"Candy Apple" printer first pic and video (19 replies)

Thanks to everyone here for the advice, especially dc42.

Previous forum topics for printer:

First Build Hiwin CoreXY
Duet controlled CoreXY - Install Procedure

Design ideas explored:

1. Use all Hiwin style linear slides for all movement to increase precision
2. Reduce part count
3. Reduce weight of linear moving parts in XY plane to minimum (currently 173gm, will be 150gm shortly)
4. Box design for easy future enclosure (to control print environment temperature, air convection, and add reverse pressure fume filtration)
5. Maximize build volume for minimum exterior dimensions (build 20x20x27cm in 27x31x36cm box)
6. 32 bit processor in the print controller

I believe that the weight of moving parts in the XY plane is the lowest of any printer with this build volume (or maybe any build volume). Anyone else know of a lighter movement?

I am hoping to show it in person at MakerFaire NYC September 26 & 27, but I just finished building, so may be too late for them to give me a booth. If anyone has suggestions on how to get a late application approved, please let me know.

In the picture, the dust covers were printed on a bed without tape, so they warped. I will be printing new dust covers shortly.

Sooooo... Finally the picture:

Maybe you can tell why I am calling it Candy Apple?

Thanks again everyone,
