General Mach Discussion / Re: Help with Plasma G31 Probe On Floating head

« on: April 30, 2015, 03:24:21 PM »

Looked under the help/ and my name was there so its not in demo.

Used the G31 Z-2 F5 code and the Z just zeroed and never drives down to touch off.

The probe led didn't light up to tell it that it touched off.

If I trigger the switch the probe led lights up.

The LED turns on when tripped and off when not tripped.

I'm almost positive that I loaded the .dat file in the mach3 program, at least I don't get any messages saying that I'm running a  Demo.

No outside controller, direct serial port.

This Is the G31

I've tried probe in G31 and home in G28.1 and neither zeros the Z when its tripped or stops moving and I've changed the min max.

I don't know if this is a post issue? 

thanks

I figured out that the switch ground need to be isolated from the motor controller ground and that stopped the rattling on the X and Y.

The home switch lights up when triggered but the Z still keeps searching for home when tripped.

Here are the settings I'm using in config:

Input
Z Home Enabled/ port 1/ pin 12/ active low disabled/ emulated disabled/ hotkey 0     

motor outputs
Z enabled/ step pin 6/ dir pin 7/ drlow disabled/ step port disabled/ step port 1/ dir port 1

motor home soft limits
Z reversed disabled / soft max 100.00/ soft min 100.00/ home off 0.0000/ home neg enabled / auto zero enabled/ speed 20

Plasma THC300-G31

If you see any thing I need to change let me know.

Thanks,
Dave

Thanks, i've tried using Z home for the floating head but when the switch is tripped the z-axis continues moving and the X and Y axis start to rattle as long as the Z home switch is tripped.

   I have the limit switch on the floating head set as a probe, when the torch moves down to touch off and the limit switch is tripped the head still moves down and the X and Z axes start to shake. Not sure what the problem is with the X and Z but I've got something going wrong.

Thanks
