"out9" appears to always be enabled

brendon

I am looking to use out8 and out9 for LED strips. I have both enabled identically, but I am unable to control the level of (or turn off) out9 (it is always on, even at boot). Out8 works as expected.

I am running RRF3.4-beta5

Any help is greatly appreciated!!!

Here is the relevant config.g

; lights, right
M950 F3 C"out8"
M106 P3 S0

; lights, left
M950 F4 C"out9"
M106 P4 S0

Control of brightness:

; lights off
M106 P3 S0
M106 P4 S0

; lights on
M106 P3 S255
M106 P4 S255

Here is the entire config.g file

The issue appears to go back to at least RRF 3.2.2

dc42

@brendon do you get any error messages when you run M98 P"config.g" ?

brendon

@dc42 No error messages. Is it possible that out9 is shared with something else by default and needs to be disabled?

jay_s_uk

@brendon the laser connection uses out9 too

brendon

@jay_s_uk Thanks for checking in. I had seen this mentioned in the documents but didn't see anything mentioned about having to disable it to use out9.

dc42

@brendon you should not need to disable it, because it should not be enabled by default.

If you power up the board with no SD card inserted and no SBC connected, does OUT9 turn on?

brendon

@dc42 Yes. If you remove the SD card (I am not using an SBC), the LEDs are enabled at power on.

brendon

I have the out 4-6 jumper between V_OUTLC1 + 12v and the out 7 - 9 jumper between V_FUSED + V__OUTLC2. Moving the out 4-6 jumper to V_FUSED + V_OUTLC1 has no effect.

Moving the out 7-9 jumper between V_OUTLC2 + 12v causes out9 to always be +12v.

dc42

@brendon it could either be a hardware fault or a firmware bug. Can you try reverting to the last RRF version when you had it working? Alternatively, if you are comfortable loading firmware with Bossa, you can try erasing the firmware and seeing whether OUT9 comes on when you press the reset button.

dc42

@brendon said in "out9" appears to always be enabled:

Moving the out 7-9 jumper between V_OUTLC2 + 12v causes out9 to always be +12v.

Do you mean 12V between the two OUT9 pins, or do you mean OUT9_NEG is at +12V (so OUT9 is off)?

brendon

@dc42 Technically it has 'never worked'. I wired up the LED strips when I assembled the machine, but just got around to connecting them this week. How far back in firmware releases should I try?

brendon

@dc42 +12v between the 2 output pins.

dc42

@brendon it sounds to me like a hardware fault then. warranty@duet3d.com.

dc42

PS - if you are into hardware, you could try measuring the voltages between each end of R52 and ground. They should both be at/close to 0V for OUT9 to be off.

brendon

@dc42 Is it not worth downgrading the firmware to see if it works on any other versions?

T3P3Tony

@brendon i just replicated the same setup with a 6HC and it works fine with 3.4b5 so i think its likely that the hardware is faulty. the quickest way to check is erase it using the jumper on the board and see if it still turns on.

brendon

@t3p3tony If I erase it, will I have to use Bossa to re-write firmware?

T3P3Tony

@brendon yes you will.

brendon

@t3p3tony @dc42 Erasing and reflashing with Bossa did not resolve the issue. I will reach out to warranty@duet3d.com. I appreciate the assistance!
