@bot So I tried 4 test prints, and it appears that it hasn't helped much, if at all. I tried values: 0.05, .10, .20, .25, and 0.5.. all of which had little impact on the "depth" of the "overextrusion" away from the inner wall.

@burtoogle Yes, infill percentage is set to 25%.. not sure how I can adjust infill for the skin ? I've tested lowering the "Flow" in Cura, down from 100 to 98, then 97, and down to 90… at 90 it was noticeably leaving gaps between the walls and shell, and there was also gaps between the infill layers.

Any other thoughts would be appreciated! Thanks guys!

Hello All,

I use Cura as my slicer… and recently changed out the board in my CR-10 for a Duet WiFi.

Using HatchBox PLA - 1.75, printing at 200C, using stock hot end.

Layers are .4mm, infill 25%, mostly default settings for a 'custom RepRap' printer in Cura. Retraction is set to 5mm, primary speed is 50 mm/s Cura defaults for all speed-subsettings.

Unfortunately, I'm having a weird issue with infill near the walls... https://i.imgur.com/SMDeDAe.jpg

As you can see, the layers are very smooth and properly joined in the middle areas away from the walls, but I am getting some buildup, like signs of over-extrusion, 2-3mm away from the innermost wall.. I can run my nail over it to confirm that it's slightly raised on the outside of each pass.

I've tried doubling the infill wipe distance (.2mm) and lowered the infill overlap from 10% to 5%… and still this occurs. I don't feel as if I am overextruding, given the fact that, if I let this print go, it would build walls and infill well.. I did lower my extrusion by 5%, and while it got a touch better, my infill started showing gaps on the z-axis.

Any help or suggestions would be appreciated!

… I have two boot partitions on my router; so I selected the other partition, which still contains Linksys default firmware.. and it is working brilliantly. DD-WRT is no more... Thank you for your help!

And the struggles continue… since it showed "connected", I attempted to reach the web interface via IP.. no go. I then logged into my router interface and confirmed that there was no connected MAC/IP listed in M122 output. I have tried every combination of WiFI settings I can.. to no avail... the only setting that actually works is "Open" (no security). Something in the ESP8266 module is preventing it from negotiating security correctly. Any thoughts? I also flashed the 1.20+1 firmware, no difference. Any help would be appreciated!

I think I got it!

I'm running a Linksys WRT-3200ACM with DD-WRT… and for some reason the ESP module on the Duet does not agree somehow with the DHCP functionality of it... as soon as I specified optional network parameters it worked almost immediately:

(13:16:21.706) M588 S"Netstorm"
(13:16:21.741) ok
(13:17:33.321) M587 S"Netstorm" P"heyrobfl" I10.0.0.25 J10.0.0.1 N255.255.255.0
(13:17:33.436) ok
(13:17:39.537) M552 S1
(13:17:39.570) ok
(13:17:43.915) Wifi module is connected to access point Netstorm, IP address 10.0.0.25

Thank you for the quick responses on this matter... (and maybe that should be documented in Wiki, in troubleshooting?)... Not sure if this specific issue has been observed here before... just trying to help others who may stumble on this issue. Thank you again!

Hey Guys,

I recently received my Duet3D WiFi to replace the board in my CR-10 printer. Unfortunately, it would not pickup my wireless access point from 12 ft away.. but would from a hotspot on my phone from less than 1 ft away. Having read the warnings about the wifi not working well, if at all, from a metal enclosure, such as the one the CR-10 electronics come in, I decided to make a project this weekend of moving everything to a plastic container entirely… mission successful!

And.... unfortunately, this has not improved connectivity to my Duet3D at all. I still cannot connect to an access point with a -45 dBm signal that's about 12 ft away. (Connection time-outs.) I'm pretty bummed about undergoing this project only to be shot down by what seems like a bad/failing WiFi module/antenna. Any help that can be provided would be greatly appreciated.

I am running the latest version of firmware and WiFi Server (as of Friday evening, anyway).
