The dual extruder is still being worked on. ---

I installed the latest 2.x universal firmware as mentioned here. I have a Taz6 with the original single extruder. What should I pick out of the choices? none seem to have the exact e-steps (830) on the back of the tool-head. The closest one is the “Standard” .5mm which has E-steps set to 814. do I just use that or adjust it to 830? ---

Probably best to use the e-steps on the back of the tool-head. Even better would be to run a calibration and use the calculated value. Search this forum for “e-step” and “calibrate” and you should find detailed steps to follow. ---

Is it only Taz 6 for the universal firmware or does it work on Taz 5 also? ---

There doesn’t appear to be a version of universal firmware for the TAZ 5. ---
