I didn’t think so. But when I measure extrusion I get 0.56mm
Try a test print, re-sliced with .5, you can’t really measure the extrusion it will vary wildly due to many factors.
Do you have extruders with .5 nozzles?
Is your bed level? The priming ring around your print looks way too thin on one side, and almost looks like it was airstruded on the other.
There are a lot of things wrong with that print, I wouldn’t jump to hardware issues yet.
Are you using the mp3dp firmware or the mpcnc?
That first layer is way way too close, and all that stringing means too hot usually (with PLA).
Here are two files I actually use on my mp3dp.
The 5 indicates the .5mm nozzle, I rebuild all extruders before I ship them I could have put the wrong nozzle on.
J5-XY.zip (1.6 MB)
J-XY.zip (2.3 MB)
Checked it. It’s really close.
The 0.5mm nozzle wouldn’t explain the 79mm extruded.
There are too many things not adding up. 79 extruded doesn’t explain the .56 extrusion width either.
I am kinda lost that’s why I put up the files I know should work then we can see what happens. With my hardware, my firmware, and my sliced files we are down too only a few things once we see some print pics.
Yeah, but you don’t need any gcode to know that 79mm isn’t going to work. I would guess that 0.56mm is also far enough off to be a problem, but I’ve never measured it. What am I thinking? I’ll go measure that now.
I’m thinking there has to be a problem with a) temp control, b) extruder gears/idler, or c) stepper motor driver adjustment, if it was underpowered it could cause the 79mm too.
Mine is also about 0.56mm-0.58mm. I heated the nozzle to 195, and extruded about 15mm of filament, let it cool down, and measured with my micrometers.
The 79 could be from just about anything, way to many variables. lcd error, tension, clog, driver over/under power, wrong steps, drive gear, clogged drive gear, bad filament, wrong sized filament, loose gear, ect.
Best to leave that and check other things that are easier to narrow down. one step at a time.

From my best guess with the calipers, the nozzle I have it 0.4mm, and I’ve been getting good prints with my slicer set to 0.4, so I think the 0.56mm air extrusion is a red herring.
That is what I meant, .56 is is about right, the 79 is not. If it was under extruding the .56 would be less. I feel it is something else.
Would the 0.56 be less if it was having trouble extruding? I guess maybe depending on the problem. If it only pushed through 79mm instead of 100, then it would still be 56, I would think.
Here’s a silly question, can you confirm that you have the esteps set to 200? In the LCD you can check by Control->Motion->Esteps/mm. The default in Ryan’s firmware is 200. If this is set to 160, then it would cause the 79mm.
I was never able to get the LCD to work.
You could have uploaded something smaller to print;o)
Starting to print now using Repetier.
Just get a few layers down. it was the only parts I had matching and verified.
