It does not answer your question but it is usual to ignore Pin1. The motor outputs are usually set as X Step & Dir 2-3,  Y 4-5,  Z 6-7,  A 8-9

On the Settings page you will find the Axis Calibration feature - use this to check that you have the Steps Per Unit set correctly for each axis.

Mach4 General Discussion / Re: Mach4 spindle setup

All I want is for the machine's rpm to match commanded and actual. I.e. When I command m3 s1800 and measure the actual rpm using a tachometer it matches pretty close, not off by a few hundred rpm.

I understand your frustration but it is not a Mach4 problem and it is not an ESS problem.

The problem lies in whatever connects the PWM output from your ESS to your spindle motor and these are perhaps the areas in which you should be testing.

1) Is the analogue voltage output from your C32 BoB (0 to 10 Volts) linear to the Mach4 commanded S#### ??

2) Does your VFD have linear response (output frequency) when driven by a regulated 0 to 10 Volt standard ??

I reloaded mach3

Perhaps re-post your .xml file (the one from your Mach3 folder) now that you have reloaded Mach3. Copy and rename it to kharrison2.xml for posting.

Could you have posted the wrong .xml ?

This is certainly not right for the Z axis config.

I will look at it in more detail but from initial observation...

In Config. / Motor Tuning you need to set Steps Per Unit, Velocity and Acceleration for your Z axis.

If it's any help, the relationship between the Mach4 S#### command and the PWM output from the ESS is completely linear. If you are not getting correct RPM readings over the total speed range then the problem is located in the items between the ESS and the spindle.

Post your .xml file ( the current one from you Mach3 folder ) copy and rename it to something unique (kharrison.xml) then use the Reply and Additional Options tabs to attach it.
We will then be able to check your settings and perhaps be able to suggest the way forward.
