Their website will tell you what firmware Zerocart work on... I think it's the best thing since sliced bread myself...

I just need to know that the xyzerocart will work with the 1.2.5 firmware, if someone can confirm this for me, I'll buy it immediately

I really prefer not to downgrade the firmware, as the 1.2.5 im using is much better than the 1.1.J that everyone recommends, and I still have yet to see a stable repetier build that I would use.
SO! Im hoping there is a way to simply prevent the eeprom from being updated by the printer, anyone know how this can be done?

I am not aware of a specific way at stock to prevent this from happening (communication). I use XYZZEROCART to reset things and don't need to worry about the counter. There are other re-setters out there as well but the XYZZEROCART was wireless and pretty easy to deal with. I also block XYZ from "phoning" home.

it is easy to reflash the eeprom to 240m then just use whatever you want and run an empty cart. or rewind a spool and put it in your cartridge and run it from the cartridge. if you dont have an arduino to flash the eeprom then order a arduino nano for around $4.00. I just refilled my cart with some pla then programmed the eeprom temps to 190 for extruder and 50 for bed. it only takes a few min to do and is well worth it.
