To add blinky LED status lights to your TAZ you will need the following:
1 Pro Micro - 5V/16MHz ($20)
1 length of RGB Programmable Addressable LED strip
This or similar Buck converter:
The one I have has shorter capacitors, but looks identical otherwise
and the attached firmware (Taz 3 variant, you will need to adjust the zsteps for the 4 and the extruder stuff for the 5) It’s basically the makerstoolworks firmware bits that controll their blinky lights, merged into the TAZ firmware paramaters. There are extensive changes in most of the main files. That includes the main marlin code.h file, the temperature files, addition of the LED files, and changes to configuration and configuration advanced. Also pinout, etc. Please only use the attached firmware as a base to create your own from known good code. You can upload it as is, and it will work, but I’m not taking any responsability if your printer melts. That being said mine has been wokring fine for about a week now.
I’ll post some pictures of the attachment points and wiring harness once I retrieve them from the other camera. I’m also working on an under the Y axis lightbox part. Another advantage is that you can run standard LED lightbars off the same buck converter for a lighted bed if you choose. For now, i’m basically tappnig off the power feed from the 24v power supply to the heated bed Rambo connector. The bed still seems to get plenty of voltage and heats up just as fast. Alternativly you can tap into one of the unused power feeds from the power supply itself, though you will have to add additional pins into the electronics enclosure. Power goes to the buck converter, adjusted to output 5-12v depending on how hot you want to run the chip. It then goes to the Pro Micro board using the standard connection diagram. https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide I’ll post pictures of what pins I have in use on mine later.
