High Torque Motor Z Axis

[John S]

Generally the Z axis does not need a motor the same size as X and Y.
The X 3 is different though, on mine i have SY60 on X and Y and a SY86 of Z.
The X3 Z axis is a heavy axis.

Very true Gary about the X3 head but the 312 oz in motor on 2:1 works just fine and this is without the gas strut.
My small Teckno Isel router that I bought minus all electronics and motors is now on 210 oz / in all round and running at 40 volts and it screams along for it's size but then again the head isn't that heavy on this one.
Again all direct drives onto 5mm pitch screws.
It remarkably accurate, here's a badge I did as an example.



Note the g's on the tails, they are all exact and no undercutting and wandering, this was engraved in brass, raised letters at 1200mm / min.
