STM32Fdiscovery and Linuxcnc I am also working with! I have started with the VFS11 driver and have communication using modbus via ethernet which is a starting point. I also have suitable experience working with frequency converters for electric motors and a university degree with suitable courses for this kind of work.
At first I should get it up and running for two EDM machines. Then this is done improvements is planned.

Manually upgrade your production database. When you want reliability, choose Perforce Perforce version control. Predictably reliable. http://pubads.g.doubleclick.net/gampad/clk?id=157508191&iu=/4140/ostg.clktrk _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
