I had a look at the engineering required. Metric engineering by a US engineer associate so you will have to live with it.
As per the Work energy method, www.machinedesign.com/motors-drives/arti...rs-for-linear-motion
3 sec cut 1% Accelleration profile (eg. accelerate to cut speed in 30 milliseconds)
500lb gantry (227kg) 3000 rpm motor with 33.9:1 reduction per photos and a 60mm diameter pinion, gives you almost 18m/min rapids (about 700 in/min)

At a maximum design cut speed of 10240 mm/min (403 inch/min) Check your cut charts and advise.
Peak torque 38.8 Nm
Peak Power  342.6 Watts
Design Accelleration 5.68 mm/sec/sec (0.58 G's)
this indicates a 400W motor would suffice. Allowing 50% threshold, select a 600 W motor

 Changing the gearbox  to 18:1 would increase rapids to 32 m/min or 1260ipm

Even if that is the case, the firmware sources should be supplied, if in fact the firmware is built from Mesa's sources.
There is also the thing about portraying as a 7i92, which in fact it is not.
I have a feeling that some of these boards are being built from the reverse engineering YouTube user talla83 has done.
However it happens what it comes down to is, do you want a product from a well established company with a well established support network, or some entity that is using some else's IP and with no established history of support, and in fact the original company, Mesa, is supplying the real support.

I've been trying to avoid these useless headbutting exercises, but I feel like some things really need mentioning.
What is also a little ironic is that Mesa will supply schematics when asked, yet I wonder how many of these manufacturers would extend the same courtesy ?

I have communicated with the seller, and they replied that the board comes with a pre-installed custom firmware. There is no need to flash the firmware. Once you receive the board, you can simply use PNCconf, enable the advanced options, and directly read the board’s I/O for configuration

I got my chance to look at the motors on that Messer plasma table I had mentioned. It has Bosch Rexroth Indramat servo motors:

The X, X-slave, and Y axis each have a MSK050B-0600-NN-M1-UG0-NNNN which is a 600 watt motor.

The Z axis (torch lifter) has a MSM031C0300-NN-M5-MH1 which is a 300 watt motor.

I forgot to look at the planetary gearboxes, I now wonder what gear ratio they are.

These Rexroth seem to be pricey motors. I have very little experience with the really cheap servo motors but my experience with other cheap industrial electronics has been that they are generally built lighter than their more expensive counterparts (not always). With the cheap stuff I try to oversize some to compensate. Considering that, I suggest 1000 watt cheap servos, but it's your call.

If you could provide me the weight (mass) of the gantry plus that of the equipment that will be attached to it, and also the friction of the gantry, I can estimate the speeds and accelerations you can expect from these motors.

I would suggest measuring the rolling friction with a scales, maybe something as simple as shoving the gantry about by pushing a... bathroom scale against it.
 
Tell me whether you are interested in my method of helping. I will now stop making noise here until I hear from you. 

Just bumped into this:

See description for code.

They should provide the firmware source files as well. Especially the ucf file if it's required you need to modify the firmware. Or otherwise you'll need to perform a boundary scan to work out what FPGA pin does what. One can not be sure if they have followed the same same pin assignments as the Meas schematics. These could change for simpler PCB routing.

Still wondering...

ooops, quoting wrong post, Or did I think you were a noob?

Trying to repower some machines. Want to use a control board with integrated stepper drivers, so it will fit inside the machine. That rules out using the Remora compatible ethernet boards.

There isn't a whole lot of room. Not sure yet if there is room to fit a skr and raspberry pi. Having the raspberry pi inside the machine isn't ideal. Would need a separate pc to use for remote desk toping to it.

Was planning on using an Intel NUC. That's much more powerful than a raspberry pi. Also has a proper enclosure.

Guess if I had to I could mount the raspberry pi on the back of the monitor like I was going to do with the NUC. Then run the spi wires to the machine. Going to need a bulkhead connector anyways. Wouldn't really matter if it's ethernet or a 6 pin connector.

With another machine I used a Genmitsu usb Mach 3 board. It's a compact controller like what I'm looking for. Unfortunately that has been discontinued, so I'm looking for an alternative.

The other option is to use the skr as is, or similar grbl board. The ones for routers are much smaller. Tried Universal Gcode Sender a few years ago and didn't really like it. It worked, but is very limited compared to Linuxcnc or Mach 3.

You can add two lines for upper and lower case each, removes the need to keep track of how it was saved.

Linux file names are case sensitive but Windows filenames are case insensitive. Take the learning as you will need it again!

Yup, should have known better but I've spent too many years in windows world and when I go to do something quick it bites me every single time.
(still getting my feet wet with Linux)

I've got 100 26g on order but I don't like trying to double them over to make it large enough to crimp securely, seem to put a lot of faith in that spot where it comes out of the insulation

For now I'm seriously looking at trying this, actually seems to have a really good grip.. in theory it should have at least a decent electrical contact...

Ferrules come in smaller sizes than the 0.5mm^2 white one.
www.efixx.co.uk/Know%20How/ferrules
Look for a 0.25 or 0.34mm^2  ones. I found them on Amazon 
www.amazon.com.au/Hanibos-Ferrules-Cable...n/dp/B0CHFP7RGC?th=1

I didn't know the smaller sizes were available either!

Never occurred to me that it would be case sensitive.... My Mastercam is set to spits everything out in unppercase including the extension.
Many thanks for making me look at it again.
