Duet 2 Maestro + Quadfusion Dev Here: Halp?

streamliner

Just an FYI -- 4 of my drivers are being used to drive my extruder, if that looks odd =P

Phaedrux

2560 for the z axis steps per mm definitely looks weird.

I'll take a look at the rest and get back to you shortly.

Phaedrux

Also you don't have a z Endstop defined at all.

Phaedrux

; Endstops
M574 X1 Y1 S0 ; Set active low endstops

Add a z1 in there and comment out the m558 command below that.

I just located this in the original Ender3 firmware; the value was way off for me too... looks like it should be closer to 400. I'm trying that now.

streamliner

Okay.. .things are getting better; but it's still like my Z-axis is inverted... plus, it doesn't respond normally to the endstop being activated. Here's the updated files: 4_1533094853578_homez.g 3_1533094853578_homey.g 2_1533094853578_homex.g 1_1533094853578_homeall.g 0_1533094853578_config.g

SEems like there's a bug that prevents Z from going into the list of endstops, this was after using the configurator again.

To correct the direction its a simple fix, Im guessing your Z drive is P2 like the duet. In that case change the
M569 P2 S1

To
M569 P2 S0

What kind of endstop are you using?

streamliner

I am utilizing the stock creality endstops for the cr-10, have them wired correctly but i think i've found the problem.. just gonna reverse diretiion of z.

pogo1213

when the endstop triggered, how did the machine react? continue as if it wasnt triggered or did something else happen. Also was this happening when you home all the the axis interdependently? or did you hit home all? The configurator tends to royally screw up the Homeall.g file

streamliner

So, after making the change to Z's direction, everything seems to be going nicely. Now it's time to mount the CMYK head and see about some full color printing. I altered my original plate(not in a way hat would prevent it from functioning in teh stock config.. just two holes w/ some standoffs). Heeeere we go.

streamliner

Thanks guys -- will report back with results.

Phaedrux

Awesome. Glad it's working out. Can't wait to see what the quad head can do. Very exciting tech.

streamliner

Me too! In addition, we will be holding our first AMF meeting this Friday to discuss an open color standard. So many excited things on the horizon; I am really glad to see the duet community is so helpful and healthy; the same can't be said for most... we strive for this in Klipper as well. I will definetely keep everyone updated as to the results and progress we make as we continue to flesh out true color mixing.

streamliner

And by the way Phaedrux; looks like that Z-endstop issue is a bug with teh configurator.. no matter how I defined my settings(Even going back to ensure it was set, after the probe section was completed) it would not include Z as an endstop... is there an easy way to mark this as a bug on the website, or just do it on github? Thanks again for your help.

Phaedrux

You're right about the configurator. I think this may be a known issue.

To get it to add a Z endstop I had to select Switch, and then for the end stop type either active high or active low, which gave me:

; Endstops
M574 X1 Y2 Z1 S0               ; Set active low endstops

; Z-Probe
M558 P5 H5 F120 T6000          ; Set Z probe type to switch and the dive height + speeds
G31 P600 X0 Y0 Z2.5            ; Set Z probe trigger value, offset and trigger height
M557 X15:215 Y15:195 S20       ; Define mesh grid

and

; homeall.g

G91                    ; relative positioning
G1 Z5 F6000 S2         ; lift Z relative to current position
G1 S1 X-235 Y215 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 X5 Y-5 F6000        ; go back a few mm
G1 S1 X-235 Y215 F360  ; move slowly to X and Y axis endstops once more (second pass)
G1 S1 Z-205 F1800 S1   ; move Z down stopping at the endstop
G90                    ; absolute positioning
G92 Z2.5               ; set new Z position
;G1 Z5 F100 S2         ; uncomment this line to lift the nozzle after homing

And that's using a switch as a z probe not as a simple endstop. Selecting no probe should add the Z parameter to M574.

You are right, there is a bug in the configurator. I'll get it fixed.

@streamliner For what it's worth, I've been using various Diamond 3 colour and 5 colour mixing hot ends for a couple of years or so and I've had a couple of email conversation with Michael Armani but he seems to have everything covered. I'm also an early adopter of Duet boards. I don't have a quad extruder to play with (my pension won't stretch that far) but there might be some Diamond related stuff in my blog https://somei3deas.wordpress.com/blog/ that might read across to the quad. Also, feel free to PM me if you like.

streamliner

Thanks guys -- i'm actually good to go at this point; head is mounted.. i'm making some fan brackets, and we'll see how it goes.

@dc42 thankyou Sir; just so ya know, I tried going in a few different ways and defining my z probe to none/configuring my endstop settings in a number of different orders and ended up getting the same result. Seems like it's jut carrying those values over.

@deckingman I would love to speak with you for a number of reasons... one of those being the upcoming AMF discussions. First call is on Friday; were you going to be on that call @dc42?

Thanks again guys, time to finish this thing up.

No, I am not aware of any discussions about AMF. Who is involved?

Hey All -- I hope that you're all well. Well, it was a bit arduous tracking down all the parts, making the required modifications, etc... but I now have a fully mounted, strain relieved, quadfusion head. The single thing that is not functional at this moment are my part cooling fans, and I believe it is simply a misunderstanding on my part, and, well.... everyone else working on this project.

In the QuadFusion setup, the concept requires one central always on heatsink cooling fan, and two side mounted part cooling fans... the configuration M3D currently has on GitHub, however, simply does not make sense or seem to work as it should. Here's the Fan Section:

; Fans
M106 P0 S0.3 I0 F500 H-1 ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
M106 P1 S1 I0 F500 H1 T45 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on
M106 P2 S1 I0 F500 H1 T45 ; Set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned on

I have searched the documentation, attempted to understand the purpose of this, and how it works for them.... i'm starting to think perhaps something just hasn't been updated.

Here's the way I would like to set up my fans:

I have two 24v part cooling fans plugged in to Fan0 and Fan1; I would like for these to be controlled with gcode commands. I have my heatsink fan on the Always On Fan port. Everything is set for 24V.

Here are a few things I notice:

The Always On Fan doesn't actually come on unless I turn the heater on and wait about 10-15 seconds. The part cooling fans do not respond to gcode; I had planned to control with gcode, as mentioned above, but... I honestly am not sure what's going on. I have checked and re-checked my wiring. Any ideas?
