Can i use 5A Sanyo Denki 60mm stepper motors?
 
Of course you can. Plenty of ethercat stepper drivers out there. even 2,3 and 4 motor controls in the single driver...

links to the multi kits with ethercat?

The only hitch on servo choice is there's only 100mm room for the Z motor. A 200w modern servo with a brake fits. a lot of others will be too long.

Rtelligent and Leadshine have ethercat dual motor stepper drives. example  www.rtelligentglobal.com/ethercat-stepper-drive/   and www.leadshine.com/product/2EM3E-522-14-15-990-69.html
If space is an issue, there is always NEMA 17! there are 3 and 4 motor options I've seen recently but may not have been ethercat

nema17 ha! this is a 300lb machine, nema17 wont be moving it.

200w ac servo is fine for the z. I wouldn't go smaller power. A nema23 stepper would work, it would just be very slow, probably not getting past 1000rpm before the torque falls off too much.

And we're done. Coordinating to start production tonight. Eep! (goes faster when someone else does all the work... and pays for it. )

So, to be more coherent on the control desires....

1: A new UI skinning of (probably) qtdragon, possibly vertical layout. I'll do the layouts, I'll need help turning it into a real working UI.

2: A linuxcnc build with a configuration wizard that includes ethercat and modbus, atc types, and some specific presets for lemontart (and then presets for any other machine people like - maybe presets can be just saved out from peoples manual configurations and shared).

3: Jerk limiting.at minimum on any exact top moves. Secondary is to add it to other motion. Bonus points for integrating all the fancier TP stuff from the tormach 1500.

For the physical control, I'm going to do a printed panel, with waveshare touch display, and a common low cost passively cooled dual nic mini itx board. Just so its easy and standard. "go buy these things, assemble, load linuxcnc onto it and run set up wizard"

Found it! Moon Technologies have 4 axis ethercat stepper drives in a couple of form factors

I've used Moons motors and they are very high quality, way above steppers on line....

If topic but where in Canada are you? I'm travelling to Vancouver before xmas...
