Basic Information: Printer Model: MCU / Printerboard: klippy.log Hi. Im driving crazy with this. Im absolutely new in linux and pi boards, but know about electronics. I’ve asked and searched as much as i could, but not able to make it run, so came here. I connected 4 wires correctly between …

See Measuring Resonances - Klipper documentation The ADXLs are extremely sensitive about the cable. An Ethernet cable Cat 5e is recommended using the wiring as described in wiring

Hi Frst…thanks for answering! I am pretty sure wiring is not the problem. Distance is really short, wires are good quality ones, and they are solded in both boards to avoid false contacts.
