Heh, I guess so. Weird. I thought I updated everything correctly when I set this up a week ago, but I guess the DWC is still ancient.

Stand by...

DWC 2.1.0
Board: Duet 3 MB6HC (MB6HC)
Firmware: RepRapFirmware for Duet 3 MB6HC 3.1.1 (2020-05-19b2)

Question about the progress displays.

In the attached screenshot, the red boxes highlight what seems to be a bug. The layer count shows we're at 520 of 894, but the Layer Chart is only updated through Layer 273. Any thoughts on why that might be and/or if it really is a bug?

Howdy!

Quick question for the experts. If I'm using M556 to tune out the last bit of axis error, when and how does this affect the global coordinate space of the printer?

Particularly, I'm wondering if I need to do things in a particular order so that a probed bed mesh registers properly to the compensated coordinate space?

I realize this should be a pretty insignificant factor given the relatively minor adjustments that the M556 are going to make and the coarse probing grids used for mesh compensation, but I find understanding little things like this create great insight into how a system works

Thanks,

Fair enough...

After reading this:

And looking at this:

I had to figure out where to connect the wires.

For the positive leg, V_OULCn clearly maps to the V_OUTLC1 pins in the picture. That said there's a typo. The doc should read V_OUTLCn not V_OULCn.

I was confused about the ground leg. The text "OUT_n_NEG pin (-ve)" from the doc doesn't map to specific text in the drawing. The closest looking one is OUT 6 GND so I went with that. If the doc read that it should go to outn it would be clearer.

@bearer Ah HA!

If someone who edits the docs is watching, I found the description to be super confusing...

Hello!

I'm trying to get my fans (hot end and layer) working for my new build and can't figure it out. This is for a Duet3 so the docs still seem a bit thin.

They're both 2 wire fans, connected to the top two pins of OUT4 and OUT5. (GND and V_OUTLC1) This is what I understood to be correct from the following instructions on the Duet3 Wiring Guide:

4-pin KK connectors with offset spigot OUT_4 thru OUT_6: these are intended for PWM-controllable fans. The connector fits a standard PC-type 4-pin PWM fan. Alternatively, a 2-pin fan may be connected between the V_OULCn pin (+ve) and the OUT_n_NEG pin (-ve).

The fans come on, but they're always at 100% and I can't get them to turn off or modulate the speed at all.

Any thoughts?

Here's my config:

; Fans
M950 F0 C"out5" ;Hotend fan on "out5" connector
M106 P0 S255 H1 T50 ;enable thermostatic mode for hotend fan
M950 F1 C"out4" ;Layer fan on "out4" connector
M106 P1 S0 ;Layer Fan

@Phaedrux Ok. I'll look around. I've googled a bunch and I'm having a hard time figuring out the difference between P5 and P8. Filtered vs. Unfiltered isn't a distinction I understand intuitively, and that's the extent of the distinction in the docs I've found. How are these functionally different?

Interesting. I was focusing on the config instructions from PrecisionPiezo which indicate that one should use Type1 for an analog setup, so I'm not sure quite what to read into that. The board has both an analog and a digital output...

Well, I got it working. I had to convert from the analog probe type to digital, but now it's all good.

Not at all sure why it wasn't working in analog mode, but whatever.
