I think one that size should have two. Our 2x4 with 125 lb. gantry has two and I can't see one as large as yours getting by with only one motor. Racking issues aside, I just think it needs two.
Do you mean 20mm screws?I'm using NEMA 34 with 20mm rods.
No, I meant the linear rods that the bearing blocks travel on. Sorry for not being more clear. The boss was wanting to leave early, so I had to post like NOW. :grin:Do you mean 20mm screws?
They don't have to be that long. You can butt shorter sections against each other to form one continuous rack. Just make sure they're straight.Thanks for this insight! So I guess the next question is: Where can I find a rack and pinion that size?
