Hey all,

 

i encounter the following problem on my MK3S (latest firmware):

It seems, that overnight my first layer shifts upwards by about 0.1 mm every night.

So if i just start printing the first layer is not squished at all and i have gaps everywhere. When i adjust it right and the print is finished i start the next print and the nozzle is nearly digging straight into the bed because the first layer is way to low. 

I was thinking about temperature dependency on the PINDA (not heating my flat so its always about 16 °C) and run temperature calibration which didn't help.

Any other suggestions?

 

Happy printing

You can use the PINDA warm-up routine -- technically not required since PINDA v2 was released -- to warm the entire printer provided you don't have a SuperPINDA mounted.

I actually tried warming up the printer a bit - but it seems to need about 20 minutes at least to get a good result. Is that routine built in? Where can i find it?

So i tried heating up the PINDA to 35 °C before printting: Still during the first print the first layer is about 1 layer to high. With consecutive prints the first layer gets perfect...

 

Hoping for some help

 

Best regards
