PoKeys / Re: Triggering Pokeys Pin status through Modbus via Brains

Hi, Joe

The related pin should be setup as output, but no mapping should be configured in plugin configuration.

Hi, boutje

Due to some restrictions, PoKeys plugin for Mach3 supports 1 profile.

Two options:
- change A and B coil wiring for your y-axis stepper on the stepper driver
- use cncalex's hint

The spindle speed display is planned for Mach4 PoKeys plugin.

This will do exactly what you need.

Can the analog inputs be scaled in VFD settings? What range of VFD frequencies will you be using?
Namely, if you can setup VFD in such a way that 3.3 V on the frequency reference input means maximum spindle RPM that you need, then you only need to connect an RC filter (resistor and capacitor) to PoKeys output and connect the output of the filter directly to VFD.
If you really need 0-5V range, then you can put a 74HCT125 line driver (or some level converter IC), connected to 5V supply. This will convert 3.3V digital signals to 5V digital signals - you will need to put an RC filter to the output of this IC and the output of the filter to VFD.

If the VFD accepts analog input, then you can use PoKeys's PWM output to generate analog voltage reference.

Backlash compensation is not available when jogging. When executing the job, the PoKeys does exactly what Mach3 tells it to do.

Hi, Matthias

Which VFD are you referring to?

Hi, Tom

Currently, I am not in the office, so this will be a short answer.

1. Enable pin: connect this to GND, pin 7 is for error signalling purposes - you can either leave it unconnected or connect it to one of the pins and use your own logic in Mach3 to read it. All GND pins are connected, so it doesn't matter which one you use.
2/3. All pull up resistors can be made to 3.3 or 5 V (but to no more than 5 V).
4. Charge pump output is for boards that need/use it. You don't connect this one if simple direct connection to PoStep boards is used.
5. As all these wires are signalling wires, no special thickness is required. Keep the wires short and 'out of sight' of switched power lines. Regular flat cable in combination with 10 pin header connector is fine.

Regards,
Matevž
