Hello,
does someone knows a controller board for LinuxCNC to control a lathe with step and direction servos what is connected to the PC with a usb or network cable?

Thanks

usb doesn't work with linuxcnc. Not realtime enough. There are a few ethernet solutions. The only one I am familiar with is mesa.

The 7i92 is like 2 high speed printer ports right out of the box. You can buy daughter boards that expand the i/o and add functionality.

the 7i76 is a ethernet+breakout board all in one.

7I76E STEP/IO Step & dir plus I/O daughtercard

gives you encoder interface / analog out for spindle + 48 i/o and 5 axis steppers outputs.

You could also look into ethercat, Linux cnc can use servo drives with ethercat.

Step/Dir can be run with a parallel port and a breakout board. I have a few machines running every day with this setup and with a lathe you have one axis less so there should be enough of channels for you. If you want to run a tool changer it depends on your setup if a parallel port is enough, you can add a second port if you want to stay on the cheap.

The Mesa 7i76E is an ethernet card for steppers.

jthorton is right but why do you need usb or ethernet ? my lathe and mills are verry happy without that - even the toolchangers. so where does that requirement come from ?

Hi,
I use UHUservo for the two axes, manually toolchange, two endswitches for every axe, two handwheels with A + B channel and a magnetic switch for spindle speed. For machining control I use a rugged Laptop with usb and network connector.

Thanks

The power saving "features" in most laptops make them unsuitable for real time control.

Though not ideal, some laptops _may_ be ok if you avoid certain operations

I have used my Dell E6420 for testing our Ethernet cards and it works fine with LinuxCNC as long as you never
change power modes (battery to line or line to battery) or adjust the display brightness/contrast with the function keys
these both generate multi- millisecond latency spikes
