I’m currently building the MPCNC (metric version), but I’m having some troubles to get the correct screw size.
I’m building the Roller and looking at the instructions I need the M8 65mm bolt. Sadly such length is very uncommon: locally (and even online at a reasonable price) there are only 60mm or 70mm lengths.
I can easily use the 70mm length, but I just wanted some advice if the extra length could pose any kind of issues, I’d really wish to avoid dismantle everything because of a screw…
So I can use it? If so, the nylon nut won’t tight until the end, there will be 5-6mm of screw and then the nut, is that ok? Reading the instructions it says that nut should be extra loose.
Should I use a regular nut and then lock it with glue? Or it’s even better to cut the screw to size (I’d really wish to avoid that…)
