@Merlin246 whats wrong with M116? I use that when heating a tool using M568

@gallaghersart as far as i'm aware there was a post about this and Tony said it wasn't possible as so much had changed

@ov_darkness the 1.02 version you can. same with the 3HC

@tkln yes. connect the grounds together between the 2 PSU's.

@Kruix the R value in M569

@Reine it depends what LEDs are used.
If its the spec ones, they can draw a maximum of 150mA per LED, so 13.5A in total

@Reine looks like the don't do an RGBW stick (although they should!)
RGB LEDs typically draw 60mA at max brightness. So 30 per stick and 3 sticks would be 90. This would be a max current draw of 5.4A (27W), which would be slightly above the current draw of your external 5v PSU.

@Reine i'm not sure what controller you mean? the 6HC has built in support for neopixels (both RGB and RGBW).

And with connecting the strips to the 6HC or 24v it really doesn't matter. whats important is the current limit of the output you're using. The white ones can be daisy chained so as long as they're under 6A, it may be better to just use one of the heater outputs

@Reine as far as i know the disco ones are 5v so you would connect them to the neopixel header.
The concern then is current draw and you may need to use an external 5v supply

@Reine yes. the only thing to consider is the maximum current draw.
each LED draws roughly 60ma, so 10 LEDs would be 600ma.
out4 to out9 can handle 2A each so as long as you're under that value you should be ok

@FBG you'll want to use a while loop in daemon.g
https://docs.duet3d.com/en/User_manual/Reference/Gcode_meta_commands#loop
something like

while state.status <> "idle"
  M42 P0 S1
  G4 S2
  M42 P0 S0
  G4 S10

@deadlock how are you setting your Z workplace position? where are you setting 0 to before it starts etc?
these 3 lines (11 to 13) take you down to 0.11mm from Z0

N40 Z15
N45 Z5
N50 G1 Z0.11 F50

@kuon I think the difficulty will come in that the 6XD/HC boards have CAN termination resistors pre-soldered in place.
You may end up having to go the route of 2 x 3HC's

@gloomyandy schematics are here https://github.com/dc42/PanelDue

@oozeBot the fan ports switch to ground. The 5v, 12v and 24v are all from the same source so switch away

@JRCL said in Z-Axis Endstop Faults:

M574 Z1 S2 P"zstop"

This is wrong and should be

M574 Z2 S1 P"zstop

@anthony1m m122 output please as well as your config

@jago yep

@airscapes have a look at btncmd https://plugins.duet3d.com/plugins/BtnCmd.html

@jago you can map 2 outputs to one heater
e.g.

M950 H1 C"3.out0+out2" Q100 T1 ; create heater 1 using ports OUT0 and OUT1 on CAN board 3 (RRF 3.4 or later)

you can also map 2 heaters to 1 tool
e.g.

M563 P0 D0 H1:3 ; create a tool using extruder drives 0 and heaters 1 and 3

you can't join temp sensors together but you could use daemon.g to monitor the second one

@JabawokJayUK what do you class as the latest firmware?
please post an output of M122

@chrishamm this is all running the stock build from github.
There hasn't been any need to build DWC recently

The gcode editor has issues rendering line numbers longer than 9999

@Dennis_kim please don't duplicate post.
