Hi i found that that scale is different. in emc2 2.2 theory was encoder pulses - in my case 8192 -- and that is per quadracha -- so x4--=32768 than ball screw about 5 pitch per 1" so times 5 and that get to around 163840 for scale. with 163840 i getting error. i increase that number to 1063840 and i can jog in 0.001 increment and consequently instead 0.001 machine moves 0.007 my question is - encoder with 8192 pulse is too old and i need servomotor where encoder output 10 times more pulse or get gear reducer head with ration 1to 50 etc?
i want to be sure that my ac servo motor (with 8192 pulse) tune able at all with emc2 -2.5 ?
