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.
Behind the Name
Since the stylized Monoprice logo 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.
Power Supply
The Wanhao i3 Plus runs 24 volts.
Controller Board
The controller board is the standard wanhao "duplicator i3 plus" v5.1 motherboard. The microstepping drivers are the allegro A4988ET.
It is currently running ADVi3++ version 5.5.0.
LCD Board
The LCD assembly is the DGUS-capable DMT48270M043_02WT.
It is currently running ADVi3++ LCD version 5.5.0.
Operators' Log
Brandon 2022-12-17
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.
