Ok I took a few months off the 3d printing so I could focus on getting drone pilot rated and it was a big success.

Now I am back and setting up hopefully 6 machines that are going to be lk1 base but with upgrades. 

1   duet wifi control
2   duel z axis
3  auto bed level of some type
4   quick change head assembly ( hotend and extruder as assembly with magnet mounts)
5  all enclosures with exhaust
6  better material management
7 video feeds
8   to be determined


Now to bring things to an update.  I had a complete setup with duet, duel z, paneldue, and bl touch working great. 
then I had to get it all wire tight and installed in a vent box and I shorted the board, This is the second time with the exact short.   

This then is the process of adding a new duet2 wifi from china with the 1.02 firmware    Below are some instruction links I followed   the process I will document  here




This is a difficult update and gets confusing. Especially  from 3.0 to 3.3.  There are 2 files you have to locate.  



When you are up and running the internet interface and try M997 S0 for firmware update you get these file missing errors   

Firstly understand you will have to connect the duet wifi with a USB data cable to get the first updates to the board. If you don't get a connection via serial port change the cable of find another computer. The YAT program has to find the duet board or your going to have to do a complete board erase and use BOSSA 

That gets real tricky and explaining it is difficult. The Duet website does a good job but it's confusing because thet try to instruct with different boards not just the duet wifi. 

I am trying to detail for only the duet2 wifi and configured for longer LK1

you cannot upgrade directly from version 1.x or 2.x firmware to 3.01 or later firmware


For updating your Duet from RRF v1.x to 2.x, see the legacy firmware update instructions. This gets down to reset the board completely with erase. It's a great experience and will take you a couple hours or days to get it humming. 


What I did was to grab 3 new duet2 wifi boards and updated all from 1.2 to 3.3  at the same time  I have a sd card with all the files if i can upload them I will if not just request them

This is my final files and the 2 missing  there should be everything here https://drive.google.com/drive/folders/1bjXCtonZIx33Jcmff43aCxHj6wrugxZC?usp=sharing

m115 to check version

M997 S0  firmware update 

starting the wifi requires uploading a seperate program to the wifi module

start by   turn wifi off, send m587 command string, turn wifi on 

m997 s1  wifi install

m552 s1  start wifi

m552 s0  stop wifi 

(the M587 command is where you tell the wifi your network ssid info.  Look at available wifi and record your ssid   it is imperative you do the semi colon correct or the command will be rejected. do a cut and past if you have to 

make sure your putting the ssid and password inside double quote characters

M302 S1
allows cold extrusion, but that only works if filament is not glued to extruder.

From this point on its alot of configuration stuff. It's not an easy read but it's here for reference and learning

I ran into a real head scratcher losing the extruder. At first I was getting real light plastic coming out. I decided to update the hot end complete and it still was not improved. Turns out it was a weak motor but what an experience, I was about to replace the duet thinking I messed up the driver chips because I installed duel z axis motors. I wanted to be able to independently drive each motor thinking this would be the best way to relly get the bed level. Well it turns out to have been pretty difficult and I never was able to get it to work correctly. I found myself in the end just twisting the second axis screw to level the bed. so much for fancy algorithms and coding. 
I secided to remove the second z motor and go back to the orignal setup and this is when the extruder quit completely. So the duel setup uses the 2nd extruder driver and you have to configure the duet to see it that way, of course you could just plug in the motor into slave mode by removing jumpers but I wanted the complex setup. Removing the motor from the e1 driver confused the system somehow. Just before removing the duet for replacement I added
