  Thank you, also for staying objective even (or particularly) for a sponsored video! Mentioning the sponsoring in the beginning was much better!

  This was such an awesome review! A very clear and concise deep dive on what we could expect from this machine while offering some very good feedback for Makera to look at. <br><br>In my opinion, Makera have done a fantastic job at listening to what reviewers, and backers are asking for and I really hope they continue to push their product into being the best on offer for a long time running! <br><br>I was feeling a little concerned of the machine being underpowered for any future growth I have at home, but after your video, I am more than confident that it will be competent at doing what I need :) I am really excited for the future of CNC at home for makers!

  Aurora, can i give you some tips on toolpath programming and machining as someone who works with both professional and hobby machining equipment? I&apos;ve used equipment comparable to this (Carbide Nomad) to make mechanical parts from hardened steel and titanium.<br><br>You are creating toolpaths that are very old fashioned. Full width slot cutting at very slow feed rates with a very shallow depth. These toolpath choices result in making parts that are louder, less accurate, slower, and produce more wear on tooling. This old approach works best with older knee-mills that have tons of spindle torque, but not modern machines with high speed spindles. <br><br>Modern machining uses &quot;HSM&quot; (high speed machining) techniques. These techniques take advantage of the carbide tooling we have now as well as higher spindle speeds. <br><br>1. Machine much deeper. Aim for a depth of cut equal to the diameter of the tool. This means you arent putting all of the wear on the last mm of tool, helping tools to stay sharper for longer.<br><br>2. Machine much narrower widths. Try 1/10 the tool diameter. You should never cut a full width slot. Remember that the center of the endmill doesnt really cut - it grinds. See Saunder&apos;s Machine Works&apos; video on how to cut around a profile without full width slotting.<br><br>3. Increase your feed rate. Your aluminum feed rate should be around 1000 mm/min or more with this machine and a 1/4&quot; endmill at the DoC and WoC I&apos;ve incidcated.<br><br>4. You should only use single-flute tools with soft materials. Hobby-grade machines are not rigid enough to use single/zero flute tools with aluminum. Cheap chinese carbide from amazon tends to be poor quality, and you can get very affordable American-made carbide tooling on eBay from Kyocera or HTC. 2 Flute endmills produces the best chip size for our machines. <br><br>Too many flutes produces chips that are too small, cheating abrasive dust that ruins the finish and the tooling. Too few flutes creates significant vibration and makes a tool much less rigid, reducing tool life.<br><br>5. Stick with climb milling for any finishing pass. Our less-rigid hobby machines typically have less backlash but worse rigidity than old cast-iron frame mills, and benefit from climb milling.

  Excellent demo of this machine! I appreciate that you actually measure the achieved part size with calipers to check accuracy, something not everyone seems to do.

  Thank you very much for your excellent review. You are always putting so much work into every review. I would love to get into CNC milling if I would have enough budget.
