Hey all,
I don't have a Duet3D printer, but I saw a topic about dual printers here and I wanted to get your guys' opinions on this
I purchased the Sen3D ender IDEX for my Ender 3 Pro so I can dual print. It is able to print successfully but I've been experiencing a consistent problem with it. On layers that only require 1 extruder, the layers are smooth and even, but on layers that require both extruders the layering takes a noticeable dip in smoothness. It's not just cosmetic either, it causes the prints to be weaker overall. I added pictures and circled the comparison between the two
I've tried dual printing with both PLA and PVA supports and I encounter this same problem. I've spent the past couple of months trying to fix this problem, and I've been in a constant dialog with the creator of the IDEX addon trying to fix this, but to no avail so far. So I'm posting this here to see if anyone else knows how to fix this issue. Here's an outline of all the fixes I've tried so far
• Increasing/Decreasing Layer Height (0.05,0.1,0.15 mm)
• Increasing/Decreasing Initial Layer Height
• Printing at different temperatures (200, 205, 210, 215C)
• Changing PLA filament brands
• Decreasing print speed (30mm/s, 40mm/s, 50mm/s)
• Changed Z support distance (0mm to 0.15mm)
• Increased/Decreased Nozzle Retraction distance
• Turned on/off print combing
I haven't seen many posts about this, so I'm wondering if it's a rare problem. Here's a post from another person on duet 3D that had the same topic, but no solution to it

I'm curious to see what your guys thoughts are on this. The issue seems complicated but maybe I'm missing something? Thanks
