For the CSP and similar modes generally the target position is fed directly from the joint pos-cmd output, so it does not go through a PID control to account for error like you might see in a velocity control loop with positional feedback.

Message them here lichuanmotor.en.alibaba.com/productgroup...408298/EtherCAT.html

They shipped DHL and got to me across the Pacific in about 4 days for USD $32

I thought it had already been established that Tormach do not have jerk limiting.
Another possibility would be to run a gcode filter to "normalize" the gcode for performance and jerk limiting. Joco's Monokrom filters out all holes and replaces them with its own optimised code with custom leadins so it can be powerful in the right hands...

We have to get this going as its soo cheap!

I had a Yoga once. I even ran Linux in it. Nice laptop but no wired internet so not suitable for Mesa cards.
Even if it had one, the power savings features and very limited ability to tweak the BIOS would render it unsuitable.
If it had a PCMCIA card ( don't think it does) you might be able to install a PMCIA network adapter

If mesaflash reported that error, update mesaflash
(instructions on the git site or above in this thread)

github.com/LinuxCNC/mesaflash

If LinuxCNC reported the issue, you need t o update LinuxCNC.

(You don't actually have to update LinuxCNC as it will work fine but will complain about the card every time you start LinuxCNC)
 

Whats is your name on the email? (just the name not the full email address)

The 7I96S's are at assembly and should be available in 3-4 weeks

I'm having the exact same problem, has anyone figured out what's going on?

Tks

Sorry its from Lichuan. They also have a closed loop one too

Hi guys. I've spent the morning having a go at getting a 4 axis ethercat drive working.
Just the most basic config I could devise from Dominic's sample.
I got movement from the first drive but its not right. just a whine and a bare stutter.
I wondered if one of the phases was the wrong polarity but no luck with that. The same result which was odd.

There is a windows USB config program which let me set the motor amps to 2 amps and I could see the steps/rev was 10000 which seemed high.
Any ideas would be appreciated. They are a good solution if we can get it going at USD $92 + shipping (for 4 stepper drives - $23 each stepper)

For what it's worth, did you try to connect USB power to both adapters? They appear to have a 'charger port' in the side. I think HDMI can supply some power but it seems quite limited.

a quick follow-up on the E stop. I checked everything on my side that I could think of and the light stays on. I just upgraded from the original PB where the E stop button worked as it should. Maybe I was not clear with my issue. When I activate my e stop on my pendant the screen E stop light goes off. However if i push the screen E stop button the machine stops but the button stays on. You think its still on my side?

To late but would have been better and probably cheaper to get DP-HDMI cable with more length, higher quality one should be 20-30$.
Do not install NVIDIA drivers on a machine PC with RT kernel, it does not work to be happy with it, and sometimes at all.
Now some better news, boot with the add on graphic, wait for it to go blank, wait a bit more, after roughly 2-3 minutes press and hold CTRL+ALT and press several times backspace, this should reset the X server and maybe, just maybe switch to working monitor.
Tip 2: connect another monitor to VGA port, boot Linux, go to prefernces and screen or monitors or displays, there chose and turn on the monitor on WiFi link, apply. If it works, reboot to check if the settings stick.
Tip 3: power on the PC with a working monitor, press or beat the right SHIFT key till you get the GRUB menu, hit E, use arrows to go to line containing "quiet splash" or similar and add after it "nomodeset", press F10 to boot, connect the WiFi monitor and disconnect the working one, wait for it to boot.
If any of those do not work, probably the WiFi dongle does not comply with HDMI standard communication, as i doubt the DP-HDMI adapter is not working, although i have seen DP-HDMI cables failing miserably to work on some PC's while worked fine on some other PC's.
