Ender 3 Pro configuration

@baesjerker said in Ender 3 Pro configuration:
I will look into how to use relative extrusion in Cura.
It's an option under the Special Modes menu heading. It might be hidden by default.

@phaedrux Awesome. Found it.

Now everything seems to be working like it was when using my stock Ender 3 Pro board.
Print quality is more or less the same, maybe a bit worse than before, but I need to experiment a little more with the duet config and in Cura.
But the stepper motor noise is almost gone they are so much quieter now!
I also had to lower the current for the stepper motors. They where running really hot using stock (x, y, z, e) (725, 725, 725, 900). Trying to find the magic numbers here.
I see everything from 400 to 900 on this forum.

The Ender 3 uses low current motors and 24V power, so I am not surprised that you need to reduce motor current. Stepper motor current is adjustable in steps of 100mA on the Duet WiFi/Ethernet, and 50mA on the Duet Maestro. So 600mA may be a good value to try, perhaps a little more on the extruder motor if necessary.

I've been using the following currents on my Ender 3 since I put the Duet wifi in it without issue.
M906 X950.00 Y950.00 Z850.00 E900.00 I30I think the motors at their hottest hit mid 40C range so not hot for stepper motors.
-
the ender 3 motors are
x,y,z 0.84A
e 1A
https://gist.github.com/knoopx/e6c40a009e796203b93a75a3ed6a5ab8950 might be a little bit hight for x and y.
-
I guess I can try lowering the current. At some point I'm going to replace the X and Y stepper motors with 0.9 degree ones with more torque now that I'm using a direct drive extruder as well as glass with PEI on the bed.
-
@dc42 thanks. I will try that.
-
@veti you are right. I missed the 90% -_- thanks. My motors run extremely hot with what I already have so I will try with 600(x, y, z) and see.
-
Haha so the 1000 mA I had set in my config mayyyyyy be toooo much is what you're trying to say
hmmmmm hahaha

hmmm, I wonder why yours are fine...800 it is for now
-
The Y and Z motors do not get that hot using 700-800, but the X motor gets extremely hot. I can hold my hand on the back of the X motor for 2 seconds or so and then I have to let go. I have checked belts and everything else. 600 Seems to work great. It still gets hot, but not 800 HOT!
-
thats strange as the x and y should be the same motors.
have you measured the resistance of the phase for both x and y motors? could be a production issue. -
@veti I will check on it later today.
Do anyone know if I can use the Ender 3 Pro display with the duet?Edit. Nevermind. Found out by searching 12864.

with the duet maestro yes. you need another cable for the second exp and swap the plastic housing of exp1 and exp2 around. and connect those to the maestro

When I was looking to do this, there was very little, if any, documentation on how to do this. It was exceedingly frustrating as I was probably doing it quite early on. I would have like to do this because I gave my maestro away because I just said "f*** this!" and bought a wifi.
I have an issue with my printer now, since the SD card got wiped, that is making the nozzle crash into the bed and it is exceedingly frustrating.

first check that your probe/endstop triggers using

https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probeI suspect it has to do with the calibration of the z probe because it homes perfectly, the z end stop is at the top for this reason and I use the BLTouch strictly just to mesh the bed.
It is when I try to mesh the bed with the DWC that it just drives right into the bed, it did the first time, now I know it will happen as I tell it to stop 50 or 25 mm away from the bed, wait there for a couple moments, then go to the bed mesh. I am going to recalibrate the z probe after I watch this OpenAI live symposium:)

Hi guys. Back again with some more issues.
On the stock Ender 3 Pro board I never encountered stringing. Not once.
Now I have extreme stringing issues and blobs all over the place.
What I have done so far:
- Calibrated extrusion.
- Tried different extrusion distances.
- Tried different print speeds.
- Motor mA from 500- 900.
- Changed nozzle. (Not clogged)
- Changed tubing. No difference capricorn/stock.
- Changed couplings.
- Tried temps from 190-220.
- Used 4 different PLA filaments from 3 different makers. Green, red, black and white.
- More/less tension on x and y belt.
Edit: My wild guess is that this is something slicer related.
Edit 2: Cura = Extreme blobs and medium stringing. Slic3er = No blobs, but extreme stringing. -
We'd need to see your config.g and your slicer profile to get an idea of what to change.
Try this cura profile. https://www.dropbox.com/s/2nk6szy3ag97lsj/Ender3Profile.curaprofile?dl=0

Hi. Thanks. My setup is based on the settings @PaulHew posted earlier. I have only changed motor mA, z height and the heaters resistance.

I will post my Cura profile first thing in the morning.
I will try that profile.
