New Plasma build in OZ

Been doing some work on the ganrty design.

Opinions on mounting the stepper locations for the X and Y
Im looking at mounting the steppers at the end of the slides.
Seems to make sense for the Y lowering the gantry weight.
Not sure if it worth doing the same on the X axis.

What are everyones thoughts?

Statewide Prices

4000mm rails $700 each
Carrages $85.50 each
Scraper kit per carrage $22.50

prices ex tax

Steppers should be mounted as close to the rails/carriages as possible, keeps the mass near refference point, the overall result is less vibration.

Thnaks for that.

So mounting the Y stepers on the carrage using a single belt fixed at both ends is better then a looped belt with the stepper on one end.

In other words the higher overall weight of the garnty is less of a concern than the vibration in the belt.

Always and yes.
Using reduction would be nice, direct driving the belt is also usable with microstepping drives.

I just checked Industrial Dynamics, they quoted me $531.95 for 3 m of HGR25 in June
