Z keeps moving straight offer calibration - SOLVED

[iconicjamie 0]

Hi guys,

I wonder if anyone else has this problem. I can level the bed on my machine, then select a print. The machine heats up and starts but the nozzle on some occasions can be 1.5mm off the bed. It was set a papers thickness during the calibration

It's annoying as I have to calibrate the bed 2 maybe 3 times before it remembers.

have you updated to the latest firmware? there was a bug in the previous versions. the upward movement after triggering the z-stop was not big enough and sometimes it would still be triggered. that would cause the difference in z-stage calibration.

new firmware fixed it
