Activate the

and change it to servo-thread
That should do it.

super. linuxcnc is accepting it.

i did the halcmd show pin and param again for pwm. see file.

now how do i know which physical pin i have to use on the mesa for this?

Might be better to wait fro PCW to answer that.
IIRC, it should be on step/dir pins for the 5'th stepgen, but i might be mistaken.

You do not want to loadrt pwmgen at all, because you are going to be using the hardware pwmgen, not a software pwmgen

At the minimum you need these setup changes

#load pwmgen for run pwm delete
loadrt pwmgen output_type=0 delete
addf pwmgen.update servo-thread delete
#addf pwmgen.make-pulses base-thread delete

setp pwmgen.0.pwm-freq 500.0 change to
setp hm2_7i76e.0.pwm_frequency 10000

setp pwmgen.0.scale 100.0 change to
setp hm2_7i76e.0.pwmgen.00.scale 100

setp pwmgen.0.offset 0.0 delete

add
setp hm2_7i76e.0.pwmgen.00.output_mode 2 (this is up/down mode)


And then the connection changes:

net Xen => pwmgen.0.enable change to
net Xen => hm2_7i76e.0.pwmgen.00.enable

net pwmgen_value pwmgen.0.value <= emcochanger.setpwm change to
net pwmgen_value hm2_7i76e.0.pwmgen.00.enable <= emcochanger.setpwm


net pwmgen_out pwmgen.0.pwm => hm2_7i76e.0.7i76.0.0.output-01 delete

i get the error: hm2_7i76e.0.pwm_frequency does not exist

what does hm2_7i76e.0.pwmgen.00.enable meen? lets say that i want to use the 4th (step dir 3) in row of the stepper terminal screws?

what about:
sig-forward emcochanger.forward ==> ?
in1 goes to 3 dir +
in2 goed to 3 step +
?

and the pwm pin of the ln298n module? apply 5v?

This likely means you are not using the correct firmware or do no have the hardware pwmgen enabled

You cannot, the PWM outputs replace stepgen 4 on the firmware i supplied

what about:
sig-forward emcochanger.forward ==> ?
in1 goes to 3 dir +
in2 goed to 3 step +

Not sure but with the hardware PWMgen set to up down mode
you will get PWM on Step4 Step in one direction and Step4 DIr in the other direction

and the pwm pin of the ln298n module? apply 5v?

Here are the 7i76e PWM related pin and parameter names I get:via halcmd

I did have to change the search for pwm to pwmgen since halcmds
wildcard search apparently does not work with partial words

I see.

i thought i had the right one.

i installed 7i76e_7i76x1D.bit.
i cannot find the 7i76e_7i76x1pD.bit you mentioned,

i did find 7i76e_7i76x1_PktD.bit though

its in the current 7i80.zip file:

this part is DONE.

hm2_7i76e.0.pwm_frequency stil does not exist.

So,
i changed:

to

Its accepting it.

now.

parameter or pin hm2_7i76e.0.pwmgen.00.output_mode 2 not found.

also hm2_7i76e.0.pwmgen.00.output-type does not work here.

see more in Hal file

Did you look at the pin and parameter list from my previous post?
That has the correct names

(its much easier to list the actual names and copy/paste them into the hal file rather than attempt to type them in correctly)
