05 September 2019 Software https://www.thingiverse.com/thing:3846234 09 April 2018 Next project is coming up at https://www.thingiverse.com/thing:2853532 11 December 2016 Making a combination with http://www.thingiverse.com/thing:1959020 First test was done using the program RoboDK (using extruder and slicer) at https://www.youtube.com/watch?v=cr8D-tIDej4 15 November 2016 Demonstration took place in Daarle 05 November 2016 Some drawings were made for calculations. 27 October 2016 Basis 3 ++ and stepperbearing++3 were modified to be 3 mm longer for added tension on the belt. 15 October 2016 First test (slow) can be seen at https://youtu.be/dr5xWXnUljk End stop is located at https://youtu.be/mhxl9LJRP40 To end position is shown at https://youtu.be/JFYiVxJxmZI Repeatability was tested at https://youtu.be/fkK2kdH04Y8 and also at https://youtu.be/UBeEgJHnAOw 21 September 2016 Gears were replaced with a belt drive (see photo). Pulley has 20 teeth GT2, Wheel has 90 teeth GT2 and the belt is 200mm long with 100 teeth GT2. https://www.123-3d.nl/CNC-onderdelen/Mechanica/Pulleys-p12749.html https://www.123-3d.nl/CNC-onderdelen/Mechanica/Riemen-p12750.html Drive ratio is 1:4.5. 11 September 2016 Electronics consist of Arduino Mega 2560 R3 with Ramps 1.4 (with 5 steppers). https://www.thingiverse.com/thing:1765202 05 September 2016 Rotating 3D printing is happening at http://www.thingiverse.com/thing:1754763 Waiting for new electronics Arduino Mega 2560 R3 with Ramps 1.4 (with 5 steppers). 31 August 2016 Three end stops were installed for X,Y and Z axis. 29 August 2016 Adjustable heated printing bed is a must http://www.thingiverse.com/thing:1742523 26 August 2016 Extruder and 3 steppers are up and running. Bed heating and temperature are working properly. Hot end heating and temperature are functioning well. Bowden system is operational. Looking at the position of the three end stops now, have to make an adjustable printing bed. 23 August 2016 First test took place. Brilliant design from Florin Tobler was used http://www.thingiverse.com/make:245587
