Help with new EMC2 config and 3 axis router.

There is a lot of information to absorb when starting up a CNC the first time. Many things can get overlooked in the flood. That's a smart move to have your motors uncoupled until you think you have everything worked out.

Are you using home switches?

For Z in my experiance the top of the material is Z0 and all the machining is done in a negative Z area. The limits I don't think make a difference if you go 0 to 120 or -20 to 100 unless you have a home switch and you want to call Z0 as the home position. Anyway when you touch off your tool on the material top you "shift" your machine coordinates so to speak. Once you have done that the DRO will show that you can go past your "shifted" limit but will not let you actually go past your real limits. Does this babble make sense? It is early in the morning here... anyway issue a G92.1 in the MDI command window and that will clear any offsets.

Also, from the Machine menu look at Show EMC Status and look at the actual position compared to the DRO position. Then do a G54 in the MDI window not a G92.1... need more coffee.

and it ain't working for me this morning.

Ok, I got it now. If you did a tool touch off of Z in G54 to clear that and make the dro read the actual do a G10 L2 P1 X0 in the MDI command window. I had to go out to the shop to see what I do on my plasma but it didn't help... so I searched the manuals till I found it
