Let me tell you, the E-Leveler 2 has completely transformed my 3D printing workflow. As someone who's spent countless hours fiddling with paper leveling, this little gadget feels like magic. The moment that LED light turns on when your nozzle is perfectly positioned? Pure satisfaction.
The improved design really shows - the battery holder is sturdy, and those reminder arrows are genius for beginners. I particularly love how the balancing end cap keeps it steady during adjustments. No more wobbly tools throwing off my measurements!
Now here's the real talk: while it's incredibly accurate (way more consistent than paper), there is a learning curve. Positioning under the nozzle target takes some practice, and like several users mentioned, you might need to tweak your Z-offset by about 0.15mm after initial setup.
The compatibility across printers is fantastic - worked beautifully on my Ender 3 after struggling with manual leveling for months. That said, if you've got a printer with auto-leveling already, this serves better as a fine-tuning tool rather than a complete replacement.
Pro tip: Modify your gcode to pause longer at each leveling point. The standard pause time often isn't enough to get perfect adjustments.
Is it perfect? Almost. The red cap could be more secure, and the target area could be more visible. But these are minor quibbles compared to the time and filament this tool saves me weekly.
Final verdict? If you're serious about 3D printing and tired of inconsistent first layers, this $20 tool will pay for itself in saved time and reduced failed prints within your first few projects.
