Using two extruders on a long Bowden tube one assisting the other…

I just see something like PLA fracturing in that drag chain setup…..........

Absolutely. Slightly aged translucent PLA is an absolute bugger for doing that, even with my 250mm long Bowden tubes. It goes really brittle and breaks with the slightest provocation so I'd say the OP will have absolutely no chance of printing translucent PLAs. (Just my personal opinion you understand - no offence meant).

I would add in any aged PLA, Something that you can get away with using a direct or short bowden that would just never work with the drag chains.

Good news guys its all working fine now noticed small break in the wire on the cheap motor thanks to tony for that ! also found that i needed to change the 100:100 on the mix ratio to 1:1 for correct proportions i.e. it extruded a meter instead of say 10mm printed 100x that or something along that line but all seams well
and as for the brittle filament i will cross that bridge if it proves an issue thanks for the heads up i made sure the bend radius was not crazy for the hole run

Awesome, hope everything works out really well.

Below are pictures of the first layers am i over extruding ? also what hight do you guys recomend from the bed with a 1.2mm nozzle ?

It looks like you are under extruding more than anything else.
Layer height 0.6 to 0.8 for a 1.2 nozzle. I tried 0.3 but that was not a success.Can you do a test to see what kind of force is needed to pull the filament through the bowden tube? I use a hanging fish scale to measure pulling force. We can get 5 to 6 kilo's of pulling force.
What is the temp you need inside the chamber?

figured as much was confused that cura spat out 1.2mm but i then realised i entered it into the wrong config tab… felt by hand yesterday pinching with fingers and couldn't really stop it
and basically after consistency more than anything hot maybe 30 deg..

one other thing why dose the ip dress change every day is there a way to make it fixed ?

You can probably get your router to always assign the same IP address to the DuetWifi. Have a look at your router manual, it's often called a DHCP reservation.
Manual IP address setting is on the firmware wishlist.

I'm surprised that the IP address keeps changing. I've had 3 Duet WiFi boards on my network, and my router always assigns them the same addresses. I think most routers work this way, they remember the last several MAC addresses that connected to them so that they can give then the same IP address when they reappear.
