Duet on PowerSpec 3D Pro (Flashforge) Issues
Hey all, I'm hoping someone here might have some ideas on what I've possibly done wrong.
I have a PowerSpec 3D Pro, which is basically a rebranded clone of the Flashforge Creator Pro from Microcenter. It has a hotend upgrade and I've been printing PETG very well for some time now with good looking prints.
Over the last week, I switched it over to a Duet 2 Wifi board (with a new upgraded PSU and dedicated 5v PSU, aka the works) because the old board is severely lacking and frankly I hate X3G.
I'm running RepRap3 currently and spent the better part of 2 days working out the appropriate config for the printer, using whatever data I could find online (including other RepRap2 config files posted here).
Everything seems to be working as I'd expect except the print quality is not good. I use Simplify3D to slice and created a new printer profile to match the new board. From there I copied forward the rest of the extruder/layer/speed/etc settings from the PowerSpec profile to the new one I created (other than the scripts which obviously weren't compatible).
Dimensionally the parts I've tested are correct but the extrusion seems off. The first layer doesn't seem as thick as it was on the old board and thus far all my infill is awful. The infill seems like it's missing a bunch of filament, either being stringy or rough/blobby in other places. You can see places where infill walls simply do not exist, looking like a rat maze.
I know we're talking about completely different stepper drivers here but would that cause everything I had before to be thrown out the window? Or do I just have something grossly incorrect that is messing it up?
Any help/opinions would be greatly appreciated. Thanks!
Have you done any basic tuning and calibration yet? PID tune the heaters, calibrate the extruder?
I wasn't able to download your file. Can you just copy and paste the text of your config.g into a post?
I have tuned the heaters but I didn't do anything for calibrating the extruders (didn't see that on the wiki pages). Might be difficult with direct drive extruders but I'll see if I can figure something out there.

I did the extruder calibration and it seems a little bit better; went from 96.28 to 99.06 for steps/mm. There is a lot less blobbing and it's more complete for the infill but still not to the level it was with the old board. I've tried printing slower as well but without any change I can discern.
Any other straight forward things to check? Thanks!

Are you sure about the nozzle diameter and is it set correctly in the slicer? Is the slicer set to use 1.75 filament or 2.88? What speed are you trying to print at? What extrusion width are you using? How many times did you do your extruder calibration? Is there excess resistance on the filament path form the spool?
I think I might have figured it out and I'm surprised I didn't notice it before. My cooling duct fan wasn't running at all and when I looked at how S3D was commanding it, it wasn't sending the fan index so it was defaulting to the extruder fan (based on the notes for M106). I fixed that to explicitly call P0 on the M106 command it the blower works now. Since then I haven't seen any imperfections.
I'm guessing between the extruder calibration and the fan that was probably my problems. Thank you @Phaedrux for the help.
