Thanks very much Tommy.

I'm so hopeless when it comes to the backstage programming stuff I figure I'd better help out where I can.

How can i use PKTUART with 7i80hd?
Include smartserial funtion in bitfile and use a ttl to rs485 converter module?

I think this is long overdue:
Spumco, thank you for all the help you dispense on this forum, and especially, thank you for putting me to shame every time you reply with your very organized and well formatted replies. Not an easy task given the editor is fuzzy.
Some examples of replies:

So I was able to double check for short/faulty cables on P1. I've disconnect the encoder connector from 7i96s and no contact to GND.
Made the change of the location of the THCAD board to the outside of the plasma source in a plastic box.
Connected the shield only on the 7i96s side in the pin TB2.9 with the GND cable.
When I turn on QTPlasmaC the value of Arc Voltage is 145.
The encoder velocity pin seems to be working fine on halshow.

What you recommend to do?

Thanks in advance, really don't understand what's happening.

Glad you got it working, but i have to ask, why python?

Sounds like stepper resonance to me.

Without knowing anything about your drives, motors, or mechanical components... an easy test would be to increase the drive's microsteps and adjust the STEP_SCALE accordingly.

Your STEP_SCALE for X&Y is ~14, and Z is ~20.  This seems extremely low for a typical 5mm or even 10mm pitch ballscrew assembly with 1.8 degree steppers.  Maybe I'm missing something.

You did mention that you've adjusted the drives microsteps, but have you tried all (or some) available microstep values?  What value(s) do you have the drives set to now?

@Morley,

Or just incorporate their better planner into linuxcnc,
I have looked at this. The way lcnc uses it's planner is far of path pilot uses it's planner.
And this seems not to be their latest planner. So integrating is not easy as my first attempt failed.

We have already a new planner wich is tested. It's also tested on plasmac yesterday by Joco,
but that test was not showing the probe sequence. So i have to look at that soon. As i am working
on a different subject now.

I'm facing an issue with my Z-axis linear guide, and I could use some advice.The axis is mounted upright, and I’ve noticed significant vibrations. At higher speeds (10,000 mm/min), the vibrations are less pronounced, but at lower speeds (3,000 mm/min), they are much more noticeable. Interestingly, the issue becomes more severe when the block on the linear guide moves farther away from its mechanical fixing point.I’ve already tried changing the motor stepping settings, but it hasn’t resolved the problem.If anyone has experienced a similar issue or has suggestions for troubleshooting, I’d greatly appreciate your input.Thank you in advance!
Ini for reference.

Cant do this anymore bye all wrote:

Does this patch allow you to select fully preemptible kernel, when configuring the kernel ?

From my experience building with the mainline rt "patch" it was required to edit kconfig under arch. Otherwise there were only 3 options for RT kernel, which didn't include the fully preemptible option.
 

From 6.12 you don't need to apply a patch to build fully preemptible anymore. The patch only puts pack the indicator "/sys/kernel/realtime" which LinuxCNC checks to see if the kernel is real time. It might be that you need to enable EXPERT in the menuconfig to make the fully preemptible option visible, but no need to edit the kconfig

You should change glade file:
github.com/LinuxCNC/linuxcnc/blob/master...ccapy/gmoccapy.glade
in glade editor.

Or you can use:
User Command File
linuxcnc.org/docs/stable/html/gui/gmocca...l#_user_command_file

I was able to get the drive to go into OP mode thanks to your XML file after I changed the PID to my driver.

Thanks again!

我修改了 GMCPCAPY 接口以适应 2K 显示器。我更改了大部分图标大小，但我无法更改这几个图标大小。谁能帮我

Thanks for the idea, but I don't know python well enough yet. I think this function should work by default. And it works if I use Ladder. Maybe someone already knows how it should work. Maybe I need to make some more connections in the HAL file. I have no ideas yet. The error makes a reference to the text in the stdglue.py file. Maybe it needs to be edited, but I don't know how to do it yet.

onceloved, I have tried that with no luck. For the sync0Cycle I've tried the following values with the following servo cycle times:

Servo: 1ms -> sync0Cycle: *1, *2, 1000000, 500000
Servo: 500us-> sync0Cycle: *1, *2

tpa58, thank you a bunch! I'll start with your XML file and see how far I get today then report back.
