Voltage divider for Mesa THCAD-10?

Unexpected realtime delay on task 0 with period 25597

Is this a parallel port setup? (25597 sounds like a parallel port base thread time)

EDIT I see this is a 7I96S configuration but the 25597 thread period makes no sense
in that setup.

im using a Dell optiplex 780 , What is strange to me is that AXIS works fine on the same exact settings but QTplasma has that error and thus i can't use the THCAD-10 , which was the whole point of me upgrading to the MESA hardware.i did disable dell's performance throttle in the bios and jitter was 15886 , which still didnt alleviate the error on QTplasma when i tried a new PnfConfig..

It is a Mesa 7i96 via ethernet cable, i'm not sure what is consider normal for that value but AXIS worked fine so im confused how it affects QTplasma.

very odd

PCW already mentioned the issue, you have to fix it in your ini file, set the "servo period" to 1000000 ( 1 million), save and start the config again.

I changed the "servo period" to 1000000 and i re-did the config using PNFconfig and the machine moved but the stepper motors just kinda danced back and forth they didnt actually move the gantry at all. 

Any advice on why that is occuring?

My jitter went up a lot for some reason and was measuring 46060 for servo thread and 44293 for base thread.

Do i have a hardware issue with my computer ? I'm reading through the linxcnc documents and QTplasma docx as we speak but it doesnt really dive into some of these issues so im a bit lost on what i can do to resolve this.

I'm sorry to be a burden and i hope it doesnt come off as annoying but im really trying my best here , dedicating hours of trial and error and endless chatgpt questions to learn.

Thank you again everyone for your help, this is my first linuxcnc machine.

I'm genuinely confused how AXIS works perfectly fine and QTplasma doesn't operate as it should, any idea why?
