Bed leveling vs height map
-
Dammit, happened again.
Printer has done the bed leveling, tells me the gantry deviation that has been reached,
right after this message the Z-Axis moves again off. You can see it by eye and you can hear it.
Then height map is again off by approx. 1mm when completed.
Which offset value is taken into affect here?
Or has it something to do with the startcode in my slicer?
G28 W ; home all without mesh bed level G90 ; use absolute coordinates M83 ; extruder relative mode G0 X60 Y-3 Z80 ; move extruder above bed, keep extruder in front for cleaning and checking M104 S160 T0; pre-heat extruder to 160C M140 S[first_layer_bed_temperature] ; set bed temp M190 S[first_layer_bed_temperature] ; wait for bed temp G29 ; mesh bed leveling using defined mesh grid G0 X0 Y-3 Z0.6 ; go outside print area M104 S[first_layer_temperature] ; set extruder temp M109 S[first_layer_temperature] ; wait for extruder temp M98 P"0:/sys/primeLine.g"; execute primeline macro G92 E0.0M572 D0 S0.07 ; set pressure advanceI only do wonder about the "W" behind the G28, as I do not have a W-Axis in my setup
Or should I use G29 S1 in the slicers Startcode? -
Can you post your full config.g and your homing files as well please?
Also please include the results of sending M98 P"config.g" and M122 in the gcode console. -
@Kubunter I always rehome Z after running or loading a bed mesh. I find this gives consistent results. You can have a file called 'mesh.g' to control the commands called when G29 is sent. Mine is:
; mesh.g ; called to perform bed mesh compensation via G29 ; M561 ; clear any bed transform G28 Z ; home Z G29 S0 ; probe the bed and enable compensation G28 Z ; home ZYes, it looks like
G28 Wis a mistake, probably should beG28 Z.Regarding your bed mesh, it looks like your bed.g isn't really working, because your X axis is not square, or bed isn't square with the Z rods. Bed.g is called by G32, so first manually square the bed to the Z axis rods (if possible, assuming your bed is manually adjustable) then use G32 to level the X axis to the bed. Subsequent bed meshes should be flat across the Y axis.
... or at least would be, except it looks like you have a Y tramming problem, ie your Y rods are not level. That's why there's what looks like a twist across the bed.

@droftarts
I will check mechanical assembly when I'm at home and Give the mesh.g a try. Sounds also good. -
Hello,
I was able to dig a little bit deeper.
Mechanically the printer is within tolerances.
Espacially the 90 degree angle between bed and Z-Rods is looking good.My problem arises when the zLift.g macro is carried out when homing.
I have commented out M98 to call the zLift macro.
Then the X-Axis stays completely leveled.What might be the problem in zLift?
Here is the code:
; ========================================================================================================= ; ; lifts the z axis in a more controlled way. If homed and possible, the z axis is lifted ; by zLiftDistance mm. Otherwise z ist liftes and current is reduced to avoid issues at ; the high end. ; ; ========================================================================================================= ; G91 ; relative positioning ; if move.axes[2].homed if {move.axes[2].machinePosition < (move.axes[2].max -20)} ; if the z position is below 20mm below max z G1 Z{global.zLiftDistance} ; lift z axis by 15mm else M913 Z40 ; reduce z motor current to 30% of set current G1 Z{global.zLiftDistance} F300 ; move z axis 15mm up slowly leveling the X gantry M913 Z100 ; return z motor current to 100% of set current ; M400 ; wait for moves to finish ; G90 ; absolute positioning ; ; ========================================================================================================= ;Thanks a lot

@Kubunter said in Bed leveling vs height map:
M913 Z40
perhaps you're reducing the motor current too much and it's skipping steps.
-
@Phaedrux Thanks a lot, that has done the trick.
Changed value to 80%, now there is no error anymore when zLift is carried out.Please mark topic as solved!
Regards Kubunter
