BLTouch V3.0 Reassemble
-
@jaurand said in BLTouch V3.0 Reassemble:
New pin installed. At start up still blinks,
when the printer start the bltouch does a self test. if it blinks it says there is a problem. maybe the new pin is not working.
-
The set screw on the top of the body needs to be adjusted somewhat for best operation. Try giving it a turn in either direction.
-
Moved scripts around. Originally I had them under the heading ;bltouch in the config.g, bit then moved them under endstops. Also made a separate folder for the deploy and retract macros, labeled bltouch.
At startup bltouch does not perform self-test, however it was not doing that before anyways,but is no longer blinking.
Interesting to see that location of code effected this

Perhaps not the best idea of the day: M401 and M402 call these macros but won’t find them - neither in your config.g nor in the folder „bltouch“. How should they know?
Please have a short look at the documentation: here and here.
-
@infiniteloop Well I can run M401 and M402 and the pin extends and retracts....so not sure what to say but it does work

In this case, you must have left additional copies of deployprobe.g and retractprobe.g in the sys/ directory - just where they belong. Remove the folder „bltouch“ - M401 and M402 should still work.
-
@infiniteloop i misunderstood, I have a set of macros for deploy and retract labeled bltouch. looking under system editor, deployprobe.g and retractprobe.g are in the sys/ directory
-
still confused why the bltouch is not performing the self test at start up. other than that it appears to be operating correctly
-
I say mine, maybe it has been tried but you never know.
If with the machine off you pull out the pin and then turn it on, does the Bltouch work? Yes?
If yes, make the extension wiring new from scratch ... I change wires I used the Cat5 ones for network cables and above all crimp the terminals well (and with the pliers). -

The BLTouch works, just does not perform the default self test when it printer is turned on
-
Do you have the alarm release at the start of config.g?

@Phaedrux I've got it right under general preferences

M280 P7 S160 I1 ; Alarm Release and Push pin UpWhen I power it up the BLTouch will blink its read, but running Alarm Release and Push Pin Up (M280 P7 S160 I1) results in no change.
Only running Alarm Release & Touch SW Mode (M280 P7 S60 I1) stops the blinking, but then I have to run Push Pin Up (M280 P7 S90) so that it works correctly after.
-
Maybe move alarm release to the end of config. G to give it time to finish the self test.
-
@Phaedrux But the BLTouch is not even doing the self test
-
Well new problems creeping up. Pin will not retract at start of print but print starts regardless.
I'm going to try a fresh install of firmware and start that from scratch to ensure updating did not cause any issues. What is the best method for this?
-
@jaurand Upload the firmware on the system tab of DWC and it should update automatically.
-
@Phaedrux that is how i've been updating firmware before. My thought is something did not stick right causing my issues. Hence why delete it all and start from a fresh build is my thought
-
Can you post your config.g, homeall.g, and your deployprobe.g and retractprobe.g files from the /sys folder?

Remove the X0 Y0 Z1 from this command. Those parameters are no longer used.
G31 X0 Y0 Z3.467 P25
You're missing the X and Y offset between the nozzle and the BLTouch.
Neither of those should be show stoppers however.
All I can suggest at this point if you're 100% confident that your wiring is good, is to try switching to heater pin 3 of the expansion header instead of using heater pin 7.
You'll need to change the heater unbinding to reflect H3 instead of H7
M307 H7 A-1 C-1 D-1 ; Disable the 7th Heater to free up PWM channel 5
And check config-override.g to remove any entry for H3.
As well as change the servo commands to target P3 instead of P7.
