Yea, used multimeter and a screwdriver. Ok, not sure i will bother to change it. At least not in near future. Got the printer to learn, and well. Wanted a large printer if i need to print something big at some point. Nice to have the option. But at this point i rather spend money on a new printer than continue modding this one, voron or something similar looks fun… 😆 I think got the answers in discord a year ago, but didnt have wires. Now, got the wires, but lost the info… Hehe Other than that, didn’t seem that hard at all when i got help on discord.

I managed to run Klipper on my Formbot/Vivedino T-Rex 3. [Profiles-Formbot-T-Rex3.zip](https://klipper.discourse.group/uploads/short-url/2o4PdZW1pLDLwnIjOjmCEr5UE7S.zip) (8.1 KB) There are three profiles: printer-Formbot-T-Rex 3 : is a profile for a regular printer. printer-Formbot-T-Rex 3-uart : is a profile for the use of TMC2209 in [UART mode](https://learn.watterott.com/silentstepstick/pinconfig/tmc2209/). The uart connection is made using the MISO/MOSI connectors on the printer board (SD card isn’t use with Klipper). printer-Formbot-T-Rex 3-all : is the same as the one above with an additional z-axes (stepper\_z1).
