Hello all,
With your help I have finally gotten my printer to print recognizable shapes! It went from globs to nearly perfect cubes in one night. After months of toil I couldn't believe it. I am so excited I am now looking for upgrades to improve the quality. I have pretty much the standard Prusa Mendel i2. Here is what I have:
Microcontroller: Arduino 2560 Mega w/ Atmega 16u2
Printer Shield: Ramps 1.4 (Sprinter firmware)
Bed: Heated Mk2 - thermistor thermally adhered to the bottom center, Borosilicate plate on the way
Bearings: brass bushings
Hotend: Unknown (someone wanna take a look?)
Extruder: Wades
Drivers: A4988
Power Supply: 630w PC PSU
Endstops: 6x Optosensors
Motors: Nema17
Adhesion: Aquanet hairspray
Currently it will print fairly accurate, but 90 degree angles are not as good as I would like them.
I'm thinking I should definitely upgrade my bearings, but what would you recommend? Also I only have a fan on the printer shield. I see them on hotends, what benefit does this offer?
How about a chamber to hold the heat? I have read that a turkey bag works pretty well. I was thinking of constructing a pvc frame wrapped in turkey bags. Thoughts?
One of my long term goals is to have it remove a print to start the next one.
