BlTouch… Quasi works
-
Hi…
I am triying to do work BlTouch.... and afted hundred of test, i have discovery somethigs:
First, what the diference beteewn
Deploy BlTouch: M280 P0 S10 (This is the gcode, in Antlabs web) and M280 P3 S10 I1 (This is the gcode in this forum)
Retract BLTouch: M280 P0 S90 (This is the gcode, in Antlabs web) and M280 P3 S90 I1 (This is the gcode in this forum)M280 - This send the gcode to servo.
P0 - The number of the servo... When is P0 and when is P3???
S0/S90 - Angle/Microsegonds, suppose, the duration of the pulse in the order to deploy o retract...
I1 - I dont know....i haven't see this flag in wiki...I think i am in the way, now i dont have, but near miss... one word SOLENOID.
BlTouch have in upper and screew to adjust the "force" of solenoid....
Well after test i have discover:
- When, in start screen, Sensors/Z Probe is Greyed, BlTouch is in error mode, and no signal sends.
- The BlTouch, respond at the commands of Deploy, Retract and Test.
- When BlTouch was working in Smoothieware Board... Works correct. The issues has come when i have changed Smoothieware to DUET3D WIFI board.
- The blue led is on, depend the position of top screw, i have read that is the force of solenoid activates. In this moment i am doing test with this, tightening and loosening the screw, i am following this metod (please check)
A- Turn off printer
B- I loosen the screw until exit above the Bltouch about 1 mm
C- Turn on printer
D- See if blue led is on, if this is the case E, and is of I
E- Power off the printer
F- I tighten the screw 1/4 turn
G- POwer on the printer
H- Go to D
I- Send by console, this commands M280 P3 S10 I1 (deploy) M280 P3 S90 I1 (retract)
J- In this moment i am here... the problem in this moment, when i send the command to retract, BlTouch enter in error mode (Start to blink) and i have to send a reset
gcode... and when i do this, BlTouch, belive, dont send to duet his actual position...
I have measure tension, when is retracted or deployed (i dont remember) and can read with multimeter 3,1.... a little low? No. Or is suficient for Duet understand that it is activated?
There is some sytem for this tension will be more near 3,3V? -

I1 - I dont know....i haven't see this flag in wiki...P3 says which output pin you are using (heater 3 on the expansion connector). I1 means invert the signal, because the heater signals on the expansion connector are inverted.

P3 correspond to Heater 3 (pin 8).? Orange wire?
