seperate Z calibration option.

[rebekah_harper 60]

hiya all,

 

I was wondering if it's possible to get the z-calibration option back. 

I have found myself needing to re-calibrate the Z on ext 2 but have to go through the whole process again and again.  I don't know why but for some reason I can't get the height right first time round.  I do all the right steps but always seems off for some reason. 

 

many thanks

I'm not aware of a bug in this regard, but the soon to be released v5.1 firmware has the whole underlying software for the manual and Active Levelling rewritten. I'd wait for this new software and see if levelling got more accurate.

 

Our design goal is that Active Levelling becomes more accurate than what you can achieve by manual levelling. On the larger S5, but also UM3, we have noted that (ambient) temperature changes have an impact and automated levelling before every print is then the way to go.

Hello everyone!

 

I have the same question. )) There is a line in UM3 documentation, about Z-offset calibration for second nozzle, that it can be done separately. But my 'UM3 Extended' simply does not have such option. It would be great to be able to calibrate Z-offset for second nozzle without going through whole 'Manual calibration' process.

 

Thank you,

Oleg

Yeah they took it out.

but I’m seeing a need for it now. 

I found that possibly because ext2 is spring loaded that when you’re trying to find the same pressure on the card that a small amount of it is absorbed by the spring hence it’s slightly lower.
