ABL command ignored

[adamfilip]

I notice that sometimes, my start up code for ABL gets ignored, printer starts out with homing and then starts printing.
Not sure why.. i end up manually sending down a ABL code and it begins.. and then i send down my print job after

using startup code in Simplify3D

[beerdart]

My S3D start code.

G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28
G29
G1 Z15.0 F{travel_speed} ;move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F200 E3 ;extrude 3mm of feed stock
G92 E0 ;zero the extruded length again
G1 F{travel_speed}
;Put printing message on LCD screen
M117 Printing...

I just came to comment out that am having the same problem is being ignore. It works if i send a manual g29 also.

my Start Code was simply

G28
G29 E

My Slic3r start gcode:

M117 Resetting Printer...
G28 ; home all axes
M117 Heating Print Bed...
M190 S[first_layer_bed_temperature] ; set bed temperature, wait for it to reach target before proceeding
M117 Homing...
G28
M104 S[first_layer_temperature] ; set hotend temperature. Use M109 to set and wait
M117 Auto Bed Leveling...
G29 n 4 ; auto level
G1 X99 Y99 Z1 F1500; reposition extruder
M117 Printing...
M117 Printing...

I copied beerdart gcodes and it worked like it did. But then it just decides when ever it wants to stop. Here a video showing what is does. It just does a G28 and forgets about G29. Also when the power kicks in the power supply the servo twitches i wasn't getting that before.

Uploading another video were autobed leveling is working. It works when ever it wants to work. Marlin 1.0.2

Servo did not twitched Since the first video and the second video. But sometime i did notice when it does the autobed leveling it retract way more than what i have in the configuration file and makes my LCD flicker.
Other video Autobed leveling working. moments after finishing the last video recording. And not changing anything in setting. Or changing anything at all.

Sounds like your servo is drawing too much power when it tries to retract too far, causing RAMPS to brown out. Make sure your angles are set properly so the servo doesn't have to strain.
