Yes I redact that statement. A report would be helpful. I am no expert so I like to keep things simple. I still think a slightly modified macro should control this ATC easily.

I use only the outputs from my 1616 and none off the acorn. Here is my mfunc6 and wizard list. Example M94 /62 turns on output2 (not to be confused with OUT2)

you will need to compile it correctly and yes that is the right plc file. You are also correct about the ToolTurret being for a lathe style atc. Learning custom PLC can be a big time suck but understanding it will save a lot of frustration. Centroid is easy to use but getting my atc working ...

Mario did a whole series of video's on plc programming. Its a lot of information but I would give them a watch first.

I had to modify my plc.src to achive that. Please be careful if you decide to mess with the plc or wait until someone smarter comes along to help like cncnw :D also If you define a custom output like me, the wizard will remove it if you make any future changes to inputs/outputs. This is what I did ...

So just to be clear the turret rotates one way but wont reverse the relay to spin the other way?

You can press alt-i to look at and toggle all your outputs for testing, no need for mdi commands.

While memory bits are the preferred way to do things I also used simple input/output commands to the pre-configured file and it works perfectly fine too. Here is my frankenstein mfunc6, it has performed thousands of tool changes without a problem ...

I have 90:1 on my mill with 4000 Steps, works very well.

You can fit a harmonic drive on the stepper for high reduction without backlash.


Thanks Uwe, I have been looking for something with 45:1 or 90:1 and I cant find much. Are you using a planetary gearbox? Do you have a link? How much ...

Your axis configuration looks wrong. It looks like you are using the PM ballscrew kit. Are you are using the PM ballscrews? Mine have a 5mm pitch. 1in=24.5mm÷5=5.08 your turns per inch should be around 5.08 not 8 or 12.7
