    there is a problem with the way those heater blocks are wired

    I have had the problem that those wires pull on the heater block, and at high temp printing (280 for HT) the heater block is pulled loose. This is the main reason for a big leak I had some time ago (that was made allot worse by the fact the carbon filament grinded the threads on the heater block and the heat break, making the leak even worse)

    In this case it will happen on the right extruder

    This only happens with one heater block, as the other one is actually being tightened in that case

    Guys ignore the wiring, there have been a lot of changes to the arrangement and routing of the cables with each incremental version of the carriages, so it's all over the place on the development machine.

    I will be starting a new thread soon which will be dedicated to developing the dual x system. it will be the go to point for questions and details. I'll post it to the forum along with the STLs.

    Looking forward to it. I think I have everything required now, or at least it is on order :)

    Which motors are you ordering?

    @Greg Holloway I ordered 2 Titans for Chases dual version however have yet to fit them, will the design accept 2 standard facing Titans or should I sell one and wait for the mirrored version?

    It will work with two standard Titans, you will loose build volume though.

    I thought the 18Ncm would be better even though there were smaller ones on OMC. I don't think these have the JST plugs so I need to decide what to do there.

    I just ordered some cables to be able to make them as long as I need them to get to the upper back of the printer where my connectors are located if they are too short. Then I can just solder them to the connectors...

    So absolutely no chance that you guys wait for any plans/concrete information then :)

    Or even wait to buy the kit off BB so they make some profit on selling the bits?

    BTW how is this going to sort the slightly thorny problem of the nozzle heights which will need to be micron accuracy in two dissimilar moving heads?

    Would it not be better to head in the direction of mixing with a single head rather than go for two separate?

    Could be obvious answers but I'm a bit of a noob.

    Not if you are able to set the Z height for each nozzle separately... Then its perfect... Still no idea if this is supported by Marlin or will be supported by RRF...

    You use the same offset command as current but can specify a Z parameter (Marlin supports it and I think RRF might)

    I hope @dc42 will think of this but regarding his great work with the Duet and all the stuff I think he will for sure...
    That is the main point for me, no adjusting just telling the firmware by leveling which nozzle has what distance from the bed and done...
