AWESOME job by Ben, really takes the Ender 3 to the next level!
BLV Ender 3 kit with Hiwin Rails
SKR Mini E3 v1.2
2X Noctua NF-A4x10 Fans (Hotend & Motherboard, running off LM2596 Buck convertor dropping the 24v to 12v)
1X Noctua NF-A8 for power supply (running off LM2596 mounted inside lid of custom PSU case)
Capricorn PTFE Bowden Tube
Yellow upgraded springs. (first upgrade, installed when I built the machine for the 1st time)
Trianglelabs BMG Extruder
18 ws2812b "NeoPixel" LEDs... 15 on top and 3 for hotend.
Double Sided Textured PEI Spring Steel Sheet
Trianglelabs E3D V6 - 4.1 bore. (currently using)
Trianglelabs Micro Swiss All-Metal. (saving for rainy day, maybe if I need to print REALLY hot, not good for PLA in my opinion)
Raspberry Pi 3 B+ . (Octoprint)
Logitech C920 webcam
UPDATE 1/15/2020 - Converted to direct drive (Added 17HS4023 "pancake" stepper motor, 5015 fan & motor heat sink)
UPDATE 1/28/2020 - Added TFT 35 E3 Touch Screen Display and X & Y axis belt tensioners.
UPDATE 1/30/2020 - Switched to Trianglelabs E3D V6 Hotend. (4.1 Bore)
UPDATE 2/1 - Switched to Prusa R3 part cooler.
UPDATE 2/6 - Switched to SKR 1.4 instead of E3 1.2. My E3 had a bug where the X motor didn't initialize properly once in awhile. This has much better Neopixel support, sensorless homing without running jumper wires, and auto fan on/off for the hotend. Using this custom case: https://www.thingiverse.com/make:759740
UPDATE 2/11 - Finally completed the Dual Z upgrade (2 drivers, 2 motors) Using gcode G34 for auto Z align, it's pretty slick!
