Re: EMC & Linux
Sorry, I forgot to tell you. I believe this fixes the problem of DEFAULT_VELOCITY not affecting the default feed rate. It also may limit the max feed rate to MAX_VELOCITY. Fred told me this on Friday,

Re: EMC & Linux
Tim, I have been running EMC this week on a Sherline mill. I haven't made any parts yet, but have been running the table to get a feel for it. On G02, G03, cirular interpolation- I have been using

Re: Term: Mag Amp
Thanks Jon but let me just get it clear. Are you saying that if you put, say, the high voltage winding of a mains transformer in series with the low voltage motor, it will boost its starting
