Move Function Issues

Hi
If I set ‘G10 L2 P1 X-1000 Y-1000’ I get negative coords in the move dialog.
using G10 L2 P1 X0 Y0, I get positive coords.
My moves are as expected with the cnc checked. without it moves to coords based on top right of machine bed, rather than front left.

I am able to create saved positions, however Z coords are negative and can not be set, even manage set coords does not allow the negative values.
I can now set saved x,y positions, and jog move in the correct directions.
z probe control sequence continues to work though.
if I instruct goto X0 Y0 the head moves to top right

regards

Dave

Understood. So this seems to be working as needed for X and Y. I’m guessing you’re happy with how that works then?

I can take a look and try to fix the negative Z coordinates not being flipped by the CNC machine toggle - that sounds like a remaining bug to me. Z=0 is with the toolhead at the top of the Z motion, correct?

Z does appear to be 0 will the head at the top of motion.

I am currently operational, however would be nice if I could get x0 y0 to be bottom left, incrementing to top right. similar to get the Z into positive space.

Z moves are always negative into the part, Home is Z=0.

Do you have a G54 offset? Did you try the CNC switch option?

25

been round the cnc switch etc.
z height used to be a positive value as had previously saved positions to go back to.
so do a z probe and save position to go back to.
now save position does not accept the z value

I do not have a Zaxis probe, so this is where somebody else needs to step in.
