My initial solution to this is to obtain the CAD files and reduce the size of the captures. Upon searching the forums it appears that this isn’t a solution.
The nuts which do fit the captures are only available in wider thread sizes, I try using these size bolts but that splits the prints, even if I drilled them first. Having captures that are too large is worse than having no captures as it’s impossible to get a spanner or socket into the gap.
As I’ve had my CNC for 5 years, I’ve noticed many of the pieces are starting to crack and need re-printing I’m hoping to obtain some edited parts before printing because I dread taking the machine apart and re-assembling it as the nuts have always been a major drama. You won’t believe how much pain I had completing the construction of the inner tube Z parts.
I was wondering if there is a solution to this.
Thanks
I had a similar problem when I mounted the Burly MPCNC with metric nuts.
I used a quick and dirty solution that worked very well for me: I inserted the screwdriver blade to help lock the nut and was able to tighten everything perfectly without wasting time
Hope this will help you
It doesn’t take much to jam a nut. In another situation recently I had a metric/imperial conversion in a refrigerator part and plead guilty to printing an adapter like this - 0.5mm bottom thickness and from memory about 1.8 for the walls? All perimeter no infill - it was mounting a plastic tray to a metal subframe, with no access for a spanner.
I just figure that if the plastic compresses a bit it doesn’t matter, but in the case of the MPCNC just make it out of the same material if the screwdriver trick doesn’t work for you.
