Re: [Emc-users] estop writes to toolchange pin out? more testing
Please make sure you are running the latest version of emc, which is currently emc 2.1.5. It includes "fix for bug 1701900 - spindle does not turn off when going into machine-off state".

I think that's the only one that's not strictly related to the EMC2 install. To see the input filters that do other fun stuff, be sure to run sim/axis and open an image file or python file (both are available in the sample files that come with the distribution).

[Emc-users] TrueType Tracer
I found and downloaded this nifty looking program (truetype-tracer_3.0-2_i386.deb) from Chris Radek's web page. When I went to install it on a recently installed EMC2 Live system it tells me the program is already installed. So :( how do I run the program!!?? I found the executable but it seems reluctant to run. And is there a list of all the little programs like this that come with the live install? Andre' B. __ Andre' B.

Of course, you have to have an encoder on the spindle. And, you have to provide a way to feed this encoder information back to the computer. We first demonstrated this capability at the 2006 CNC Workshop. I demoed my mini-mill pretending to be a lathe at the 2007 NAMES show last month. I had some strange driver/interface problems that are now fixed, and it works like a charm. I have a set of config files on my web site that show how to do this using my universal PWM controller : http://jelinux.pico-systems.com/codes/univpwmthread/ Without that hardware, you would need to assign parallel port pins for the encoder input and use the software encoder HAL component.

Re: [Emc-users] I/O card recommendations, please?
Oops Ray credited us with a feature the PMDX-122 does not provide. The PMDX-122 is buffered and will run Gecko drives even from a 3.3 volt parallel port, but it DOES NOT provide optical isolation for the input status signals. These signals do go through a buffer on the PMDX-122 that will, in most cases, protect the parallel port from damage due to signals applied to the status inputs. It does not isolate ground and thus cannot protect against damage due to external voltages arriving through the ground connection. Likewise for noise from equipment such as plasma cutters. The folks at CANDCNC.com do offer an less expensive MiniIO card the does provide optical isolation, though you must buy another accessory card if you also want a relay.

Right now, only a spindle with encoder and index pulse may be used. The "index pulse" gives one pulse per revolution, and the rest of the encoder signal (called phase-A and phase-B) ensures that emc is aware of the orientation of the spindle at all times. I think that the nist-lathe has a 1024 count per revolution encoder, which allows emc to know the angle to within about 1/3 of a degree.

Re: [Emc-users] I/O card recommendations, please?
Hi Pat. Long time since we've heard from you. Glad to hear that you're using EMC2 and that it is working for you. I've tried a lot of breakouts and the maker you mention is as good as they come. The PMDX-122 is about as low cost as you find for fully isolated. You might get away with just a screw terminal breakout if the stepper drives you're using will handle raw parport output. Note that Gecko drives will NOT work with a 3 volt parport sig. They will work with some PCI parports that put out 5 volt. A search for "parallel port breakout boards" will get you a list of 'em in just about the order I've worked with them. The only one (passive) that I don't see there is a ziplink din rail mount from automation direct. Hope this helps. Good luck. Report back with your progress and (hint) add a page to the wiki with your projects.

Re: [Emc-users] Lathe Threading in EMC
Thanks, I'll try the nist-lathe config. Does the index output need to be one pulse per revolution? Can it be similar to what there is in mach2 program: several pulses per rev with one pulse wider than the others.
