[Emc-users] Question Regarding Selective Assignments in HAL

Hi All, I’m sure there’s a simple answer for my question, but I haven’t been able to figure it out. Currently the configuration for the spindle forward and reverse outputs is as follows: # connect spindle fwd/rev to I/O controller net SpindleFwd <= ppmc.2.dout.00.out net SpindleFwd => spindle.

Thanks Andy, I’ll play with HAL today and see what happens. Jon, you’re using the motion pins (spindle.0.x) while the "Spindle" component also has the same naming format and some of the same names. It took me awhile to sort it out. See this forum thread for clarification: https://forum.l

Re: [Emc-users] Question Regarding Selective Assignments in HAL

I’ve spent some time playing with the spindle component. It seems to have a number of bugs, beyond the issue with the documentation. Somehow a negative speed command multiplied by a negative gear ratio yields a negative speed. And the forward and reverse pins track the commanded speed, not th

Re: [Emc-users] Question Regarding Selective Assignments in HAL

Hi Andy, I might take a look at modifying the component. I’m comfortable with C, so perhaps I can work it out pretty quickly. I do like the spindle component’s concept, but it seems there are some issues. Nonetheless, fixing those issues might be a bigger project than I can handle when the p

Thanks again Andy, you answered my next questions. One final question. I see gearchange was rewritten but then the rewrite wasn’t put into the final release. I was studying the code revisions, which appear to solve some of my issues. Is this something that needs bug fixes and testing that ju

Re: [Emc-users] Question Regarding Selective Assignments in HAL

Also, after analyzing the code a bit further, it seems gearchange also has an error. The scale value (for gear 2, the "high" gear) is used to divide the speed in. This means that gear 2 is a lower gear, not a higher gear as the documentation indicates. I.e. gear 2 would be divided by the back
