Topic: new solidoodle .3 slicr profile DISASTER

i really wish i could turn the clock back and just get rid of these slic3r profiles.

every single run is failing due to this new feature that as soon as print starts it goes to the print bed and extruded a big blob of plastic which it then drags along the bed and stopes the first layer from setting down.

i would just fall back to skeinforge put that itself has issues that it decides to retract the whole filament out of the extruder and then dry runs without even turning the extruder.

its getting very depressing

You can easily disable the anchor that the slic3r tells the printer to extrude. 

Open up the slic3r settings and go to the 'Printer Settings' tab and choose 'Custom G-Code'

Find the line in the 'Start G-Code' section that mentions anchor and delete it.

It is most likely dragging the plastic back because the back right corner of your bed isn't level with the rest of the platform.  I had the same issue and removed the anchor line from the start g-code and added a 2mm brim under the 'Skirt and Brim' slic3r 'Print Settings'.  This has worked very well for me.

If it isn't sticking then id assume a few things are happening.

1. Your bed isn't level or even somewhat close

2. Your first layer height isn't set right using the z limit screw

I had the same issue when first switching to repetier/slicer and to be honest sometimes it will pull it and drag it but I also use a skirt which will usually catch it by then

I always had that issue with PLA. I inserted some g-code to make the extruder lift away from the anchor before moving to print. The worst I get now is a single string in the middle of the print.

G1 E25                           ; extrude anchor
G92 E0                           ; reset extrusion distance
G1 Z5 F300                       ; move platform down 5mm
G1 Y20 F3000                     ; move away from the anchor
G1 Z[first_layer_height] F200    ; move platform to the first layer again

I would be inclined to say the only reason you've had that issue is your extruding a good bit of filament there creating a pretty big Blob that's sticking to your hot end.  I think lawsys is set to 7mm extrude and yours is 25mm.

Yes. I increased it because PLA tends to degrade when it's heated for a long time. But the same problem persisted with a smaller anchor.

Re: new solidoodle .3 slicr profile DISASTER

What about KISSlicer? Is that any better or pretty much the same thing? I had issues with the Slic3r on one piece I have printed using Skienforge with no issues. The part was two walls at right angles with some large 3D letters on the opposing Faces. Slic3r added threads at a 45 degree angle between those faces. Real strange.

I switched to PLA and I'm having issues with the first layer. Otherwise I've had some so so results. Considering they were the first with this material I'm not upset. But I do need to solve the first layer issue. I was heating the bed and if I printed a raft it all worked pretty much. But no raft no stick. I'd like to add a brim but haven't figured out how to do that yet.
