If you want to change the function then you would need to make the appropriate HAL connections as well.

Guys? Have You solved the problem ? I wants to use them too but i'm stuck with the settings.

is that a following error?

If so that may be expected before tuning or even determining
if the feedback is in the proper direction. (expect runaways!)

You likely need to widen the following error limits in any case

sorry,
here they say that the drivers are OP and the engines move,
you're on the right track then

Progress on the design. Refinements, Tweaks. I got some quotes from JLC for machining and it might be viable to make these for people one at a time, complete with bead blasted anodised finishing. Frame kit with screws and rails, but nothing electrical. Need to get all the prices to the penny and then I will see if one adventurous person would like one.

 

No compiling.
if using the LinuxCNC official ISO, the only things you have to do is as stated in the linked page
sudo apt update
sudo apt install linuxcnc
it will install everything needed.
It might also complain it need to remove LinuxCNC-uspace, so if it does not remove it by itself
sudo apt purge linuxcnc-uspace
After reboot
uname -a
to check the kernel, and if it is the RT-preempt one, reboot and hold down the shift key till you see the grub menu, there choose the RTAI kernel and press enter.

You should have a flashing red init light when in
fallback mode (IP address jumpers = up/up)
If not, there would seem to be a hardware or corrupted
flash memory issue, or perhaps a marginal 5V power issue

I'm not sure how that could happen. There were no other devices plugged in and even then the UUID the Alert is saying does not exist is exactly the Debian root partition of the SSD.

Yes, I did see that part of the docs. However, that only covers installing LinuxCNC (the software, not the distro) on an already patched to RTAI kernel on a vanilla Debian install, correct? I am still stuck on the part where you actually compile the RTAI kernel and boot to it.

Now that I think about it, while installing the compiled kernel with "make install," I did see some warning about some modules not being found and now the error at boot suggests the same.

I set jumpers w17 and w18 to the up up position, powered up the board and no red flashing lights. Connected the Ethernet port to my home wifi router via cable. I can ping the router at 192.168.1.1. The board should be at 192.168.1.121. But pinging 192.168.1.121 fails and MesaCT can't find the board. These were the same configuration I used when I powered up the board for the first time.

What do you think? Comms on the board is the problem?

Thank you
Do you have any examples of how to move and scale the feedback?
I'm trying to use the 7i77 analog port but it displays an error message calculating movement on axis 2 (Z). Could this error be the reason for moving and scaling the feedback?
Please, where can I find examples of this?
Please tell me the reason for the error below?movement calculation error on axis 2 ( Z )

Thanks for the info. I haven't tried 2.9, only master.

okay
