Linuxcnc - plasma router - joint 2 flolowing error

Thanks, mr. Rodw ...i try post processor for sheetcam for Plasmac (i see on this forum )

So, please, can you some send me procedure, how calibrate the THC PROMA 150 ?

Many thanks,

Hi Tommy, you are best !! . It seems, that THC works !!!. I am very happy ....

Now .... i am newbie user of Sheetcam. I use this post for PlasmaC (github.com/DenkBrettl/plasmac_sheetcam_postprocessor)

So, i created some G-Code and now i try upload this to LinuxCNC and i have this error.

Why wouldn't you use the post processor from the author of Plasmac?

i don't know,,,,but i try it ......thank you Rodw

Ok, sheetcam is fine, now i have still problem with torch height.

If i cut some small holes, then i have the error " Valid Arc Lost" or "Float Switch Activated Program Paused"

I think, that if i try cutting through small steel plate (thick 2mm), then the problem is more frequent, because the steel still bended.

Maybe some bad settings .....i tried change the 'cut height' from 2 - 4 mm and 'feed rate' from 200 - 2000 mm/min.

If i tried cut for example "STAR" into big steel plate (thick 3 mm), then all is OK.


My last question is : the PROMA THC is set now for 162V. This voltage must be changed for different thick of steel plate or is the stable one value ?

Many thanks,

Additional information: I do not have a water bath yet ...

Hi, on my Proma SD I change the voltage settings for different thicknesses of steel. For mine with Hypertherm Powermax 45XP using 50:1 voltage divider; 99v for 11 ga, 103v for 7 ga, 105v for 1/4", 110v for 1/2".
