8020 belt driven 3 axis

[Ross77]

Good choice on the stepper drives. Ive got the 542's and their really good.

I take it thats not the actual drawing of your machine but just in case, Don't mount the main y beam like that cus it will move all over the place. Extend the side supports up and fix the beam top and bottom. if your using the plate and skate bearings then also extend the plate to the side support. that will make it much more rigid.

Theres quite a few other bits that could do with changing but I dont want to be to negative

I spent the morning wiring up a test rig to see if I can get the stepper to turn, then the missus arrived home from work and we went out, so maybe later.

The drawing is a machine i'm modelling my build on, I plan on resting the Y axis gantry as per the drawing but using some plate material on the end face and down the side of the gantry support for strength, and yes I plan to extend the carriage plate across the full width. This decision is based on how I think I can physically secure the extrusions together.

I generally tend to over engineer things, so we'll see how this goes. I'm held on the main framework waiting on some more extrusion, i'm getting it buck shee, so willing to wait, well so far ....

Comment away about your ideas for change, all welcome, this is all new to me so I like to weigh up the options.
