General Mach Discussion / Re: My spindle keeps shutting off randomly.

« on: February 09, 2015, 02:41:16 PM »

Ok... finally getting somewhere!

My machine is a IHCNC turnkey (using their term loosely)

I called Factory Automation. .. great people by the way!  My VFD was hooked up to L1 and L2 from factory.... L1 and L3 is what it is supposed to be.

It seems to work!  But.... it uses a 20 amp breaker for control cabinet on off switch. At full RPM no load that breaker will trip after 10 minutes of running. Breaker is getting warm... not hot... should I just replace breaker... or do I have bigger problems?

I also just hooked voltmeter to the V and W directly at spindle motor.  The spindle started all by itself even though Mach3 reset button was still flashing!

Why did that happen?

I just checked the line in voltage.  It varies from 213 to 215 ac. It doesn't fluctuate when spindle mysteriously shuts off.

I'll have to try and figure out how to measure the 200v dc you mentioned above

This is a Teco FM50 VFD. And I just replaced VFD with this one because the original VFD was doing same thing... so it's definitely not VFD.

I tried to monitor incoming voltage but it's hard because this problem is very random. 

Is there a procedure to check in coming line voltage?

Running a ethernet SS, no rhyme or reason spindle will randomly shut off. VFD shows error of low voltage control.

Are there debounce settings in SS config... or any changes I can try in config to help?

When the issue is so random it's hard to trouble shoot

What bit did you use for the engraving?

^^ yes all of the above.  I think madcam uses lines instead of arcs. It cuts awesome in the newfangled wizard... have to check my settings in Rhino and Madcam

When I mill parts in Newfangled wizards they machine beautifully.

When I mill using my CAM package (Madcam) my 2d cuts are slightly rough.

I just had a thought. .. I'm using backlash compensation. .. is that not showing in my CAM post?
