My go to Ender 5 Update to Duet2 WiFi
Steps to remove the old control board and move to duet. The New electronics were not going to fit under the machine so I just put it all on top of the bottom electronics bay
First I'll start with a mistake, the power supply on the ender looked kinda weak so I had a more robust one laying around, after setting up the wires and starting some tests the bed wouldn't heat to full cal temp
I ran M303 H0 S60 for the bed to calibrate
I realized the power supply i chose was 12 volt, the ender being 24. so back to the ender supply. Also I used an external MOSFET to take the power for bed heat off the duet. the duet will run on either 12 or 24 volt
The ender had a great bed level system from uptanium but they no longer are on line or responding.
I installed bl touch, primarily because i have it installed in all my other systems and i have learned the hookup
The online config program has the bl touch as an option so its pretty easy https://configtool.reprapfirmware.org/
It took a couple attempts to get a complete print, it's not pretty but it has a purpose. I build raspberry pi security systems and print a stand for the 7in pi touch screen.
This image is a classic bed level issue, there are previous posts with a similar look. I't about setting up the initial hot end gap

to review: I installed the duet2 wifi on top of the ender control box, removing the ender power supply and securing it also to the top. I installed Bltouch sensor
updated the firmware https://github.com/Duet3D/RepRapFirmware/tree/3.4-dev
did several bed level runs
ran heater cals
changed out the heater element and temp sensor also the tubing, still using the original design hotend
Now the system in online and I can manage it with my other printers using my computer terminal
In the end i have a printer that was in the corner gathering dust back online, it produced alot of products and has made some close tolerance stuff, it's a real workhorse and very dependable, of course it's got a duet now.
one last thing the additional component is a bed heat power module MOSFET allows for the current to be removed from the main board
With everything in-place and a few prints completed (4) "T" fittings for some home made landing gear for a RC project, I decided to move the unit out to the production shop.
Then the big shocker, a different wireless extender, a different "NAME"
I was a little deflated because I was ready to do some production runs and now this setting, one that I normally dred because your hooking up the computer to the duet and sending a specific instruction, and I mean specific. When I first started with the wifi I got stuck because the quotations marks have to be correct or the board wont recognize the instruction. Here goes, time to refresh my brain
Windows laptop with YAT, prey the serial com port is found and connects "YES"
Now the command (I typed in YAT in the search on forum nain page and got the instruction)
M587 S"your-network-ssid" P"your-network-password" COPY and paste this, quotation marks will mess this command up COPY-EDIT-Paste
there are other m codes for the wifi do the YAT search
