I have changed the x axis motor, with now I made up from 2 spares, mainly had to fit the tacho. The motor now creeps on its own. Could this be because the tacho needs timing? As I just plonked it in?

Dont know too much about tachos but think it wouldnt matter. Could be your drive needs tuned into the tach voltage if its slightly different from last one. However I think its more likely you just need to redo the offset in the PID tuning page of the CSMIO.

I've been trying to get the X axis working for a a few days and no luck still the axis moved to the right (when connected to the ip-a). I have tried the offset voltage, I find 0.18 moves the axis one way, and 0.19 the other, and it's doesn't let me save 0.185. Anything else I can try?

Did you get to the bottom of the tripping issue?

Since changing out one of the motors (this x axis) the machine has not tripped the breaker, although I've not had the axis running for more than a few seconds. As after about a second the mach3 reports a PID fault I guess as it wasn't expecting the axis to move.

However, I only noticed the problem with the motor when I ran my first G code program.

Could you have the encoder the wrong way? Try inverting the encoder in the CSMIO plugin. See pic

I've had a few days off this as the wife has had me decorating the kids rooms. I've now managed to stop the motor creeping so I can now start with the tuning. Hopefully I'll get this cracked on the weekend so I can then move on to the VFD for the spindle motor

What was the cure for the creep?

The creeping issue I think was mainly my lack of understand on the software interface. I have since learned that the value for offset, may not be the actually value saved. You can type a value in two 3 decimal places, and click apply, and it does save. Simply with playing with this value I resolved my problem.

Yesterday I spent the afternoon cleaning out the sump where all the coolant is kept, There must have been an inch of 20 year old crud in the bottom  Not the nicest of jobs.

Can anyone recommend a coolant fluid?

Ok, I have never typed a value in that box, I just pressed the button and the control set the offset required.
