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/](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](https://goo.gl/photos/LyMcFTpjJTF1Xsoq9) But whenever I print it I get this: [https://goo.gl/photos/SqtVCJ8tuADih9p66](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. 🙂 ---

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](https://www.lulzbot.com/dual-extruder-calibration-calculator) After getting my new offset values and entering those in I got a great print.
