I have a taz 5 and recently purchased a dual V3 toolhead. After trying several mulitcolor prints; all of which look horrible, I decided to swap and print my primary from extruder2 and secondary from extruder1. When I did this the printer made spaghetti. Then i noticed that the right hand (extruder2 nozzle) is slightly higher than the lefthand nozzle and when the lefthand nozzle went over and/or across something printed by the right hand nozzle it scrapped it up.
At first I thought the toolhead was defective and the nozzles were not aligned at the factory. But later it dawned on me that if the toolhead was not setting in the cradle level then the same thing could occur. Since the taz6 has automatic bed leveling then maybe the software deals with this, but the taz5 does not. I intend to try and level them better by adjusting the toolhead in the cradle and locking it down. This is however not a very accurate way of doing this.
I should note that right before my last spaghetti incident I had just leveled the bed using a dial indicator mounted in the toolhead mount.
Is the toolhead being slighty tilted really my problem? If so is there some sort of procedure to follow that ensures the nozzles are level with the bed; assuming that are in fact level with each other.
