Spindle Calibration ESS
« on: November 03, 2015, 09:43:09 AM »
I am using a C6 Spindle Speed control board (cnc4pc) to control my VFD.  I can't get my spindle calibrated.  It will spin CW and CCW and will even change speeds.  The problem I am having is getting it calibrated, I am using step and direction so I'm using an OB motor, however, I have found that my spindle will still turn on and change speed even when the motor I have attached to it is turned off. 
I'm going to attach the ini, in it the OB Motor is not turned on that is attached to the spindle config.

I was having a similar problem but the suggestions in this video helped me solve them.

Do you mean that in the Configure->Mach dialog on the "Motor" tab you un-check, say, "Motor3" to disable that motor.  I've found that Mach4 can ignore this setting and will still generate motion on that motor if it is still assigned to an axis.  For example, say Motor3 is disabled in the "Motor" tab, but in the "Axis Mapping" tab Motor3 is assigned to OB1 and OB1 is enabled.  This was still the case in build 2763.  I haven't tested this with newer releases.

If that is not what you mean, well then never mind.

In the axis mapping I uncheck the OB motor I'm using for the spindle.  It will still turn on, M3 and M4, and change speed.

If you un-checked the axis enable, then I would *guess* that the ESS is ignoring that configuration and using something in its own plug-in configuration dialog(s) somewhere.  But that is the extent of my "ESS under Mach4" knowledge.
