Mach4 Toolbox / Re: problem about tool change M6

My mistake, I was thinking it was Mach3.

Lots of pictures for us to asses first.

We need lots of pictures of the parts and current setup before we can help.

You will need a Mach3 plugin for that to be possible and I don't think they do one.

Your other option is a new breakout board or motion controller.

Most 3d work needs a ball nose cutter, I would check your CAM software because it sounds as if its expecting a ball end.

You need to put your M6Start.m1s on here for us to look at but rename it to ahmad1222.m1s so you do not get a error message saying already exists.

Are you using a ball nosed cutter?

you could use one of these with a small magnet glued to the spindle.

This might be worth a read.

The encode may have an index pulse, called the Z channel on some that you could put into a normal input on the PMDX-122.

The smoothstepper has port 3 for this use or CS-Labs can do it as can Hicon some of the later PMDX boards too, you need boards that can read high input rates most spindle encoders are 1000 PPR and more so that x RPM is way above most basic boards, you need one with on board processing.
