how do you program such a thing into an ultimaker, just got mine assembled yesterday.

2

in cura you can add gcode which will be runned after print (end.gcode)

Cool! I’ll look into it further!

so what does this m40 thing mean? http://reprap.org/wiki/G-code#M40:_Eject (sorry im so new to this gcode thing)

This only works if the bed has almost no adhesion. I tried once without success… :slight_smile:

Be a little bit careful. The stretchy bracelet is very flexible and has a limited amount of area in contact with the bed. The greater the contact surface area, the harder the object can be to remove from the bed. This will also be affected by the surface that you print onto.

Thanks for all the advice!

But how exactly would you Program this into Cura?

@Sanjay_Mortimer Has this sort of thing nailed using his mendel 90. https://www.youtube.com/watch?v=lra0YW3hG6Q&feature=youtube_gdata_player

M40 isn’t used by anyone really. You’ll notice it says “conveyor belt”, which is an old (failed) design by MakerBot. Generally you’d do a G1 to a position in X Y to move out of the way (ex. G1 X200 Y200), then G1 Z0.5 (so the nozzle doesn’t touch the bed), and then another move in X/Y in order to push the piece off. Afterwards, probably rehome just in case you missed any steps while pushing the piece.

I was about to say you should include a ‘wait till bed cools’ command too but would be a bit pointless with an Ultimaker.

12

printing PLA onto hot glass (like a Mendelmax) you can make parts pop right off the bed when it cools, then this would be easy to do with arbitrary parts, not just low-adhesion parts like the bracelet.

@Sparr_Risher Ultimakers don’t have a heated bed.

Note the big brick mounted just on the left side of the hot end, strongly fixed with his external large protruding side about 1 cm before the hot-end to be sure it hits the object BEFORE the hot-end :slight_smile: …

assumed the brick was a fan…
