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

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.

Hi,
I'm wondering how to configure the enable pin of a co2 laser. It would be great, if I could trigger an output with the M3 gcode or is it already possible?
Can somebody who uses a duet with a co2 laser share his configuration for the laser?
best,
Vincent

Re: Velocity Ramping

Hi,
Are there any plans when raster clustering will be implemented?
I have a fairly big CO2 laser with duet3 (sbc). Now I have the issue that greyscale engraving is overloading the raspberry pi.

Hi,
I have a similar problem with my blTouch after upgrading to RRF3.3 (Board: Duet wifi 2 ).
I replaced the wiring with a shielded cable, but the issue is still there.

@o_lampe they use a bevelgear

Hi,
I think the two magnetic foils will repel each other, because they have the same polarity.

yes that's the 1:3 reduction with a 60t and a 20t gt2 belt.

M569 P5 S1 T3.5                                  ; physical drive 4 goes forwards
M569 P6 S1 T3.5                                  ; physical drive 4 goes forwards

I set the rigidity of the motors (Parameter P01-03) to 22.

Here are some pics from the printer

and from the final belt reduction gear:

Hi,
Here is a picture of a print before the gear reduction:

And after:


Printspeed was 100 mm/s @20 000 mm/s² acc

Hi,
I can post some pics on friday.

Yes you can connect it directly to the duet board. But I would recommend the expanson board to you, because this has a higher trigger voltage. I also use a 3:1 belt reduction gear because the servomotors are difficult to tweak.(without gear I had salmon skin)
