- Upgraded to Stepstruder after DC motor died after 4 days.
- Using ScribbleJ's MK5 Wades because the delrin plug was terrible with quick filament reversal.
Blue Prusa Mendel
This started out as an experiment to build a Prusa frame because I could print the parts and get the hardware for free from Ace Hardware (using Discover Card cash back bonus translated into Ace gift certificates at 125%). Of course it blossomed into a full printer:
- Printed with the ToM from the git repo adjusted for SAE.
- Makergear hybrid GrooveMount with heatcore hot end and 0.35mm nozzle in 1.75mm configuration. Also have a 0.5mm nozzle but I'm not even sure how you change them ;)
- Filament pushed by the popular Accessible Wades and self-hobbed bolt.
- Gen6 electronics running from a Dell laptop power supply (19.5V) with the firmware modified to reduce the duty cycle to the extruder head to compensate for the stock 6 ohm nichrome.
- Steppers direct from Kysan 42BYGH4803
- Using bronze bushings rather than printed PLA
- Z couplers replaced with beefy ones meant for PLA although I printed them in ABS.
- The 8t T5 pulleys in the git replaced with true XL (0.200") pulleys to match the actual belt! See my discussion in Acquiring Drive Belts
- Eventually with power-resistor heated aluminum bed driven by a custom RS485 board for the Gen6 to talk to.
