etch servo configuration

Category: Basic Configuration

In addition to setting the PWM mode to up/down, you would need to change some names:

ORIGINAL

net Xpwm pwmgen.0.pwm
net Ypwm pwmgen.1.pwm

net Xdir <= pwmgen.0.dir
net Ydir <= pwmgen.1.dir

net Xdir => parport.0.pin-02-out
net Xdir => parport.0.pin-04-out
setp parport.0.pin-04-out-invert TRUE
net Xpwm => parport.0.pin-03-out

net Ydir => parport.0.pin-05-out
net Ydir => parport.0.pin-07-out
setp parport.0.pin-07-out-invert TRUE
net Ypwm => parport.0.pin-06-out

To something like:

net Xup pwmgen.0.up
net Yup pwmgen.1.up

net Xdown <= pwmgen.0.down
net Ydown <= pwmgen.1.down

net Xdown => parport.0.pin-02-out
net Xup => parport.0.pin-03-out

net Ydown => parport.0.pin-05-out
net Yup => parport.0.pin-06-out

Note that you may need to change the sign of the PWM scale or swap the up,down
parallel port pins to get the correct feedback direction.

Translation files for QtPlasmaC

Category: Plasmac

I have only edited the file in LINGUIST, do I need to do this step from howto?
If any text changes are made to the GUI then run the following to create a GUI python file:
$ pyuic5 ../qtplasmac.ui > qtplasmac.py

No, you only need to do that if there are any changes to the original English version so the changes can be added to the translation.

What is the file that you attached, there doesn't seem to be any translations in it.
Can you post the .qm and .ts files as a zip file.

if (when linuxCNC is running) you run

halcmd show all  | grep 7i77

You can get all 7I77 sserial pins and parameters

But setup is kind of strange. For same pc on debian from iso list, i needed to nohz=off and nomideset to get 22-25 delay.and isolcpus=1. Here only the latest one. With two other system is slugish and result is worse. And i have lpt on pcie card. I can see it, but it does not show error if any other adress is beeing used. Normally xe000 is shown in lspci.

Also on i have left speed step on in bios. If turned of - cpus is at 800 mhz all the time. Strange..
