Wiper
This is a page to document experiments and settings and fantasies for a build platform wiper.
Many details mined/trimmed from responses on http://groups.google.com/group/makerbot. (mifga)
Experiments in Progress
- Be the first!
Skeinforge Code Hooks
- Are there any?
Fantasies, Dreams, Aspirations
- Servo-Driven Wiper (Cathal Garvey from googlegroup)
- If you were using Glass and PLA, you could do that! And with a little servo-driven "wiper" at one corner, you could achieve what Makerbot crew have been thinking of for ages; mass production of parts with fully automated part removal!
- I'd construct a thin glass interface on top of a metal plate with a ring of nichrome, with a Peltier plate beneath, and another metal plate as a heatsink beneath that again. It'd be a fat setup, but if it worked it'd allow you to churn out identical parts in really short order using just a little extra Gcode to control your platform and wiper.
- Process:
- Nichrome-heat platform, print on the hot glass with PLA.
- As part finishes, rapidly cool platform to "pop off" the PLA.
- Move stage to rear right of chamber, have a little servo sweep the piece out the back of the Makerbot case. You could also rig up a mechanical setup with a hinged platform so that when the platform hits the rear of the chamber, it levers up and drops the part.
- Heat up platform again, return to 0, resume printing next part.
