This page documents Ultimaker #1 (Guy). The printer lives on the bottom shelf of the 3D printer tower.
- Last known good settings: 220°, 110% flow, print 60mm/s, travel 120mm/s, 0.4 mm nozzle size, 2.85mm filament size.
- "Canada 150" Red PLA (from Filaments.ca)
- Works well using Blue painter’s tape without using the heated bed. (Same setup as Ultimaker 2)
- Cura 15 Settings here
Known Issues and Fixes
- IMPORTANT: OctoPrint will disconnect from Ultimaker 2 if Ultimaker 1 is powered on. If you want to print on both (or will want to eventually), power both on before starting your print on Ultimaker 2
- For better results, wipe the Blue Tape Sheet with Isopropyl Alcohol a few minutes before starting to print.
- If a large solid area is under-extruding then try printing PLA at 220° and 110% Flow.
- To easily change the filament, rotate this printer 90° -- so that the filament spool points towards the shop door end of the shelving.
- Ultimaker Original with extruder drive upgrade
- 210 x 210 x 205 mm print volume
- 2.85mm filament
- Absolute max temperature: 250 C
- Heated bed for ABS (on second power supply)
- It is managed and accessible from the web GUI: http://octopi.hacklab.to/

The head was jammed up real good, had to put in some elbow grease to clean it. So apparently a 5 mm long piece of filament had broken off and got stuck in the space where the bowden tube meets the teflon coupler (I think it was in the teflon coupler). So filament was blocked from entering the metal throat. Had to heat up the block, unscrew the nozzle, and poke a thin screwdriver up the throat. Kept poking and removing molten plastic, then finally pushed up on the blocking piece and pushed it through to the bowden tube, which I then disconnected and got that bugger piece out. I must say it was my white whale.
Prints as usual now, which is pretty good.

|Jun 7, 2017||Stopped Extruding! ... Something like a C-clip has been lost on the Geared/Knerled shaft. .... For now use a copper wire to hold that shaft in place. The proper part needs to be obtained and installed.||Allen|
|Jun 7, 2017||Lubricate the Z screw using Superlube Synthetic Grease.||Allen|
|Jun 7, 2017||Heat bed still "cuts out" and drops to about 28°C after less than an hour of printing.||Allen|
|Jun 7, 2017||Switched bed heater to the second relay on the breakout board, it verks!||Igor|

|Mid-2016||Nozzle cleaned, Bowden coupler springs replaced. Prints well. Use "ABS juice" to stick ABS prints to bare bed. Prints PLA onto blue tape perfectly as well.||Igor|
|Jan 28, 2016||THE QUARTERBACK IS TOAST. This printer isn't working. The extruder is spinning but not pushing ABS through. I've done as much troubleshooting as I can without risking screwing stuff up. I've sent a query to the mailing list.||alaina|
|June 8, 2013||Added tool holder onto side of Ultimaker||Norm|
|May 14, 2013||Tensioned X/Y belts, switched to white PLA and tested new experimental settings. Readjusted Z bed height, printed stuff.||Norm|
|May 11, 2013||Rod endcaps removed, threadlock (blue) applied to the M3 screws and setscrews locked into place to prevent loosening.
Lubricated Z axis and gantry system.
|May 1, 2013||Printed and mounted new Z home switch retaining mechanism and calibrated. Z homing much more accurate.
Observed further inconsistent extrusion, further investigation found online that the knurled bolt is only useful for the last 3 mm nearest the groove for the delrin clip. Adjusted bolt positioning to move good knurling into position, no further grinding or slipping observed, consistent solid extrusion demonstrated.
|April 30, 2013||Installed new e-panel composite based build platform.||Geordie|
|April 29, 2013||Printed and installed new extruder feed gear to reduce backlash during retraction.
Observed inconsistent extrusion. Small gaps appearing in extrusion, yet full infill occurring on layers otherwise (ie: not clogged).
|April 27, 2013||Print quality degraded significantly mid-print. Hot end disassembled, burnt PLA removed from brass tube, and dust/dirt removed from teflon-PEEK interface. Print quality returned to normal. Clogged again, cleaned more thoroughly this time. (Used 1/8" drill bit to handheld scrape out burnt PLA very carefully.
PLA diameter changed.
|April 24, 2013||Squeaking noise observed from Y axis axle.
Endcap inset screw noticed to be loose, requires new endcap to be printed, and screw not to be overtightened.
|April 12, 2013||Bed leveling assist tool printed and built.||Norm|
|April 8, 2013||Belts retensioned, new bearing endcaps installed to reduce backlash further.||Norm|
|April 6, 2013||Z axis calibration fixed, Z steps/mm in new profile on Git.
X/Y axis backlash observed, infill not meeting walls, delamination observed.
|March 31, 2013||Z axis calibration issues observed.
25mm Test cube showed ~6.8% Z axis error.
