Print Core Height Issue

[oakcreeklibrary 0]

Hello - I was able to print with print core AA with extruder 1, but then when I tried to print the exact same object with print core AA with extruder 2 it gave me the following error message:  " Difference between detected height of both print cores exceeds realistic values."  I would appreciate any advice on what steps I should take to be able to use extruder 2.

 

I did change the print core for extruder 2 from what it came with - the BB - but I didn't think that it needed to be re-calibrated after changing the print core....?  Or am I wrong about that?

 

Thanks again.

Hey @oakcreeklibrary,

 

Which version of the firmware are you running? 
We have a known issue in Firmware 7.0.4 and higher and are working on a fix.

More information about the firmware you can find here. 

Sorry for any inconvenience 😞

Thanks for the response - we have Firmware 7.0.3 running.

 

And just to ask in advance if you say we need to update it - how would I go about it?  Considering that the printer is not hooked up wirelessly.  Thanks!

You can upgrade using a USB flash drive.  But don't do that as apparently you have the best possible version right now.

 

More information on your error as there are 3 possibilities (read paragraphs 1,2,3)

As of today i am also having this issue when printing with the 2nd core as my support both AA, I have levelled and changed both nozzles. I will try the stable firmware instead of the 7.1.3 we are currently using of the 'latest'.

My issue was fixed by re setting the lift switch, not sure how but it seemed to have lost its calibration or it drifted? All good now!
