Hi,
Help. I have a SV08 Max from your original kickstarter.
The last thing I printed with was PETG. Now I’m receiving “!!failed calibration - frequency not increasing each step” when homing the Z.
I think the heat (nozzle 230c plate 80c) may have damaged the Eddy sensor or distorted the plastic housing.
Now during the z homing it seems to attempt to push through the plate, slightly rotating the toolhead on the belt. You can see this in the video link.
I have some photos and video. Imgur: The magic of the Internet
I’ve performed a factory reset, incase it was a setting problem, but the initial calibration still errors the same.
Can you help please?
If the problem has not yet been resolved, after examination of the video and photo suggests that the eddy current sensor housing is damaged—or rather, deformed and tilted. It would be advisable to check this first and attempt to recalibrate it to factory settings.
