Thanks guys I will look into further down the line I was just wondering about it as I see some do both for probing ohmic primary and backup the float switch.

I missed this

Line 190 of thc.hal:
net LimitZ parport.0.pin-15-in => or2.2.in0
expects a limit switch on parallel port pin 15, do you have that?

if not you could try changing the line to:
net LimitZ parport.0.pin-15-in-not => or2.2.in0
or even commenting it out but I have no idea what the repercussions would be...


Thanks Phill I didnt see this reply I might of skipped it but this worked thanks

Is there any way to make the torch go back to home location after cut. Pretty much the spot where you home it before it starts cutting? I want the torch to go back to home location after my cuts.

Just add G0 X0 Y0 before the last M30 in your file but it might be prudent to also add another G0 command to lift the Z axis to a safe height before this (ask me how I know?)

I would venture a guess at collisions !
Inkscape does that always, in that it adds a G0 X0 Y0 Z0 at the end of every gcode file.

You can't use Z motion as the PlasmaC GCode parser will comment them out.

You just need to ensure that your safe height is really a safe height then put a G0 Xnnn Ynnn move after your last cut.

Edit: Which has just shown up a bug in the GCode parser, it isn't commenting Z moves correctly. :(

Sorry but I didn’t know Inkscape had a cam feature?

Inkscape comes with gcodetools installed and ready to use, it is very useful and does pretty much everything for 2D and some things for 2.5D milling/cutting/laser/plasma.
