Have completed all four corners now, just started on the X and Y assemblies. As these are almost solid prints for me they take both allot of ABS filament and time to print. Yes I’m printing in ABS, mainly for strength, to bring the parts into tolerance I’m hand machining where necessary. But so far I have only required an Adjustable Hand Reamer, to bring the 25.0mm holes/clamp arcs into exact sizes, as most other parts are spot on.
Fasteners will never be an issue as there are many places here in Sydney to source the nuts and bolts.
As far as the Electronics, Steppers, Drives and Bearings, I have almost 100% completed my list of sources.
