Thanks for the info on the heated bed PID not being updated through EEPROM. We’ll update the guide to state the need to change the heated bed PID values if updated in the firmware.
An updated link on installing firmware for the TAZ and other printers can be found here: https://ohai-kit.alephobjects.com/group/firmware-flashing/
We’re moving guides out of the original format into an easier guide/assembly documentation system, OHAI-Kit (Open Hardware Assembly Instructions), found here: https://ohai-kit.alephobjects.com
Thanks!
