  1. Upgradefor Kossel V250 reduces noise significantly.

    Posted by Norm Brewer on 6th Mar 2017

    I recently upgraded my 2-year old Ultibots Kossel V250 printer with 0.9 degree motors, metal corner brackets, a Duet wifi controller, and UMBEE e3D V6 extruder, all from Ultibots. This upgrade required completely disassembling and rebuilding the printer, so I decided to do it all at once.

    - The metal corners made a significant improvement in stiffness, and I see a lot less vibration in the top of the printer.
    - The UMBEE extruder works great and makes filament changes quick and easy. The E3D extruder coupled with the UMBEE works great and provides a really short filament path in direct drive mode.
    - The Duet Wifi controller is a big improvement over the previous Azteeg mini controller, and coupled with the 0.9 degree motors makes a major reduction in noise. I really like the Duet Wifi mode, and don't miss having an LCD control panel on the printer. I thought I would use the USB connection, but with the WiFi, there is really no need to use USB. I'm using Simplify3D for slicing, and just save and load the gcode files to the Duet Wifi and print from there.


  2. strong motor

    This motor has good holding torque for one with a 0.9 deg step angle. It also runs noticably smoother than 1.8 deg motors.
