BLTouch + Expansion Breakout Board
-
Hi there ,
Back to BL Touch, please help...
I believe I tried every tutorial, forum post and variation (maybe that's the problem... I probabbly did a mess)And here is how my Bl Touch is behaving on each setup:
SETUP 1 (connected to the expansion pins on Duet wifi using heater 3)
1 - It does the self test
2 - Stays with the probe retracted and the red light on
3 - I can command it with M401 to lower the pin
4 - If I do a M402 or a G30 to start a probing pass it goes looping on deplying and retracting thr pin with the red light on.SETUP 2 (connected to the expansion breakout board on heater 7)
1 - It does the self test
2 - Stays with the probe deployed and the very low blue light on
3 - I can command it with M280 P7 S90 to retract the pin (red light turns on)
4 - I can command it with M280 P7 S10 to deploy the pin
5 - If I do a M402 or a G30 to start a probing pass it goes looping on deplying and retracting thr pin with the red light on.I already tried other unit , same results.
PS: a part from coding mess up, the only phisical thing that happened was that the 1st time (and some others) I connected the bl touch to star testing I did not used the resistor to low from 5v to 3.3v... hope that didn't dammaged the Duet.
thanks

Does your deployprobe.g file contain :
M280 P7 S10? -
@scachi yes it does... Is that correct?
Thanks -

ThanksYes, thats correct.
The looping of pin deploy/retract sound just like the test mode,so I was wondering if there is this command somewhere put in a config file by accident.
This shouldn't be in any file: M280 P7 S120
When you issue this selftest command, does it excatly do the same pin-in/out cycle with the same timing as you are observing ?
As M402 is for retracting, check your retract command file retractprobe.g, it should contain: M280 P7 S90 -

Which firmware version are you using?

Please post the contents of your config.g, deployprobe.g and retractprobe.g files. Also bed.g if you are doing G32 bed probing

Hello there,
I'm using 1.21 (2018-03-21)I noticed that posting the firmware here with the comments inside it creates a mess... if you prefer I can clean all the comments so it will be easier to read. let me know, please an thanks!

RETRACTPROBE.G
M280 P7 S120 I1This is the test mode you are seeing, it is wrong.
retractprobe.g has to be: M280 P7 S90 I1 -
Ok... I noticed that my retract probe had s120 instead of s90...
-
@scachi Yes.. i just noticed that...
thanks I lot, it was your post "this shouldn't be in any file" that made me realize that... now I must try a probe process to see if it works, I will let you now in a few minutes -
Yes! it did the probing...I used the G32 to test... Now I need to get familiar with G32, G30 know the differencies between them and the G29 ...and ofcourse calbrate it well.
thanks!!!
