Two things set the numbers on the MakerMade M2 CNC: how fast the User-Supplied Router spins, and how much the frame can take without chattering. It runs a working range of about 10,000 to 30,000 RPM, on chain and sled system (improved from maslow). The MakerMade M2 CNC has a lighter frame, so shallow passes and patience beat trying to hog material in one go.
So for a 1/4" two-flute bit in softwood, a sensible starting point on the MakerMade M2 CNC is around 17,000 RPM and 102 inches per minute, taking about 0.06875" per pass on a slot. The full chart below covers the materials you are most likely to cut. These are conservative starting points: always test on scrap and let your ears do the final tuning.

| 1/4" | 17,000 | 102 ipm | 0.069" | |
| Hardwood | 1/8" | 30,000 | 90 ipm | 0.017" |
| 1/4" | 20,000 | 100 ipm | 0.034" | |
| Plywood / MDF | 1/8" | 25,000 | 100 ipm | 0.034" |
| 1/4" | 17,000 | 102 ipm | 0.069" | |
| Acrylic | 1/8" | 25,000 | 100 ipm | 0.026" |
| 1/4" | 13,000 | 104 ipm | 0.052" | |
| HDPE / Plastics | 1/8" | 17,000 | 102 ipm | 0.026" |
| 1/4" | 10,000 | 100 ipm | 0.052" | |

| 1/4" | 25,000 | 100 ipm | 0.017" |
Numbers are generated by our feeds and speeds calculator using the MakerMade M2 CNC's spindle range and a light-frame rigidity factor. Aluminum needs a single flute plus lubricant. Always confirm your bit maker's chart and test on scrap.

What RPM should I run on a MakerMade M2 CNC?
For most wood with a 1/4" two-flute bit, 17,000 RPM is a good starting point on the MakerMade M2 CNC. Its working range is about 10,000 to 30,000 RPM. Go higher for smaller bits and finer detail, lower for big bits and heavy stock removal.
What feed rate should I use on a MakerMade M2 CNC in hardwood?
Start around 100 inches per minute with a 1/4" two-flute bit in oak or maple on the MakerMade M2 CNC, at roughly 20,000 RPM. Listen to the cut and adjust: clean chips mean you are dialed in, fine dust means you are going too slow.
Can a MakerMade M2 CNC cut aluminum?
Aluminum is a stretch for the MakerMade M2 CNC. Its frame is on the lighter side, so if you try it, use a single-flute bit, very shallow passes, lots of lubricant, and low expectations. It is happiest in wood and plastics.
