Up and Running CoreXY!

Big update today! The Filameister design is finally built in real life and seems to run very well!

All the parts have finally arrived, the machining is done, and the XY portion is all wired up. This is a temporary acrylic prototype to discover any loose ends before final design modifications and the real build in aluminum.

Tested so far:

• Duet3D Wifi - Huge fan of the hardware and the web interface!
• Linear bearings - we use these at work so I knew they would be great
• 0.9deg NEMA17 stepper motors for higher mechanical resolution
• Genuine Gates belts and pulleys.
• Optical end of travel switches. Specifically SUNX PM-F24.
• Fan ducts for hotend heatsink and part cooling
• PT100 sensor for the hotend.
• V6 hotend mount and heatsink ducting

Left:

• Design Z axis and heated bed
• Design electrical cabinet / wire routing
• Wiring for hotend, fans, sensors, LEDs (pcb?)
• Bracket for Bontech Extruder
• Filament Reel Mount
• Test polycarbonate fan ducts in close proximity to hotend for thermal issues (heat shield or insulation required?)
• Finalize Z stroke and source Z axis leadscrew and bearings
• Finalize enclosure size and panels
• Source aluminum components
• Build the final optimized printer design!

Here are some more various pictures of the progress:

CoreXY re-design

So I took the plunge and re-designed the XY axes to use the E3D style CoreXY design without the crossing belts. I like their design because it looks simple to build and stiff structurally.

Currently, I have the XY system basically designed around the components I have sourced. In other words, adapted to the linear bearing lengths, motor sizes, V6 hotend etc that I have already acquired.

I will be prototyping the XY motion this weekend hopefully if the rest of the shoulder bolts arrive in time! I am going to prototype the aluminum plate and crossbeam in acrylic because I can laser all the holes in the right spot with the cnc laser at work. If the prototype works, I will commit to making an aluminum version.
