same problem here when i load file in mach3 it wont make some of the holes it just go to them torch on then tort off and move to another one
@ahmedmolla - Your case may be a similar symptom or problem but does not appear to be the same cause and solution as the OP. In your case, your drawing has a toolpath for every shape, the OP case does not.
If your torch is positioning to each shape, moving to pierce height, firing, then OFF, it could be that your pierce height is too high so the arc never transfers to the material. Try lowering your pierce height.
If that is not the solution, then please upload your gcode file here as an attachment.
so the problem is not in the height cuz on all files i have same height and on older ones it work fine and another side is that the torch burns through material and then stop .and cant upload the file cuz it say im new member on forum…
I’ve got your support.zip file through our email, having a look at it soon.
After some review of your backup .job (original .job was not saved prior to making support.zip), the pp, and the .tap I don’t see any obvious errors. The only aspect that stands out is that you are using pp var bigarcs = 1, which will cause arcs G2/G3 to often times represent circles in one stmt like this-
G03 X37.3986 Y92.6014 I7.6014 J-7.6014 F120.0
You are also using 4 decimal places in metric mode and no leadin.
The combination of all three conditions may be causing Mach3 controller to have difficulty determining if the motion is a full circle (which is the intention) or if its a very very small arc (which is virtually no motion, which is the erroneous behavior). I’m guessing but it seems possible.
I changed the pp to use-
post.SetOptions(post.ARC_SEGMENTS)
rather than bigarcs var which has been deprecated some time ago. ARC_SEGMENTS limits arcs to 180 deg, and usually circles will be coded with 4 arcs just to stay away from the limit.
