Rex:
Show off your i3 prints! All of my photos are of natural PLA printed at around 50mm/s @190-205 C and 0.15 to 0.3mm layers. Here is what I've changed on my machine:
- guide tube for filament
- added vented panel to control box with 40mm fan
- eeprom settings updated with 400steps.. for z, lowered Y accel to 800, jerk to 17, increased z homing speed to 20.. probably more I cant remember.
- glass plate
- x axis bearings reduced to 2 and upgraded to lm8luu size (also shimmed bearing with paper to make them fit TIGHT in bearing blocks)
- x axis bearing blocks trimmed to clear belt. I went ahead and trimmed both of them on both sides to reduce a little mass
- z axis dampers installed
- nuts added to build plate adjustment screws to lock in place
- build plate holes slightly enlarged
- removed x and y axis tension springs and re-tensioned
- increased x axis belt bolt length to 25mm to clear bearing block
Still to do:
- swap out filament drive gear with MK9 style
- add another fan to electronics box
- change part cooling fan duct to plastic for reduced mass
- add angled LCD panel
Here is what I purchased online:
- Dampeners
- O-ring Set
- 40mm Silent Fan
- 300pc Snap Ring Assortment
- 8mm Shaft Collar
- LM8LUU Bearings
- Borosilicate Glass Bed
- Extruder Gear
The snap rings and o-rings were for the X bearing upgrade. The shaft collars are for holding the Z-axis rods vertically when dampers are installed.
