I created 2 adjustable steppermounts.
This makes it easier to adjust the tension in the belt-system.
The tension works with a big M8 screw that pushes against the stepper.
I'll add a knob later on that can attacho onto the screw-head
Extra requiremends: 4 pulleys (2 with teeth and 2 without)
Mouting to the frame is with M4 bolts; the pulleys use an M5 bolt.
First of all, this is Version 1 of my CoreXY conversion build and my first attempt.
Some parts need a complete make-over.
My part cooler is my first attempt (ever) of creating a fang cooler in Fusion 360.
The real-life results of this are not too good (the fang is too close to the hotend).
I'm in the process of redesigning this :)
Also, the stepper mounts are currently non-adjustable.
I'm designing new stepper mounts that allow for belt-tensionning.
Will be posted in a future update :)
For now, my unofficial BoM:
- 3* 400mm MGN12H rails
- 1* 400mm 2020 extrusion
- 5m belt
- Pulleys (when using the adjustable stepper-mount)
- 8*20t pulley (M5 bore)
- 4*blank pulley (M5 bore)
- 4*M5x40 (for the XY connectors)
- 50*M4x10 (used to bolt down all the corner-stuff)
- 50*M4 T-nut to bolt everything to the frame
- 100*M3x8 for the rails
- 100xM3 T-nut to bolt everything to the frame
- 25xM3x10 to attacht the carriage to the rails
Probaply more bolts as well but if you order smart @ aliexpress it won't cost you much to order a stash of nuts 'n bolts :)
The XY-Cap needs to be printed twice, it fits on both sides.
- I used M5*50 bolts for the wheelhouses and the XY connectors
- All the frame-mounting is with M4
- The hotend-mount is mounted with M3 bolts
The stepper-mounts and the wheelhouses double down as frame-corners, i printed them pretty heavy for strength.
I used 0.2 layer height with a 0.4mm nozzle to print everything.
My build is greatly inspired by LordKyleOfEarth's build (https://www.thingiverse.com/thing:3094320)
But i was stubborn and wanted to design it myself sigh
Everything is designed in Fusion 360, i named the parts as where they need to be :)
