HELP! Duet 2 WiFi Configuration and DWC Upload???

PCNoobNeedsMajorHelp

So after changing M92 in the config file, and commanding G1 E10 F60, it is now extruding at a slow speed but I think it's still extruding too much. If I'm understanding the command correctly E=Speed and F= mm of filament to be extruded, correct?

-I ran the command 3 times and got a length of 100mm each time.

-Am I missing something, or is that what was supposed to happen?

Thanks,

@pcnoobneedsmajorhelp in a G1 command, E is the amount of movement command from the Extruder in mm. F is the feedrate (speed) in mm/min.

Did you reboot after changing the M92 in config.g?

Also, you can just send the M92 command in the console in the web control (e.g. while you're setting it up to find the right value), then update the config when you've found the right value to use.

Edit: the amount of extruder movement is measured in mm of raw filament being fed into the hotend. Of you're commanding 10.. and it's pushing through 100mm, then your M92 value must be 10x too high

Well that didn't work. I tried it all the way down to 4 and it just keeps going forever. Or not going enough. every time i try it i get a different result. Plus when have you ever hear of a stock ender stepper motor doing lower than 93. Also i noticed that my PanelDue is not in sync with the DWC and it also wont send commands from the PanelDue (unresponsive).

@engikeneer

Now the DWC is not responding. And yes I'm connected to WiFi

Is it possible you've sent a very long running command causing things to appear unresponsive?

Do things return to normal after a power cycle?

How have you set the steps per mm and what command are you sending for the extruder test?

@phaedrux

I've cycled the power several times and it still either isn't responsive or is a never ending extrusion. I first had it at 100, then I tried 10, then 4, 14, 15, 8, and lastly 16 and out of all those 8 was the closest at 25mm so I tried 16 to see if I could get close when I set it at 50mm. All the other ones either ran forever or were just way too long. There doesn't seem to be any rhyme or reason to it either. So I have 2 theories. 1: (there are relatives in town using up more bandwidth than usual so..) slow internet connection=lag in responsiveness. Or 2: the motor is broken.

-On the DWC I've commanded E10 F100, E10 F60. After than I manually clicked it to feed 10mm, at a speed of 1, then 5, then 30(which was wayyyy too fast). Then I tried 100mm at 1 and 5. And they don't reflect at all on my PanelDue.

Phaedrux

Can you post your current config as it is now so we can see what it's setup like?

It's an ungeared extruder, so the steps per mm will be pretty low regardless of the motor.

Have you tried following along with this? https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+4:+Calibration/40#s165

Yes, I'm using the guide.

You can add T0 to the end of your config.g so that the first tool is selected at startup.

I would suspect that the M92 E steps per mm is in the range of 90 - 120.

Extruding 100mm at 1mm/s will take... 100 seconds if the steps per mm are accurate, so you will need to be patient.

@phaedrux

Yes, I know this lol, that's why this is so frustrating and infuriating, because it's not even close. That's why I had my E steps set at 9, because nothing else is working and I'm ready to throw this thing out of the window.

-For example...Here is a picture of my screen, this is what I'm running... and then these are the results of the execution of that specific setting on the screen.

For reference I put this 45mm(long end) Allen Key compared to the filament that came out. In maybe 30sec

I really hope it's something stupid and obvious that I'm doing wrong or just not doing altogether, because I'm starting to worry. And, I mean.... I've just put so many hours into this build, ya know, and to have it be obliterated because of an e-step issue would be enough for me to just go back to my old board out of frustration. I just want to PRINT. Rant over. Sorry bout that, just had to get that out of my system.

Thanks,

@pcnoobneedsmajorhelp

If I need to send a video file of what's happening, I will.

Oh, and here's what the screen of my PanelDue looks like during all this. It's like its not in sync with the DWC

Phaedrux

You measure the filament going INTO the extruder, not out of it. You really need to look at that guide.

PCNoobNeedsMajorHelp

@phaedrux

I did that first, initially. And at 93steps it went way past my line. I've calibrated printers before. My concern is when I run the same program 3 times and I get different results. I assume that when my black line disappears at a high speed at 93 steps and then keeps going, and going when I set it at a low speed, and the next time I run the same program it spits out nothing....that it's not extruding correctly. That coupled with the fact that my PanelDue says its extruding different values that my DWC is.

@phaedrux

After the 8th time measuring out my black line, I stopped because there's no point to try and awkwardly get in there to measure it if I know its going to be wrong. That's when I started to look at how much was extruding out of the nozzle.

What do you mean by that?

Mark the line farther up so that it doesn't get sucked down past where you can measure.

@phaedrux

So if you look at the two pictures above, one is of my computer screen showing my extrusion setting on the DWC and the other is a picture of my PanelDue with the extrusion settings pulled up, and they don't match.

Just realizing that I never sent the picture, my bad.
