So my Maslow arrived (woot!) and I have proceeded through the electronics steps. Now on to the frame. I ma new to CNC and DIY so this will be an adventure and also please bear with my newbness.
So, I was looking at the bar bolt frame as my starting point. But, I am hearing that the bottom corners are issues accuracy wise, and that I may need to make some changes if I want to go full 4 by 8 as well.
First thoughts were to
A) Use a unistrut (or equivalent) top 10’ bar, versus 2 by 4.
B) Run it slower in the lower corners
C) Put the sled on some UHWE plastic sheet
For A) it looks like the strut could bolt right in in so far as the frame top bar goes. But, then that would leave a question over best way to attach motors. Thoughts?
For C) Would this work? https://www.amazon.com/dp/B0789Q5HRV/ref=twister_B0789N32QZ?_encoding=UTF8&psc=1 And if so how best to attach to plywood sled. Epoxy of some sort?
Or do I need to consider wider from the get go? To allow the sled some area to coast over as well as fix accuracy in bottom?
