I have been trying to print a larger model and keep having an issue with a wall defect that appears where the 3d print head approaches the wall from a different direction. Attached is the larger piece I am trying to print. Also attached is a test STL that replicates the issue with less filament and time.
I have calibrated extrusion and retraction repeatedly. At first I thought it might be horizontal hole expansion being negative…but that is set to 0. I am using Cura 5.0.
Do you have any play in the bed? It shouldn’t really deflect if you grab the edge and pull up and push down.
There’s also a long thread about a bump in the Y axis that might be relevant.
By hand, I cannot detect any play in the bed.
I will read through the Y axis thread and see if that applies. Thank you for the reply.
That looks an awful lot like mechanical backlash in the feedscrew. There’s a software compensation for it that’s been discussed on this forum. There’s no hardware solution for it unless you’re a machinist.
Unless it’s play in the head/x-rail bracket. Bed was mentioned checking but not head.
