After a lot of work i’ve finished Version 1.0 of my STLViewer plugin for WordPress. You can download it at wordpress.org or update it in your WordPress installation.
Since my drawing skills are very limited and easter is approaching at high speed i decided to build a SphereBot. First i thought about ordering the EggBot but it wasn’t available for a long time at Watterott.com (now it is :-D).
The CEO at my student job turned 70. Having a 3D printer & scanner at work there was only one thing to do: make candles.
Take some LED strips, cables and an ULN2803 and you get a nice light setup for your Ultimaker (or 3D printer in general). The inputs of the ULN are wired to the PWM outputs 8,9 and 10.
With the normal Marlin firmware you can control the PWM value with the M42 command.
M42 P8 S255
This sets the output 8 to full power. That’s all!
