I am giving up on the aerostruder for my Taz6. If I go back to the original head will the new firmware update still work well with it?
There is up-to-date firmware for all of the LulzBot tool heads (http://devel.lulzbot.com/software/Marlin/). Just put your original head back on the printer and update the firmware for that head.
What’s wrong with your Aerostruder?
