BL Touch

[Gost101]

I have a Duet WIFI on a CR-10 S5 with a BL Touch that I havent been able to set up. Anyone have a file already created?

[Phaedrux]

Why not sure create a config file set from the config tool for your board type and firmware version and compare to what you have now. It's going to depend on your firmware version and how you have it hooked up, which you haven't mentioned.

I completely replaced my gcode just in case i was doing something weird. Im rocking Firmware 2.03 (2019-06-13b2). The BL touch is mounted to the side of the Bondtech DDS system here is a picture for reference from the site:
I get the following error when z is independently homed and when homing all.

 G28 Z
 
Error: M280: Invalid servo index 7 in M280 command
 
Error: M280: Invalid servo index 7 in M280 command

Hi,

So did you try other values in the M280 commands to determine what is the correct value?

Frederick

[Gost101]

@fcwilt Lol, i dont even know what the M280 command is.

[Gost101]

I fixed the first error however now im getting this:

G28 Z
 
Error: Z probe already triggered at start of probing move
Error: Homing failed

Well you should have system files deployprobe.g and retractprobe.g

deployprobe.g should have something like
M280 P0 S10 ; servo setting to drop pin on BLTouch v3.0

retractprobe.g should have something like
M280 P0 S00 ; servo setting to retract pin on BLTouch v3.0

The P parameter needs to be changed to match your setup.

---

Also do you have a G31 command somewhere else besides config.g?

The one there is strange. The P parameter should be 25 for the BL Touch.

The X and Y are likely not 0 - that would indicate the pin of the probe is exactly where the tip of the nozzle is.

The Z is likely not zero - that would indicate that when the probe triggers the Z position is Z=0.

My G31 looks like
G31 P24 X0 Y24.5 Z2.80

Yours needs to be updated to match your setup.

Hi.

You cannot use my values - they are specific to my hardware.

You have to determine values that are correct for your hardware.

The X parameter has to be the distance from the tip of your nozzle to the pin of the BL Touch along the X axis.

The Y parameter has to be the distance from the tip of your nozzle to the pin of the BL Touch along the Y axis.

The Z parameter has to be the Z position when the BL Touch triggers.

@fcwilt I roughly measured the X distance with calipers. the Y axis controls the bed going forward and backwards. How can I determine the Z value?

@Gost101

Have you tried moving to a different heater pin ?.
I could not get heater 3 working , so moved to heater 7.

[Gost101]

Ill move to heater 7, standby for code changes and status

[Gost101]

@peter247 I moved to heater 7, no change

[peter247]

@Gost101

Are you getting power and self test when you first give it power ?

[Gost101]

The pin does not drop or retract the bl touch is still blinking red while status code:

G28 Z
 
Error: Z probe already triggered at start of probing move
Error: Homing failed

@peter247 Power and self test?

[peter247]

@Gost101 said in BL Touch:

still blinking red

That is a important bit to tell !!!!!
