Hello, I am new here. After starting at 3D printing with a Bibo printer, and spent a lot of time to ... fix it... I have understood 2 or 3 basic things:
- Industrial FDM printer are out of my price range.
- The consumers FDM manufacturing industry is driven by the price consideration and flooded by Chinese crap parts.
- Technical solutions are also driven by the profit consideration.
So, I decided, like many of you, to start from scratch, and build my own printer:
Briefly:
- Core X/Y geometry
- Inspired from the DD UMMD ( thank you DD (tu) really useful writings ): rails, belted/worm gear lifted Z axis , separate Z frame, etc...
- careful attention to basics technical details: rigidity, for example.
I would like to hear you about this question :
Belts to move the X and Y axes :
My though was to use 12 or 15mm wide belts in order to reduce the ''spring effect'' of the belts driving a quite heavy carriage: probably near 2Kg once built.
I found GT2 12 mm wide 2mm pitch belts, and 15mm wide GT3 3mm pitch belts.
In your opinion, is there a real down side to use a 3mm pitch ( 0.9° motor) on the X / Y axes, instead of 2 mm ?
( from an accuracy point of view, with a standard 0.4mm nozzle)
