Help with QTplasmaC

It is a little unintuitive, you need to pick Plasma Encoder then pick Arc Voltage from the "menu". It is the only item so it looks kinda odd...

Something like this in the HAL file:

With PlasmaC and axis I think you had to clear e-stop . (I have a hard wired e-stop only) Do I have to clear anything in QTplasmaC to get it running - the motors are locked ie enabled

You have Estop as an indicator so if the machine is in Estop then the indicator will be red, if it is out of Estop then the indicator will be yellow. If it does that then all is good.

How do you extract the parameters to get a new pncconf

If you have an existing .prefs file with parameters in it then PncConf will not overwrite it, nor will it touch the materials file.
If it inadvertently did then you could run cfg2prefs and redo it from your existing PlasmaC config.

You have Estop as an indicator so if the machine is in Estop then the indicator will be red, if it is out of Estop then the indicator will be yellow. If it does that then all is good.

More good info. Thanks.
The e-stop led is red . I will have to look at the e-stop chain .

I don't see an Estop entry in "# external input signals" in the HAL file

You need to add:

Ok
I think I have addressed all previous query's

I don't have an external e-stop linked to linuxcnc. The e-stop button drops out a relay to stop all motion.

I do though think it is an e-stop problem now.

this is what I had in the PlasmaC setup hal.
net estop-out <= iocontrol.0.user-enable-out
net estop-out => iocontrol.0.emc-enable-in

I still have the red light led. Re the invert for the Y1 axis I had it done with the motor wiring


Edit: I did invert the breakaway as it was showing activated

Edit 2: I have added the encoder code as well now it shows a voltage on the gui

You really should have a Estop connection into LinuxCNC

If you don't want to then change:

I wouldn't recommend this but...

Yes I agree I will put it on the to-do list

I can now power the machine on :woohoo:

We are getting there. I can now home X and Z But Y immediately throws A F error

I know I have not put the THC settings in yet so the display is showing around 600V

I think that I have all the settings for the Y the same as the PlamaC file that worked !!
