Review: Engraved and cut miniature nameplates in brass - I researched the various machines on the market at this time (April 2025) and decided on the ComMarker B4 50W as being the best value, and bought it from desertcart as being the least commercial risk. It arrived a week early, in perfect condition, and has worked brilliantly. Its taking me a little time to find the best settings as I am also learning Lightburn at the same time - so a steep leaning curve! EzCad was an issue as it said it was a Demo version, even though it was registered to me.... however, I was never going to use it.
Review: Nice bit of kit - This is powerful. Best thing i have ever bought. Easy to use, accurate and well built. Expensive but definately worth it.
