Hi! I try to use it. Work still in progress, but control part is almost done. please read more here http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,16/id,2056/limit,6/limitstart,12/lang,english/#14554 On 11/08/2011 06:15 AM, Kasey Matejcek wrote: > Has anyone tried to use and RC controller with EMC to run a RC brushless > motor > They take a pwm control signal from 1ms to 2ms or around there but haven't > tried > It sound like the have to have a signal on the input when there powered up > or the go into disable mode possibly > >> On 7 November 2011 02:26, Kirk Wallace<kwall...@wallacecompany.com> > wrote: >> >>> I suppose a draw >>> bar is going to be a problem. >> >> How does your current drawbar work? >> I can imagine thet it might be possible to use the exisiting drawbar >> actuator for the new spindle.
