the fields you don't know are best left on default

perhaps you should organize a
simple/expert option to hide various fields

if someone wants to work on the tooltips, they are a bit scattered in the code.

The setup-gui is generally only in the bin/rio-setup file for now
and a few of the widgets in riocore/widgets.py

You can pass a tooltip to the 'edit_item' function via 'help_text="blaa text"' or the 'var_setup' dictionary contains a 'description' field, in which case this is used.

Yes I am thinking the floating head will be the way to go I was thinking to build it spring loaded or with a adjustable pnumatic spring so that it could be adjusted to cancel out the weight of the torch.

10.5 x 25 cnc plasma table retrofit

Category: Computers and Hardware

Hello I am retrofitting this old mg industries 10.5x25 cnc table. It was previously controlled by burny 10 lcd I am looking to update it to linux cnc. What would be the best direction to go with this? My motors seem to be very old is there any chance of reusing them or is it not worth the effort? I included photos of the motors below and the gear boxes they are tied to.

6i25 with bob. Spindel start/stop

Category: Basic Configuration

The BOB in the picture (blue card) should have 0-10V output for spindle, so you might want to try configuring that, but it does require another 12V power supply.
You should double check this as i never used that type of BOB, and in general i do not use BOB's.

Voltage divider for Mesa THCAD-10?

P value for stepper systems should never be changed, and it depends only on servo period timing, so for a servo period of 1000000 (1 million) it always should be 1000.
Servo period should also never be changed, except in some situations, like when using torque mode servo systems that benefit from faster iteration, or when using a PC with very bad latency. And whenever servo period is changed, so should the PID values.
The math there is 1/servo period in nano seconds, so for
1000000 servo period = 1000 P value
500000 servo period = 2000 P value
2000000 servo period = 500 P value
That is all for steppers in position mode, for servos and steppers with encoder feedback to LinuxCNC those values must be tuned.

Voltage divider for Mesa THCAD-10?

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.

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.

Hmmm that's a weird one.

At a guess it could be a local hardware issue that manifested itself when you made the changes. As this is a guess I could be wrong.

Many many moons ago I had a PSU fail when I did an upgrade from Win2k to WinXP. I think the gremlins that lived in the PSU thought it would be funny to push the fail button just after I did the upgrade. They seem to like Linux more.

One thing you might try is setting the PID MAX_OUTPUT to say 9.5 (95% of full scale)
As the 7I40 cannot have 100% duty cycle (the high side MOSFET bootstrap
requires a continuous PWM signal)

There's this thing called google, you can look up acronyms and find out what they mean. Or you can read the data sheet applicable to your FPGA.

The ones you mentioned are the easy ones, there's a whole raft of others if you want to start messing around with FPGAs. Which is what you are doing, everytime I start on a project I'll have a look at he datasheets of the components involved.

You really need to have a curious mind once you start going down that rabbit hole.
