Voltage divider for Mesa THCAD-10?

Can you post your hal/ini files?
 

Yes of course thank you so much for your help!

see attached 

The main hal file: plasma_v2.hal
has not been attached.

Hmm that's odd ; I uploaded it but it seems it didn't load or attached, apologizes hopefully this time it works .

OK the reason for the stepgen instability is the the P terms are all set to 10000
but should be 1000 for a 1 ms servo thread.

Great news! It works now!, that P value was definitely the issue. I set my P value to 1000 as advised and the machine operate perfectly now!,

Is the P value something i calculate based on my jitter servo value or is that just a fixed value of 1000? 

For example, if my servo thread jitter reads 15586, would that mean my P term should be 15.586? (15586 divided by 1000?) 


I appreciate all you guys help so much , you are amazing and i apologize for being a noob. I'm doing my best to learn and im getting better everyday, thank you all so much!

Now i have to get a few things polished up and tune it all in. I am so excited!!

I'd love to know why the PNFconfig generates that as the P value? All the DIY's i followed never mentioned that P value was something i had to modify/tune.

Pncconf initially sets the P value for stepgens to 1/servo_period in seconds
(so 1000 for a 1 ms servo thread)

The physical meaning of this is that any position error (due to differences
between LinuxCNCs and the FPGA card clock, jitter, and the time
between reading the stepgen position and updating the velocity register)
is corrected by the next thread invocation.

A P value higher than 1/servo_period will overcorrect, and a a value higher
than 2/servo_period will result in oscillations.
