Ah using Linux to entirely tune the feedback loop?

I am interested in Ethercat communication, but I am getting slightly cold feet as it appears to be a path far less travelled in this forum.

Am I right in thinking that if you run analog signal and rely on linuxcnc to close the loop, all tuning happens within Linux, as per your link?

No auto tuning through the drives etc?

Thanks tommylight.

yes it works if you use 2 tools one with piercing delay and one with 0 delay.
I'm using the tool from sheetcam (tempoary tool created from file). so i need 2 files or edit the file after pierce and reload.
what I'm thinking is just press a button and make the Pircing delay 0,

Silverdragon is based on gscreen and gtk. When I ported it to Qt, I renamed it QtDragon. I have since created an updated version on github, but it's still QtDragon. I'm not creative enough to come up with a cool new name.

Did you fix the typos in your hal file?

Analog servos? Velocity mode?

If you mean the induction motor, no, no one even tried it before him. He knew his s#it, for sure.
Induction motor has no magnets, no rotor coils, no brushes, yet it works!
It has been the single most important discovery that pushed civilization and the industrial complex forward.

Very impressive. Here I was thinking he just invented Tesla coils!

Upload hal and ini files here so we can have a look.

I refurbished a 30-year-old CNC router machine at my school.

The original drivers were E-waste.

The original motors are great.

The original transformer (that powers the drivers) is also great (though it's terrifyingly powerful).

The original rectifer bridge + capacitor were also E-waste.

But most of the original switches are still good (one switch got welded contacts due to overcurrent).

Mechanical things outlive electrical things.

Yep! I'm keen to reuse the majority of the control contractors, breakers and transformers. I've got the full schematics for the machine, so ideally I would splice the original contractor boards into Linux control. 

Thanks for the input!

Thanks for the tip Langdons!

I'm a little apprehensive about cheap drivers as I've struggled with the manuals and particularly tuning in the past.

How was your experience setting up and tuning the servos?

Surface finish and accuracy are rather important to me on this machine
