3D touch Prbing failed

Post by janie » Tue Jan 01, 2019 9:32 am

G'day from down under (in the dumps)

When the printer starts it seems like it is testing ok, then this below when I do the aut bed leveling.

Also the Z only move up, then the probe puches down and up, waits and the raises again.....

Code: Select all

12:22:20.024 : Error:STOP called because of BLTouch error - restart with M999
12:22:20.024 : Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)
12:22:26.148 : Error:STOP called because of BLTouch error - restart with M999
12:22:28.842 : X:162.00 Y:125.00 Z:10.50 E:0.00 Count X:13009 Y:10100 Z:4200
12:22:39.703 : Error:STOP called because of BLTouch error - restart with M999

12:22:40.622 : X:152.00 Y:20.00 Z:25.43 E:0.00 Count X:12206 Y:1616 Z:10172
when I do M999 I get this:

Code: Select all

12:22:40.622 : X:152.00 Y:20.00 Z:25.43 E:0.00 Count X:12206 Y:1616 Z:10172

12:31:17.306 : Resend: 3
12:31:17.322 : Error:Line Number is not Last Line Number+1, Last Line: 2
12:31:17.322 : Resend: 3

Slight upward movement BEFORE extending the probe is understandable, because if you started out with the nozzle clear down at ZERO there would not be enough room to extend the probe tip as it has to in order to measure for the bed. But after that slight lift, the tip should extend (and the light should go out) and then a downward movement to do your Home Z function (3rd axis of the Autohome G28 command). When it finds the bed once, it should stop, raise back up a little, extend the tip again, and move back down for a second feel for the bed (at a slower rate of decent). This 2-stage probe is the default in Marlin - but you don't say what firmware or what printer you're dealing with.

Teaching Tech on YooToob speaks your particular permutation of English, and does several vids on applying the BL Touch to an Ender 3 (my own weapon of choice) including firmware mods with both the original Marlin code and from the TH3D "unified" starting point. My suspicion is that what you need to be checking is addressed at about 8:50 in this one:

Somewhere in those Z inverting booleans you need to flip something.

Good luck with that, Ozlandian
