I am considering a DIY cnc router build using SBR linear rail.
300mm/700mm/1100mm are the rail lengths I plan to use.
16mm would be 3/4 the weight of 20mm.
I am going to start with an MDF design - but may rework it with 8020 eventually.
Overall price difference between 16mm and 20mm rail is not that great.
Is there any reason NOT to go with the SBR20 instead of SBR16?
