Test 132

[guest-352]

Hi first

---

I have a problem with my 3D printer and I just do not get any further. Therefore I turn to the forum now. Maybe one of you has a solution.

#DETAILS#

• I am using a Creality Ender 3
• I replaced the original mainboard (v1.3 I think) with a new version (v4.2.7, my goodness is that suddenly quiet xD)
• I use Marlin firmware v0.0.6
• I also bought extra belt tensioners with adjusting screws in order to be able to adjust the tension on the x-y axes more easily and more reliably
• I had to replace the hotend because it broke apart while cleaning it xD
• I use an analog caliper to measure print results
• I still work with PLA (1.75 mm from Sainsmart)
• I use Ultimaker Cura as a slicer, now version 4.10

#ACTUAL ISSUE#When I try to print an M6 washer as a test object, I notice that there are unsightly deviations in shape. I noticed the following:

1. The bottom layer is always approx. 0.2 - 0.5 mm too wide in diameter.
2. After the bottom layer, the diameter suddenly decreases at first and gradually increases up to the target value.

Also there are a few pictures of the matter attached. The washers should each have a bevel on the top, which also points upwards in the pictures.I've tried a lot: on the one hand to change the settings in Cura, on the other hand to readjust a few points on the printer. So far I have been unsuccessful.

I would be happy to receive suggestions for solutions!
