I have a 40W CO2 laser and it takes 3 passes at full power. Am I doing something wrong or do I need to upgrade?

Tried dry moly lube, mustard, Cermark, and laser bonding spray. Here's my honest comparison after 6 months of testing on various SS grades.

Started as a one-off for a friend, ended up doing 100 orders! Learned so much about batch production and file organization. Happy to share my workflow.

I've been keeping a spreadsheet since I got my first laser. Sharing all my settings for MDF, ply, acrylic, leather, felt, and cardboard.

Budget is around $800. I mostly do wood engraving and some acrylic cutting. The S1 seems amazing but the K40 has a huge community. Thoughts?

Got tired of fumes. Used 20x20 aluminum extrusion, polycarbonate panels and a 4" exhaust fan. Total cost: $118. Plans available if anyone wants them.

Edge-lit 3mm clear acrylic with a RGB LED base. Client wanted their business logo. They ordered 12 more after seeing the first one.

Was fighting Z inconsistency for months. Turned out to be a loose eccentric nut on the Z-axis wheel. Sharing the fix because I couldn't find it documented anywhere.

If you're getting horizontal bands on your tumbler engravings, here's the fix: it's almost always your rotary roller speed not matching the linear speed. In LightBurn: go to Device Settings > Additional Settings and set "Rotary Scale" based on your tumbler's circumference. Formula: (360 / tumbler_circumference_mm). Once I got this right, zero banding.

Cutting 600x400mm pieces from 6mm ply and the corners always lift. I've tried tape but it's not enough. Any tips?

I design quick 3D-printed positioning jigs for repeat jobs. Cut 20 identical pieces in half the time. Anyone else doing this hybrid workflow?

Cast acrylic vs extruded acrylic behave completely differently. Here's how to tell them apart and the settings for crystal clear edges on both types.

Just got my first diode laser (xTool D1 Pro). Total beginner here. Is Lightburn worth the $60 or should I start with the free option?

Replaced the stock MDF with a custom piece that has T-slot channels every 50mm. Total game changer for workholding.

Print-in-place hinges that actually work without breaking: Layer height: 0.15mm. Gap between hinge pin and hole: 0.3mm. Temperature: 205°C for PLA. Speed: 30mm/s for the hinge area. Cooling: 100% fan at layer 2. I use a 0.4mm nozzle. Works on Bambu Lab and Prusa. The key insight: print the pin vertically for strength.

Bamboo cutting board + 2 hours of engraving work = one very happy bride. The detail you can get on bamboo is incredible.

2-flute 1/8" end mill, Shapeoko 3. Tried 18k RPM, 600mm/min, 0.3mm DOC and it sounds angry. Is aluminum just hard or am I doing it wrong?

Cermark is expensive. Looking for alternatives that give good frosted glass results on a 10W diode laser. Has anyone had success with the baking soda paste method?

I love FreeLaserFile but I always want more options. What are your go-to sites for free DXF and SVG files? Specifically looking for geometric patterns and nature/animal designs for a series of wall panels I'm making.

I've seen conflicting advice. Some people swear by it for preventing flash marks, others say it affects the cut quality. What's your experience?
