I was hoping to get some ideas from the community on how every aligns the height of their dual extruders. I have been using the method described on the wiki to adjust the height but it does not seem to be precise enough. One hot end is always a hair lower and will catch the print. To make matters worse I have been using the PETG for support and since the PLA does not melt to it the lower hot end will pull the PLA off of the print.
Looking for some good ideas on how to solve this.
