Yes, I did measure them with a professional micrometer, Few of them were 2.48 - 2.49 but the rest was exactly 2.50, so I don’t think that few smaller balls would make such a difference.

Small...

So…
A year ago I did an upgrade for my CNC with a new ball screw system. I bought it from the supplier in the UK, it was “made in EU ball screw”. I have paid quite of money.. Later on I found out...

Thank you ;)

Those are push buttons. But really easy to push down, I don't like that either. I had to add delay action to them, it needs to be pressed certain amount of time for action to take...

Finally finished and fully functioning hand controller.

Hi guys,

What type of couplings (motor-shaft) did you find best? I see now there's lot's of different types. For example:

Coupler GND zinc alloy flexible shaft couplings for micro motor and...

At first under "Config -> Ports and Pins -> Input Signals" in Mach3 I used Pin Number 10 for my MPG. And then I had problem exactly as stated in the first post. But I found out that Pin 10 is...

Okay, so I fixed it.

Config -> Ports and Pins -> Input Signals

EStop signal needs to be: Port #: 1 Pin Number: 10

Previously pin number for EStop was 13. But BL-UsbMach3 plugin somehow...

Hi dmcke5,

Did you find a solution?

I'm having exactly the same problem.

Cheers
