Skirt Always On

Using PrusaSlicer 2.3 for an Eryone ER-20.  It always prints a brim of about 6 lines 1 layer high.  I have shut off skirt, brim and supports and yet it still appears.  The bed has significant holding power so I do not want this.  The glass textured bed makes this awful looking and nearly impossible to get rid of.  PrusaSlicer is great, love all the amazing features, but this is a deal killer at the moment.  I also do not want to lay down a raft.

RE: Skirt Always On

Without seeing your settings, it's tough to give any specific advice. It sounds like your settings should have turned the brim off. Save your current 3MF project file, zip it up, and attach it to a reply here so we can see your part & settings and give better recommendations.

@bobstro---thanks.  Below is the file.  All parts I slice turn out the same.  Very frustrating.  PrusaSlicer is WAY more advanced than FlashForge Print, and it is the recommended slicer for my Eryone ER-20.  I want this to work as the printer is affordable as a small print farm for my business.  I am not blaming the software, just my inability to turn the skirt off.  The color of material shows it is a skirt.

I loaded your project into PS 2.3.0 on windows 10.  Your settings have a brim of 5mm defined.  So its no wonder its slicing with one.  In fact you have a loop set 4mm out from the part which is intersecting the last 1mm of the 5mm brim. 

 

When I configure to 0mm the brim goes away.

On my prusaslicer console it shows zeros on all the skirt and brim entry's.

Hence the reason I am reaching out to this forum.

When I configure to zero it still happens.

I reloaded the file I exported and sure enough it has a brim.  I remove it by zeroing out like you said Neophl and it still shows up.  There is a glitch in this somewhere...

RE: Skirt Always On

Well I can say that your saved project is not setting those values to zero.  

I have seen this before with a user who imported a profile from somewhere online and then they had trouble setting values as they werent actually being changed no matter what they set them with.  IIRC they uninstalled everything, wiped they profiles directory (which is not removed on uninstallation) and started from scratch again.  After that they didnt have any troubles.

You didn't import your profile from somewhere did you ?

As an experiment, use the wizard to install a basic prusa mk3s printer, select it and then try slicing with the brim on zero to see if it produces one.  If it doesnt then that would lend credence to a profile issue.  
The next step I would try is setting the brim to zero and saving the profile as a new one.  Then select the newly saved profile and slice and see if the saved version actually saved with brim=0mm.

The other thing you could do is to save a config bundle from your installation and zip it and post that here.  The config bundle will have the saved settings from any custom profiles and we could take a look through and see if anything jumps out as odd.

I loaded the prusa mk3s printer as you suggested.  No brim unless I enabled it.  Posted is the config as sent by my printer's manufacturer.

Thanks

YOU DA MAN!  Uninstalled and reinstalled, then did a direct download of the config file from eryone website; not off their included micro SD card.  NO BRIM!

 

Alas, all for naught as it won't even print anything now.  Eryone ER20, quietest, smoothest, fastest auto-levelling 3D printer I've ever had when printing the TEST FILES, and utterly worthless on ahything you want to rpint.

RE: Skirt Always On

Sounds like you need to work out a proper set of profiles for the Er20.  
You might want to check out Bob's website here https://projects.ttlexceeded.com/3dprinting_prusaslicer_profiles.html which has lots of useful info for profiles.

If you have working gcode then that should allow you to figure out suitable start/end gcode to add.   Then setting the rest of the physical parameters for your printer shouldnt be too hard, you can read back the eeprom settings from your printer using M500 and plug those into the prusa slicer profile etc.

I did download that ER20 config you linked and it looks like it was modified from a prusa printer back in version 2.2.0.  I also know why its having problems and it is the same reason as the other user I remember.

When you look at one of the proper profiles they are split into sections, so a printer profile will have settings for the printer, theres a filament profile section and a print settings section.  These all correspond to the 3 drop downs that let you choose your print, filament and printer profiles.  That Er20 profile contains settings for all 3 sections but all under the Printer.  So when you change your brim using the Print settings area the PRINTER section also has a brim setting (of 5mm) which is over writing it.  And as the settings for the PRINTER section will only edit those that belong in that area you will NEVER be able to change any setting that is in there. 
Basically those supplied profiles are utterly screwed up as all 3 profiles settings are bundled into one.  Looks like they copied the settings list from some generated gcode and edited it into a ini file without understanding what they were doing.  There will be many other settings that you can never actually change in practice due to that profile.

Personally I would start with  taking screen shots of all the printer settings pages (extruder, bed size, all the custom gcode sections etc) so I had a record of what was in there.  Then I would run the wizard and setup my own custom printer to get a clean template.  After that using the screen caps I would then manually enter the required details into the Printer settings pages.   Then save the new edited profile.  That way you will have a clean printer profile with only Printer settings in it.

All you really need is the Printer profile.  The filament and print settings ones can then be copied from one of the Prusa system ones.
