Hi, how and where can i remove safez distance? On rotary cut i don’t need a safez distance, it causes trouble with my thc unit by going back down to zero after the external thc unit already set the new cut height. My rapid clearance is 0, Cut and pierce also 0. I have to replace the safez value in the Gcode after post-p.
I also need to change the rapid movements between cuts to rapid move 1 axis at a time and not x y and c at the same time.
Is this possible?
Any help would be much appreciated.
I don’t know of a good way to suppress safeZ rapid motion in a rotary job in all cases, specifically those cases of rectangle and i-beam objects being rotary cut. Round (cylinders) on rotary axis should be relatively easy to do though, endZ will always be safeZ + the cylinder radius, you can test for it in OnRapdi() and thus suppress the posting of that case.
I’m confused as to why you need to do this though. Perhaps its that you are not zeroing Z on the center of the rotary axis, which is what sheetcam expects for rotary jobs.
Depending on your controller brand, sheetcam’s rotary G94 feedrate value may not be correct. For that reason, we have built an exemplar pp using a G93 Inverse Time feedrate mode, along with other rotary options such as zeroing Z on the surface of the rotary object when A=0 degrees. - Post Processor Example w Custom Options popup window
I use a fangling 4 axis controller with a XPTHC-4H independant height controller bolted on to the Z axis ballscrew bracket. Z 0 is set false for top of tube in sheetcam fanglingRotary. The problem starts from the second cut when z lift to safeZ and theb the thc preforms the ihs and set its own new cut height. After ihs has set the cut height, the arc starts an then the z axis screw moves down to 0 and the thc screw moves up back to set arc voltage height. This causes a torch crach every few cuts.
I need to change the setup for z axis to move back to 0 before the ihs start or change the value/formula for safeZ.
I have no idea where to make these changes or how to suppress onrapid().
Please if you can assist me with the changes
Thanks
