plasma switch offset

Post by kohlgren@gmail.com [sh... »

has there been an update to sheetcam where the switch offset is now in inches?
my switch offset is 1.32 mm or 0.052 inch
in sheetcam post processor setup i entered 1.32 mm back in october 2013 and have not changed anything there
when i post processed a part yesterday and ran the part in mach3 the torch head raised up to 1.32 inches, reset z axis to zero, raised up another 0.08 for pierce height and fired the torch 1.4 inches above the plate
it took me a while to figure out what was happening, had to go into gcode to see what was going on
this gcode is platemarker, but it is the same for plasma
needless to say the scribe didn't work well 1.4 inches above the plate


here's the gcode

N0250 M07
N0260 G04 P1
N0270 G01 X6.3500
m09 <------- still have to manually enter m09 to retract/turn off the scribe


i ended up typing in my switch offset as 0.052, even though it clearly states enter in MILLIMETERS even if you run the machine in inches
funny thing is; my scribe offsets are still in millimeters within 3 lines of each other in the post


my new gcode is

plasma switch offset

Post by Les Newell les.newell@... »

All of the switch offset stuff is done in the post. Edit your post and look for function Reference(). This is the switch offset code:

   post.ModalText(" G92 Z0.0\n")
   post.ModalText (" G00")
   post.Text(" Z")
   post.Number (switchOffset * scale, "0.0000") <--this is the important line
   post.Eol()
   post.ModalText(" G92 Z0.0\n")


That scale variable controls metric/inch conversion. If it is missing the switch offset will be output as metric even though your code is in inches, which would explain the symptoms you are seeing.
