Can't get lathe to Feed

I'm teaching you to suck eggs here!.
I've just looked at the HAL carousel componet (Which I never knew existed)
and its been written by a guy called Andy Pugh. Thats a coincidence, because thats your name as well !

If this helps:- Boxford 125 PPort no sensors on the turret With help from Andy and Aciera

Yes, looking through a previous thread it seems that the carousel component isn't particularly useful for the Boxford TCL. However there is an existing component for the job.

I suggest reading from that point, and then stop when someone starts talking about sensors in his toolchanger, as that's a thread shift to a different changer.

I've been away from the project for a short while wilst I dealt with something else.
I have the encoder set up on the lathe and have performed a simple test for signals using the LPT port tester, and it is working correctly.
However, before I continue I need to set up the spindle speed control and will need some guidance understanding PWM. I will start a new thread on this topic before returning to this one in order to continue.

I've added the below section to my .HAL file but get the message:

encoder.0.update-counters base-thread NOT FOUND

I'm getting a little snow blind here, can anyone point out my error?

It appears that there is only one "encoder" module which updates all its channels at the same time.

So change encoder.0.update-counters to encoder.update-counters (and the same for capture-position)

Thanks Andy, I'll give it a try but it will be later or tomorrow now. I was actually looking at the '0' and wondering if that was the issue but I didn't want to mess with it until I was sure.
