Duet 2 Maestro + Quadfusion Dev Here: Halp?



  • ; 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.



  • 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?



  • 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.



  • 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



  • 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.



  • Thanks guys -- will report back with results. 😃



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



  • 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.



  • 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.



  • 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
    ; called to home all axes
    ;
    ; generated by RepRapFirmware Configuration Tool on Tue Jul 31 2018 22:51:04 GMT-0600 (Central Standard Time)
    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.



  • 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?



  • I've found the posts regarding using Fan1 for the hotend and Fan0 for the cooling fan(I tested it with one of the cooling fans). The always-on fan did immediately come on, as opposed to what it normally does; start up a few seconds after the heater begins heating.

    Can anyone please provide some direction on this? It is my last thing to resolve before cmyk color mixing. 😃

    M106 P2 S1 I0 F500 H1 T45 ; Set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned on

    That would make sense if there was 1 part cooling fan connected to Fan0, and two heatsink cooling fans connected to Fan1 and Fan2.

    Perhaps you should connect the two part cooling fans in parallel to the Fan0 output, and the heatsink fan to the Fan1 output.



  • @dc42 That is exactly what I had interpreted it as, it just didn't make sense -- this is not the case for any configuration of the QuadFusion head. In its suggested and only current configuration it uses a single heatsink cooling fan and two part cooling fans. So.... i'm a bit confused on how we got here; this config is in every single configuration file on m3d's github repos at the moment.

    Anyways,

    I managed to figure out my fan problem; after removing the fans section totally my heatsink fan was working but I couldn't control my part cooling fans.... i had to set them with a freq. of 250 to work, for whatever reason... they are 24v creality-branded 40mm slim blowers.

    That said, after I get some rest... the color mixing shall begin. Color Matched CMYK filaments are on their way for baselines as well... this should be fun.

    Thanks again.
