01:35 PM Lcvette: machine is back up and running!
01:35 PM Lcvette: \o/
01:35 PM Lcvette: hurray!
01:38 PM TurBoss: hurray!
01:39 PM hazzy-m: Hurray!
01:44 PM Lcvette: \o/
03:39 PM Lcvette: i just was running testing on the wireless probe but am getting some false triggering
03:39 PM Lcvette: i tested the wired probe and there was no issue, it performs rock solid with no false triggering
03:43 PM Tom_L: noise?
03:45 PM Lcvette: also with the wireless probe it will move in the wrong direction sometimes, not sure if it is just due to a false trigger, or maybe the resistor is not the right size.. im seeing 5v and 19v between the gnd and signal wire and +24v and signal wire while untripped. do i need to have that closer to 0 and 24v?
03:48 PM Tom_L: what resistor?
03:49 PM Tom_L: i thought you said the resistor was installed already
03:49 PM Tom_L: the pullup resistor
03:58 PM Lcvette: this is from the 7i77 manual on the inputs...
03:58 PM * Lcvette sent a long message: < https://matrix.org/_matrix/media/r0/download/matrix.org/gKsuyQkXKHqdwjYZFqFAyjJh >
04:00 PM Lcvette: im currently using a 5.1k ohm resistor
04:01 PM TurBoss: put 4 of them in series
04:01 PM TurBoss: xD
04:01 PM Lcvette: :o
04:02 PM Lcvette: or use a 20k ohm resistor?
04:02 PM TurBoss: yup
04:03 PM Lcvette: you sure?
04:03 PM Lcvette: i don't wanna break anything again
04:03 PM Lcvette: lol
04:03 PM Lcvette: lcvette is frightened
04:03 PM Lcvette: :(
04:25 PM Lcvette: do i need 20k ohms?
04:25 PM Lcvette: seems high
04:30 PM TurBoss: in 5v i use 10k
04:31 PM TurBoss: sek i'm reading the 7i77 paste
04:31 PM TurBoss: ok
04:31 PM TurBoss: 20k ohm is bundled in mesa card
04:31 PM TurBoss: pulled down to ground
04:32 PM Lcvette: whats that mean?
04:33 PM TurBoss: The 7I77 field inputs have a nominal input resistance of 20K Ohms to field power
04:33 PM TurBoss: ground
04:33 PM Lcvette: sooo
04:33 PM Lcvette: doesn't need 20k ohms resistance?
04:34 PM TurBoss: do you have any docs of the probe?
04:34 PM Lcvette: only for 5v
04:34 PM Lcvette: it says use 5k
04:34 PM Lcvette: but im getting false triggers
04:35 PM Lcvette: i was speculating that maybe the threshholds are too close
04:35 PM TurBoss: maybe debounce?
04:35 PM Lcvette: needs more voltage gap
04:36 PM Lcvette: could be debounce
04:36 PM Lcvette: dunno
04:37 PM TurBoss: with halscope you can see the imputs
04:37 PM Lcvette: i can't watch the probe for estop and halscope same time
04:37 PM TurBoss: ya...
04:38 PM Lcvette: when it does something goofy sometimes it is in rapid move
04:38 PM Lcvette: and it doesn't make the clearance move
04:38 PM Lcvette: so can really get ugly quick
04:39 PM Lcvette: almost broke the probe on one instance
04:39 PM Lcvette: it probed the side then i guess it thought it should make a rapid move to the other side without lifting up
04:40 PM Lcvette: it does stop when triggered, but during a rapid move that isn't fast enough
