Hi Rod,
If you take a closer look, i use a ribbon cable to attache it to the PCB, no wiring required at all (just ethernet cable for io keys and usb cable for keyboard part and 24vdc power cable, of course)

Regards

Like in the hal file do I just add:

loadrt pwmgen output_type=0
addf pwmgen.update servo-thread
addf pwmgen.make-pulses base-thread
net spindle-speed-cmd motion.spindle-speed-out => pwmgen.0.value
net spindle-on motion.spindle-on => pwmgen.0.enable
net spindle-pwm pwmgen.0.pwm => parport.0.pin-02-out
# Set the spindle's top speed in RPM
setp pwmgen.0.scale 1800


And

loadrt pwmgen output_type=0
addf pwmgen.update servo-thread
addf pwmgen.make-pulses base-thread
net spindle-speed-cmd motion.spindle-speed-out => pwmgen.0.value
net spindle-on motion.spindle-on => pwmgen.0.enable
net spindle-pwm pwmgen.0.pwm => parport.0.pin-03-out
# Set the spindle's top speed in RPM
setp pwmgen.0.scale 1800

Hi so my machine uses a parallel port and the spindle speed can apparently be controlled by PWM.  The thing is that there’s only two pins for the spindle control, pin 2 and pin 3.  In my user manual it says pin 2 is Spindle-CW and pin 3 is Spindle-CCW.  Does this mean that the PWM signal also needs to be set to those same pins?  I’m looking at the instructions for PWM spindle speed here  and but don’t understand what I’m supposed to do?  Do I just follow the directions but set the pins to be those same pins 2 and 3 in the hal file?  Thanks

Probably should say 2.9 instead of Master somewhere.
Sorry for the vague reply but was long ago.

You are welcomed always.

Thanks for the answer, I understand how the limit3 component works, what I don't understand is how to configure the physical maximum/minimum and homing limit switches without going through the motion controller, that is, signals like:
joint.N.home-sw-in
joint.N.neg-lim-sw-in
joint.N.pos-lim-sw-in
They lie in motion control and would not be available if you were not using the motion controller.

Don't hesitate to correct me if I'm wrong Aciera, hehe, thanks, I'm waiting for a response.

Greetings to all.

Fantastic. I will incorporate the changes into 2.9.3. Thanks for sticking with it.

Please update in the future how you find the z level compensation works for you o your project.

I cloned what I though was 2.9.2 but VERSION says 2.10.0-pre0. It works but should I go back to 2.9.2 which is supposed to be stable. How do I get that version? Is there a branch name for it?

Many thanks for the quick reply.
1st job after we've eaten !

Broken pipe is a python error, i think, so has nothing to do with parallel port.
Set it to EPP and 0x378.
Got through stepconfig, enter values as correctly as you can, save the config, start said config and test the machine.
Use the Calibration from the Machine menu to tweak and tune the scale till you get precise distance traveled.

Copy the configs directory to a USB stick, if there are no special components made by you in use, that is all you need.
Ubuntu does not use RT kernels anymore (no idea why), but you can safely use Debian RT kernels in Ubuntu, i know it worked for sure with 6.1 i think.
Edit:
got reminded below by PhillC about why Ubuntu has not RT kernel, they do but it is behind a paywall!

My condolences.

I've just had a brain wave - checked the parport mode in the bios, and discovered the default setting for this pc is PS/2.
Now faced with decision - EPP or ECP ?
EPP gives 2 addresses - 378h or 278h ?
ECP gives 3 addresses - 378h, 278h and 3BCh.
In addition, ECP then offers a DMA channel setting - OFF, DMA1 or DMA3

Feel I've opened a can of worms, but may be on the right track !
John

EDIT I've tried EPP with both addresses, but in both case I get the 'Error - broken pipe' pop up.

I think Rod mentioned a while back some google video about it, had a look at it, it was good so i saved it somewhere... no idea where, i'll have a look later and post back if i can find it.
Not sure if it was C++ but those are quite similar.
