Thanks for checking things over PCW!

I can't setp the value since it's linked to a signal, but when gcode runs M67 E0 Q0, GPIO 017 does go false.

'setp hm2_7i76e.0.pwmgen.00.scale 100' has been added, this may yield better results. Since I didn't set the scale, all values (1-100) were sending full power. This tip right here may be the biggest sanity check, thanks PCW!

The connections look OK

If you set the PWM value to 0, does GPI0 017 go false?

I don't see that the PWM scale was set so anything >= 1 will be full scale
(default PWM scaling is 1.00 = full scale)

If the PWM values are in percent, you probably wantsetp hm2_7i76e.0.pwmgen.00.scale 100

in the hal file



 

Use Rufus to write the ISO to USB, or Balena Etcher should also work.
Also make sure the BIOS is set to boot from USB first, or, press repeatedly the F12 button at power on till you see the bootable device list. F11 on some PC's, F8 on Asus, etc.

You can wire the drives directly to Mesa and get rid of the parallel port boards.

pushed the 'last run line' log - see what you think.

I've got to get better at asking the right questions... Using the old config:

signal 'sj'
motion.analog-out-00, and
hm2_7i76e.0.pwmgen.00.value

All these values update as M67 changes the output.

hm2_7i76e.0.gpio.017.in toggles to True when the gcode starts running.

Does everything seem mapped right for the PWM to reach pin 1 on a 5 axis breakout board? Should that be on hm2_7i76e.0.gpio.017.in? Maybe the code is fine, and I should be chasing down a hardware issue?

I did find a USB Stick with a full back up set of files. I know the hardware must be fine , I transplanted the computer from the other mill. It would make the steppers at least jump. The computer would not even boot from the ISO so I could reload the OS.

I wondered if you posted the wrong file
I fixed the screenoption colors and axis button LED color on 4th and 5th axis?
I could not get those tool buttons be the same size - ran out of patients!

I agree with Tommy, the one on the right.

Almost got the last line number request done...

See the pinned topics at the top of the page, especially the Remora with SPI as it uses 3d printer boards.
See also other topics there, might be something you can find in Turkey.

Hello,
I just joined the forum since I'm making good progress with my PRINTNC project. I want to use 4 closed loop step motors (2 steppers for z axis). I keep look around but everyone is using a MESA boards or a raspberry pis with some kind of adapter boards for connecting the stepper drivers.

  I live in Turkey and I can't get anything through customs that's over 30 Euros I can't get the MESAs or the adapter boards for raspberry pis (No shipping to Turkey). BUT I have access to 3D printer control boards. like BTT Manta M8P and MKS SKIPR V1 or MKS Tinybee. Is something possible with these?

I would be very glad if you can point me in some direction. Thank you.

If you don't want to use your old config, you could simply copy all the
lines from the old hal file that contain 'pwm' and import them into your
new hal file.

My suggestion is to use:

www.diffchecker.com/

I tested by cutting/pasting your previous and new files; it shows the difference and it gives you the ability to merge the differences line by line.

Hi I can give this a try with BIGTREETECH Manta M8P and closed loop stepper motors and drivers. If you can help me with the wiring and everything.
