Ok, Lets make it easier for me to understand:
1. Can you suggest servo and its controller working on my dell 640m laptop running linuxcnc-wheezy? 2. As far as I know parallel port is something like LPT1 port for old version of printers but nowadays we can't find LPT1 ports only USB port and HDMI available. Is there any other way laptop as cnc routers communicate to servos and drive spindle motor let say making 3 axis vertical miling machine. 3. I live in Indonesia, are there any LinuxCNC hobbyist nearby? thanks Riza On 08/04/15 03:37, Philipp Burch wrote: > Hi Riza! > > On 07.04.2015 22:11, Abdul Rahman Riza wrote: >> Dear All, >> >> I just Installed built in LinuxCNC integrated with debian wheezy under >> my Dell Inspiron 640M laptop and I have several unused servomotor to >> start with. >> >> My question: >> 1.
