define Z_HOME_DIR -1 (Comment out this line only)
I am not too concerned with tool changes right now. I would like to be able to home the axis and then manually move the spindle using the LCD controller to location that is set by a couple of dowel pins. I am planing to have grid of dowel pin locations on the table every 100 or so mm so i can use these as 0,0 depending on the size of the work piece.
Let me know what you guys think or if there is a much more simple way to do this. The only reason I am thinking of doing dowel pins is because this is how we do it on the CNC machines we have at work.
