After too long, I am finally getting decent, usable prints with a Geeetech A20T. I have 3 Prusa Original 3d printers, and they are dialed in, consistently producing models. I got the A20T due to struggles with multi-material printing. I can now print multi-colored prints as well as print models with consistent mixed colors (minimizing the toothpaste effect). Most of the work is with PLA, but ABS and PETG have also succeeded.
Anyways, I was hoping for some suggestions on what would be the best upgrade to try next. The basic setup of the A20T is below. It’s still a bit loud, and I’m going to make silicone molded vibration dampeners for the feet of the printer and stepper motor mounts. All the fans are under individual speed control, and the A20T lives in an enclosure with the power supply outside.
The printer has stock stepper motors, what would be good replacements in hopes of improving print accuracy?
The extruders are upgraded to dual metal gears, but there are probably better ones out there. What are good, reasonably priced extruders?
I have the stock hot end/carriage setup, but stringing is a problem. What is a good replacement? I tried a diamond hot end, but the stringing seemed worse.
Belt drives, pulleys, tensioners are all stock. Anything better?
I like to tinker, optimize, DIY… as long as I have at lease one functional printer. I just finished designing a fan shroud for the A20T, printed it in polycarbonate on one of the Prusa’s, and it seems to be working well. I like soldering, building electronic components, programming, … Eventually, all the fans in the A20T, the enclosure fans, lighting, and air cleaners will be run off a raspberry PICO.
Much thanks in advance for suggestions!
