Plasma fires on any axis move + no THC. Please help.
« on: December 13, 2016, 10:45:30 AM »
I am using Mach3 for plasma cutting.
The torch is firing any time the xyz axis move. This happens when running g-code or jogging.

I'm using this BOB: http://www.ebay.com/itm/5-Axis-CNC-Breakout-Board-For-Stepper-Driver-Controller-mach3-for-Arduino-/400347266412

This is my cutter: http://www.everlastgenerators.com/product/plasma/powerplasma-60s

I'm using a proma 150 THC (Although I can't get it to work either)

The PowerPlasma 60s has a CNC port and i have pins 1&2 wired to the BOB relay-switch. I have the jumper closed on the BOB.
Mach3 / Spindle Set Up / Relay Control set to Output 1 on CW and CCW and
Output signals / Output #1 Enabled / Port1 / Pin17
The torch fires on any axis move but doesn't respond to M3 commands.

I've also tried Output 1 - Port 1 / Pin14 & PCGround - under this configuration it did fire with M3 commands but also fired under any axis move.

Jumping the CNC port's pins 1 and 2 together fires the torch.

ALSO: The THC isn't working either. All pins are wire as diagramed. In Proma test mode and Mach-Diagnostic the Torch ON-UP-DOWN LEDs are simultaneously all ON or all off depending on active low or high. The LEDs don't change with the proma. I have the Proma wired to pins 10,11 and 12 on the BOB.

Please help. I've watched every youtube video I can find.

Check your settings vs the above manual.
For imputs to function you must have 10-24 volts going into the bob.
turn off your power supply to motors.
turn off plasma machine
open mach3
 when you power on the bob note the leds lit on the bob. use the torch on and off button to toggle the relay or mdi
look and listen. do you hear the relay click and the 2nd led light up.?

Thank you BKTeater, that worked for the THC!
The torch was still firing on any axis move but not under M3. I designated the spindle control relay to output 2 and then enabled output 2 (instead of 1) and designate pin17 (exactly like it was for output 1) and behold it works. I can't figure out why that worked...

Good glad i could help. Im still trying to get the thc perfect myself. its pretty low cost so its only going to be so good.
and yea, strange sounds like something was shorting out and closing the loop somewhere.
