Placement of Gcodes
-
Thank you will try that much appreciated
-
Is the BLTOUCH PREP code worth having in place ?
-
It's not a bad idea to leave it in place just to ensure the pin is retracted and any errors cleared at startup.
-
Ok thank you again
-
Have swapped out the sections with the code you kindly added other than changing the H5 to H15 I am still getting erratic behaviour from the sensor.
I bought an original smart V3 off Antclabs on Amazon so I don't question its integrity.
I have checked the wiring and this is without fault.
After the print bed lowers the hot end homes to y then homes to x the hot end moves to the centre of the print bed and just as the bed starts to rise something changes it to lower the bed 15mm again and the BLTouch goes into flashing red.
If I turn the machine off and manually deploy the pin and then start the machine and home it I stand a better chance of it working but not consistent!
Just a note on powering up the printer it does. not do a self test and codes from the console have no effect either.
Should I replace or is it human error again on my part lol
Thanks

Can you post your homing files?
-
What happens when you try the static test described here?

Hi
Homing sequence is y first then x then z is homed at the centre of print bed,
Thank you

Hi,
Have tried the M401 command from the touchscreen with the probe illuminated in red the sending of the M401 command then makes the sensor flash red with no deployment of the sensors pin.
-
So last ditch attempt have taken the pin out cleaned it put it back and it did its self test several times hooray oh hang on that was short lived.
I am now looking for an alternative to the bl touch thank you for all your help getting me to this point but I must just have the crap one! lol
I don't want to be ploughing the printhead into the bed so its time to move onto something more reliable IR ?
