The router has numerical speed settings, my tools call for a spindle speed of 18,000 rpm. Does anyone know how to determine how the numerical settings relate to actual spindle speed?

It’s in the manual and also has been discussed many times on this forum. [image] Makita Router Tach Speeds Machines (Original/PRO) Posted this over in the FB group, and posting here also. I put a tachometer on the Makita to see what the real speeds were, hopefully this ca…

Hey Gerald, hey Nick, [image] ConvenientWoodwork: It’s in the manual I have this little pic of it: [Maktia_RT0701C__Speed_Adjusting_Dial] Source: Makita RT0701C trim router’s Instruction Manual

I tested mine with a tachometer and it agreed with the table, within reason. If you are concerned you can buy your own tachometer. Mine has reflective tape you put on the router nut, and it counts the number of revolutions per minute. Very simple, not very pricey. I think I got it from Amazon.

Thanks very much, I never thought to look in the manual. My mistake, at any rate, I really appreciate the reply. Kind regards, Jerry

That’s really great information. Not too terribly concerned, but after researching it a little, it became apparent that it’s not an even progression, by that I mean, the spindle speed at 3 is not half of what it is at 6. I’m about a week old at CNC routing and I’m trying to follow the speeds suggest…

It looks very linear between settings 2 and 5 (which is backed up by Jake’s tachometer data posted on these forums). Thanks to everyone (Andy, Jake, Aiph5u) for this important info.

I am going to modify my Fusion360 post processor to tell me which dial to set the router too. Here is the simple formula, X is RPM speed Y is Makita Router Setting Y = 0.000231X−1.0338 Probably also want to round the result to the nearest 0.5. [image] Might have to go polynomial, but I think…

[image] suprak: I am going to modify my post processor to tell me which dial to set the router too. That’s pretty cool. Right now I add the router speed setting to the description in my tool setup in VCarve. Then I include that in the toolpath name so when I load the toolpath it’s telling me…

Alex, the line in “Replace with” is identical to the line replaced! Did you forget something or am I just not seeing it?

Hey Chris, you got to scroll code line horizontally :slight_smile:
