Hey, I was hoping someone here could help me because I'm losing my mind over something that seems like it should be simple. I'm a new machinist and this is my first time tackling knurling. I have a single wheel bump style knurling tool with a diamond shaped 20tpi wheel inserted. When stationary, the knurling produces is great, but any time I try to feed to make a larger knurl, it just comes out awful. I've played with feed rates, speeds, and depth of cut. I've gone online to look for answers but every source I find either disagrees with every other source and/or just doesn't work when I try their methods. The best I've gotten so far is the image attached. If anyone could give some advice or point me to somewhere that can actually help, it would be greatly appreciated. At this point I just feel like I'm running my head into a wall.

FlatCAM seems to be the goto software for 3-axys gcode creation. But it also seems to be abandoned code where only an old Windows installer remains and can't run on any modern system.

Is my reading of the situation right? Or there's something I'm missing?

hello all, I want to get into CNCs and wanted a recommendation for a starter machine mainly for acrylic I don't know much about CNCs but I am into 3D printing and 3D design so the software side shouldn't be too challenging

I work out of my apartment and I think 300x300mm is a reasonable size in case the information is useful

any recommendations and advice are welcome

I don't know what to write about it yet, since it still can't move on its own. 😅

This community is tiny, so I'll just post photos of the build now and then. When I've gained a bit of experience, then hopefully I can help others with their CNCs.

Combination of 3D printing and aluminum. Nearly all of the plastic bits are under fairly high compression to negate any slop. It's primary use is for milling circuit boards, but I would like to mill small aluminum parts as well.

I am going to use this one to mill better parts for another upgrade in the future.

I'm looking at buying the genmitsu 4040 pro swapping the spindle out for a Makita router I already have to initially make coins. Will this give me the detail that I see online from other makers?

Additionally, does anyone have tutorial recommendations for learning how to convert images for use with the above?

My old collector has been giving me issues, so I designed a new one that bolts into a 5 gallon bucket. It's easy to print, easy to assemble, and works very well. I've published it to thingiverse for others to enjoy. There are a few adapters published that include the HFT Bauer mini shop vac (for suction) and 1.75" utility hose that is standard to most regular shop vacs.
