I went for the Duex2 to hopefully avoid some of the misery that comes with fitting new equipment into that confined space. That being said I have not fitted it yet.
I'm not 100% sure, but I think the Duex5 and Duex2 are both exactly the same size. The only difference is the price (and the components obviously )
Ha! I guess my plan has a fatal flaw.. incidentally my duex2 is quite small. Quite a lot smaller than I expected - which was a nice surprise.
The DueX2 and DueX5 are the same size as the Duet WiFi (123x100mm) but without the protruding WiFi antenna of course. A DueXn and a Duet WiFi or Duet Ethernet can be mounted back-to-back to save space.
After weeks of planning, printing, building and adjusting I can finally say that my IDEX build is ready. This is my setup with the Duet WiFi and the Duex5. I had some difficulties with the fans in combination with the extruders. Because in the past I blew up FAN1 on the Duet WiFi board (shortcut because the wires of the fan touched the hotend and melted the isolation), I had to move some fan connectors to the Duex5. Currently the fan connectors are connected like this: P0 = Print cooling fan of T0 P1 = not used (broken) P2 = not used (maybe broken) P3 = Extruder fan of T1 P4 = Extruder fan of T0 P5 = Print cooling fan of T1 I had the trigger temperatures of the exrtuder fans set like this: M106 P4 S1 I0 F10 H1 T40 ; Trigger hotend 1 (left) fan at 40 C M106 P3 S1 I0 F10 H2 T40 ; Trigger hotend 2 (right)fan at 40 C And the Tools setup like this: ; *** Tool (Extruder) Definitions ; *** Define tool 0 M563 P0 D0 H1 X0 F0:4 ; Define tool 0 (Left extruder) as using drive 0 and heater 1 G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets G10 P0 S0 R0 ; Set tool 0 operating and standby temperatures to zero celsius ; *** Define tool 1 M563 P1 D1 H2 X3 F3:5 ; Define tool 1 (Right extruder) as using drive 1 and heater 2 G10 P1 U-16.35 Y-16.55 Z0 ; Set tool 1 axis offsets G10 P1 S0 R0 ; Set tool 1 operating and standby temperatures to zero celsius If I understand correctly, this will use fan 0 and 4 for T0 and 3 and 5 for T1. The strange thing is, was that when the print cooling fan of T0 was triggered, the hotend fan of T1 would stop. At first I didn't notice this, until extrustion of T1 became irregular because the PTFE tube became clogged. I finally solved the issue by omitting the Fx:y command in the tool definitions (M563). All fans are now functioning as expected. One minor thing to solve is the tfree and tpost behavior. I used the tfree0.g and tpost0.g from the Duet site Code: tfree0.g M83 ; relative extruder movement G1 E-1.5 F3600 ; retract 2mm G91 ; relative axis movement G1 Z3 F500 ; up 3mm G90 ; absolute axis movement G1 S2 X-23 F6000 ; park the X carriage at -23mm Code: tpost0.g M116 P0 ; wait for tool 0 heaters to reach operating temperature M83 ; relative extruder movement G1 E1.5 F3600 ; extrude 1.5mm In line three of tfree0.g the bed is lowered 3mm. Now for some reason the bed would not raise after a tool change, causing the print to start in mid-air. How did the other builders solve this ?
Must be something to do with relative and absolute distances messing up somewhere, perhaps in the slicer scripts? here is my tfree0.g anyway (adjust accordingly for tool1) M83 ; relative extruder movement G1 E-2 F3600 ; retract 2mm G91 ; relative axis movement G1 Z3 F500 ; up 3mm G90 ; absolute axis movement G1 S2 X-23.5 F6000 ; park the X carriage at -23.5mm And the tpost0.g G1 X-5 Y240 F6000 ; move back G1 X78 Y240 F6000 ; move to dock M116 P0 ; wait for tool 0 heaters to reach operating temperature M83 ; relative extruder movement G1 F75 ; set feedrate 75mm/min G1 E10 ; extrude 10mm G1 F50 ; set feedrate 50mm/min G1 E5 ; extrude 5mm G1 F3600 ; set feedrate 3600mm/min G1 E-1.5 ; retract 1.5mm G1 X78 Y200 F6000 ; wiping movement G1 X78 Y240 F6000 ; wiping movement G1 X78 Y200 F6000 ; wiping movement (I have had some strange extruding speeds during prime from time to time, that is why I have extruding speeds in this (does not seem to help anyway) I use no layer change, retraction or tool change script at all in S3D, those tabs are blank Starting script looks like this for now (differs a little if left, right or both heads are used, uncomment suitable lines) (Tool10, 11 and 15 are artifacts I never use) Extruder 4 and extruder 5 are used for standby temps (set them up in temperature tab with temperature identifier 4 and 5) ; BigBox DX Start Script Begin ; relies on M83 (use relative extrusion distances) T-1 M117 Preparing M140 S[bed0_temperature] ; set bed temperature G10 P0 S0 ; G10 P1 S0; G10 P0 R0 ; G10 P1 R0 ; ;G10 P15 R180 S0 ; ;T15 :T-1 ; home G28 G29 S1 G91 ; relative positioning G1 Z5 F360 ; move Z axis by 5mm G90 ; absolute positioning ; move to heating position G1 X78 U329.5 Y200 F6000 G1 X78 U329.5 Y240 F6000 ; heat bed M190 S[bed0_temperature] ; wait for bed temperature ; set tool temperatures G10 P0 S[extruder0_temperature] ; ;G10 P1 S[extruder1_temperature] ; G10 P0 R[extruder4_temperature] ; ;G10 P1 R[extruder5_temperature] ; ;G10 P10 R[extruder0_temperature] S[extruder0_temperature] ; ;G10 P11 R[extruder1_temperature] S[extruder1_temperature] ; ;T1 T0 M117 Print starting ;BigBox Dual Titan Start Script End
I have printed all of the 3d printed parts and the last of the additional bits should be here Monday. Can I make this work with rumba w/ pi and octoprint or should i really make the jump to Duet? Can anyone give me a list of what parts I would need to convert to duet? Thank you!
@Björn : Thanks ! See what I can do with your script to solve my issue. @Jaysen DAYDREAMn : Apart from the DuetWifi and the Duex2 or 5 I would advise to buy a screen also. It makes your life a whole lot easier. Furthermore you need a bracket to mount your boards in the printer. I do remember someone posted stl-files in this thread.
I'm hoping to make this work with Rumba, I've got 90% of the parts printed and ordered. Rumba works with the Bowden IDEX by Greg so I can't see any reason as to why we can't get it to work with this design?
Thank you guys so much.. @Folkert Kaman I will give this a shot with the rumba first as I really like octoprint and the camera. If I end up going with duetwifi and the duetx5 and the 7" panel... do i need the pt100 daughter board?
Finaly I had some time to install Duet3D with t100 board, Duex5, 7" screen and BL touch. Now it's just the matter of cofiguring it all. Anyone in here with simular working setup who don't mind sharing their Duet config files?
Here you are. Be aware that you have to adjust some things (like stepper directions and fan pins). I still have issues with the tfree and tpost files (z-axis won't move down after tool change), hence the extra z-axis-down lines in the tpost files. I know some users have it working without them, so you may have to move them in order to get your machine working.
OK I found them. Did you do something special with extruder wiring? I have the pancake motors. And When I try to extrude they just vibrate. Don't drive at all. :-/
@Westsidee : no, nothing special. Just followed the color code according to the instructions of the Duet Wifi documents. I have one pancake and one motor that is slightly more powerful (for the Volcano).
