BLtouch does not work after changing to DUEX5 board

Haggan90

The strange thing is that the red LED lights up all the time, and none of the self test/other commands work. Only thing I did was change from Duex2 to a Duex5.

Javajoeuk

my bl touch v3.1 was staying red on startup when it could not complete its self test. I thought it was the wiring after moving it upto the printer and extending the cables but they tested ok and after reading someone elses post they mentioned the grub screw which I had not touched. So I gave it a little adjustment turned the printer back on and it completed it self test straight away as normal. Give it a go it might work.

Haggan90

@Javajoeuk Ok! I will test that!
You mean the little screw on the top of the BLTouch right?

Javajoeuk

yes be gentle.

Haggan90

@Javajoeuk Tried it with no success, it won't activate for some reason..
Any other idea?

Javajoeuk

no sorry

Haggan90

@Phaedrux Do you find anything strange in the config?

Veti

can you try a different pwm port?

Haggan90

@Veti Yes of course, which heater do I need to disable if I wan to use PWM_2?

Veti

try 5 or 7. they are often used for bltouch

Try disabling heater 7 and use PWM5 on the DueX, that's a common combination.

Haggan90

@dc42 Thank you, I will try that!

Do I need to change anything more then this: M307 H7 A-1 C-1 D-1 ?
And remove the M307 from config-override.g

Phaedrux

You'll also have to update your deploy and retract macros to reference the new pin number as well.

Haggan90

@Phaedrux Should that be M280 P5 S10 then?

Phaedrux

P7 for heater pin 7

By the way using pins gets a lot easier in RRF3. Might be time to consider updating.

Haggan90

@Phaedrux Right now I just want the printer to work again, been down for almost a year now

Changing to heater 7 did not work, still the same problem..

Phaedrux

Please post the current version of your config.g, config-override.g, deploy and retract macros, and please double check which pin you're connected to. And refresh me on which wires are going where.

Haggan90

@Phaedrux Ok!

Does the BLTouch do a self test at power on?
Does sending M401 and M402 deploy and retract the pin?
