thingiverse

Update 08.11.2020 --- DE: To achieve the maximum possible movement area, I have redesigned the lower corners so that the Bulley is turned and no longer needs the underlying plates. See picture. EN: To get the most space to move up and down, I redesigned the corner on the ground. With the "corner-bottom_20.20.1_v2.stl" file, you do not need the washers anymore and must turn the Bulley like shown in the picture. --- Original 25.12.2019 --- DE: A motorized height-adjustable work table for the K40 laser. The motor is located under the axis on the left and everything below the laser zone is free. Aluminum square profile from the hardware store. Operated with an Arduino Nano and A4988 driver on a DIY board and a toggle switch. With closed GT2 belt - tensioned over the motor bracket.
