SP13 and various plastics ....
I decided that SP13 will be it, and I now have the kit of parts (yes it took forever to get to the UK!) and am looking at starting printing. I'm in no rush and want to do this well, to the extent that I want to ask everyone's experience with plastics other than PLA. For example I have PC-CF (polycarbonate carbon fiber) with which I recently made parts for a CoreOne upgrade. I'm very impressed by that material; the CoreOne prints with it very well and it comes out so smooth and is inherently 'tough'. I've also got ASA. The PC-CF is black so does not lend itself to some aspects, but I'm seriously considering the gears, thinking that the hardness and stiffness might reduce friction. For the frame I might use PETG, but ASA is also a question, and both are stiffer and mechanically stronger than PLA (though I agree in limited ways).
I'd welcome your thoughts or experiences.
PLA is an option for me but I currently have a greater range of suitable colours in PETG.
My sp15 stopped. It has worked flawlessly for 4 weeks. I think sp5 stopped for the same reason as the SP5. The center friction assembly is my problem. I am never certain how 'tight' to bind that friction assembly. Tightening it up , or pushing back from the front of the assembly ,result in a stronger 'beat' and longer run. If it is too lose the clock tick is not as strong ... if any of this makes any sense ...
