Please don't touch or fiddle with the Makerbot unless you have been trained.
Status
Replacement heating resistors have arrived, but are not quite the right size. They have been fitted, but were apparently broken again very quickly.
See the operator log for more information. Better still, update it as it's totally out of date.
Those who don't learn from history are compelled to repeat it .. so KEEP THE HISTORY !
Model
We have a Makerbot Cupcake (batch 9, #402)! It's cool.
Specification
Instructions
If you haven't used it before, please contact Glen or Russ and get him to show you how it works.
If you're using the Makerbot and have issues with it, or have to do maintenance/modifications to it, please note them in the operator log. This lets other users know what the state of the machine is, and helps us to avoid repeating errors which lead to breakage.
Calibration
Connection voodoo
- USB cable maker bot
- USB cable laptop
- Makerbot PSU power on
- ~RepRap motherboard power on
- replicatorg
Temperature settings
The PTFE Barrel insulates the extruder nozzle
- PTFE is a thermoplastic polymer, its melting point is 327 °C, but its properties degrade above 260 °C
The default "3mm" thermistor settings are as follows:
- Temperature of Raft: 230.0
- Temperature of Shape First Layer Outline: 215.0
- Temperature of Shape First Layer Within: 215.0
- Temperature of Shape Next Layers: 220.0
Troubleshooting
- Replacing the heater barrel
- Uncloging the extruder
- Extruder
- The extruder mechanism is now the MK5 plastruder.
- For unknown reasons, the heater resistors needed replacing. Replacements were obtained but were the wrong physical size (didn't fit the mounting hole spacing). The correct resistors are 5R, 10W, 1% and the mounting screws are M2 at the diagonally opposed corners of a rectangle 15.9 x 14.3mm.
Consumables
I've bought plastic, lots of plastic.
ABS Black, white, clear, red, yellow, pink green & blue.
PLA Clear, green, white and metallic.
Prices range from 4 to 2.5 pence per gram. Put money for plastic used in the box marked Glen in the box store room.
