LunixCnc

[gemmi8]

Is anybody using LunixCnc? if so can I ask where you got your CNC control board because I believe I have to have the parallel port access? And if so any information as to how to set the board up would be very grateful. I am using a spindle and would love to have it controlled with the speed by the computer.

Linux CNC can be something of a bear to set up. There are a few ways to "do" Linux CNC, but you are talking about a pretty serious undertaking if you wanted to convert to that. You would be better off just running it via PWM signal from the boards you already have. We don't cover how to do this as it's a bit in depth, but the basics of it are you flash the Uno board to run a version of Grbl that generates a PWM signal (we could post that). You'd then have to take off the hand wheel and run a line from PWM to the PWM input on the spindle control board.

If you could post the info for the UNO that would be great. I'm doing with the Christmas order rush so have some time to mess aroind with it. Since the control board has a USB hub should I just buy a new control board that has a parallel printer port? I would appreciate any information with this I would like to be able to have more control over the machine.

Hey Gemmi,

You'll have to search the forum some for any more extensive documentation on the spindle PWM setup. It's not something we cover.

This is the hex file for it. Note that the Z switch will move to PWM and the PWM funtion will be on Z+ after you flash this file. That sounds weird, but it is correct.

You'll need to load it with Xloader.

I think the input speed signal voltage to the motor drive is 0-10vdc. The output of the control is 5vdc. You will need to convert the signal from 5 to 10vdc. www.amzn.com/B0725QFZSS
