This might sound stupid but here goes, My motors steppers have four wires from them and are for about 6" not shielded.   Just bare wire connected to a plastic terminal strip that joins a four wire shielded cable to run on to the controller.  My controller uses plastic terminal strips that plug into the board they are green and l shaped so they can only be connected one way.  the wires feed into the screw terminals at the back side of the block and then is plugged into the connector on the controller board.    With all that said I have about 6" of bare wired exposed to any noise that might be around.

Yes I can do this, Three separate Gecko drives one for each axis.  Are you thinking it might be the drive?

I need to give you the exact steps it did.  Thehead moved up above the work piece.  relocated to the next position x-y then the head moved up again then down at this point I was above the work.

I actually watched the Z move up stop move up and then down to begin again.  That is how I knew we were in the weeds so I ran and stopped the program looked at the DRO and it said I was cutting .062 deep and was about a 1/2 inch above the work piece.

the dro showed it to be in the correct position.  However it was at least a 1/2 inch too high.

Yes the Z was retracting to move to the next spot on the letter this would have been a 1/5 move up toy relocate same cut then down to start again it was carving the letter.  It has cut the back side of the s and the bottom and was moving to cut the top and join the bottom for opening the letter.

I did run the driver test too.  I saw an occasional spike of around 60 once in a great while other than that totally flat.

Okay, I just5 got back in from the shop, cut the Accel in half to around 5-6 now started a job, same job posted cutting the S lost in space.  Head moves up an additional move looked to me "I actually caught it this time" then moved back down and began to cut in the air.  I am just not sure what can cause this sort of problem.  I checked the mechanical on the Z axis for ease of movement and it's fine no obstructions nothing.  I cut at least 7 jobs similar without a problem then all at once this starts and in the last four Jobs I have lost at least four pieces.

Oh yes, one more thing, My Z axis is set to move at 30 IPS is this too fast?  I guess as I think about this it's after a plunge of 1/8 single cut I see this happen, I can't say for sure it's every time though.  It will always catch me when I am not looking.  At this point I feel like I just can't leave the machine to do it's thing and move on to t=other things prepping the next job etc.
