03:21 PM skunkworks: what if you want to run a bit away from the home switch so that there isn't a chance (sloppy machine) that the home switch gets triggered? If I set the home offset to -.05 and home to 0 - my soft limits are 0 to 24.
03:21 PM skunkworks: it homes but I get a soft limit exceeded error while homint
04:10 PM seb_kuzminsky: skunkworks: i dont think you can have your home switch outside your soft limits
04:11 PM skunkworks: seb_kuzminsky, darn. that's ok. I will deal
05:08 PM jepler: make your soft limit extend to -.01
05:08 PM jepler: the home should be strictly within the soft limits, not equal to one of those limits
07:15 PM skunkworks: jepler, I will give it a try. I had tried -.005 min limit as a try - but it still gave a soft limit violation
07:15 PM skunkworks: (but still homes)
07:24 PM jepler: skunkworks: I see. I thought soft limits went applied until the move to home was complete but maybe this is false.
07:24 PM jepler: or maybe it changed due to JA?
07:25 PM jepler: I dunno for sure and I didn't investigate before opening my mouth
07:35 PM skunkworks: I am using 2.7.mumble
07:35 PM skunkworks: I can setup a sim and play with it
07:36 PM skunkworks: I thought maybe there was a pin to ignore softlimits that I could use by homing.. But I didn't find any
07:56 PM cradek: argh, today I learned there are about a dozen ways ceiling fans get 3 speeds, and they all take a different switch
08:47 PM skunkworks: I bet it cost less to get a whole new ceiling fan...
08:47 PM skunkworks: I am sure it could be done with a beagle bone...
08:49 PM cradek: if I understand what I have (the wrong switch) it will give me H, L, L with no medium
08:49 PM cradek: but it seems like high isn't very high (never has been) so I might have bad capacitor(s) too
08:49 PM cradek: it's an extra quiet fan (and it's true it's quiet, but is that quietness guarantee why it's so wimpy on high?)
08:51 PM cradek: omg http://kenklaser.gaiastream.com/2007/12/28/ceiling-fan-capacitor-solutions/
08:51 PM cradek: an actual engineer had the same annoyance
09:18 PM jepler: skunkworks: it seems to work for me like I expected, though I chose big tolerances https://emergent.unpythonic.net/files/sandbox/0001-for-sam-switch-outside-of-soft-limits.patch was what I changed in sim/axis in master branch
09:18 PM jepler: home switch at -1, min soft limit at -.5
09:18 PM jepler: .. home at 0
