I was logging the probe values to troubleshoot first layer issues and noticed that it was fairly inconsistent. I did the nylock mod to try and level the bed as much as possible which was successful. However I have noticed the first layer has been inconsistent from print to print. On some the Z offset is perfect and on others it is too close to the bed. What I did just now was to run the prusa leveling guide through octoprint from just turning the printer on.
I ran the calibration 7 times without adjusting any screws. My bed variance went from .063 to .011 on its own, that would seem to explain why I am seeing inconsistent first layers. The probe seems to be secured tightly.
Does this mean I need to preheat the bed for awhile before kicking off a print? Is anyone else having to do so?
Thanks for your insights!
Hi Mauricio,
I would be more inclined to monitor the Pinda Temperature
Pinda Probe sensitivity changes with temperature,
On the Mk3 Prusa have endeavoured to address this with a thermistor in the probe, and firmware on the einsy.
but there is no guarantee they have got it sorted in all instances.
regards Joan
