its a bit involved, you can look here for the basic hal setup

linuxcnc.org/docs/html/examples/mpg.html

(that happens to use a software encoder counter but the basics are the same)

Note that there are jog enable,count and scale pins for both axis and joints
The joint pins are active before homing and the axis pins are active after homing.

You could also search the forum for "MPG" as there may be a MPG setup using similar
hardware as yours.

You have no idea how glad i am, while reading i started thinking i forgot Czech!!!

I have installed Stahwerk plasma, have two more on order for some clients, so no worries about it if he does not reply, there is still hope.
You should start a new topic, though.

hello scotta and thank you for your amazing work
i got my rp 2040 working with remora and its amazing 
it works with axis and qtdragon 
my question now is how to get it to work with qtplasmac, i cant get it to work even though i copied all the necessary config lines in both hal and ini files from my par port configs
can anyone help me with this
Thanks in advance

this isnt necessarily within the scope of remora, but more related to linuxcnc and hal config, but if you used one of the config generators, I would suggest redoing your config for a mesa card, its fairly easy to convert a mesa config to a remora config with minor changes, paraport had more stuff going on last time i looked.

otherwise, it would be helpful if you posted the errors you get when trying to start linuxcnc, these can be easily viewed by opening linuxcnc in terminal. Posting your ini and hal files would also be helpful. there isnt much difference between a plasmac config and any any other config, except there are a few hardcoded hal pins you need to connect to for plasmac.

Bulls eye, Tommy. It's Polish indeed. His nickname suggested me he's polish. i have the same machine (stahlwerk cut 70p) with machine torch sitting in the box for more than one year now (yes, haven't used it yet:D) and i think it's time to have some fun with it. it's HF pilot machine and i'm trying to figure out how to make it usable in cnc table. Have a bunch of Mesa cards i bought some time ago when i was visiting the States and would be nice to make it all work together. i don't have THCAD though...:/

Invert the spindle pin in hal.
something like
setp rpi_pin_number_00 invert true

I want to connect my spindle to a 5 Axis Breakout Board Interface Adapter via a raspberry pi5. I can control the stepper motors (XYZ). I just can't control the spindle. Is there an example for the HAL file?

If I bypass the relay contact. Then the spindle will rotate to the maximum. If I press the + button it slows down. When I press the - button it speeds up. When I press the stop button, it starts running at maximum speed. 
Anyone have a solution?

Greetings Philip

Hello Folks;

System:
Converted knee mill with  old SEM brushed servos running on amc servo drives in openloop mode.
Mesa 6i25 + 7i77
Loop closed with old prototrak  axis scale encoders, not from the motor encoder.

No matter how I try to tune PID & FF, many times the axis moves stop off about .004 sometimes much better.
I have deadband set to 0.
My max feed is 60.0 in/min.
Have tried various accels  now around 30 in/minsq
Most PID seem to have P around 50. No I or D
FF1 from .5 to 2.0 seem to get a reasonable error halscope.
 Just being more than  about a thou off isn't good enough for real milling.
Any info to help or graphs needed just let me know. I have played around with this ever so often for a long time.
But this time, I seriously want to finish this mill
regards,
Jon P.

If the torch is firing on that video, for sure interference.

Set the networking as described in the readme, connect stuff, open the included config folder, right click on the ini file and choose "open with" then linuxcnc.

its not a random config. it is the exact machine i have, i based the purchase of mesa hardware because it has been done and the config exists. if it didn't i would of chosen a masso g3, mach3 or acorn based upgrade.
currently it is just a bare card on the desktop next to the computer, i want to get that end done before i start making the controls box.

I just connected up a MPG type encoder to inputs 0 & 1 on TB-3 of a 7i96s. I can see hm2_7i96s.0.inm.00.enc0-count moving as expected when I rotate the MPG.

So now how would I go about getting that count to actually move the Z axis?

Worth noting that I also have a functioning pair of jog buttons, I envision using either method (buttons or MPG) to move the axis manually)

Thanks

No idea, i built a NAS last year, so i can not recal if i moved the files there from the phone.
If i do find them, i will let you know.

Been 20 years since i was in Czech Republic, but that seems more like Polish! Or Slovak, maybe?

Hey all I care about is I see that count when compiling kernels and things ... rather quickly,.....

Oh hell, i just got a 14400!
It shows 16 cores! yeah riteeeeee.
No time to mess with it till tomorrow, i might do some tests and see if i can disable the economy cores and how much impact it has on performance.
And yes i know, but i am not calling them efficient cores, they use to much power to warrant that name, and they do not much work.
