Troubles to get started with SD240 Retrofit

Category: Turning

So I set the jumpers on the 7i33 for X- and Z-axis to TTL (DOWN) and entered the USE INDEX- YES in the INI. Both axes behave normal and I think they home with using the index now.
Sequence:
Homing movement
Home switch trips- "home sw. X" gets yellow, "enable index" lights up yellow and the axis moves forward a bit further.Then the "hm2_7i80.0.encoder.00.input-index" flashes yellow very short, the axis frees the home switch and moves on to home-pos, stops and "x-axis homed" lights up yellow and the DRO says 0/0.

Z homes the same way. 

I think thats exactly what I wanted to achieve- correct? 
The spindle I guess can be indexed also, otherwise threading would be impossible...but the spindle likely just needs the index, A/B will not be necessary on a lathe- or am I wrong?
Well lets see how the next step can be solved.

The important hint was that the 7i33 just can process ALL inputs as TTL or ALL inputs as differential!
Thank you all so much

Hi, please share your config files. If signals can be seen in Hal Meter there must be another config issue.

Here's a basic try at this using the stepgen mapping:

0 = X
1 = Y
2 = Z
3 = A

Thanks, Aciera. I'll check with Cofhal. He had a setup that seemed to work well. Spumco hasn't said anything since... I plan to give it a try before Christmas (purchase of a 7i96). I'll keep you posted. Thanks again for the feedback and your efforts to make this C-axis fully functional.

I've replaced the standard kinematic file with your modified version, added extra joints and changed the config to inches to test in the simulation but I cannot reproduce your jogging issue in TWP mode.
I'm afraid I'm a bit at a loss as to how to troubleshoot this further.

Thanks so much for checking it out.  I'll play around a bit more and see if there's anything I can find.  I'm just working on a vismach sim of my actual machine, so I'll try it out on there and see if I can replicate it.

Sorry for only getting back to you now, but I've only just had a chance to try it out.
When I insert this:

setp    hm2_7192.0.encoder.00.index-enable true

and comment out this:

net x-index-enable  joint.0.index-enable  <=>  hm2_7i92.0.encoder.00.index-enable

I get an error message when starting LinuxCNC.

The complete section for the X-axis looks like this:

Maybe the real sensors have a different polarity to your bench test setup?
Halscope should help understand what is going on, if you scope the inputs and the carousel.0.state (with reference to:
