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...

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.

Look for a 0.25 or 0.34mm^2  ones. I found them on Amazon

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.

Well done, andrax.

There are two homing methods
1. Linuxcnc normal homing. Google "linuxcnc homing" and you will find an article incl illustrative figures describing this. 
2. Ethercat homing. Many people have used it, I have not so can't advise on that.
I propose you start with 1. You can always do 2. later on.
I actually think you are doing 1. and want to use one of the digital inputs as X homing switch. 
The signal you have made looks ok. Just check that din-4 is a general purpose switch, not tied to ethercat homing.
Use the halshow utility to follow/watch pins to make sure they react the way you want.
 

Thank you for the reply. Will try to get something to work. 

Thinking about using Delta C2000 VFD.
