Flickering led on Smart Effector probe

  • There is a flicker on the probe led after updating to firmware 3. This problem I did not have before. I can probe without any problem when the nozzle is cold, as soon as it reaches 190 celsius it starts to flicker and I cant probe(Error: Z probe already triggered at start of probing move). If I jog halfway up the towers (Delta Duet WiFi) the led goes off. I have changed all the cable to rule out the possibility of a bad connection.
    The code is from RRF Config Tool

    ; Z-Probe
    M558 P5 R0.4 C"zprobe.in+zprobe.mod" H5 F1200 T6000 ; set Z probe type to effector and the dive height + speeds
    G31 P500 X0 Y0 Z2.5 ; set Z probe trigger value, offset and trigger height
    M557 R85 S20 ; define mesh grid

    I am fairly sure that is caused by a bad connection, most likely a bad crimp connection in the +3.3V or ground wire to the 8-pin connector, but possibly a bad solder joint on the effector.

  • I had a similar problem, it was fluff on the cooling fan causing imbalance and vibration. Only present when thermostatic fan came on with higher nozzle temp.
