Dual Extruder Calibration Squares Issue

Hi everyone, I’m new here. I just received my dual extruder v2 and have been following the instructions here: https://ohai.lulzbot.com/project/dual-extruder-v2-tool-head-installation/accessories/

I’ve made it to step 27 where I’m supposed to print the calibration squares, and have been running into trouble.

I have the print set up like this in CURA with the dual extrusion merge feature: https://goo.gl/photos/LyMcFTpjJTF1Xsoq9

But whenever I print it I get this: https://goo.gl/photos/SqtVCJ8tuADih9p66

It looks like it is ignoring the merge, and I haven’t been able to find a thread covering this issue in the forums. Any idea what I’m missing?

Thanks for your help!

Hmm… definitely looks like it ignored the dual extrusion merge. In the Machine Settings, is Extruder 2 set to -50? I thought it was stated in the installation / setup directions, but couldn’t find it…

Hi kcchen, thanks for your reply!

Offset Y for extruder 2 is set to -50 in the machine settings.

Hmm… well that seems right. I guess the next thing is to go through the dual extrusion print calibration again. The OHAI pages are kind of weird that they jump around sometimes.

I don’t have my printer hooked up to Cura… so its difficult for me to reproduce. Give LB support a call… they got some smart folks there. :slight_smile:

Will do, thank you!

Just in case anyone else has this problem and comes across this post:

Kcchen was right, my issue was in my Y offset. I needed to measure the distances between my two calibration squares and punch them into this calculator provided by lulzbot: https://www.lulzbot.com/dual-extruder-calibration-calculator

After getting my new offset values and entering those in I got a great print.
