I've been having a problem with my DM-2 not orientating following a lower RPM tapping operation, but today I had it do the same thing on a drilling operation where my RPM was only 600 rpm.

What happens is the spindle doesn't orientate and then it does a tool change the tool drops because the spindle isn't orientated.

I had already posted this issue a few weeks ago, but now that it appears it has more to do with the RPM verses the tapping operation I figured I would create a fresh new post.

I'm guessing there must be a parameter setting that's causing it not to orientate on a low RPM ?

I don't know what the breaking point is as far as how low the RPM needs to be for this to happen, but I just tried the drilling operation with an RPM of 1,000 and it worked fine..... ( so it must be any RPM lower than that )

Any thoughts or suggestions ?

Thanks,

Kent
