HELP - router makes incorrectly shaped radiuss

[routerdriver]

My guess would be movement or deflection of some part of the router.I would suggest you try cutting two identical parts-one using conventional cutting and one using climb cutting and see how they compare.

[indulisap]

the servostepper has 200 steps per revolution, the encoder 1000 pulses per revolution.
HBS86H I have selected 1000 PULSES PER RPM
There are 250 pulses per mm displacement along X and Y.
