Greetings!

I have some 600mm Misumi 1515 Aluminum extrusion for my delta. I just ordered 500mm MGN12H Linear rails. I am not sure what length bolt and what size T-nut to order to mount the linear rail?

Any advice!

Thanks

Those look like the same rails on an Anycubic Kossel Linear Plus. The manual [gzhls.at] on page 6 says to use M3 8mm bolts. I'm not sure about the T-nut though. Hope that helps.

Thank you@!!!

I made "tnuts" for mine by drilling and tapping M3 holes in .5"x.125" rectangular aluminum bar. I used 2550 extrusions. 1515 is way too small unless you add stiffening brackets.

They make T-nuts for 1515, but I needed to know what size to order. I have 6 sticks of 1515 (600mm).

Maybe you haven't used it before, but it is 100% rigid. You are not bending this stiff. Plus, I'm adding the 12mm linear rail which is steel.

I believe initially they used M3 with square nuts. But I can see the benefit of T-nuts

I order from China, so it will take a month or two if I'm lucky, but I just ordered my linear rails, M3 screws and GT2 belt and pulleys.

You may change your mind when you try printing at >100mm/s
