eShapeoko carrier plates - through holes or M5 threads

Post by Georgei » Fri Jul 31, 2015 12:14 pm

I am redesigning my carrier plates in order to make them more maintenance friendly and since I will do all this I will also upgrade my motors to Nema23.
The new plates will be from 6mm aluminium.

My question is the following: on the original plates most of the holes are through and everything is being held in place with bolts and nuts.
One of the think I hate is to have to disassemble half the machine in order to change something.

Is there any strength issues if instead of nut and bolt I make M5 threads on the 6mm aluminium plate and just bolt everything to the plate?

Any input is welcome.

George

I think there's value in keeping the V-wheels and maybe the idlers on through bolts -- you can tighten the heck out of them and you don't risk stripping the threads. The motors can be on threaded holes just fine, and limit switches too, by all means.

The idlers were one of the reason that I wanted to have threads.
I want to remove one of them and I have to disassemble the all carriage and rails.

It's too darn easy to strip threads in 'thin' aluminium, so I really advice against it on idlers and v-wheels.
Instead, try to find alternative placements so that you don't have to disassemble everything...

Do you think that 6mm thread (the thickness of the aluminium plates) is not enough for the idler's?

I think it's enough. Especially if the plates are made of a decent alloy (not 1050).

That's the best stuff you can buy without paying a lot of money.
