Software package 3.3beta3 released

@siam Finally managed to get the accelerometer connected... I'm currently using about 3m of USB 3 extension cable and that seems to work ok, was just a lot of pain to wire up...
It looks like shielding is way more effective here than just twisted wire pairs (which I tried before and didn't work on its own)

The SPI frequency is currently 4MHz. I'll try reducing it, that may make it easier to use long cables.

Thanks for looking into this. Is there any advantage to the higher frequency in practical use? If so, maybe offer te higher speeds as an option still?

3.3RC1 will default to 2MHz and allow the frequency to be changed using a new Q parameter on the M955 command.

Thanks all for your great work!
I have updated my BLV Cube with Duet3 and SBC to 3.3beta3 and everything works flawlessly. It is just incredible that the software can support individual configured systems providing first class prints.

I have had a couple of instances of SBC users experiencing issues with the duetpluginservice not running by default, which is preventing 3rd party plugins being installed/run.

Running

sudo systemctl enable duetpluginservice

and rebooting the sbc seems to clear the issue.

Not sure if its the right thing to do or not.

Adding it here by way of feedback.

I see that Duet 2 can now do neopixel LEDs, which is super cool, but how do I wire them up and configure? Which pins should I use?

https://duet3d.dozuki.com/Wiki/Neopixel_and_DotStar_LEDs

Does it support only original Adafruit NeoPixel stripes or other brands of RGBW stripes?

@thedragonlord In the dozuki is written:
Duet 3 MB6HC supports both DotStar and NeoPixel LED strips. Duet 3 Mini supports NeoPixel only. Duet 2 and Duet Maestro do not support these LED strips directly, but you can use an Arduino to interface them to a Duet.

sure but some rows below:

Connecting NeoPixel strips to Duet 2 Wifi or Ethernet
A signal for controlling Neopixel strips can be output on pin 5 of the CONN_LCD connector provided that you do not have external stepper drivers connected to CONN_LCD. The signal level is 3.3V so you need to level shift it to 5V. A non-inverting 74HCT series gate or buffer such as 74HCT08 can be used to do this.

RGB NeoPixels draw up to 60mA per LED. RGBW ones draw up to 80mA per LED. Therefore the Duet cannot provide enough power for an LED strip unless the number of LEDs in the strip is small (for example 16 RGB or 12 RGBW LEDs). For longer strips you must provide external 5V power to the strip.

Any brand using the WS2812B or compatible chips should work.
