If you're using the Makerbot and have issues with it, or have to do maintenance/modifications to it, please note them in the [[Equipment/Makerbot_Cupcake/LogBook|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.

====Temperature settings====
* [[JasperWallace]] printed a box for a [[BusPirate]], discovering that printed things shrink by 0.5% to 0.75%


===19/04/2010 Operator: Russ===
ABS melts at 220 °C.
* Motherboard + Extruder firmware to v2.0 release 1. HBP now internally powered.
PLA melts at 210 °C


===18/04/2010 Operator: Nandish===
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).
* was unable to find SDCard reader - printed via USB
* multiple failed prints at raft lay down
** unconnected HBP cables lifted plate while it moved warping the raft
** abs not adhering to HBP - maybe extrusion temp
** extruder ploughing up cleanly laid down raft in one corner and printing in mid-air at other
* resolved raft issues with calibration
* partially successful print aborted after abs feed caught on speakers
** several layers missed, extrusion resumed in mid-air, print aborted


===13/04/2010 Operator: Russ===
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.
* Installed heated build platform v2, externally powered.


===29/03/2010 Operator: Solexious===
The PTFE Barrel insulates the extruder nozzle
* First attempt, extruder was to close to the platform resulting in the abs being 'threaded'. After heating the extruder and manually feeding the abs the makerbot was back in working order.
*PTFE is a thermoplastic polymer. Its melting point is 327 °C, but its properties degrade above 260 °C
* The makerbot successfully printed a single, and a 2X2 grid of Hackspace Coins http://www.thingiverse.com/thing:2113


===29/03/2010 Operator: Russ===
The default "3mm" thermistor settings are as follows:
* After a couple more crashes, downgraded extruder to 1.5.
*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


===16/03/2010 Operator: Russ===
Yup, that should defo do the trick!
* Ambient temperature is quite a bit warmer now, which probably helps.
* Successfully printed a whistle! (the overhang on the top means it's not terribly functional but it finished)
* Across about 70mins of print time I had two crashes :/


===11/03/2010 Operator: Russ===
==Consumables==
* Received and fitted new insulator/barrel/nozzle/nichrome. Extruder is working much better now.
* Also received 5lbs of PLA. I don't want to use it until we've done the M8 nut mod to the extruder, and we've got a spare insulator retainer. So we're still on ABS.
* Upgraded motherboard to 1.5, extruder to 1.8 with heated build surface. My ReplicatorG is now 0013.
* Managed to successfully print an insulator retainer! It's a bit stringy but it's a start.
* I'm wondering if the thermistor is a way off. Fiddling with the thermistor calibration didn't get very far.
* I honestly think we're nearly there ;)


===02/03/2010 Operator: Russ===
I've bought plastic, lots of plastic.
* Filament drive pulley replaced. We now have 4 spares.
* Still hitting problems where the filament drive stopped and gouged a hole in the pulley, which seems to indicate barrel undertemperature or blockage.
* Tried increasing temperature. Increasing extruder temperature above 255 appears to cause the heater to run away. I melted the insulator. Silly me.
* Ordered new insulator+barrel+nozzle+nichrome.


===11/02/2010 operator; Glen===
ABS
* 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.
Black, white, clear, red, yellow, pink green & blue.
* 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.  


===09/02/2010 Operator: Russ===
PLA
* Extruder with 2 idler wheels doesn't appear to work at all.
Clear, green, white and metallic.
* Reassembled the extruder with one idler wheel, moving the drive wheel up the shaft a little.
* This works, but the extruder stalls after a random amount of time! WTF. We need a new drive wheel.


===08/02/2010 Operator: Glen===
Prices range from 4 to 2.5 pence per gram.
* Can printed half a large object with no warping by melting the raft to the print surface.
Put money for plastic used in the box marked Glen in the box store room.
* Print-head failed push plastic feed into nozzle
* Dismantled the print-head and found the gear that drives the plastic feed stock had broken in two and the two parts had ground against each other to produce many tiny metal shards.
* After cleaning the print-head the plastic would not come through unless pushed by hand.
===06/02/2010 Operator: Russ===
* Downgraded both motherboard and extruder to 1.5 firmware.
* Printing off SD card, no crashes observed.
* Managed to get about 80% of a shot glass printed. Glitches caused by contraction were an issue, and eventually it got knocked off by the print head.
* I'm fairly sure the hardware is working fine. Problems I'm now seeing are caused by either ambient temperature/airflow or skeinforge settings.


===04/02/2010 Operator: Russ===
==More information==
* Walked in, started it up, extruder works fine.

* Extruder idler pulley needed re-adjusting twice. ('''Note:''' that the thin silvery metal bar in the Makerbot toolkit is designed to be used as a spacer for this.) Should be done up nice and tight now though.
* Continual tweaking of z-stage stepper strength, now at about 75%
* 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.
* I managed to make it print 1/3rd of a shot glass, then it crashed. (About 60,000 gcode commands/30mins in.) Need to know what firmware to put on it to stop the crashing.

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.
