    Re: HY CNC 3040

    Yes it can work as a 3 axis CNC, it depends on how you set-up the machine, I can work on metals on an ordinary LYCNC 3040, this unit is so overkill on doing just woodwork but it`s a future unit if...

    Re: CNC Router Aluminum Drilling Advice

    On my opinion if it`s a 24K RPM spindle and a 1/4 holes to be drilled, a 1/8 carbide single tool flute tool bit will do the job all day without resharpening the bit, ramp up the spindle speed to 24K...

  15. Re: Help with tips and with milling this bookshelf

    Re: How can I convert -24v NPN output to +5v?

    Opto isolators also can be used if you want just to switch +5VDC on and off using GND and -24VDC trigger, if you want a simplest form just use a 24VDC mini relay to switch the 5VDC on and off :)
