Problems with Lichuan Ethercat servo drive

Category: EtherCAT

They do seem to work. I've spent about 3 hrs tuning these so far. I'll have a hopefully final go next week. I've got 4 1kw servos (gantry). There are enough details in the manual to do the tuning. The velocity feed forward from Linux Cnc really helps with following error to a ramp, which is what I'm testing. I wish there was a way to restart communication without restarting the drives. It is tedious using the buttons on the drives. If I get a satisfactory procedure I'll write it up.

Built In Wifi Not Working Raspberry Pi 5 and 2.9.4

Category: General LinuxCNC Questions

I don't know where you saw the info about the setup wizard, but this is absolutely wrong.
As the image is essentially Debian Bookworm you can use the below link to get an idea. Also there is a large sticky thread related to the RPi images, in the Installing Linuxcnc heading.
What other image are you referring to ?

I'm still waiting to see these in proper functional use on a machine too.
These are very appealing to spec on my machine, but I want someone else to make sure it works first, hahaha.

Thanks for your reply! If possible can you share exact settings so that noobs like us can know and get this 7i95t up and running. Any help will be highly appreciated.

Custom Panel was created by noqui

Custom Panel

Category: AXIS

Hi. I am a little bit confuse about working with your own Panels.
I modified the AXIS.ui with this panel ROBOT.ui

Se image 1. ROBOTui

Basically, I only added 6 tab windows

Then, as in the documentary PyVCP says it must be included in the INI I did it.
See image 2 PyVCP

But when I run again the Linux Stepconf to include the changes I find a place where I should add custom panels.
See image 3      Stepconf


In conclusion I don´t know where I have to place my custom ROBOT.ui that is an AXIS.ui modified.

Sorry for my English, is not my mother tongue,
By the way I am working in the translation into Spanish of the Developers Manual - 25 January 2025.

Thanks a lot.

Should I just suck it up and buy a good stepper driver?

Category: Driver Boards

I have seen plenty of dead drives due to those mosfet drivers, some IR.8.1.2.. i can not recall, but i did not bother to check why or how, just left it to using cheap IRF540 or IRF740 output stages that have max 100V VGS and slapping 80V working voltage on the drives, so any coasting or hard brake would release the magic smoke.
I am sure you can figure out what company made those.
Fortunately i still have some in use as with 30-48V they are fine.
