[Emc-users] Index-enable pin question
Hello! I am trying to help a guy that has retrofitted a lathe to LinuxCNC. He has 5i25 + 7i77 cards and 2.5.0 version installed. The problem is that I cannot figure out, how to get threading to work. G76 command will bring the tool along X to proper thread depth and then stop. It seems to me that it is waiting for a signal on motion.spindle-index-enable. That pin is connected to encoder.00.index-enable pin, I checked - there is index pulse coming from encoder every spindle revolution, but I do not see any pulses in Halscope on index-enable pin. I tried playing with index-mask and index-mask-invert parameters, but no success. This page does not seem helpful, explaining all the details on how to set it up: http://linuxcnc.org/docs/html/examples/spindle.html#_spindle_enable I see that reference no:2 at the bottom, but I was not able to find any explanation in manual. I would appreciate, if somebody could share some link, where it is explained, how exactly spindle index-enable pin is treated in lathe config. -- Viesturs -- November Webinars for C, C++, Fortran Developers Accelerate application performance with scalable programming models.

Re: [Emc-users] Index-enable pin question
I can't answer your question directly, but last night I was working to do the same thing and got it to work! I did notice the same behavior, moving to the proper X and never starting. For me the problem was that I was using both phases A and B, and that the encoder was counting down, not up. Reversing A and B fixed the problem. Maybe this will help you too. -Kip On Mon, Nov 11, 2013 at 6:35 AM, Viesturs Lācis viesturs.la...@gmail.comwrote: Hello! I am trying to help a guy that has retrofitted a lathe to LinuxCNC.

No, other that it can only be connected to another IO pin. It's easy enough to test. I think that you can even sets the signal without halcmd complaining Then watch the value in halmeter, it should go false then the index passes the sensor. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- November Webinars for C, C++, Fortran Developers Accelerate application performance with scalable programming models.
