Duet Wifi config on a Flashforge Creator Pro
-
If you connect the fans on the extruder heatsink to fan1 in thermostatic mode, the printer will be quieter when the hotend isn't hot.
I have those fan connected on fan 0 and fan 1 set to start at 45degrees. The part cooling fan is set to start at third level but that one isn't working automatically since I can't tell slic3r that P2 is the part fan. Starting it manual with M106 P2 S200 works perfect tho.
I see three solutions, if I understand the setup correctly:
1. Connect both fans on the extruder heatsink in parallel to the Fan1 connector, then the Fan0 connector will be free for the part cooling fan.
2. Swap the Fan0 and Fan2 connections.
3. Use the fan mapping feature of the M563 command.

Thanks dc42
I haven't had time to check what command slic3r uses in the gcode yet to start the fan but my first thought was to do that and then remap the extruder fans so it works through slic3r. Will have a look at your methods to but first it's Christmas time so will be a few days -
Sli3r sends M106 commands with no P parameter to control the print cooling fan. So it needs to be connected to Fan 0 unless you use fan mapping in the tool definition.

Then I've fitted the IR probe to my flashforge. Just test mounted it for now since I have a E3DV6 in the mail. I have set it up with G29 mesh probing and got a good result when I did the first run. -0.078/0.037 was the first test. When I did one after I put glue stick on I had offsets from -0.230/-0.030. Isn't that much deviation? I do a G30 when the prints starts (in my G28 routine) can that disturb anything?
And I couldn't figure this out but do I need to do something for the printer to remember my G29 height map or is that done automatically until I do a new G29 S0. Even after power cycling the printer?

I had the same exact noise issues with my Creator Pro , I dumped the thermocouples, the hot ends, the fans, the carriage, the stepper motors etc. I had good luck with a normal thermistor and now I'm running PT100's with an E3D Cyclips / Chimera and external Bowden extruders.
In any event the only thing I found that helps with the thermocouple issue is to get the wires far far away from the stepper motor wires. They induce current into the thermocouple wires and you get all that noise.

The thermocouple problem is solved with routing the wires away from the stepper wires. Haven't had a problem since that. I will change them as soon as my E3DV6 extruder comes with a normal thermistor.
Got any pictures of your setup? The carriage with those springs that wobble all around is a nightmare..

I'll get some pics of my setup. My goal was to reduce weight as much as possible to achieve better accuracy and/or far more speed. I replaced the stepper motors a few times tying out some combinations. I'm currently running a short pancake motor on the x-axis to cut down even more on the weight the Y axis motor has to move around with great success.
The stock Z motor on my FFCP is only rated for 400 ma max and the X and Y at 850ma. They are high inductance motors and really are kind of designed for higher torque and not so much speed. I switched to 1.2 A on the Y side with a different stepper and 1 A with that pancake stepper on the X side. I can do 150mm/s prints without issue and normally print at 90mm/s. I also went with 0.9 deg large steppers for the bowden extruders on the back with mk7 drive gears. Don't fear the bowden, my prints are of far better quality then I ever got with the MK10 setup.
I've got a custom E3D V6 carriage that I snagged off TV and then modded to work a bit better including mounting the stock active cooling fan, inductive sensor or BLTouch. I also of course have a custom carriage I designed for the E3D legends pack. Spring loaded bed clips for holding glass that I printed in Polycarbonate that make switching out glass a 1 second job. Also my own (mostly) design.

Just picked up a DuetWIFI for my FFCP. Would you guys mind sharing your config so I don't have to guess at most of these parameters?
Thanks!

I would really like to see the config file also.
I just got done wiring up my Dreamer and have no clue what to set most of the parameters too.
I know the Creator Pro is similar and it would really help me out.
