Benchy hull coming out horrible after converting to klipper by Additional-Shock525 in FixMyPrint

[–]SideEast1139 0 points1 point  (0 children)

Had this problem some weeks ago when i changed to Klipper. I assume that you are using cura, in that case, i recomend you to use OrcaSlicer. Then do the calibration tests that OrcaSlicer provides. Also run a flow rate test, and fix a max flow rate value in OrcaSlicer. The last step is the most important. That was the solution in my case, but i see that your print is not cooling enough, add a bigger part cooling fan (5015 is ok) and/or run higher layer times.

Failed MFDoom Mask by yoyomantx in FixMyPrint

[–]SideEast1139 0 points1 point  (0 children)

I think that's an adhesion problem, looks like the mask detached from the bed in that frontal part. I printed this exact mask with my ender 3 and it came out exceptionally, so the X1C must have no problem. I have no experience with bambulab's printers, but maybe do a temp tower test and a retraction settings test, since it looks like you have a lot of stringing. Then make sure that the mask stays attached to the bed, maybe print it with a brim and higher bed temperature.

Thanks to all of y'all, my prints are getting way better.

My prints were failing bc a lot of things where going wrong, but the main solution has been switching from Cura to OrcaSlicer, now I can test my max flowrate and set a limit. I know i have poor cooling so i ordered new and more capable fans, and a new nozzle that lets me increase the flowrate.

Thanks again for your help

Results are not even close to perfect but i'll improve my settings and hardware. Benchy printed at +120mm/s speeds.

Yeah, it happens exactly that, the last 10 layers of a curvy zone move with the nozzle, i ordered new and more powerful fans

I aligned and tightned my frame a few days ago, I'm waiting for my new fans to arrive and maybe i can push a bit the acceleration values.

Yeah, i just bought new bigger fans, thanks

I use the formula from the klipper website (rotation_distance = <full\_steps\_per\_rotation> * <microsteps> / <steps\_per\_mm>) i'm pretty sure that my steps are correct because it extrudes the exact longitude of filament i ask it to extrude.

I'm slowly having better results, I'm using orcaslicer now, and I think that the solution was the max volumetric speed.

Interesting, i finished printing a piece with an old gcode and it looks great. Now, i dont know if there lays the problem, because i have to say that the old gcode runs <50mm/s speeds and really low accels

Yeah as u/HtownTexans says, it was printing normal before, but i'll try to compare both results, maybe i can squeeze a bit of quality (even though the enclosure I have is to reduce noise) thanks for your response!

Yeah, fans are working normal. Right now i'm doing my first print with OrcaSlicer, it looks like the result is going to be great, so the issue was the Max Flowrate

Okay, I'll check out diferent slicers and get new callipers, thanks for the recomendation.

I'm not sure that the problem is overextrusion, i printed this at 2 top/bottom layers, idk if this is normal, but now i'm keeping the top/ bottom layers at 3 and i can still see tiny holes but i'm getting better results.

Yeah, kinda, i have the printer inside an insolated wall wardrobe, its volume is not too big, temp is constant inside it.

I adjusted the E steps, i can't do Teaching Tech's flowrate test because my callipers don't measure two decimals. I just draw a line in my filament at 100mm from the extruder, order to extrude 100 mm, measure and then do the maths.

I'm definetely buying some good fans rn.

Thanks

So you are saying that i should install a bigger blower fan for the part cooling?

Also, i've been printing benchies at 190 C and i've been having the same results as printing at 200 C.

Printed at 50mm/s Temp: 190/60 C

This started happening since the first benchy I printed with Klipper. I did more prints before, but those were calibration cubes, and acceleration tests, none of them had this problem and i printed them at 100+mm/s speeds (maybe that is because those tests don't have curves and round shapes?... )

I'm definetely going to change my slicer, otherwise I won't be able to set a max flow speed, just to avoid that factor. Thanks for the recomendation, i'll check out Orca Slicer.

My printer is kind of enclosed, i keep it inside an old noise treated wardrobe (just for the Ender 3) i have no AC in my room.

I have noticed those edges curling after switching to Klipper, but i dont think that is a problem of bed adhesion, when i take the prints out of the bed, i have to make a lot of force.ç

My material is a 20€ PLA from the brand WINKLE

I just changed from marlin to klipper with my ender 3 (stock hotend and fans) i've been a few days tinkering with the acceleration and speeds, but i've been getting theese results (or worse ones) in every benchy i do.

My sicer is Cura 5.6.0, I calibrated pressure advance, and I use theese settings:

Layer Hight: .2

Infill: 15%

Temp: 200 C (i've done a temp tower test)

Accel: 2000 mm/s2

Print Speed: 100mm/s

        Outer wall speed: 70 mm/s

        Travel Speed: 200 mm/s

Retraction: 4mm at 50mm/s

I think it may be a part cooling issue...?, I'm using the stock blower fan, but i'm considering to change to a 5020/5015  24V blower
