A recent order required a number of large ABS+ parts, so I ordered a 500mm cube printer to handle them. Tiny Machines got the machine to me about a week after ordering, so they did a great job rushing it out for me. The machine as it comes is fairly simple. They do include a filament runout sensor, however there is no builtin automatic bed leveling. With a 500mm aluminum plate, that gets to be a bit difficult. I got the machine with the Keenovo 110v heated bed. This is a 1300w heating element under the entire thing. The stock board comes with only a 300mm heater. Tiny machines was also able to put in an E3D extruder along with a plated micro swiss nozzle.
The first thing I did was set about building an enclosure for the new printer. Once I had a wooden frame, I mounted the bowden extruder as close as the existing wiring would allow me. I added a PEI sheet to the print bed. I printed a new extruder mount with a BL Touch sensor mount out of Polymaker PC-Plus.
Here are the changes from stock in my hit list :
- Heated enclosure
- Wooden box built, need to build the door with a window
- PID controller is in
- 24vdc 300w heaters are in
- Foil insulation ordered
- 12in Aluminum plates for mounting ordered
- 120mm recirc fans ordered
- Stiffening
- Thingiverse kit printing
- Hardware all ordered from amazon
- Rods lengthened to 36in (measures at 28, so ill trim as needed)
- Need to figure out linear rail or rod and bearing for X axis
- Find solid leveling pads for under the build plate
- Hotend changeout
- Temporary setup with the e3d and bl touch on bowden is printed
- Need to finish wiring BL Touch
- After X axis is strengthened, change to direct with a titan aero kit
- Electronics
- BL Touch wiring
- Change main board to 24vdc
- Add ssr relay and incorporate bed heater direct instead of on PID
- Octopi added
- Print mount for 120deg camera
Hopefully when all of the above is done, Ill have something as reliable as my Taz 6’s with a 500mm cube build volume! Stay tuned as I keep running with this thing!
