Bumped to Marlin 1.1.8.
This version enables LINEAR_ADVANCE for much improved high speed printing. Slic3r Prusa Edition 1.38.5 supports this nicely. There is a "Printrbot Simple.ini" in the directory that works with Slic3r PE 1.38.5.

Fixed the led code, it now works. If you are using a camera, you will get much better results with the led strip mounted at the camera rather than by the hotend. This allows you to run "lights-out" and monitor/timelapse through OctoPrint.
Great strides have been made in Marlin firmware over the years, unfortunately for most the code is a quilt-work of patches and very difficult to enhance. That is probably why there have been so many forks that did something interesting and then fell by the wayside as the patches became tedious to roll back into newer versions.
I have been enhancing/patching the latest Marlin for over a year to allow me to use the latest versions in conjunction with new features of Marlin and the PrintrBot Simple.
The code:
- Linear bed level with triple touch probing (it averages the three taps just like Prusa firmware)
M851 (Marlin standard) is used to set the z-probe offset
M420 can be used to set a z fade height at which bed leveling code it no longer active
X-axis upgrade is supported
Super-Z upgrade is supported
Four-start 8mm z-rod is supported
16T and 20T stepper pulleys are supported
PrintrBot RGBW led strip is supported (using the pins documented in the "official" upgrade process)
temperature controlled hot-end fan is supported (requires you to construct a MOSFET extension board)
Minimum requirements:
- Ubis 13S hotend
heated bed
LCD display is not supported (does not fit in current Marlin memory footprint)
Firmwares are available here (32 builds to handle the various options):
