Torch/code freezes after M03....


That is correct behaviour - the the torch is firing on the M03 signal BUT mach3 is NOT seeing an Arc-Ok signal so it will NOT move at all.

The Proma is either not sending or not seeing the arc-ok.

As a test, go ports&pins and disable Arc-Ok IIRC this should let it move without seeing the signal.

When testing, Mach is not going into reset or freezing is it - this can be a problem with noise from the plasma, if not, can you still jog it around AFTER trying a cut - is it still talking to the BOB/machine?

Just trying to rule out various possibilities for failure

I was advised if you heat them gently they should drop off.

Without stripping it, i don't know if the inner race is accessible due to the spindle nose.

In reply to myself, yes you can pull the spindle easily but only if the screw holding the Z drive adaptor does not protrude into the spindle cavity in which case it blocks the top bearing and the Z drive will need to be stripped.

Question - can i re-use the bearings on my R8 spindle on the QC30 spindle??

Back to the main topic

I have a possible option on a QC30 spindle for my mill, I have been weaned off the idea of TTS tooling by a friend so need to move to an ATC suitable spindle that has repeatable tooling - QC30/BT30

Can anyone verify this is a sane move IIRC the QC30 will accept BT30 holders without the locking ring (its missing anyway) ??

Also IIR you can pull the spindle on a BP out from the nose without touching the head??

If its not moving after pierce, check you are getting ARC OK  signal into mach from Proma and also that Proma is seeing the Arc voltage as being more than pierce voltage - there is a setting in proma for this. If its not sending arc ok that will cause the torch to freeze.

I don't think M1 & M3 should be flashing just the torch up, torch down should be alternately flashing and torch on should be on.


Is mach3 out of reset i.e. in run mode?

When I put my proma in test mode it shows arc on and up on proma and in diagnostic it shows torch up, torch on, no movement from torch though. When I run a gcode, it starts, moves to position, fires the plasma and doesn’t move, just continues to blast.

Don't jump ahead to live testing UNTIL you get torch moving up and down under test - you will dive into a world of problems, trust me, been there

Get torch bouncing up and down with Proma in test mode first - it must move or you on a hiding to nowhere.

That is correct, 0v, GND, -v are generally the same thing.
