found it:
A factory reset marks the stored settings as invalid and loads the default values (at least that is how it is intended to work 🙂).
The runtime statistics are preserved.

The intention is to compare the pointer with zero, does it work, if you change it like this?
return (index < MAX_MACHINE_SETTINGS) ? settings[index]!=0 : false;
But i think, the whole function is not used at all - you can probably just delete it... 🙂

Fusion 360 only lets me directly send components to Cura one-at-a-time
I think, the "Merge Models" function in Cura is useful in this case:

it went over every line twice. Can I get it to draw the line only once?
I'm not sure, i think that's simply how the CuraEngine lays down the paths.
If it's possible at all, the "print thin walls" feature may influence this (dunno 🤷♂️). -

I have combing off, retraction enabled, z hop when retracted also enabled with a z hop height of 1 mm.
What's the value of "Retraction Minimum Travel"?

How do you send the request to the printer?
Does it work if you test the request on http://<ip address>/docs/api/ ?

Oder bin ich mit meiner Vermutung auf dem völlig falschen Dampfer und der Fehler steckt doch in einer tw. verdreckten Düse??
Wenn die Düse frei ist, hätte ich eher den PTFE-Coupler in Verdacht. Das ist ein Verschleißteil und muss regelmäßig erneuert werden. Wieviele Druckstunden hat der schon hinter sich?
Der Bowden-Schlauch kann natürlich auch verdrecken/verschleißen und dann wird die Reibung zu hoch. Aber der lässt sich ja relativ einfach abnehmen und säubern/testen/austauschen.
Hier sind ein paar Details dazu:

I changed it back to 1600 and went back to the original Extruder.
7 hours ago, dspy8083 said:Do you believe I ran into this problem because mine printer is an um3+ ?
No Ultimaker printer uses 1600 steps/mm for any "original" extruder - and what the heck is an UM3+ ???
Perhaps you should start over and explain at first what exact (type of) printer you're talking about...and where did you get it?
Do you have pictures? -

The project is just a simple 25mm square single wall calibration cube
Hopefully a closed (solid) cube and not with the thin walls actually modeled?
Cura will always generate two passes along the walls in case of the latter. This would not produce comparable results, you need extrusions with a single pass for this kind of calibration.

I have in Cura reduced the e step setting to 311 and I am getting very poor print quality.
I don't think that is possible at all. How have you done that?
The only relevant places are the JSON-files in /usr/share/griffin/griffin and the "override file" in /var/lib/griffin (if present).
9066.json belongs to the UM3 and 9511.json to the UM3 extended - both inherit the default steps from um3.json.
I don't know which file is changed by the Bondtech update tool.
5.2.11 is the current firmware for the UM3 (AFAIK), so that part should be fine.
If in doubt, make a copy of both folders (with WinSCP or a similar tool) and upload it here (as a compressed zip-file).

How do you change the flow rate in Cura?
I guess a few more explanations / screenshots or the saved project file would be of great help.
There are a dozen (or so) flow settings in Cura...

Vielleicht kann ein anderer versuchen die Datei zu öffnen und schauen ob Cura dies auch als Projektdatei erkennt, das wäre Net.
Das ist nur ein 3D-Modell, keine Projektdatei. Eindeutig ein hoffnungsloser Fall... 😃

My print head moves to the prescribed coords and then shortly after it resumes printing. Is it best to use the filament change script? What is the best way?
It highly depends on the (kind of) firmware the printer uses. "Pause at height" uses the command "M0" to do the actual pause and "Filament Change" inserts "M600".
If the printer does not support these commands it will ignore them (in the best case) or it will perform something completely different (in the worst case).
There's no standard for gcodes, but if the firmware type is known, one can at least make well-founded assumptions. Sometimes it even depends on the firmware version or how it is configured.
There are additional pause scripts for Repetier and RepRap firmware which are using different commands. There are printers with (in-build) menu-driven functions to assist filament change during pause, while others don't allow it, and so on.
Your chances of qualified answers are much higher, if you tell us the printer model and/or the installed firmware(-version).
If you use a printing host like Repetier or Octoprint another layer of complexity is added. So this would be interesting as well.
Good luck!

Am I missing something? It did not behave this way in the past, and I can't wrap my head around all the retractions and extrusions it adds.
The script has always behaved like this as far as i can see (at least since 2018).
As soon as there is a non-zero value for "retraction" it adds these back and forth things 🤷♂️

Hope that makes sense.
not quite, sorry... 🙂
There's no need to overwrite the operating system, rather it's essential for running an app... 😁
Here are some basics about AppImages:

What mods must I do to add the Tenlog printer profile to the selection?
There are at least the extruder definitions missing, take a look at the Cura wiki:
https://github.com/Ultimaker/Cura/wiki/Definition-Files-Explained
Most probably there are a few version numbers that have to be updated as well. The log file (cura.log) will list those errors that prevent the definition to show up.
The location of the log file is explained in the readme file.

The retraction is not -2mm but becomes -20mm why?
G1 F200 E20 G1 E-2because the e-axis moves (slowly) from E=20 to E=-2 (22mm backwards)
Those are absolute coordinates like set with M82 a few lines above.
Here is a quite comprehensive gcode overview: https://reprap.org/wiki/G-code

arrow places where should be retracted and machine does not do this
Looks like "combing" moves. Check the combing settings (section "Travel").
Set combing mode to "not in skin" or switch it off.
And check the travel moves in the Cura preview, moves with retraction are light blue. No need to waste material.
-
In addition I would place the tower closer to the printed object to avoid such long travel moves in between.

You probably use the printer definition "Creality Ender-3" - not the "....Pro"
The definition for the Ender 3 has "disallowed areas" - displayed in grey on the build platform:
https://github.com/Ultimaker/Cura/blob/master/resources/definitions/creality_ender3.def.json#L15
A definition for Ender-3 Pro was added just a few days ago, it may be officially provided with the next Cura version (dunno).

Yep - the file is damaged somehow. It contains non-ASCII characters - blame the SD card! 🧐

The UM2+ stepper has no more power than the UM2 stepper. They are the same torque. Same power. Same steps. Different shaft. The difference is that the "plus" feeder has 2X gearing to get twice the torque at half the speed. This has nothing to do with the stepper.
Ups - wait a minute...
The feeder motor for UM2+ and UM3 has 1.8° per step (200 steps/rev), and a gear reduction of 36:11 - while the UM2 feeder motor had 0.9° per step (400 steps/rev) and no gear reduction.

The PTFE coupler is a consumable and has a limited lifetime. This would be my first bet.
