The scale factors are numbers that represent the smallest increment that can be distinguished per unit length. They're used to inform the software of how much linear distance corresponds to the distance between encoder markers.
Scale factors are printed on the front leg of all routers.
Scale Factor Setup
Scale factors can be changed by going to Setup > System, and changing the M1 through M4 scales. A negative sign indicates direction.
Scale Factor Interface Setup (pdf)
- Click on Setup > System
- Find the "Mx Scale" section.
- Change the Scale Factor(s) to the correct value(s) for the machine. See the Scale Factor label on the gantry or front leg for details. Otherwise, see below for a guess.
- Click "OK" to save change
If the scale factors are unavailable, try the following values, depending on your machine:
LC
- All axes: -20320
LC plus
- M1: -12192
- M2: -7620
- M3: -20320
RG
- M1: -10160 (most) or -12192 (59"x50")
- M2: -7620 (newer) or -5080 (older)
- M3: -20320
Premium Class
- M1: 10160
- M2: 5080
- M3: -20320
If none of these values work, please check your measurement device. Try measuring over a larger, or shorter area for verification.
Manual Scale Factor Generation
If you are still having problems, perform the following operation:
- Using calipers, measure exactly how far the machine moves when you use jog step to move the machine 1 inch.
- Take the current scale factor value, and divide it by the result you just got. (i.e. 20320 / .9")
The resulting number is the correct scale factor. Repeat this test until you achieve the desired accuracy.
