I will, I will check it in like 4 hours since it’s an 8 hour print.Just let us know
If the bed is too high, and the nozzle is dragging the bed, you extruder can't push the proper amount of filament out - it will slip/grind. The fix is to lower/level the bed, so you filament can escape the nozzle.I think I fixed it, the extruder gear was too tight and was grinding the filament, I loosened it, and it seems good so far.
I leveled it, the issue was that the extruder gear was grinding down the filament and made it too thin by the time it got to the extruder. I loosened it up and it’s printing pretty well so far.Bed not level for sure. Top parts the brim is thick (bed too low) bottom parts brim is too thin (bed too high).
Do a "paper level", then download and print a level test. Adjust the level as the printer is printing each corner, so you get proper squish and not too thin. Then you should be good.
Bed level test, you may need to scale XY in Cura to fit your print bed -

The extruder should never change the size of your filament. That would take an extreme amount of spring pressure to do so. Not only that, but I’m pretty sure your extruder gear is beveled and can’t really deform the material it’s feeding to a great extent. Is your spool free spinning? Maybe the roll was bound?I leveled it, the issue was that the extruder gear was grinding down the filament and made it too thin by the time it got to the extruder.

It isn’t beveled, it’s sorta like a pinion gear. I loosened the spring pressure and it isn’t grinding as much. The spool is inside of a heating box that lets it roll.The extruder should never change the size of your filament. That would take an extreme amount of spring pressure to do so.

I don’t have one like that.
Sure you do…I don’t have one like that.View attachment 185801
I think it’s the filament, this spool has always been a bit finicky. It’s cheap filament, my Hatchbox prints much better than this Overture.Sure you do…

Also, I believe you are over extruding your filament, which is why it’s shredding / slipping on the filament, not due to roller tension, if anything the lack of tension.
What your issue truly is is bed level and z offset IMO. This leads to the nozzle being blocked/clogged by the bed being too close, leading to the extruder gear slipping and chewing up the filament.
Yes, this. but, if the printer is now printing good, then good.What your issue truly is is bed level and z offset IMO. This leads to the nozzle being blocked/clogged by the bed being too close, leading to the extruder gear slipping and chewing up the filament.
I lowered the speed, it was previously at 215c, I bumped it up to 220c. The print speed is 50mm/s I believe. It was at 60mm/s before! Thanks!From the looks of it.. you're having your printer print a bit too fast..
Your hotend is not melting that filament quick enough to keep up with the speed you've set.
Try upping your temperature a bit (~215°C).. and slow down your print speed.
I've crank down my initial speed (1st layer) at 15mm/s then after that it's ramps up to 35mm/s as your nominal print speed to have better consistency.
You're be surprised how even "bad filament" will be better handled when you do.
Give it a shot and see.
If the tension was too high, it wouldn’t slip. Reducing the tension is just letting it slip with less damage. Your e steps need checked or calibratedOk, so the print turned out perfect with no layer lines! I think the tension was the issue, the gear was destroying the filament.
I checked my esteps and they are way too high… I need to recalibrate it, I will do it tomorrow as something is printing right now.If the tension was too high, it wouldn’t slip. Reducing the tension is just letting it slip with less damage. Your e steps need checked or calibrated
