My spindle will run and stop just fine up to 850rpm but any speed above that and the regen resistor kicks and slows the spindle slightly but then cuts out and allows the spindle to coast to a stop.
I have had a look through the parameters and...
I was sitting in front of my Arrow 750 the other day, deburring a part, when the external regen resistor burst into flames. I quickly hit the emergency stop and the flames died down and the resistor cooled off.
The next day I was able to make the spindle do its thing. i.e. spin and stop as it...

Remedy: Correct device...

The problem just came out of nowhere, or it might be attributed to a...
Hello Practical, around about this time last year I started out my CNC adventure with a little Chinese CNC engraver and Mach 3. Well, I've taken a bit of a step up thanks to some crafty ebaying and a big dose of naivety and got my hands on a... well you already know because you read the title.
