As I remember it, I set the standby temp for the PVA material rather low, like 150-160C without retraction still with a generous purge (some 20mm or so).
yeah I gave up I do have a new problem though finally got arround to fixing the cooling fan for the second extruder but I have a hard time to get it to run at anything below 100% I has to do with the settings but I dont understand whats the problem M106 P0 F10 ; found this in another settings file on the form, the speed control does not work without, so I copied it to the second fan: M106 P4 F10 M563 P0 D0 H1 F0:4 But fans do start at 100% but when I lower it, the second fan stops, while the first one keeps running
2-wire brushless fans were not designed to work with PWM. Some do work OK with PWM, others don't. So I suggest you try another brand of fan.
Try this, only the first three fans on duet are variable PWM, the rest are fixed. Hotend fans work fine with fixed PWM ; Fans M106 P0 F10 ; Part cooling fan (P0 is PWM Fan 0 on duet wifi, 10Hz) M106 P1 S255 T45 H1 ; Trigger hotend 1 (left) fan at 45C (P1 is PWM Fan 1 on Duet WiFi) M106 P2 F10 ; Part cooling fan (P2 is PWM Fan 2 on duet wifi, 10Hz) M106 P3 S255 T45 H2 ; Trigger hotend 2 (right) fan at 45C (P3 is PWM Fan 3 on Duex5)
I too have both my hotend fans running at full chat if hotend temperature is over say 45C just like Mark above
Can someone post their duet config filds and S3D profiles ? Keep having troubles with underextrusion and the extruder steppers skipping. Dont understand why
I woul really apriciate the above Keep having print quality issues and im getting more and more lost. Even single extruder prints are failing now
Here are my FFF file and config.g (had to change file ending to .txt to be able to find it i file browser...) There are a cople of old artifacts in those files that could be deleted I guess. I got them originally from Ephemeris and Alex but modified to suit.
thank you there was only 1 real big difference I changed this: M566 X600 Y600 U600 Z30 E20:20 into this: M566 X600 Y600 Z30 U600 E300:300 got the best benchy so far ! mostly clogging up due to retraction, looks like jerk speed was to blame
Hope things gets better, E20 seems to have been way to low, or? I wonder if the order of U and Z axis really matter.
The order of parameters in that command doesn't matter. E jerk mostly affects how much pressure advance you can use before printing slows down.
Going allot better. Was able to print 2 very nice benchies with both extruders, dual benchy coming. Will go back to test scaffold on tuesday Still have some oozing issues during toolchange, but I think thats because of ngen Im not surprised that 1 parameter can cause this many issues I once burned a 20000 euro batch of chocolate because I forgot to change a setting in the PLC. Didnt get fired
Do you use standby temps? It's very easy to do, you should have no problems with oozing at all with a small priming procedure at toolchange.
wow, just read through the whole thread a second time, amazing work here! Working on printing out the parts to convert one of mine now. Just curious tho, I've looked pretty good and never see where Folkert Kaman re-uploaded his version of the extruder carrier for use with the Molex connectors. I seen a post talking about removing the stl for now due to it hitting the case, but never seen where it was re-upped. Folkert, If you uploaded this somewhere would you mind pointing me in the right direction? annnnd by chance did you ever make a version that accepts the volcano?
Thanks for your post Jon! I never followed up the volcano thing, i have those hotends in a box somewhere and it should be doable without significant mods, the original Chase version worked with volcano hotends as I remember and so should this?
I too just read through this entire thread and I'm going to make the move! Folkert Kaman , please upload your carrier mods!
Hey, i tried to configurate the IDEX Version on the BigBox with two Titan Aero Extruders. All the homeing works perfekt, also the heating and the fans. But when i want to start a print, it start with the homeing but then it didn´t heat up and in the WebInterface it says that the print is done 100%. Anybody here can help me ?
