When you call something "Material" i am logically assume parameters such as:
Weight, price, diameter, maybe temperature too, yet "Material" reflects slicer settings that have no business being in the "Material"

Essentially what Matter Control has is "Slicer Settings", not "Material"

Same thing with "Printer"
Selecting another printer brings up its own set of materials that are not shared.
I have to duplicate materials in order to print with same "not materials but slicer settings" on another printer. And if i happen to need a small change, i have to make that change on both materials now instead of one.

It would make sense to be able to just pick the printer on which model will be printed on without the need to re-import the model specifically for opened printer in a new workspace.
Just print printer from drop down menu and re-slice. BAM !

I know understand Coast does and why. What i dont understand is why it has to coast in opposite direction at the travel speed. At the very least it could coast toward same direction.
Print speed: More settings ? There is too many already. The very basic one "Print Speed" is missing.

Do you have a link to that file ?
I'd like to look at its topology.

@grc said in Retraction issue:

and

Look into minimum extrusion required for retraction.
I set mine to 0 so it will retract strictly based on distance traveled.

If i set it to 10mm of extrusion, even if travel is far enough, it will not retract because it has not extruded 10mm PRIOR to that move.
See ?
I hope that helps.

Please forgive me for my none constructive criticism. I tried my best so here i go.

Coast at the end:
Is there a reason for [Coast at the end] to go in reverse direction ?
Sudden direction change is not only bad for the print, its also bad for the printer.
Imagine going one direction and then suddenly go back at 150mm/s travel speed ? Thats nonsense.
Coast should be at either print speed or at travel speed (optional) toward same direction. (This feature is known as combing in Cura)

Perimeters:
Inner/Outer perimeters change print direction. Why ?

Print speed:
Where is fundamental setting for [Print Speed] ?
I see allot of other parameters. I dont want to change 9 parameters to change entire print speed (except for travel)

Material selector:
Does it work at all ?
When i select different material, the only thing that i notice change is Outside Perimeter. Everything else including temperature stays the same.

Where is the "Save" button when i edit material properties ?

Are Material presets act (in theory) like printing parameters presets ?
So why not just name it "Presets" instead of materials if they effect (not at this point they dont) printing parameters such as speed etc ?

Export printer:
Exports .printer file containing excessive data, data that has nothing to do with the printer but rather print settings such as layer height, skirt distance, retraction settings etc, even materials.
So its not printer information, its printing information or what ?
Can this be imported ?
Does it import print settings with it ?
I am very confused here.

Any feedback on that ? Thanks guys.
I have allot more but i will keep them to my self for now.
