da Vinci Duo 2.0 Extruder Problems

Why would I do that? I don't have any reason to have two extruders if I was only gonna use the lower one. This machine is brand new too so it shouldn't be having this problem right? Is it possible that the first extruder is broken and dispensing irregular portions of the filament and making each layer stand too high? I can't tell.

I don't think you understood me. When you do a dual color print, the software considers one extruder the primary, and one the secondary. When you plan or design a dual color print you design it so the first color to be laid down will be done by the primary extruder which will be the lower of the two. All dual extruder printers are designed this way. It is up to the operator to setup the software and load the correct extruder so the first color to be printed will be from the lower extruder.

By setting it up this way the secondary head can still print but won't hit the previous layer that the primary head puts down.

All you need to know is the printer will print the perimeters first and then the infill so plan accordingly.

The other thing to keep in mind is many don't buy a dual extruder for two colors. They buy it so the second extruder will use HIPS or PVA filament for supports which can bee dissolved in water if PVA and some sort of citrus based solvent if HIPS.

Have you adjusted your bed properly? By properly we don't mean the built in auto method. It is defective and sets the wrong height.

By properly we mean the manual method that can be found in the XYZ section.

Their manual says it does not need to be adjusted but I and many others can tell you that is not true.

Put it over the glass just in front or behind the metal tabs depending on your position. Don't run the auto method after doing the manual procedure.

it's really not an alternate method. Until very recently when some machine began to have an auto feature, this was the ONLY way to level beds. So far to date it is still the most reliable.

You should just feel a gentle drag, but yes the gap is officially supposed to be between .15 and .2mm as measured with a feeler gauge. Many don't have one so the paper is the next best thing. You want a very squished first layer to assure adherence to the bed with glue.

Also as with many of the XYZ machine your bed may be warped. It may be higher or lower in the middle than the edges so you may have to meet a happy medium if it is.

If you read through the XYZ section you will see the issues with their machines. The first thing you will want to do is get 3mm tempered glass cut to put over the existing glass be fore it starts chipping and that will also help with the warping if yours has it.

The temp will be same, it will just take a few minutes longer to heat since the glass is thicker now. Glass is an excellent thermal conductor.
