* To print warp free large objects heat the perspex plastic bed to 100'C with the hot air blower then make sure the first two base layers are stuck to the bed by adjusting the Z-axis height. Don't use the electric fan heater as this increases cooling of the plastic. I used the hot air de-soldering blower at 100'C to keep the plastic warm while printing, though I didn't try printing without this.

* The extruder gear wheel has a part missing from it that limits where the plastic feed can rest against the gear teeth. Until the drive gear is replaced the plastic feed can work it's way next to the idler wheel where it will no longer be driven. I tried putting two idler wheels in to stop the feed from having any space to get away from the drive gear, but this didn't work so I went home.

* Consider selling the printer to some poor fool on eBay, as far as I know it's printed no large objects despite receiving dozens of hours of maintenance and is clearly possessed by angry spirits.

* Accidental Z-stage/build platform collision required re-levelling of Z-stage (seems the best way to do this is by releasing one of the Z idler pulleys and twisting the studding, instead of fiddling with the nuts). Seems pretty smooth now.

* X belt tension was too low, there was a lot of slop. It's pretty tricky to get it tight enough.

* Lots of bolts on the XY stage were loose! This makes a horrendous racket when it's actually printing at full speed... Tightened them up

* Packed both X runner bars with hot glue, they were also moving about and making a racket.

Please don't touch or fiddle with the Makerbot unless you have been trained.

Training Session 1: Wed 7th September @12:30pm Samthetechie showed Billy Smith

DO NOT UPDATE OR EDIT THE FIRMWARE ON THE BOARDS.

Please document the customizations which prevent upgrading the firmware <3

Status

To try to reduce the stagering amount of damage the Makerbot sustains I've added a key. operator log for more information.

Model

We have a Makerbot Cupcake (batch 9, #402)! Now modified to a hipsterbot, extended x, y, z-axis. It's to 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

  1. USB cable maker bot
  2. USB cable laptop
  3. Makerbot PSU power on
  4. Use key to turn power on to system
  5. ~RepRap motherboard power on
  6. replicatorg

Temperature settings

ABS melts at 220 °C. PLA melts at 210 °C

Use ReplicatorG 0025, setting the Machine driver the "Cupcake w/ automated build platform", but the Gcode profile set to "Cupcake w/ heated build platform" (for now, because we don't have a scrubber).

The heated build platform should be set to 100-120 °C, and shows up in GCode as the "cooling fan". If controlling the extruder, set it to 255.

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

Yup, that should defo do the trick!

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.
