The 3d printer has been sitting stale for some time with ABS loaded. It was decided that all 3d printers should be in operational state, so a trial print effort to bring the printer out of staleness was attempted. The favorite "low effort" trial print was selected by the operator: chatlowpoly. The following is a list of trial numbers along with the changes made after the print. | |||
# First trial print with chatlowpoly, acceleration set on printer because acceleration noises are cool. The print was only completed until the first layer since a bit of stuff on the nozzle was colliding with the part cooling duct. | |||
#* Default material temperature of 200C good. | |||
#* Operator's chosen 65C bed temperature good. | |||
#* Part cooling too high, reduced to 30% following print. | |||

Introductory Information
Leveling Journey
The IIIP was donated by Jeff after it failed to level for too long after a glass build plate upgrade. It was indeed nonlinear to level even with our best 3d printer technicians.
The old formed sheetmetal base was upgraded to a thick aluminum sheetmetal base and leveling was tried with that. It was still relatively nonlinear to level.
It leveled fine with the glass build plate removed and an adhesive PEI sheet applied. It has remained with the adhesive PEI sheet to this date.
Behind the Name
Since the stylized Monoprice logo (MP) looks like IIIP, this printer is nicknamed the IIIP.
Components
Hotend Journey
The hotend is currently "upgraded" with a chinesium bimetal hotend. There is a stainless steel heatbreak section which is threaded (and locked with JB-weld) onto a copper section where the thermistor cooling is. We do not have formal testing data to show if the heatbreak performs better or worse than the original PTFE-lined hotend. The original PTFE-lined hotend and compatible extruder tip should still be stored in a plastic bag somewhere in the electronics room.
The hotend thermistor was deemed inoperable in late 2021, and the printer was placed onto the makerspace "do not fix" list. The software compensation that was applied to the thermistor had it set so hot that the 3d printer would falsely report hotend overheats. It has since been replaced as part of a creality and IIIP thermistor replacement project in 2022-07-20.

Operators' Log

The 3d printer has been sitting stale for some time with ABS loaded. It was decided that all 3d printers should be in operational state, so a trial print effort to bring the printer out of staleness was attempted. The favorite "low effort" trial print was selected by the operator: chatlowpoly. The following is a list of trial numbers along with the changes made after the print.
- First trial print with chatlowpoly, acceleration set on printer because acceleration noises are cool. The print was only completed until the first layer since a bit of stuff on the nozzle was colliding with the part cooling duct.
- Default material temperature of 200C good.
- Operator's chosen 65C bed temperature good.
- Part cooling too high, reduced to 30% following print.
- Second trial print, completed until very evident Y axis skipping
- acceleration does not work. Disabled.
- printing too fast? Not sure if acceleration caused Y axis skipping or if the speed did.
- Third trial print, successful but shaky.
- Too fast, but did not cause Y axis skipping. 60mm/s infill speed reduced to 50mm/s. First layer speed set to 18mm/s.
- Retraction amount reduced from 6.5mm to 1.5mm. Retraction hop set to 2.0mm.
- Fourth trial print, successful? Operator left after first layer.
- 1.0mm Retraction hop set. 2.0mm is too high...
A final list of parameters that were changed from default should be provided eventually.

A previous qualification print was made after the ADVi3++ firmware was loaded.
A print made on this day has a lot of ringing on the Y axis and hints at bed leveling (bed too low) issues. A re-level is needed.

The way the filament in the dry box is dispensed into the 3d printer seems problematic since there can be high bending stress placed on the filament at the opening of the direct drive extruder. The operator has temporarily solved this with a crude arrangement utilizing available materials to space the dry box above another dry box.
Additionally, the extrusion steps per millimeter multiplier was not calibrated with the 3d printer. This has been remedied. It is set at 97 steps / mm at the time of this note.
The initial layer extrusion needs a slightly higher flow ratio for better initial layer adhesion; this can be applied in Cura.

The IIIP was moved briefly during a time when MAG Laboratory was lent a Form 1 in hopes that the Form 1 could be fixed. Because of this, it was decided that the printer would be due for a delta test print. The operator at the same time wanted to try a new test print, the YACS.

The YZ test completed without note. Although the print did get smaller in size as the print layers increased, a millimeter or less difference was observed which does not constitute reason for applying a print offset or examining the Y axis hardware.
Although there are already three other test prints that are used by MAG Laboratory, a third test print could be beneficial to operational success.
