After reading this post I’m still left confused. [image] My first CNC sucked - that's OK - how do I improve? Snapmaker 2.0 SimonF is spot on. If you’re trying to get 3D resolution, ball end mills are the way to go. If you’re just clearing material out, flat end mills sh…

What tools/tool sizes are you using for each path? The ones listed seem a bit excessive…

Yeah, those tool sizes are huge. If you’re using the correct SM configuration file it should warn you about coolant being ‘flood’. Just set it to disabled. I personally don’t like adaptive and use pocket. Adaptive is more clever about toolpaths and more efficient but it also kind of assumes you’re …

Are you actually using a 1/2 and 3/8 ball mill? Those are massive for what you’re doing. Also, they’re the wrong type. You should be using flat end mills. For reference, I use a 2 flute 3.175mm flat end mill for all my rough clearing.

Wouldn’t that take many many more hours? Even with the 1/2" thr roughing pass was over 3 hrs for the 12"x12" piece only going yo a max depth of 15mm. ~Don’t forget to be awesome!~

Yes and no. The SM is always going to be slow. 3 hours isn’t that long for SM. That’s a large and deep piece. 24 hours + milling time for all passes in hardwood isn’t unrealistic. With a flat end mill you can have a stepover almost the size of the bit. And a smaller bit you can run faster and cu…

For pine, with that 3.175 mm I mentioned, you could rip it at 1000mm/min at 1mm depth. That’ll cut your time down a good bit. [image] SainSmart Genmitsu 10Pcs Nano Blue Coat Flat Nose End Mill CNC Router Bits, 1/8"... SPECIFICATIONS Shank Diameter: 3.175mm…

sfj544 - fair enough. Thanks for your time & input.

With rest machining turned on, on subsequent passes it should start off where the last pass left off.
