New Build, Aluminium Frame Router/Mill

Main concern was the error code pointing towards motor phase short, not current overload etc, I'll check the manual but i don't think the short setting would be adjustable?

Might be a long shot but have you checked the motor connections at both ends

Not yet but will pull it apart this weekend.

Been working well, last week did a 5 hour run of parts :)

Today i had one part and the blasted spindle cut out 4 times on me, luckily as i don't trust it i was close enough to e-stop each time and save my cutter.

I can't see any loose wires and its the same vfd message each time :(

Not sure what i can check really?

Ok, pulled it apart and rewired the VFD relay into Mach3, if it faults now it will throw the Cycle-Stop button so at least that will save any more busted tooling.

Not sure what the real cause of the drop-outs is but at least i can walk away from it now.

So far so good - no faults since wiring changes :)

Did have a probing error though - setting up for engraving plastic, 0.2mm 30deg 3mm tool in, tested the touch-plate as i always do, pressed the Z-Ref button, tool comes down and just keeps on going - pushed that little carbide bit through the pcb touch-plate, through 3mm of engraving plastic and a couple of mm into the machine bed :(

By the time i had hit the e-stop, the stepper was stalling, no idea why, i rebooted and it was ok for the rest of the day.

Scary stuff.

Dave, I had the same thing happen to my touch plate, it's got a 3.175mm hole punched through it, the 18mm MDf base and into the Ali bed....mine was because the earth wire had become unattached. Just goes to show how much power these things have, wouldn't want my fingers (or anything else) in the way of it! Needless to say I watch the procedure like a hawk now with one hand on the 'o'shit button...just in case!

I have had a similar problem and not got to the bottom of it I am now thinking that you should put a crock clip on the tool to ground as you probe because you are relying on the bearings in the spindle. It just does it very occasionally.
