Makerbot Customization
Cupcake Refurb Project 2013
As of June 2013, a number of major upgrades have been performed / are scheduled to make the cupcake more useful and relevent.
Completed
- X,Y mendel style with 10 bearings/axis <Thingivere link here> - PLA printed Y part cracked, only 9 bearings installed. Still runs well.
- Wade's extruder for cupcake [1]
- Hobbed bolt + gear from ultimaker spares
- Stepper based extruder - stepper borrowed from ultimaker.
- Old Ultimaker (ramps-like) board with arduino Mega that has to be returned to Fumon - Sen to provide alternative?
- X,Y endstops implemented with random mechanical switches found around the lab.
Todo / WIP
- Replace gen3 electronics (WIP)
- Tuning for new hardware
- Toolchain integration (Cura profile)
- Z endstops
- Blue Router or RasPi
- LEDs! - (one strip in place, needs wiring + config)
- Wiring and connecting ABP.
- Replace ABP belt
Tuning
- X,Y,Z Steps_per_unit (Seems OK, but confirm)
- Extruder (lots of todo)
- Thermister (100k, which model?)
- Cura plugin for ABP at end of print?
Nice to haves
- Z axis replacement (z-rider?)
- Better bolts to allow for proper maintenance of wades extruder. (Needs at least 2x hex-head M3 bolts 45+mm to work properly.
- Better hobbed bold (Aonomus discussing milling makerbot-style pulley?)
Parameters and notes
- Using Marlin firmware. Full configuration to be posted on github once it's more stable.
- Motor model: KYSAN SKU: 1123029. Using 12V, 0.4A. (xyz only, extruder = better motor.) - Set pololu ref voltage to a bit under 0.16v.) [2]
- PID values + thermo values being played with. Default values overshoot hotend significantly.
- See reference values here: [3]
Historical
The Hacklab has made a number of customization to our Makerbot:
- Thermocouple in the Plastruder heater instead of the default thermocouple (including adding converter board for signal)
- Heated build platform
