Aus 3D IR probe set up problems
-
I am setting up a new AM8 (Modified Anet A8) with a Duet Wifi board and having fun and games trying to set up a suitable Z Probe. I started with a BL Touch that was working OK and then failed. After that I figured I would try an Aus3D IR probe (a clone of DC's IR probe.
I would like to use the probe for automatic bed leveling and to home the Z axis.
For initial set up I used a micro switch for homing the Z axis
I have followed Dave's blog on setting up his IR probe but am having problems trying to switch
from the z end stop to using the Z probe for homing.
The relevant section of Config.G is here:; End stops
M574 Y2 S1 ; Set active high end stops; Z-Probe
M558 P1 ; Enable Z probe
G31 P500 Z1.63 ;Trigger ThresholdAnd Homez is here:
; homez.g
; called to home the Z axis

G91 ; relative positioning
G1 Z5 F6000 S2 ; lift Z relative to current position
G1 S1 Z-245 F1800 ; move Z down until the endstop is triggered
G92 Z0 ; set Z position to axis minimum (you may want to adjust this); Uncomment the following lines to lift Z after probing
;G91 ; relative positioning
;G1 S2 Z5 F100 ; lift Z relative to current position
;G90 ; absolute positioningI suspect my problem is in the Home Z file. I also need to confirm that with the IR probe connected the Z microswitch should be disconnected.

Having had a good read of the RepRap Dozuki, I believe I have answered all of my questions and amended the Bed.G file to make things work.
The probe is now working correctly and the machine is now working on its first test print.
