We recently purchased 4, Axiom Iconics for rapid machining of plastic housings used for respirators. We manufactured tooling to hold the housings and dialed the program in to make our cuts. Occasionally for no apparent reason the router will be off, sometimes .010" or more on Y or X, Z as well but very rare. We then need to readjust the program. We have checked all the hardware including the shaft couplers and everything is tight.
Has anyone experienced anything like this?
Were you able to make the router more reliable? & How?
Thanks for any insight!

How fast are you moving it? It's possible to out-drive steppers attempting to move faster than physics allows and they will lose a step. Perhaps try slowing down a titch and see if that resolves the issue.

Thanks, we have tried that already.

That's all I've got. The only time I've ever lost position was when I messed up and tried to force an unstoppable object into an immovable object.

Could it be speeds and feeds? -Causing tool deflection

dvfcorp,
I have six questions:
1. Is this problem happening on all machines? 2. What feed rate is being used? 3. What tool speed is being used? 4. What kind of plastic is being machined? 5. What kind of bit is being used? 6. Would you post screen shots of settings?
Lots of questions, but it would provide more accurate information for a diagnosis... Thanks, Bob

You could be losing steps due to static discharge (from dust collection)? Plastics cause more static electricity (in general) than other materials from my minimal experience in cutting them.

It could be electro magnetic interference or the grounding of machine. I had the same problem and received this information from Chad regarding adding ground wires to the i2R-4. It requires opening up the control box if you are comfortable with that. Give Chad a call at Axiom By the way it did fix my problem. Grounding i2R.pdf (411.13 KB)
