lucascastro: I am still searching for another motor and another BC547...
<
set_>
I know I had one around here somewhere. I may have to outsource.
<
lucascastro>
but the transistor is ok, you should measure the A+ A-, B+ B- output, if nothing out there
<
lucascastro>
the motor should be the problem
<
set_>
voltage and/or ohms or another test?
<
set_>
I found another motor and a BC547 for the step pin.
<
set_>
I guess the driver is bad.
<
set_>
I bought three bad drivers.
<
set_>
So, 0.0v at A +/- is normal?
<
lucascastro>
The led between the transistor and port
<
lucascastro>
is blink, right?
<
set_>
They say enable from controller and OPTO from controller too.
<
set_>
On that link, they are saying the negative and positive are connected to the EN and OPTO.
<
set_>
But, that is from the controller they are saying.
<
set_>
damn it. I think everything is fine. My bench supply for power and GND is starting to give me issues.
<
set_>
I will try another route.
<
set_>
This motor is heating up too.
<
set_>
No clue now.
<
set_>
This driver is making me dumber than most days...

<
set_>
anyway. no issue. I will get a different driver...
<
lucascastro>
the motor is heating up?
<
lucascastro>
so there's current over it
<
lucascastro>
my idea it was disconnect the motor and check it'll detect voltage where the motor is plugged
<
lucascastro>
if true is going everything fine and the motor is the problem .
<
set_>
I am testing anoter route right now. I will return service soon. I am not using the BC547 right now and using EN and OPTO.
<
set_>
as soon as a run the simple file, PY file, the PSU shuts down.
<
set_>
Then, I stop the PY file from running and the PSU starts up and runs fine.
<
set_>
I give up for now. I am beat.
<
lucascastro>
and runs?
<
lucascastro>
the motor?
<
set_>
The motor never turns.
<
lucascastro>
got it.
<
lucascastro>
if you make another try, just measure the output voltage to the motor.
<
lucascastro>
with the motor disconnected
<
set_>
So, I run the source with the motor disconnected and measure the output voltage.
<
set_>
I will do it.
<
set_>
I am getting 0.3v on this driver.
<
set_>
on A +/- and B +/-.
<
set_>
let me switch the source...
<
set_>
So, I switched the source to on and toggle.
<
set_>
The GPIO12 on the Y-AI is an ON switch via the OPTO and GND to ENABLE from the Y-AI.
<
set_>
GPIO12 = ON = OPTO && GPIO6 = GND = ENABLE
<
set_>
Sorry. That is incorrect.
<
set_>
GND on controller is ENABLE on the DRIVER.
<
set_>
GPIO on controller is OPTO on the Driver.
<
set_>
That should set the driver on/off.
<
set_>
Then, I have another GPIO on controller that toggles the Direction without Stepping.
<
set_>
The A +/- on the driver is 0.3mA.
<
set_>
The B +/- on the driver is 0.3mA.
<
set_>
I should have about 600mA right?
<
lucascastro>
What is expected. When the GPIO is HIGH, the motor should torn
<
set_>
I expect the motor to turn when the ENABLE is ON and the DIR is I/O.
<
set_>
Is this a falsehood?
<
set_>
I mean, I am incorrect thinking this will work?
<
set_>
I will try the PUL pin next. I do not think it is the controller. Let me test the controller too.
<
lucascastro>
I don't know about the driver.
<
lucascastro>
not exactly
<
set_>
Me neither. The more I read and reread, the more I think they are guessing...
<
lucascastro>
review the paper
<
lucascastro>
I guess should signaling on PUL and DIR
<
set_>
No issue. I appreciate you trying with me here.
