Hey Guys,
Just want to share some of my recent work, my first machine was out of MDF and cutting area is only about 12x15inches. I was quite limited, it was slow with 182oz nema and unbiopolar driver. Therefor I went ahead and look for new parts and want to build a bigger/better. I am currently shooting for 24x48inches cut area.
Here's the Z, I got this off ebay, have to take the whole thing apart and remove the coreless motor that came with it and cut off a bunch of stuff and use my mdf cnc router to cut a g-10 plate out... this will allow me to mount my own Nema stepper.
On the X axis, it was a hard decision whether to make it out of MDF again or aluminum. But I end up with aluminum purchase from HomeDepot. Total cost of aluminum for the X so far is 30.00.
I was thinking to mount the X motor inward drive by belt... Just simply to make it more compact, since I will be using the Nema 425oz and it long, having it on a side and moving back and forth would be crazy.... Do you guys think it worthed? By the way, will belt cause backlash?
Here's the pic so far.
