If U33 is bad, that's a sign that there a problem with the 5V supply
(possible transient overvoltage) I doubt that the 24V supply is an issue.

this waveshare thing working fine with vivado:
www.amazon.de/dp/B00KM70UFG?ref=ppx_yo2ov_dt_b_fed_asin_title

if you only need to load the bitfile, you can use the installed linux-system.

i know that someone in this forum has running linuxcnc on an raspberry-zero 2 with sdl gui,
this is not so fare away from this cores.

## I actually like vivado. wouldn't it be nice to have cnc modules (step gens, counters, pwm etc) set as ip blocks in vivado so it can be just visual drug and drop to create configuration you need. File Attachment:

hmmm, maybe we can convert some rio plugins into vivado blocks
at the moment the complete rio part is shown as one block in vivado.

Ok. Will try that. Thanks
Would powering the mesa board from an external source for both 5v and 24v and isolating it from the esab power supply a good option to prevent this type of issues?

wow, you made so much progress compared to me! i only managed to boot it and connect to it using ethernet to check that its working. it came with crypto software installed which has web server and dhcp configured so i managed to connect to it via browser using ip address.  
now i am waiting for proper jtag that recognized by vivado to start playing with it. 
i too thought about potentially running linuxcnc on zynq but i suspect those cores are just too slow at 600mhz.

There is no existing VFD. The spindle motor is a large, old 3-phase induction motor, and it’s currently started using a classic star/delta starter.

The actual spindle speed is controlled by changing gears in the mechanical gearbox. There’s no electronic control involved right now.

I plan to keep the gearbox, but replace the starter with a modern VFD. That way, I can at least get rough electronic speed control, without trying to replace the entire spindle drive system on such an old machine.

I tried setting up extra joints but am struggling to run them in gcode with custom M codes. Does anyone know the best way to do this? Just need to home and move into position.

I wanted to add that my machine also has a parallel port available, if that would help

Hi Everyone, 

I am new here and new to CNC, Linux and Mesa boards, so pls excuse the novice questions.

This is my setup
I have a 5-axis milling machine, which uses 2 stepper motors for the z axis, so in total there are 6 stepper motors. I have also bought a servo motor ECMA-C21020RS from Delta to power my spindle. I have a Mesa 7i96s card

Now for my question
Have I bought the wrong Mesa card for my requirement? From my understanding, the 7i96s can only control 5 motors so my 6 steppers and servo exceed the capacity. If so, what would be the best solution? To buy another card and scrap the 7i96 or is there an option to buy an add-on card to work with the 7i96s?

Thank you in advance for your help

Hi Everyone,

First of all, thank you in advance for your help. I should mention I am new to Linux, new to CNC, and new to Mesa cards. I have been following the tutorial for getting started with the Mesa 7i96s by talla83 en, but I have been stuck for the last couple of days trying to get the Mesa card found using the Mesaflash command but it always says No 7i96s found. I have tried following tutorials for changing the local IP address, thinking there is a conflict as well as changing the jumper on the card to change the IP address but neither have worked. I wanted to put up my settings here hoping one of you will notice a glaring mistake I have made and could point it out. Thanks once again

I've been playing with the WLED plugin, got a string of 5 led's working for various things, that is really cool.

I thought I'd try add a blink function to one of them. I see that only the WLED_Expansion allows me to assign an LED from another plugin, but when I try I get the compile error

Procedural assignment to a non register "LED_BLUE" is not permitted.

Any idea what I'm doing wrong

pulse width was already 100,000 ns so that wasn’t the issue.

Was that "base-period" ?
Pulse width is 5000 by default, base period is 100000 by default, if not set otherwise, but base period is only present when you select using a parallel port, and this might have been the issue with stepgen numbering etc...

I would use pncconf  (the new one in the link) or MesaCT
and avoid AI as it's really just a time sink here.

I have never seen a missing module in 2.9.4

( There is no motion.so in LinuxCNC so don't take bad advice from AI )

Every other option is going to require you to do some wiring.

Even something such as this, github.com/clough42/electronic-leadscrew, will require you to do some wiring. And this is only a solution to screw cutting and doesn't have any cnc capabilities, tho it doesn't connect to a computer.

Once a again another Electronic Lead Screw, www.rocketronics.de/en/els/ solitaired no connection to a PC,no cnc capabilities but does other some extra features. Is still a user install, so there is wiring involved, but no connection to a PC. not really a budget solution.

First mistake was using a buck conveter, 2nd I would seem to be not checking the operation of the buck converter prior to connecting everything up. 3rd mistake would have been to triple checking everything.

Simple solution would have been to power the breakout board from a known and working 5v supply or whatever voltage the BoB required.
 

Thank you very much for your help.

There is no specific driver for the 7I95T, its supported by LinuxCNCs hm2_eth driver.

Normally you don't need to do anything with the on card firmware unless you have some
specific different I/O requirements. ( Like you want one step/dir output to be PWM/DIR or
you have parallel daughtercard  )

Not sure what explains the initial lack of functioning, possible an issue with the 7I76
config file conversion.
