Duet3 config Frustration

As I had to buy a new BLTouch, I received a v 3.1. is the wiring the same for both versions?

yes. it should work.
one user had to enable 3.3v logic.

BlueDust

@Veti
Does that mean they used the 3.3v instead of the 5v?

Phaedrux

@BlueDust I wouldn't read too much into it. That particular case could have been any number of things.

However, if you find you're having troubles here is the relevant doc from antclabs on how to switch between.

AntLabs says the BLTouch 3.1 is 5v, and don't want to confuse myself any more on this if I don't have to. I was just curious as I remember older BLTouches needed resistors or something to make them work on the Duet boards. The documentation on Antlabs website in relation to Duet seems old and trying to keep this simple as it was on the Duet2Eth as I use a BLTouch 2.2. They seem to change things up often and I don't mind making a mistake and fixing it, but don't want to break anything and have to buy a new one for something dumb I did (like not reading the instructions).

3Pin: Brown (GND), Red (+5V)
Orange (control signal)
2Pin: Black (GND) White (Zmin)

As always. Thanks for the help!

Duet3 is 5v tolerant so you shouldn't need to change anything on either the duet or BLTouch. It's been that way for a long time now. Should be plug and play.

@Phaedrux
Is the GPIO Port # referring to the io#.in? Where the number would match where the BLTouch is plugged in?

M280 P0 S80 ; set 80deg servo position on GPIO port 0

Thanks

I read something on one of the Z Probe M commands and it made me think it was a heater.
Self test works now...

M280 P0 refers to the M950 S0

The pin name refers to the servo control pin and the probe signal input pins.

Did you get it figured out?

BlueDust

@Phaedrux
Yes, I think I figured it out as I can now home the printer, and BLTouch is working. But found another issue, this time with my PanelDue. I am trying to find the max/min places for each tool using the PanelDue and it's not working.

My PanelDue is only updating temp/axis location after reset (of the PanelDue), but appears to stop after I start moving the motors (homing right now). I am guessing it is interference... Controlling the printer always works. Updating current info on the screen is the only thing that stops working.
PanelDue is on 3.2, and Duet3 is on 3.1.

Thanks!

Stick with 1.24 on the Panel for now. Will work better when the Duet is also on 3.2.

BlueDust

@Phaedrux

OK thanks!

Any idea when RepRap 3.2 will be released? I am only looking for a guess.
Sometime this month?

BlueDust

I just wanted to see this new printer print. And guess what, it's printing. But the part fan isn't turning on automatically. I have to turn it on manually. This must be that F setting on the tool I was playing with before but have no idea how to set it... As I can manually turn the fan on, and it turns on, on the correct tool from DWC... I am not sure what to do to fix this at the moment.

BlueDust

Tool part cooling fan is swapped. That is the problem. Where do I make that change?

Post your config.g file [again] and we'll tell you.

@dc42
So I think I fixed it, as it appears to be working right now... Will not know until I print something with the 2nd tool...

Is this is my current gcode.
Looking at this...
M563 P0 S"LeftExtruder" D0 H1 F0:1

Does the 0 and 1 match up with the Pn parameter under the fans? If it does, I am having a hard time understanding what goes to what between the different Gcode commands, as the letters do not match from one to the other. If it's not obvious, I haven't figured out the logic and not able to easily make the connections to different settings in RepRap 3 yet...

The F parameter in M563 matches up with the F parameter in M950 and the P parameter in M106.

@dc42

Thank you!

If I would like to have independent Z motors on a IDEX Cortesian printer for auto bed tramming, would DUET 3 EXPANSION BOARD 3HC, be the correct expansion board to get, or is there another, possibly better option? Is there anything else I would need to make it work?

Phaedrux

How many of the 6 internal drivers are you using?

The 3HC expansion would probably be the best way to add more drivers, unless you wanted to use tool board for the print head and free up a driver that way.

BlueDust

@Phaedrux
I am using all 6.

Left Extruder
Right Extruder
X Axis
U Axis
Y Axis
Z Axis (two motors tied into one driver).
