Mendel90 3D Printer
- Owner/Loaner: ENTS
- Make/Model: Mendel90
- Usability: WORKING
- Contact: User:Hov
- Where: Main Workroom
- Certification Needed: YES
- Hackable: NO
- Estimated Value: $600
Currently working with small issues. Interface is at http://members.ents.ca:5000
Who Can Certify You?
200mm by 200mm by 200mm build volume. The X and Y are actually a little less than that but the Z is actually about 208mm.
As long as the Slic3r settings match with the filament size temps the only other setting for the printer itself is the nozzle diameter. Current hot end is 0.4mm
When connecting to OctoPrint if the printer (the arduino) isn't connected to the RasPi then use:
- Port: /dev/ttyACM0
- Baudrate: 115200
- Print not sticking to bed
- PLA or PLA/PHA (ColorFabb)
The firmware has been modified to make extruder 1 (of extruders 0 and 1) behave like extruder 0. There was a magic smoke event that cooked the current limiting resistor for the extruder 0 heater.
What Could it Use?
- Kyle will be working on a Bowden Tube based extruder to move the stepper and cold end off the X-Carriage
- A mounting system/brackets/case for the LCD screen
- A Cover/Case/Fan Mount for the electronics
- The X carriage is noisy. It's probably because the linear rods are slightly smaller than the bearings. 8mm rods should be swapped in.
- Mounting system for the RasPi and USB Hub
- Carrying Handle
If you're willing to tackle any of these please let someone know.
Working on it
- User:khawkings - Bowden Tube extruder
If the hot end stops making itself hot then unplug and plug back in the connectors for the hot end on the x-carriage (the 4 pin connectors to the protoboards)
