Congratulations, lots of work for a good cause, well done!

@bambam85 Can you post pics of your Benchy? What version of MC are you using? Also what filament are you using?

@cope413 I have not had many issues with the PETG before this, the printer moved to a new office and the MC was upgraded and I have been stuck every since. So not sure where the disconnect is. I am printing with the .93 multiplier right now and we shall see.

Thanks for your response Martin, I have not messed with the esteps which makes this all the more frustrating. I will go through your procedure and see what happens and post the results.

@pverdin Ran the multi-wall test and came up with the following with the default settings:
Wall Thickness: 1.15 - 1.42 - 1.64 - 2.11 - 3.10

The print looks cleaner then the Benchy....

@mpirringer The fan is off, I will use your article and see what I find out.

@cope413 No leaks from the top for the block, everything default but nozzle temp is set to 245 and bed temp is 70.

@mpirringer Thanks for the response, this is PETG, I have not had issues like this before and it's driving me nuts as the printer is essentially unusable like this.

@michael-petitclerc I checked my z-gantry and yes it was offset, corrected, and recalibrated as per the instructions provided. I removed all my tweaks to bridging speed and extruder multiplier and ran another Benchy test, I had high hopes but still looks bad.

Next steps? Replace nozzle? Replace software?

Thank you for the response Michael and I will take a close look at the Z gantry and see if anything is out of alignment. I am not using a ruby nozzle currently as it doesn't seem to play nice the PETG, I have a fairly new brass .4 nozzle in place.
