Hey Chris,
Nice video! Nice LinuxCNC VMC!
I noticed that your spindle is indexed randomly at the start and end of
each rigid tapping cycle. This verifies Andy's assertion that LinuxCNC
only uses the index pulse to initiate rigid tapping and uses the other
spindle encoder signals exclusively
A couple of years ago I worked with the local Fanuc service guy on a
couple of machines and he mentioned that he was using Mach3 to make some
small simple routers. I asked him if he
had heard of LinuxCNC and he hadn't. After that, every pause waiting
for software to load was spent talking a

On my vmc, there is an untoothed belt drive between the spindle and
motor. The spindle encoder is on t
Maybe this thing isn't an encoder, the Fanuc PN is A02B-9000-0010, here

If you can't fix it, you don't own it.

I am not convinced that there is a rigid-tapping problem.
I believe that the cycle uses the index at most once

What if he were to add an index to the spindle. would that fix the rigid

The other way to do it is to keep the gearchange for the comand, but
for the feedback use a mux2 to choose either of the two inverse scales
and then use that mux2 output to set
Ohh,
Now I see what you mean, individual gearchange components for each signal,
That makes sense, still half to fully wrap my head around it to get it
configured, but I see where you were going.

You might want three of them, one for spindle command, one for encoder
velocity and one for encoder position.

I already have the gearchange configured, I was just trying to get the
feedback correct on the visual readout on the screen,
Do you think that under these circumstances, it eliminates the chance of
rigid tapping on this machine?

Gave those guys a call, talked to tech support for almost a half hour, 5

they'll tell you what it is.

I have a Fanuc spindle motor on the VMC I am retrofitting right now,
and I intercepted the motor encoder cable, with an ENCY card from Mesa,
the machine was open loop in regards to the spindle prior to this.
Would anyone know what the PPR might be on one of these, I didn't know
