That worked, thanks!

Not sure if this is the right forum. I'm trying to generate some pretty basic output from Bobcad-Turn, and what looks like a normal tool path in Bobcad has all sorts of extraneous movements in Mach. Bobcad support calls it "Crop Circles" and they seem to think it has something to do with my Mach setup, since it doesn't show up in their sim. I can repeat the results with a default Mach3 install, though. They suggested I post Bobcad's output here to see if anyone knows what is wrong with it. I attached the output and a pic of what Mach sees when I load it. Thanks in advance - Jeff.

Uh, never mind... It was user error. I dropped the license file one folder off when I reinstalled everything. I remember reading in the threading docs that it was required, but didn't think to check it. I was actually playing with the new XML viewer when I spotted "demo version" and guessed immediately what was wrong.

Hmm, I may need to cut off a second toe.... Now it always stops on the g76 line after getting an index pulse. I tried switching to g32 mode, but it does exactly the same thing.

I returned to using the CNC4PC index pulse card, mostly because it produces a nicer wave on the scope. I cut a large, 10 degree, slot just in case there was some sort of read issue that somehow affected the sync pickup and not the RPM DRO. True RPM is very accurate and matches what I see on the scope perfectly. I've tried running as slow as 170RPM and as high as 780RPM with the same result.

There are some old PCS piled in a heap at work. I'm considering grabbing one on the way out tomorrow and trying that to see if there might be something wrong with the PC I'm using now. I know that doesn't make a lot of sense, but I'm out of ideas.

I also figure I can have the gearbox and lead screw back on the thing in about 30 minutes. I have one part to make for the mill I'm CNCing, and that project has stalled waiting for me to figure out this one "small" threading problem :)

That fixed it. The last time I uninstalled everything I must not have deleted that rogue mach.sys driver. I deleted that, uninstalled Mach and deleted the folder, then restarted just for good measure. The new installation stops on the g76 line like it's supposed to. I haven't had time to reconnect the hardware, though. I've used up my play time for today, so I'll work on it tomorrow.

Thanks for all the help. And thanks for the lazyturn tip. Another new toy... it's like Christmas :)

No, sorry. I've set it up for others, but never got around to getting a mic for myself...

I don't have a problem calling, though. It's free for me anywhere but Asia...

It doesn't stop at the g76 line. I just disconnected the PP and loaded your XML...

Do I have a bad installation or something? When I went to 033, I uninstalled and deleted everything Mach3 related on the drive, then install 033. I reconfigured all the inputs manually rather than using an existing file. However, I did copy the wizards from the original installation.

I can give you a remote desktop connection if you're willing. With the PP disconnected, nothing can move and get broken :)

Er, if I disable the index, the thread routine does hang as expected. If I map it to an input, any input, it functions as if it's getting a signal. It makes no sense to me that I can map the index and estop signals to the same input, and get an index signal without also getting an estop signal.

It took me a little while to figure out I can't disable the estop input. I just assumed it worked when I clicked apply and closed the dialog. Mach3 must re-enable it somewhere along the way :)

With the controller off, I switched the estop input to active low so I could make a dummy run. It still appears to be getting a trigger. The wait for trigger led comes on then goes off half a second or so later, and the output shows it is making a threading pass. The index input is still mapped to the same input as estop (also active low). The index led never comes on.

I have one sensor in my hall effect sensor. It has 3 wires: power, ground and sink. I get one pulse per pass with a magnet.
