I didn't find the XHC HB04L for sale anywhere...

TDAY, I fixed mine by enabling MPG0 in the Mach configuration. Be sure to configure the X, Y, Z selector buttons via the ShuttlePro configuration to enable the both the MPG0/Jog axis.

I can confirm TDAY's report. The inner wheel on my ShuttlePro is no longer working after I upgraded to Mach4Hobby 4.2.0.2914 either. I was using the previous version 27xx? and everything was working fine.

Daz, define what you mean by "setup the mpg in the mach config". I have the *********tlePro plugin enabled. But, I do see MPG0 through 9 (or so) in the Mach config. Is that what you're referring to?

The ShuttlePro has its own setup where you click a button on it and set what that button does. Moving both the inner and outer wheel doesn't bring up anything here though, so I can't use that to program the ShuttlePro.

I appreciate everyone's help, but please read my posts. It works fine with Mach 3. Mach 4 i get weird results.

Accl parameter is definitely not the issue either. Since my pocket milling isn't working, I use a boring head to finish the hole. The finished hole is precisely where it's supposed to be. If steps were missed, then the hole location would be wrong.

I believe backlash is also working correctly too. If it wasn't working correctly then, again, hole location would be incorrect.

There's some other issue. And, no, it's not a worn out or mechanically loose machine!

Personally, I don't see how the accl parameter will change anything.

No, the units are fine.

I'm using smooth stepper. Clearly it was using the backlash compensation in Mach 3. Anyone know if the versions for Mach 4 are using htis?

The other issue is the undersized holes, about 10 mil too small. There's obviously something else going on!

And no, it's not spindle play. As I said, the holes were fine in Mach 3. Something has changed...

ok, I'll try. I have an open loop machine. I suppose if accl is too high, it will just lock up.

Is there a rule of thumb in setting the accl?

I can say that all parameters (accel, etc) are the same between Mach 3 and Mach 4. It worked well in Mach 3...why doesn't it work well in Mach 4
