Homemade, cheap, plasma CNC

Thanks Tommy, I’ll try that tonight when I get down to the shed. 

Still not working,

linux configuration safe height 20 (as per tommy suggestion), Sheet cam rapid clearance 30mm.

Z axis drives down, slows to probe, probes and cuts, goes up 8.4mm ( no idea why it only goes this high) travels to next cut, goes up, begins probe.

 

Hope this is everything. About to run back to the house, just had a storm start here. We have just spent the last week in flood. aaahhhhhhhhhh



z axis from .ini.

Thanks guys,

I have changed the safe height to 100 and still get the same error. 

The z axis only goes up to 8.4mm before travel. And gives the warning after the first cut of a job. 

No doubt I have set something, somewhere and now I can’t find it to fix it. 

Thanks Phil,
