The first layer is everything. Get it right, and the rest of the print takes care of itself. Get it wrong, and you’re coming back to a spaghetti monster or a print that popped off the bed three hours into a twelve-hour job. I’d estimate that 70% of all failed prints I’ve dealt with —…
You finally dialed in your retraction, leveled the bed perfectly, and calibrated your flow rate. The print looks great — at 60mm/s. Then you bump the speed to 150mm/s and suddenly every sharp corner has ghostly echoes rippling across the surface. Those ripples have a name: ringing. And the fix has a name too: input…
Photo by Jakub Zerdzicki on Unsplash PLA is the most popular 3D printing filament on the planet, and for good reason — it’s easy to print, doesn’t smell terrible, and produces parts that look great right off the build plate. But “easy to print” doesn’t mean all PLA is the same. I’ve gone through more…
If you’ve spent any time in 3D printing communities, you’ve seen the debate. Someone posts a gorgeous benchy printed at 200mm/s, and the comments immediately split into two camps: Klipper enthusiasts telling everyone to switch, and Marlin veterans saying it’s perfectly fine as-is. Both sides have valid points. But the right choice depends entirely on…
Photo by Jakub Żerdzicki on Unsplash Not all PETG is created equal. I learned this the hard way after burning through three spools of bargain-bin filament that strung like crazy, popped with moisture bubbles straight out of the vacuum bag, and produced parts that looked like they’d been printed underwater. Since then, I’ve tested over…
3D printer homing the wrong way? Learn how to fix reversed axis direction in Marlin, Klipper, and RepRapFirmware. Covers stepper wiring, firmware settings, and CoreXY troubleshooting.
3D printer skipping layers on one side? This troubleshooting guide covers every cause from loose belts and eccentric nuts to stepper driver issues, with step-by-step fixes.
Few things are more frustrating than watching your 3D printer’s nozzle drag across the surface of a print, gouging lines into what should be a smooth top layer. Nozzle dragging — sometimes called nozzle scratching or scarring — leaves ugly marks, can knock small parts off the bed, and in severe cases will ruin a…
Why Would a 3D Print Only Warp on One Side? Warping in 3D printing usually affects all corners equally. The bottom of the print shrinks as it cools, the edges pull up, and you get the classic curled-corner look on all sides. But what happens when only one side warps? The left side stays perfectly…
What Causes a Rough Bottom Surface on 3D Prints? You’ve dialed in your top layers, your walls look clean, and your overhangs are respectable. Then you pop the print off the bed and flip it over — and the bottom looks like it was dragged across sandpaper. Rough, textured, uneven, or covered in little bumps…
