I think I've seen this sort of function called 'backplot' on machines I've used. Jim On Sun, Nov 18, 2012 at 6:07 PM, Chris Morley wrote: > > > >> From: marcus.thebowm...@virgin.net >> Date: Sun, 18 Nov 2012 22:50:46 + >> To: emc-users@lists.sourceforge.net >> Subject: Re: [Emc-users] linux

Chris, I can't see the EDIT button on that Whiteboard. I have logged in etc but it remains Read-only. How about a simple "simulation" button? That's different from the Cutting simulation. I envisage the code running and the backplot window showing the result, without attempting to simulate th

[Emc-users] 0-10V spindle control via Mesa 7i33

2012-11-18 Thread Scott Hasse
All- My Sieg KC4S lathe conversion is moving along, and I have a question about driving a spindle motor controller using a Mesa 7i33 servo controller. According to the docs, that daughter card uses sign/magnitude mode , which will generate 0 to +10V analog out when the direction is positive and 0

[Emc-users] mesa 7I43 + MPG + speed control rotary switch

2012-11-18 Thread Matthieu Patou
Hello all, My father and I are trying to hook a MPG + a speed control rotary switch to a MESA 7i43 and it seems not to work as expected. The rotary switch has 4 position to control speed increment. We tried the configuration in PNCconf and we stumble into the following issues: * most of the ti
