So my 4x8 with Candcnc bladerunner package is up and running. I made some cuts last night and mostly it seems to be working fine. However I have some bugs I need to work out.
I have set up the z axis offset in Sheetcam to 3.556 mm (.140") which is exactly what it is. When I run a g-code form sheet cam my pierces are weird.
lets say I have it set up to a pierce height of .250" and a cut height of 0.07". then cut at a voltage of 134. The Z will touch off, correct for my offset, raise to .250" and pierce with the correct delay, then plunge down into the material for a half second or so until DTHC takes over and raises it to 134v or (which is the correct voltage to cut at .07")
So basically, my switch offset works, my pierce height (.250") and delay is correct, but I have to set my cut height in sheetcam WAY higher (like almost as high as pierce height) to not plunge into the material until DTHC takes over??? I don't get why it would do this, Z has zeroed itself already with the correct toushoff sequence, then plunges way too far until DTHC takes over?
My other issue is jogging. It's something to do with the limits. My table is wired so all the limits on the x and y get joined together, with NO limits tripped in mach or the table I can only slow jog (10ipm) but when I trip a limit, hold it down, and reset mach, I can fast jog (100 ipm) with the limit light on???? WTF? something must be reversed there. I tried reversing the polarity of my X++ and y++. That let me fast jog (limit light on all the time) but when I went to cut, it faulted because of the constant limit setting.
Arrgghhhhh I would GREATLY appreciate any help or suggestions, I will get a code snippet from my pierce sequence next time I get out in the shop (likely saturday)
Thanks guys.
