Can I manually set the home positions with Repetier? In other words, jog each axis to where I want them to be considered home and then Zero each axis without the machine trying to go to home? (No home switches).

Once your home just type in G92 X0 Y0 Z0 and press send. (or G92 X100 Y100 Z0 etc)

That is what I initally tried but my coordinates in Repetier Host do not change to Zero unless I actually press the home Key.

With the newest host version you can. Jog to your zero position and send the following;

G92 X0 Y0 Z0
@isathome

The last command is for the host to tell you are at zero position, so visual coordinates/drawing matches data printed.

Thanks

Not using @isathome, if I have all my axis showing 100, and I issue a G92 X0 Y0 Z0 then the Y Axis will show zero in read, but X and Z still show 100. So for some reason Y is being changed on Host but not X and Z.

Then entering @isathome X and Z go to zero (in black) and Y is zero in Red.

I don't know if that will affect anything it's just odd behavior.

The color is not that important in this case. With the next y move it will get black. Colors are only updated, if the value changes. So if it was 0 before but red, it is just not repainted in black, because it didn't change.

Okay, I understand the color isn't that important. The Oddity that G92 X0 Y0 Z0 will reset the Y axis to Zero by itself but the other 2 have to be zero'ed with @isathome. Just curious why the Y seems to update to zero and not the others.

Uups, will check that G92 behaviour when at home. Perhaps I just forgot to set the other two??? Anyway, with @isathome it should work.
