4th Axis rotation angle limit problem

Oe, that is dazzling

Let me give some of my basic here I left those out before:

XYZA configuration, nothing else configured yet (though I did try).
Spindle turned on manually

Want to try out milling acetal bearings with the 4th set up as a C-axis.
I have the contour ready to be milled in XZ plane and it shows up in axis.

I want to get my C axis to turn before the XZ movement starts and keep on turning untill all XZ movement is done.

It would be awsome if I could switch between position mode and velocity mode as it would open up a lot of problem solving options but for now I need to test if I can even make the bearings I have to make.

What do you think would be the quickest/best way to get there?

Oh boy, I feel so close to my goal yet so inapt to folow your lead...

I understand the basic of what you say and I think that I can use stepconf to make the configuration that includes the spindle. Beyond that I get lost in the technical lingo.

Do I set up all the pins for the spindle or can I leave some out because the stepper will not use them all?

Then, how can I make it the easiest for you to help me get to the finish line?

Well, gave it a start but find myself lost... searching for answers only offers up more questions...
There is so much information that I can not make sense of it..

Is what I am trying to do so unusual that it is not standard in cnc-ing?

Ok, awesome you (and maybe others) are willing to have a look!

Here is the sample config, made fresh from a working 4axis configuration, just the spindle added.

Thanks a lot Andy!
I'll give it a spin tomorrow.

Hi Andy,

Gave it a try, the 4th will not move but the spindle controls in axis say the "spindle" does respond.

I tried to look up if the pins are ok but could not find any reference that seemed to be incorrect to my very limited understanding

I noticed that on line 8 of .hal you give loadrt stepgen ctrl_type=p,p,p,v step_type=0,0,0,0 where I would expect loadrt stepgen ctrl_type=p,p,p,v step_type=0,0,0,1. (expected because of reading it, not understanding of any kind..)
