Live Z adjustment intermittent #20705

Closed soaringpaul closed 3 years ago

soaringpaul commented 3 years ago

This is probably not a bug, but an error on my part. I have two printers, an Ender 2 and a Geeetech I3, both with Marlin 1.1.9 and both showing the same issue, which is that live Z adjustment for the first layer sometimes works, and sometimes does not, the display always shows the adjustment but the Z axis does not travel. I can load the same GCode and live Z will work and next time not. It seems to be random. I get the same result with Live Z or Babystepping. Can anyone suggest what I might have wrong? My Start Gcode:

M300 S300 P1000 ; beep for 1 second M0 Insert Z Switch M420 S1 ;turn levelling on? M420 Z10 ; bed levelling faded by layer 10 G28 ;Home

M140 S50 ; set bed probe temp M104 S160 ; set extruder probe temp M109 S160 ; wait for extruder probe temp M190 S50 ; wait for bed probe temp

G29 ;Autolevel G1 Z10.0 F3000 ;Move Z Axis up M104 S{material_print_temperature} ;Start heating extruder M140 S{material_bed_temperature} ;Start heating bed M109 S{material_print_temperature} ;Wait for extruder to reach temp before proceeding M190 S{material_bed_temperature} ;Wait for bed to reach temp before proceeding M300 S300 P1000 ; beep for 1 second M0 Remove Z Switch G92 E0 ;Reset Extruder

Marlin 1.1.x is no longer being worked on.
