Loadrt hm2_eth
That should be the line for 7i76E and that line must contain num_pwm = 1.
Do not change other stuff there if you already have a working machine.

num_pwmgens=1

Also the rest of the hal file is setup for a software PWMGen so needs to be changed for the hardware pwmgen

Yes, i got num_pwmgens=1 changded.

My apologize, i don't understand how to change it to hardware pwmgen....

i got some progress though.


#load pwmgen for run pwm
loadrt pwmgen output_type=0
addf pwmgen.update servo-thread
#addf pwmgen.make-pulses base-thread
setp pwmgen.0.pwm-freq 500.0
setp pwmgen.0.scale 100.0
setp pwmgen.0.offset 0.0


loadrt emcochanger
addf emcochanger servo-thread

loadrt timedelay count=1
addf timedelay.0 servo-thread
# will wait 5 secs approx and turn motor off after reversing against stop
setp timedelay.0.on-delay 2

net tool-change iocontrol.0.tool-change => emcochanger.toolchange
net tool-changed iocontrol.0.tool-changed <= emcochanger.toolchanged
net tool-number iocontrol.0.tool-prep-number => emcochanger.toolnumber
net tool-oldnumber iocontrol.0.tool-number => emcochanger.currenttoolnumber
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared

net sig1 emcochanger.opto1 <= hm2_7i76e.0.7i76.0.0.input-21
net sig2 emcochanger.opto2 <= hm2_7i76e.0.7i76.0.0.input-22
net sig3 emcochanger.opto3 <= hm2_7i76e.0.7i76.0.0.input-23
net sig4 emcochanger.opto4 <= hm2_7i76e.0.7i76.0.0.input-24


net sig-forward emcochanger.forward => hm2_7i76e.0.7i76.0.0.input-00

net Xen => pwmgen.0.enable
net pwmgen_value pwmgen.0.value <= emcochanger.setpwm
net pwmgen_out pwmgen.0.pwm => hm2_7i76e.0.7i76.0.0.input-01


net xhomed axis.0.homed => emcochanger.ishomedX
net zhomed axis.2.homed => emcochanger.ishomedZ

net delaystart timedelay.0.in <= emcochanger.delaystart
net delaydone timedelay.0.out => emcochanger.delaydone

Linuxcnc starts!
The encoder giving signals to the input pins! :cheer:

So, hm2_7i76e.0.7i76.0.0.input-01 and 00 isnt right one for this of course.

could you show me how to wire and what to change?

First delete or commnt out all lines in the hal file that have "pwm" in them
(except the num_pwmgens )
This is because those lines make sense only for software PWM

Then after you launch linuxcnc, list the available PWM pins and parameters
by typing this in a terminal:

halcmd show pin *pwm* (for pins)
and
halcmd show param *pwm*

okey. i have done that.

in the terminal i saw at pin:

emcochanger.setpwm

owner= 46
type=float
DIR=out
Value=100


at show param *pwm* Nothing

You should have at least seen num_pwmgens=1
Is that still there in the loadrt-hm2_eth line?

Please attach the ini and hal files you are using.

here are the hal and ini files as requested.

if i only comment out two lines i got more parameter . but no num_pwmgen=1

i also found out that one of the four sensors are defected.
so i have to find a new IR photointerruptor. :dry:

encoder is working again.

so, what am i doing wrong in the hal file?

Change num_stepgens to 4.
Activate the
#addf pwmgen.make-pulses base-thread
and change it to servo-thread
That should do it.
