How about my other question?
Will 4 nema23 4amp motors from cnc4you drive my 60kg gantry when using the machine vertical? :D I assume 1 motor each for y and z is okey and 2 for x (standing axis)
Like I wrote I will be using 80v digital drIves with 68V psu...

Have a nice weekend
Yes they will be ok. My machine uses same size motors with similair weight gantry. However I have put counter balance on the gantry to stop it dropping when motors are un-powered.
The motors handle the weight perfectly fine without counter balance and it's just there to stop gantry falling when unpowered. However it does assist the motors meaning can run slightly higher rapid feeds than when counter balance isn't used.
If you park the gantry on end stops each time motors powererd down then wouldn't need counter balance but the way I use my machine means often power down motors through out the day but control is left on so don't want the hassle of parking each time.
