Printer setup, failed prints, calibration, materials and projects that turn settings into visible results.
Troubleshoot from symptoms to settings. Printer model, material, temperatures and a photo of the failure usually matter more than a guess at the cause.
Two parts that fitted beautifully with one PLA brand are now frustratingly tight using another. Same CAD dimensions and printer, but the new filament produces slightly different wall measurements. I can force the joint t...
A spool of PETG that used to print cleanly has started stringing more. It has been sitting on the printer for a while and I can hear the occasional tiny pop during extrusion. My first instinct is to dry the spool before...
I'm printing an L-shaped bracket that will hold a light shelf, not a decorative model. The first version looks lovely but cracked along a layer line when I tested it by hand. I'm using PETG with four perimeters and moder...
My PLA first layer looks fine on the left side of the plate but barely sticks on the right. Same model, same 0.2 mm first-layer height, same bed temperature. I cleaned the build surface and tried a small Z-offset adjustm...
I have a 220 mm tall, fairly narrow part that looks clean for the first two thirds, then the walls start showing obvious ringing/ghosting near the top. The same printer/settings produce clean shorter parts. Belts feel pr...
On my printer, circular holes are consistently undersized even when the outside dimensions of the part are close. For example, a 6 mm modeled hole ends up around 5.6–5.7 mm depending on orientation. I can compensate in C...
