BL Touch

fcwilt

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?

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

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

still blinking red

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

Self test is when you first switch on the machine / give it power , the pin will deploy than retract and go solid red.

@peter247 It hasn't done that yet so far even after multiple reboots.

peter247

if it doesn't do that it is a bltouch fault and not a configuration fault.
pull the pin and see if it is bent

Gost101

I legit unplugged the bl touch wires and plugged them back in. It did the move thing and actually homed z. lol

peter247

if you get the red flash the deploy and retract doesn't work until you reset it.
reset it by power recycle OR S160 , eg M280 P3 S160

Gost101

Granted it didnt stop and kept going but progress

Gost101

The Z axis wont stop moving down even after the plunger is pushed in.

peter247

can you deploy and retract the probe ?

Gost101

@peter247 I can deploy and retract the probe

the wires that come with the bltouch are notoriously bad.
