Help Needed with Dual Extruder V3

[Optimum]

Hello,

Recently I tried getting a Taz 5 with a Dual Extruder V3 to print with both nozzles successfully. I printed calibration prints in PLA on the individual nozzles to verify they had proper settings, and both came out great (though arguably the left nozzle needs more help).

However, with both nozzles going at once, it's a nightmare. I can't even get the first layer down very well and there seems to be a severe lack of public knowledge for tuning this thing. Could anyone post their profiles or share key tips that got both nozzles working well?

My profile should be attached, but I'm new here and I don't have much faith in these forums' file uploads.
