 After-print care washing is needed for prints from this printer. This consists of a bath of either IPA or similar solvent. A washing tank is recommended to address COSHH concerns.

-**Manufacturer:** Monoprice (The model is a 'FlashForge Creator' clone dated approx 2018, running Makerbot Replicator 2 firmware).\\
-**Source:** Donated to the space, 17/01/2021.\\
-**Summary:** Dual-extruder FDM printer, 2x 2.85mm filament; semi-auto bed-leveling; needs cleaning and lubricating; working, pending light maintenance.
-**State:** Machine powers on, reports temps and demonstrates working endstops on auto-homing. The printer has slightly jerky rod movement and is pretty dirty/dusty from use and storage. Semi-auto bed-levelling test's ok, heaters reach temps with no problems. Prints can be started via USB or via SD card.
-In order to be able to print, the following maintenance steps will be required first:
-  * Rods in need of greasing
-  * surfaces require cleaning
-  * Reel dispensing solution required
-UPDATE 20/01/21: The manual has been located and can be downloaded {{ :projects:maker_architect_13861.pdf |here}}

+**Summary:** Single extruder delta FDM printer; 1.75mm Filament; uses OctoPi; small print area; working but experiences occasional TEMP ERROR and shut-off during print.
-**State:** The machine powers on and prints via wifi using the onboard OctoPi installation. The print area is small due to bed-leveling limitations (printable area drawn on bed itself). Manual 3-point bed-levelling is done using the GUI to position. Fast or fine detail prints are not recommended. The power supply has been repurposed and may need to be replaced.

 In order to be able to print, the following maintenance steps will be required first:
-  * Bed re-levelling
+  * Investigate/fix source of occasional TEMP ERROR shutoff (loose thermistor wiring, at a guess)
+  * Manual bed re-levelling (upgrading to BLtouch-driven autoleveling would be a vast improvement)
   * Source a power supply
+UPDATE 22/01/21: Alternative power supply located. Drop-off at space pending.

+**Location:** Currently stored at a member's home address, boxed and ready for relocation\\
 **Summary:** Space-made with DIY components; 1.75mm Filament, rather hacky; Hothead issues; Working pending head rebuild.
-**State:** Unused for some time and in need of a hot-head rebuild. Previously, the main board (Sanguinoliu 1.3a) failed due to over-heating problems at the PID hot-bed power output. The board's bed power FET has been bypassed with the 5v logic directly driving an external relay for bang-bang bed control. The XYZ mechanics are working but the hothead assembly failed due to it's plastic cracking. A replacement hothead assembly has been printed and new head purchased. The new head is wired in and is awaiting fitting into the replacement head assembly and fixing on to the X-carriage. Manual bed-levelling lacks precision, but is functional.
+**State:** Unused for some time. Head has been recently rebuilt using reprinted carriage head and new hothead [21/03/21].

Manual bed-levelling lacks precision, but is functional. Recommend inverting the leveling bolt/nut and adding a 3d Printed knob to the nut for easier levelling (Like the Ender3).

   * Sourcing of power supply
   * Manual levelling improvements (ideally)

 It would be good for someone to itemise these at some point.
