Adhesion field is not working #159

Open PeggyFree opened 6 years ago

PeggyFree commented 6 years ago

Hello, even if I chose "None", a brim is created. I installed latest Octoprint three days ago and installed this plugin via Plugin Manager. When I chose "Advanced" -> "Adhesion" -> "None", then slice + start printing, a brim is printed. The original STL have no brim, I printed it yesterday using a Cura 3.4 STL file.

This slicer is linked to Cura 15.04 engine. I didn't launch Cura 15.04, just let it in a folder for this Slicer. What's wrong?

Please post the gcode here and I'll take a look @PeggyFree

Just in case you didn't know - there will always be a couple passes of plastic around the 1st layer. It's called "skirt". https://rigid.ink/blogs/news/3d-printed-raft-brim-skirt

PeggyFree commented 6 years ago

I'll post the gcode asap.

I don't see any gcode. don't think they were uploaded successfully to github. You may want to zip them before uploading.

gcode.zip Here is the gcode atrached

PeggyFree commented 6 years ago

@kennethjiang It's a brim, isn't it? (sorry for the bad quality)

Sorry for the delay!

Yes it was brim, not just skirt. A bit strange. Does it happen to other STLs you have?

Can you also attach the STL file, as well as the slicing profile you used?

PeggyFree commented 6 years ago

Thank you for your answer. I'll be back with another example + STL file.

PeggyFree commented 6 years ago

Here I am with new files. I get a brim again, while it is selected "Adhesion = None" in slicer. And the overall print speed is more than 10x lower than expected. 4h print time instead of 24mn.

About the print speed, maybe you'll see what's wrong in the gcode, I'm not familiar with this. I changed the slicer print speed x8 (for instance 150mm/s for outer shell etc.), it didn't change anything. Then I changed the printer settings : maximum feedrate of the individual axes x10 : 90000 instead of 9000. With these settings and 50mm/s outer shell speed in slicer, I get a 2h print time instead of 20mn (see attached in case it helps).

@PeggyFree You are right that even if when "adhesion" is "none", it will still generate brim in gcode.

The Slicer Plugin correctly passed the parameter adhesion=none to OctoPrint, which somehow passed the wrong parameter to Cura. So my best guess is that some bug in OctoPrint gets triggered by a specific setting in your Cura profile that results in the extra brim.

You can log a bug for OctoPrint at https://github.com/foosel/OctoPrint/issues/new .

A work around is to use a different ini file. I attached my ini file which doesn't suffer this problem. May you can tweak my ini file to fit your need?

Thank you for your analysis and help. Before testing your PLA settings i have to solve another problem. The motors are whistling loud during print, only when slicing with octoprint. I have to find why before anything else.
