08:52 PM Tom_L: test
10:25 PM rue_shop4: the saturation voltage of that 4301 driver is 1.5V
10:25 PM rue_shop4: the application runs 2 coils at once
10:26 PM rue_shop4: the power limit is 4.4W
10:26 PM rue_shop4: so,
10:27 PM rue_shop4: current of 2.9A average
10:27 PM rue_shop4: I'm using pwm,
10:29 PM rue_shop4: no
10:29 PM rue_shop4: half that
10:29 PM rue_shop4: thats why they keep using 1.5A in the datasheet
10:39 PM orlock: Pretty much finished the mounting plate/adaptor to put the CN controller into a telescope
10:39 PM orlock: CNC, even
10:40 PM orlock: just need to chase down the pinouts of the board and make the code changes
10:48 PM rue_shop4: those 4301 suck
10:52 PM orlock: rue_shop4: Splicer isnt working yet
10:52 PM orlock: I need to drill a hole for a temp. sender
10:52 PM orlock: Guessing "is it hot enough" is just too hard
10:53 PM orlock: if that fails, i think there's some sort of skin effect happening
10:53 PM orlock: like a dry solder join
10:53 PM orlock: as the join is very weak, it pops apart under the slightest pressure
11:27 PM rue_shop4: interesting, keep in mind, I always have to do mine twice, like some kinda skin effect
11:27 PM rue_shop4: orlock, you work for a stepper motor company, right?
11:27 PM rue_shop4: or am I mixed up again
11:44 PM orlock: Sort of
11:44 PM orlock: Not really
11:46 PM rue_shop4: k
11:46 PM rue_shop4: I dun cum up wit a unipolar motor driver crrrcuit :D
11:46 PM rue_shop4: I was wondering if you had anyone you could flash it at and see how they rate it
