PoKeys / Spindle VFD feedback
« on: November 12, 2016, 07:13:30 AM »
Hi there!!!

I own a chinese 800w VFD since 2012 and running like new, now I have a new cnc ethernet controller, I am already able to controle the spindle speed and start/stop from Mach3 but I would like to have the rpm feedback from the vfd into the mach3.
As the VFD screen shows the current rpm of the spindle, how can I get that info, which are the pins on the vfd and what time of signal is it? Pwm or analog?

Thanks

PoKeys / PoKeys57CNC vs SmoothStepper
« on: September 02, 2016, 03:54:35 AM »
Hi guys,

I have been working with a cheap cnc machine for the last 4 years and now its time to step up so, I am going to build a bigger and more robust and more precise machine.
After seeking for CNC controllers, I found the Smoothstepper and the PoKeys57CNC among others.
My biggest question is, which one of these two you would recommend? Keeping in mind that I want a stable and precise system as I mill aluminium.

In terms of motors, I'll jump into servo motors with encoders but I'll keep my chinese VFD / spindle for now.

Thank you

Regards.

Modbus / ModBus, not more than 63 lines of cfg#????
« on: October 28, 2015, 02:08:32 PM »
Hi there,

I am building an interface for my cnc using the modbus plugin and 2 arduinos, one for inputs and the other one for the outputs.
I have noticed that the modbus plugin does not allow more than 63 lines of cgf commands but I need more than that.

Is it possible to increase this?

Thank you

Regards
