Changed to AxisGUI (as I don't know how to set up Probe_Basic) and commented out the POSTGUI_HALFILE (as I got start up errors about missing hal pins) then tested in current master on a non-rt RIP installation. Seems to work fine for me.

Well, I know what TTL & PWM means. The problem is, that TTL (in this context) only means 5V while PWM is just pulses with no indication to voltage or frequency.

The manual of the Atomstack M100 just says 5V TTL. I googled, but did not find any good indication if they meant 5V analog or PWM. Usually (YMMV) more devices work with analog than PWM, so I went that road.

If, from your experience, TTL in this context means PWM, I'll happily take that advice. If you remember, you explained to me yesterday how to flash the second PWM output. So this has already been done.

I'll look up in the manual how that needs to be wired and post it here.

I am following the directions of the documentation. If it was mentioned then I would follow your route.

linuxcnc.org/docs/stable/html/motion/switchkins.html

Is there documentation elsewhere that will be a bit more correct?

1. Do I need to wire up the enable inputs on the stepper drivers?

1.1. The 7i76 does not have an "enable Pin" on the step generator. So I then need to hook up enable to any normal I/O?

2. I noticed that I can get a higher top speed when I reduce the accelleration and at lower top speed I can put in higher accelleraton values.
 For a small bench top mill should I rather focus on acceleration with lower top speed?

3. Is it possible to generate a 4th axis in PNC config? I did not find it yet. Maybe someone can point me in the right direction. Do I have to add this manually to the HAL file?

1. No, it will do just fine without, if you do not plan to move it manually
1.1. Yes
2. Don't, just don't! Set the machine up, make it work with very low values, then you can decide what is better for you after you get some experience.
3. Yes, on the third page choose XYZA

Nice little machine.
Keep us updated.

using the switchkins example ini settings and sub files. my config is an experimental setup in a work in progress branch in probe basic for multi axis simulation. not sure you would want to dissect through that to hunt down the issue, but here is the github link to the branch if you do!

Moved to "driver boards"

Never used a 5i20 so i am refraining from dispensing advice.

Most i do not mind at all, to much information so they are not sure what is important and what not...
But, rarely, in comes the "Smartest human that ever existed" trying to play smart by omitting info at all cost convinced they discovered hot water ... so i press F8
I blame the bloody internet/youtube/anti-social-whatever and normal media/TV/Radio with all the modern sh#t of "inventions" !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Nothing has been invented since Tesla with radio waves and induction motors, so move the f@k on.
Everything else is/are incremental improvements on already existing stuff or new ways of using old stuff.

And do not get me started on "Theoretical Scientists", they do not think they are the smartest living beings, they are CONVINCED that they are! With years i have gathered so much intolerance for them that it is very hard to put on words...

I also blame us, we the normal guys who spent our lives learning and working, for keeping quiet, i know i did till a few years back.
We need to do more on these "social ####" , but we are busy actually doing something.
I have to stop...

What GUI?

Nice find and to damn cheap, you lucky b....
Good luck with the retrofit, there are several similar machine logs here in case you did not see them, but i think all use Mesa controllers with normal servo drives, normal as in not EtherCAT. Some use the old existing drives, IIRC

That's best part about the Flex GUI you can put what YOU want/need in the GUI. I would think you can build the GUI you want in just a few minutes. BTW, there is a series of videos on Flex GUI. www.youtube.com/@Gnipsel/playlists

Yes, parallel port works for that, normally it has only 5 inputs but it can be st to "input" mode giving you 13 inputs and 4 outputs.
There are also some Arduino projects around here, but i never used them.

Probably Nema 34 as machine is old and requires a lot of torque to move.
