Thanks again everyone!

@Nxt-1 Thats comforting. That is about the length my wiring is from board/supply to effector. Right now I am just dealing with a strange height map that I cannot diagnose after literally tearing apart my printer and reseating every bolt but thats for another post. I cannot state enough how much I appreciate you guys helping everyone out here. Thank you!

@claustro not sure if applicable but a YouTuber was having the exact same problem with a different printing software and found that it was the resume after power loss feature causing the issue. Maybe give this a look? Video here about their problem

@OwenD Knew it was something dumb. Much appreciated!

@sneakyferret Now to fight the never ending fight of drum roll bed level mesh compensation! Love you guys.

@sneakyferret One thing I have recently noticed: When doing a mesh calibration run, some coords the smart effector makes a very audible but normal 'tap' sound as it contacts. Other spots, its either very muffled (like its tapping cloth) or not audible at all. THE PLOT THICKENS.

@o_lampe Interesting development. I did what you said and identified a single rod that was more loose than all the others. I swapped them around, no difference. Turns out, its that rod position that is more loose no matter which rod is in that place.

@Phaedrux Actually that article you listed very well may be the correction I need. I will make these adjustments and see if it sticks. Thanks!

I see there is M552 S1 in my config, silly me. Mainly, what I was doing was accessing the printer through USB to give it the command
M588 S"*" (to delete all known networks)
then using
M552 S0 (networking idle mode)
M589 S"TallBoyPrinter" P"Kaoken123" I192.168.10.1 (To set it to AP mode and assign it a static IP)
then
M552 S2 (to set it as access point)
I will then disconnect USB and power the printer
But, like you showed me, I think that was all for nothing since the other M552 command is in config. Do I just need to set M552 S2 in my config instead?

Hi. I have a Duet2 wifi I would like to run in AP mode. When I connect via USB, delete its known networks, swap it to AP mode and assign it an IP to use it will not hold these settings when I try to start up printer. It always reverts back to my old wifi network and seems to always remember it even when I clear the known networks. Suggestions? Can post any configs you need. Firmware installed is currently the latest stable, 3.4.6.

Hello! I have worked hard to configure my Duet2 wifi printer and have it printing effectively. I have a question though.

I received this printer from someone and it had VERY old firmware on it. When I was much dumber about this, I upgraded it from a 2.x version to 3.4.4 when I was much less educated about the entire Duet3D system. Basically, I want to install the newest firmware available on a new SD card, update all of the firmware on my board, then transfer over the configs and such that make my printer run like it should. This section took me so long to figure out back in the day and I don't want to lose it.

I have a hard copy of my old firmware backed up just in case but what files need transferring from old install to fresh install so my 3D printer runs? I am assuming the config.g, bed.g, homedelta.g. Is there anything else I am missing?

@leprint Funny you should mention that because I have adjusted the tension and lubricated these things many times but what I find curious is the height map DOES change when I adjust the tension of any of them. I have made a spreadsheet of how I adjusted each tower and recorded the height map afterwards. Then, I would save that height map screenshot, adjust another tower, then record the results to see if I could find out what's causing it but I could never find a clear answer for the cause of those dips and peaks you see in the heightmap. I even lubricated the channels they move up and down through and made sure every bearing was not seizing or clicking with no avail.

@leprint I'll give these suggestions a go when I return home from work. The cables are long enough to not cause pull on the effector when fully at the bottom and they don't sag to much off the side to cause tilt so far as I can tell. I will rewire the effector data cables but all I have is Cat6e. Think that's shielded enough?

I appreciate the tip with getting a proper z level but unfortunately I have already done this about 3 or 4 times with no change in behavior. Thank you for reaching out. I really don't want to get rid of this.

@Surgikill It has load detection so the entire effector detected when it makes contact with the bed.
