Hey there,

since my project is coming to an end, I would like to share some pics of my new large scale idex printer. The print volume is 550x550x500 mm. The printer is equipped with two E3d Hemera extruders which are watercooled with a custom heatsink. That's why I call the beast HYDRA.

The print bed consists of 4 individually adjustable aluminum plates with 230V silicone heaters and embedded high temperature magnets. Due to the separate beds, it is possible to use only one bed for small parts.
In my printers I'm using belt drives (gun tackle) which prove to be reliable and eliminate z wobbling completely (and any noise).
The bed of the HYRDA is moved by two belt drives (on single heatbed printers I'm using only one belt drive).
The printer has linear rails and a housing made of 3mm steel which results in a total weight of well over 100 kg (as I mentioned a real beast).

Here are some close-ups to the z axis and the used belt drive setup:

And some close-ups to the Hemera extruder heads:

The electronics look like this atm (I know a little bit messy

I wanted to ask if someone already has experience with a setup like this and whether it is possible to display all the four bed in the GUI of PanelDue.

Cheers,
Vinz

Hi,
I have built also a plasma cutter with a duet controller.
It works great for simple cuts. I used estlecam and now lightburn.If you want to cut complex shapes you should mention a torch hight control, because of heat-distorsion. If you are using pilot arc torch you have to do the wiring carfully (shielding and grounding) because of EMI

@o_lampe they use a bevelgear

Here is a watercooling mod for hemera I've build for my printer Hydra:

no, that was milled from 7075 aluminum.

Hi,
That are great news.
I have to build an air filtration system first, but then I can beta test it.
I use the duet 3 board without SBC.

Is it possible to create a tool in laser mode?
I want to use a endstop at the high end and the z probe at the low end.
Therefore I want to use G30 S-2 to offset the laser nozzle. But then I need a tool to run the gcode.
The M563 Gcode to define a tool seems not to work.
Or is there a better solution to use the z probe and the endstop?

Hi can I use the Duet 3 with SBC (RaspberryPi) and a connection via USB with another PC simultaneously?

@dc42 Hi,
I had a typo in my config. now it works fine.
Thanks for the great support.

@phaedrux yes I mean the 1xd expansion board

Hi,
Is it possible to connect the bl touch to the xd1 expansion board, or is it not supported?
Best,

@dc42
Since the working area is quite large (1500mm x 600mm) I can't go above 300 mm/min jerk without having excesive vibrations.

@gloomyandy I use the latest 3.4.0 release on a Duet 3 with SBC

Hi,
Meanwhile my co2 laser is working. Thanks for the great support.
I noticed that the laserpower at a contour with many small lines is much lower than with straight lines (see the picture below - the square was cut with the same laserpower as the deer ).
I think a min Power setting for velocity ramping should fix this.
Best,
