[MakerJim]

Hello, Mahmoud. Welcome to the forum.

@Mahmoud_Hassib

Can i ask you what printed parts fits 24mm stainless, did you go with the 23.5 version or the 25mm version, since im building mine and already have all the tubes cut of 24mm stainless steel

Their last post was in July of 2021. You will probably have better luck opening a new thread, or replying in your existing thread:

2 sizes of Stainless steel tubing

Hello , to everyone from sunny Egypt, For almost the last 2 years i have been hording parts for my MPCNC build , and the last of them is tubing and i have sourced stainless steel from a friends company and it was cut and polished to perfection, the current problem is in regards to the printend parts since my stainless steel (od 24 mm) so i dont know which in the 3 sizes of printed parts will be suitable, secondly after going through the build manual i have found the the z tubes need more id …

I think you had pretty good advice in this post in your original thread:

@kvcummins

I would say go with the 25mm version, as those slightly smaller tubes are going to be extremely heavy. If you look at the Primo Parts list , it will give the full breakdown (including suggested wall thicknesses).

edit: I didn’t fully read/comprehend your post the first time… You should probably get the other 6 rails recut with the 25mm, but thinner walled stock. Pushing 1.6kg+ of just gantry around (not to mention whatever spindle you add to it) is going to seriously stress your machine (and really slow it down due to acceleration issues).
