I didn't find stuff to insulate the Lite6. But after 2 hours running at 210°C, the top part of the heatsink (groove mount?) was still cold! So, I will re-designed a support without all the fan duct, in order to print real things (the above test was just extrusion in the air), and see if the print remains correct.
I also ordered these connectors: . I will drill a custom heater block, with a metal

QuoteUsing a PTFE liner reduces this friction and insulates the filament from the heat that does pass through the heatbreak
So, the heatsinkbreak tends to heat up the filament, not to cool it down! That's exactly what I said before. So, removing the heatsinkbreak, and have fresh air on the PTFE can only improve things.
Ok, I launched the test without fan on the heatsink: so far (almost an hour

No, the Lite6 does not have heatbreak! Your are describing the E3Dv6 standard... The Lite6 heatsink is screwed directly on the heat block, and touches the nozzle. Then, the PTFE tube goes down to the nozzle too. I own a Lite6, so I'm sure of that.
That's why the Lite6 is limited to 250°C, where the E3Dv6 can go up to 300°C or more, because the PTFE never reaches that temperature, thanks to t

You say that heatsink conducts much better than the air. I agree. So, it is also directly heated by the nozzle, because of the direct contact with it! Plus, PTFE is a good thermal insulator; so how can the heatsink cool down the filament? Don't forget that I'm talking about the Lite6 version, where there is no heatbreak inside the heatsink... and this Diamond version works fine.
Look at this hot

About the heatstink and mount, I'm thinking to something very simple, with screws and large washers...

As the heatsink arround PTFE is hotter than ambiant air, I don't see how it can cool down the filament better than ambiant air...

Hi!
I plan to use a Diamond hotend (3 or 5 colors) in Lite6 config.
I'm wondering: are 3 (5) heatsinks really needed ? As PTFE tubing goes to the Diamond, what about making a custom heatsink (don't know yet how), in order to attach the Diamond on the carriage, and put the (all metal) pushfits directly on the Diamond?
Thanks,

Yes, the rail mounts are screwed using the BBB holes. The fan mount is just plugged on the Replicape dual row connectors.
BBB + Replicape: 120x80x30mm
BBB + Replicape + fan + DIN: 120x80x80mm

Here are the photos.
I confirm, is has a 4Gb MMC.
About shipping cost, it is almost 25€ for USA (only 12€ for Europe). So let's say 100€ for sending it to you. And I include the 4Gb micro-SD card.

As said, I will need more drivers in the future. Better buy the Duetx2 now, and do a smooth upgrade if needed; it may not be available in a few months/years (because of new boards).

Hi!
I'm about to order my Duet wifi. To implement my 4 axis setup, I will need an additional motor driver. So, a Duetx2 is enough. On the other hand, I think I will switch to an active mixing hotend, as soon as a good one is out. So, more motors drivers will be needed.
Is it possible to upgrade a Duetx2 to a Duetx5 later? Do they share the same PCB? Do I only need to solder the connectors, TMC

Does the support for mixing extruder support active mixing?

Is it possible to route the DueX5 fans outputs as main PLA fan, and as hotend heatsink fan?
Do you know when DueX5 boards will be available?

Hi!
If I power up the Duet with 24V, do I need to use 24V fans? Or is there an onboard DC/DC conversion to 12V?
Thanks,

Hi,
I'm building a large CoreXY printer (320x320x320), and its first task will be to print a real size BB-8.
The body will be build from a big PMMA sphere (or maybe stainless steel if I can find one), and 3D printed panels will be screwed on it. For these panels, which are parts of a sphere, I would like to make something smart: instead of print them with a lot of support, I would like to print

Hi!
I plan to buy a Duet wifi for my upcoming CoreXY printer. I may be able to put my hands on a 14" 1024x768 touch screen, connected to a PC; is the web interface usable on such screen? Should it be used through the mobile view, or is it ok to use the standard PC view? In this last case, are all widget displayed on the screen, or does it need to scroll to see some?
Thanks.

I see. Are PU belts always white? As Stratasys belts are black, I think they are neoprene+fiber glass core... I will use such belts.
Thanks.
BTW, I did take thickness into account to perfectly align my idlers pulleys...
