Hey guys...

This Nano and Roger at AMSL..we are having the same problem we did a couple weeks ago....the bit stops turning and the feed continues.

Replacing the frequency converter worked great!! up untill yesterday

I will call tech support after 7am...any other suggestions would be great.

Also..we never got any feedback as to the disposition of the frequency converter that had been replaced(what was wrong with it etc....)

Thanks

Roger/Nano

One thing to check in the actual cnc program, would be to make sure that there is an \"M31\" within a few lines of code after any tool changes. This ensures router is up to full speed before continuing cut. If this line of code is not after each tool change, it is possibly that the spindle could stop and the machine axises could continue exicuting program.

Nano,

Are you incountering this with CN or MV files? I think Ryan may be on to something here.

Hey guys, It still sounds like you may have an loose armature wire or a neutral wire in the control losing connection somewhere. It may have ran for a while after you replaced the frequency converter because the wiring was moved around. Now, the same problem has come back. A technician is coming there on monday to check it out.
