Estop fixed, my mistake.
But as soon as i enable, the servos howl like mad, even though i had just tuned them perfectly. Hmmmmmm.

Have you raised an issue on the LinuxCNC github page?

While I've raised a couple issues in the past, I am reluctant to directly engage on GH because I don't speak 'computer' fluently.  I can describe an issue in laymans terms, but as soon as any discussion moves towards code-type testing & solutions I'm lost.  My typical modus operandi is to prompt enough discussion on this forum that somone clever takes up the torch over on GH.

I'll raise one now, thanks for the reminder about it.

EDIT: github.com/LinuxCNC/linuxcnc/issues/3455

I have no working config.
ill figure it out after lunch.

I just came from a fight with e-stop in a new config with qtdragon, and I didn't win. I'm quite sure I don't have the answers.

If you have a working config, one option is to replace the hal file in that one. Idea is that it overall worked before so it should overall work now.
Another way is to start with the simplest axis interface config from linuxcnc examples, replace the sim* hal files with the cia402.hal file.
 

Hi Halas,

There is added a hal param for inertia wich can be set to from 0 up to 1 to run at programmed feed.
This results in less feed fluctiations at corners.

See the param section :  readme.

Also program execution time should be faster. As i reverted the acc max change.

Hehe that was a joke. Although right now the machine is stuck on estop and I'm not sure why. I'm sure it will be something dumb.

I'm new to this and was asking Chat GPT what the problems were with Lichuan drives. It says EtherCat Master stacks on Linux CNC expect drives to follow CiQ 402 correctly, but Lichuan drives lack full state machine compliance, and incorrectly transition from Ready to Switch ON to Operation Enabled, etc. Windows stacks are more tolerant of violations. So by plugging the drive in after they have done an illegal transition, Linux CNC stacks remain happy.

Thanks for waking me up
It's even worse, not only - and _ got mixed up, it should have been:
net tool-change iocontrol.0.tool-change => sauter.0.toolchange
net tool-changed iocontrol.0.tool-changed => sauter.0.toolchanged
net tool-number iocontrol.0.tool-prep-number => sauter.0.newtoolnumber

Now Linuxcnc at least starts ok again. Let's see if I can get the turret move...

Cabinet almost ready for sand blasting and paint. 

So, change made, AC power component is gone and first small test job ran successfully. Hoping for the best . Thank you again!

 

I’m not sure I’m the winner:))).I hoped to have something more normal than this monster. Anyway when motor or driver will brake I will be forced to replace it.:-??I’m thinking to go with 7i92tm, 7i76, 7i73.My first ideea was to use ethercat but I will use veichi analog servo in the end. I don’t want to make a hibrid system and is my first retrofit.i have also installed a heidenhain ttl 5V on spindle I hope to make it work rigid tapping. I succed to find a plate clean for motor 1:1. This is actual motor

Yes the encoder must be serial, I found these motors for €190 each, I will try to lower the price they are 400 watt battery-powered absolute encoder 131072 pulse... I tried to set it in the drive and it is in the list.

Use it?
Use the hal file from here as starting point to get the servos going.

You have not solved anything. If you want to use cia402 devices and the component, you need to read all at the beginning of the servo thread and write all at the end of it.

My thought is you have blindly copied a config. This is not plug and play, you need to build a config to suite your devices.

Thanks rodw, I had ordered a DM542 from Steppersonline and it arrived today. Even with the 24v and 270OZ stepper and DM542 set at 3A I now have plenty of torque. Problem solved. I guess the TB6600s weren't up to the task.
Great to hear. I really don't know why people ever recommend TB6600's. They have been known to be cr@p for years.

There is more on the table yet! Have a look at the green and red lines here showing the torque difference between 24v and 48v for a 3.2 amp nema 23 stepper

The temperature rise was a max of 60 deg C (40 deg in the graph) so still at a very safe level.
