Q & A?
Could it be modified to a larger range? What's the accuracy if the arm part is extend?
The below picture in Blue frame: To extend the arm part, the extension will weaken the arm motor braking capacity and start-up capacity,the load will be reduced to ensure performance, accuracy will be reduced too.Round trip accuracy:+-2mm
