I agree nice work. Thanks! I pulled the tar.gz file, compiled it and it is running very nicely on Ubuntu 9.10. :-) I'll test it on a machine tomorrow. Dave On 5/9/2010 3:20 PM, Sven Wesley wrote: > 2010/5/9 Jeff Epler > > >> I'm pleased to announce the first stable release of the

From what I have seen having the line NML_FILE = emc.nml causes an error on 2.4 and later, while it is required in 2.3.5 and earlier. So yes. That line should be removed from all of the example .ini files as far as I can tell. Dave On 5/9/2010 8:46 PM, Cal Grandy wrote: > OK, OK Follo

[Emc-users] stepper spindle?

2010-05-09 Thread Ian W. Wright
Is it possible to configure a stepper as a spindle motor and if so - how? I have a little lathe set up as a rotary axis with stepper motor drive and it would be very useful if I could arrange it so that the spindle optionally worked (using another config file) as a normal lathe spindle. I have

[Emc-users] Starting spindle with F9 with spindle speed DAC

2010-05-09 Thread Jon Elson
Hello, all, I just added a DAC for spindle speed control to my Bridgeport. For years, I just had forward and reverse contact closures to the VFD and a manual speed pot. Now, I have a DAC channel from EMC to the VFD. I can start the spindle with an MDI entry like M03 S2500, but when I try to

[Emc-users] OT quick question on sizing flyback diodes.

2010-05-09 Thread Greg Bentzinger
I'm putting a small H-bridge together using TIP121/126 to replace a SN754410NE. The schematic I'm following didn't list any values for the flyback diodes. In fact some examples left them out. I know that when this circuit is in use it switches from full forward to full reverse with no ramping. T
