config.g getting there

Phaedrux

M566 X1500 Y1500 Z1000 E200 ; set maximum instantaneous speed changes (mm/min)
M203 X2000 Y2000 Z375 E800 ; set maximum speeds (mm/min)
M201 X4000 Y4000 Z150 E800 ; set accelerations (mm/s^2)
M906 X900 Y900 Z900 E900 I30 ; set motor currents (mA) and motor idle factor in per cent

The Z jerk value is a bit high perhaps. And the max speed and acceleration a bit low.

Try M556 Z300, M203 Z600, M201 Z300

For motor currents target 70% to 85% of the rated max for the motor.

M307 H7 A-1 C-1 D-1 ;disable heater 7 to free up for servo signal for BLTouch
M307 H3 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch

You still have two heater pins unbound. If you're using Pin 3 for the BLtouch remove the H7, or vice versa.

M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1
M305 P1 X200

You still have two different things configured for heater P1. A thermistor and PT100. Which are you using?

PT100
ok this is a confusing part im using pin 8 heater3 from here https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe and i'm using a PT100

Phaedrux

In that case, delete M307 H7 A-1 C-1 D-1 ;disable heater 7 to free up for servo signal for BLTouch and M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1

config.g did i mention I'm 41 and shit a retaining most information. thank you very much for you're patience

jobesynoob1234

just so you know what your dealing with this is a iture of my "temp" setup my Frankenstein mad up of abs

jobesynoob1234

and also thats the way my bltouch stays after it hits home

But does it deploy, retract, and trigger as expected?

jobesynoob1234

yes all macros work so i take it the red flashing light is normal:/ because when i move the z-axis up and home z again the probe stays retracted and moves up instead.

Not sure what this means exactly.

Is the BLTouch flashing red or just lit at all times?

jobesynoob1234

@Phaedrux flashing

Phaedrux

Flashing would indicate error state. At what point does it error?

jobesynoob1234

@Phaedrux as soon as it probes the bed

Phaedrux

But it stops movement as it should?

jobesynoob1234

@Phaedrux i just tried to upload a video but files to big and yup it stops but I can't use home z again until I click on the alarm release and drop pin macro because it will just keep moving up on every press

Phaedrux

@jobesynoob1234 said in bltouch v3.1 help:

alarm release and drop pin macro

You can add that command to the start of your homing files to make sure the probe is ready before homing.

Still doesn't explain why it's erroring. But if it works otherwise I'm not sure what else to say.

jobesynoob1234

@Phaedrux yup thats why its driving me nuts 🤯and being a noob don't help

jobesynoob1234

tomorrow i will solder all bltouch wires to eliminate connectors and see if that helps. Thank you so much for helping me on this thing hopefully I will win

jobesynoob1234

well that was a waste of time soldered wires made no difference!
i also forgot about the error message after i used the G30 S-1 that says the (Z probe already triggered at start of probing move) its very confusing how all macros work and the only macro that seams to work different is the self test because they say it keeps going until you give it another command. But for me it stops its self after a bit $:\$

post a picture of all your wiring
