So far, these are the points that I'm considering...
Decisions:
- Go with 8mm vs 10mm slides - leaning towards the 10mm right now. It seems to have less vibration, and I can get printed parts that will fit it.
- Build a MendelMax 1.0 or 1.5 - Pretty much a no brainer, 1.5 it is!
- Use optical or mechanical end stops - I have a set of optical on the Darwin, so I'll probably just use those
- Type of X/Y carriage - I need to research this more.
- Use a regular stepper or one of the low weight steppers to drive the print head - I'm tempted to go with the smaller stepper eventually, but for now I think I'll stick with the regular NEMA17
- Heated or non-heated platform - heated for sure, probably with a glass base
- Type of print head - I'm leaning towards the budaschnozzle. The printed parts I'm looking at support this.
- Type of electronics - I'm going to use the RAMPS/Arduino Mega system with Polulu stepper drivers.
Upgrades:
- Glass print surface - from what I've heard, this requires less power then an aluminum print surface; aluminum being basically a big head sync.
- Spring mounts for the print surface - Probably a good idea. Don't want to wreck anything when/if the print head crashes.
- PanelMax electronics that allow you to tweak some parameters, and send jobs without a laptop - Very intrigued by this. This could be an upgrade for later.
- Spool holder on top - why not!
- LED lights - bling!
- Black Mitsumi extrusion - why go with the stock silver?
Other notes so far
- Make sure that your steppers require no more then 2amps, else the drivers overheat.
