Hi,
I am using LinuxCNC for years now and my Hardware is since 2020 stable. My hardware uses a Mesa 5i25 for the main job and an 7i73 as remote with an handwheel.
After upgrading to 2.9.7 ( with PC hdd and OS update) I found that my handwheel is always counting, even when not used. I have the 7i73 on SmartSerial port0 loaded with:
Code:
loadrt hm2_pci config="num_encoders=5 num_pwmgens=1 num_stepgens=4 sserial_port_0=1220"
hm2_5i25.0.7i73.0.0.enc0.count -> is incrementing at max speed right after startup. So I double checked all Hardware even with an oszi, but the electrical signals are OK.
So I tested this code in hal, end replaced the HW Counter with an SW Counter. Then all is working as expected...
Code:
loadrt encoder num_chan=1
addf encoder.update-counters servo-thread
addf encoder.capture-position servo-thread
# HW Count
net 7i73-mpg-count <= hm2_5i25.0.7i73.0.0.enc0.count
net 7i73-mpg-rawcounts <= hm2_5i25.0.7i73.0.0.enc0.rawcounts
# SW Count
net handrad-phase-A hm2_5i25.0.7i73.0.0.input-08 => encoder.0.phase-A
net handrad-phase-B hm2_5i25.0.7i73.0.0.input-09 => encoder.0.phase-B
net 7i73-mpg-count-sw <= encoder.0.counts
# use SW Count
net 7i73-mpg-count-sw => axis.x.jog-counts
net 7i73-mpg-count-sw => axis.y.jog-counts
net 7i73-mpg-count-sw => axis.z.jog-counts
Even when it works now, I would like to understand the reason behind to check if the is the even more trouble, which I didn't find till now.
Question:
Where there relevant changes in hm2? My old LinuxCNC before was 2.8 ....
Is a "Firmware" Update neccesary ?
Could this be an defect inside the 7i73? Is something similar known?
