Plasma and Ethercat?

Category: Plasma & Laser

The ”whole” idea is to stabileze the molten hafnium, tungsten or whatever the electrode material is.

Hafnium does not melt, it erodes.
Would not be much use molten, and to get it to melt, the surrounding copper electrode would have melted loooooong before hafnium.

PCW is trying to explain the induction phenomena that happens when applying voltage to a coil and then cutting it, the coil will induce current on it's own.
Find an electromagnet, apply some voltage to it and cut the voltage while watching the scope, it is amazing what voltages can be produced by it, way beyond what has been applied.

Sorry not sure what you mean, but when the arc is turned on or off its done in a controlled way. The ”whole” idea is to stabileze the molten hafnium, tungsten or whatever the electrode material is.

I think we are tallking about different things, sorry about that.

Hi kworm !
Everything has been good with the drive, tuning and movements through the drive have worked without issue.
i had to config the PDO's also so that all appeared to work...

using the Leadshine motion studio software
I do see the Control Word = 0x0
and the Status Word is 0x410 so it looks like the LinuxCNC EtherCAT Master is not trying to put the drive into operational ?

Looking for one or the other.   Trying to update a Tormach machine and was a little disappointed to learn that the 7i92th is not a direct replacement for the earlier cards. 

Will purchase, or if you can use an 7i92th, I'll trade for one of the earlier versions!

So it looks like the Pi OS can see that port, (Bus 002 Device 001)
That is the HUB inside the PC/RPI, there is nothing that can be touch related there.
Some of my laptops show "Wacom Co. LTD" as they have touch and pen.

Your mappings look ok. I'm not familiar with Leadshine drives but have you tried the drive software? If you can connect it while LinuxCNC is going you may be able to see what is preventing it from going OP. You could also use the software without LinuxCNC running and make sure you can get motion.

Just fixed an obvious mistake
net x-statusword lcec.0.0.cia-statusword => cia402.0.statusword

all changed to reflect number idx= 4 from .xml
like the below
net x-statusword lcec.0.4.cia-statusword => cia402.0.statusword

LinuxCNC is now opening but the drive is still in Pre-Operational and not moving the motor.

Didn't know those existed...
Interestingly yes the SIM ran up no problem.
For those looking for the sim files, they live in :
/usr/share/doc/linuxcnc/examples/sample-configs/sim/touchy
Now, I need to think about why that worked....

Kworm : i think i have the pdo's right in the drive Vs the terminal output Vs the .xml ? please let me know if i am not understanding correctly. Thank you for your time.

i have been reading and come across a post about a Youtuber called Marco Reps ? i thought it would be a idea to apply some of the methods i found in these files. so i have changed things from my first post, and i am now getting errors again / LinuxCNC is not opening.  this looks to be the main issue ?  EL8_machine.hal:41: Pin 'lcec.0.0.cia-statusword' does not exist

Alright, I assumed you would have one since you have an rpi image builder. But likely it uses a prebuild from Debian that seems to be patched already.
