Thanks Al, You did help me a lot 12 years ago with my retro. Yes, tachs as well on that system.
At the outset I was looking for PM motors in the 250 watt range and just twiddle it until it works in my semi retirement.
ps, I've a lot of boards from that Bandit system I'd sell cheap

You are not going to do much with 250w motors 400w would be the minimum and 750w the norm for a machine 2 x 4 size, 250w will work for a laser or 3D printer it also depends on your Ballscrews or how you are going to move each axis

Hi,
I have to agree with Matec, 250W is minimal.

The Delta servos that I have been recommending are 60mm frame (24 size equiv) at 400W and smaller, including 200W and 100W.
Noticably the 400W B2 series servo kit is $398 while the 200W kit is more! So why would anyone bother with 200W when you can get
a 400W for less. The frame size is the same, but obviously the 400W servo is longer.

The 750W B2 series servo is only $438, so only $40 more than the 400W. Admittedly the 750W has an 80mm frame so is a little bigger, which may or may not be an issue
if you are retrofitting a machine.....but nearly twice the power for only an extra $40, seems like a no-brainer to me.
