I recently upgraded my TAZ 4 from the 2014Q2 firmware to 2014Q3 firmware, and forgot to jot down the EEPROM settings before uploading the latest version to my printer… Now all the prints are coming out off. Ugh.
Could someone post their TAZ 4 EEPROM settings by sending the M503 command to their printer via Printrun/Pronterface?
prstein and Orias, thanks for the posts and all your help! Much appreciated!!
brouhaha, there are some, but not all of the settings are written down on the initial paperwork.
I’ve been playing with the settings, but had to revert back to the older 2014Q2 firmware. For one reason or another I can’t get the latest version to print properly even after calibrating the extruder feed rate. With the newer 2014Q3 firmware, the z-axis isn’t moving up properly so my prints are “squished”. I’ve attached a picture of 2 donuts that I printed. The one that looks normal was printed with the older firmware. The newer one was printed with the new firmware and is about 1/2 the size of the properly printed one.
The Z steps changed going from the Taz 3.2 to the Taz 4. The Taz 4 is the one with the fully supported leadscrews with bearings top ad bottom and aluminum Z couplers. If you happen to have the slightly older 3.2, the new firmware will not have the correct z steps value in it to work with your existing threaded rod. If you have a Z Nut spring instead of the solid leadscrew mount, you might be dealing with something older than a Taz 4.
