Enhanced Ox CNC and Spindle RPM reduction issue

[TheMike]

Thanks for your response. The wiring is all correct as the spindle spools up smoothly as before but seems to top out at a lower RPM. For further info, the wiring was about 1.2m in length, now extended to about 2.5m.

I lack some electrical knowledge. Which pins on the speed controller should I measure between to get the voltage reading mentioned above. And should it result in being lower than the 10v suggested, how would I go about boosting it? The speed controller itself is supplied with 48v.

Many thanks,

Well to be fair if your not electrically minded then I suggest you don't mess around because depending on the Speed controller type the voltages can be at mains potential and dangerous if poking around not knowing what your doing.!! Suggest you try to find someone electricly savy to help with this.
