I'm not understanding bed coordinates.
I built a printer using RAMPS 1.4, Arduino 2560. IR sensor Firmware: Marlin RC-6. I'm having a problem understand the coordinates. Using Repeiter Host, if I home the X and Y axis, the hot end moves to...

You don't have your X_MIN_POS shown (or your Y_MIN_POS). But assuming they are 0.0 Your Z-Probe is off the bed when you try to home at (X,Y) = (0.0, 0.0) The nearest that I can do a Z home is X=30,...

Thank you Roxy You are correct. #define X_MIN_POS 0 #define Y_MIN_POS 0 #define Z_MIN_POS 0 #define X_MAX_POS 170 #define Y_MAX_POS 260 #define Z_MAX_POS 200 Should it be : #define X_MIN_POS 30...

Should it be : #define X_MIN_POS 30 #define Y_MIN_POS 8 #define Z_MIN_POS 0 No... Leave X_MIN_POS at 0 and the same for Y_MIN_POS. What you want to do is setup things so it does the Z-Probe to home at...

Well it's similar but not equal. #if ENABLED(Z_SAFE_HOMING) #define Z_SAFE_HOMING_X_POINT ((X_MIN_POS + X_MAX_POS) / 2) // X point for Z homing when homing all axis (G28). #define...

Thank you Roxy for your help. I relocated the probe to the right side of the nozzle. Entered the new values and now the printer operates the way I was expecting in the first place. I ran a G29 command...

No... Those 1.00000's are OK. Your correction matrix looks very good. It looks like your bed is very level. (In reality... Those 1.0000's should really be more like .9999 because you have a small X...

I would just move the wire to where it should be. If you know where the code expects things to be, it is easier to get good support if you just conform to what it expects.
