Hi - it might be more of a Userquestion than an issue - i use the plugin and it mostly works fine. But somehow (my pei sheet tells a few stories already) the offset changes so much, that it scars the sheet.
I do very simple startscripts:
`[gcode_macro G32]
gcode:
G28
G0 Y330 F3000
CLEAN_NOZZLE
G28
QUAD_GANTRY_LEVEL
CLEAN_NOZZLE
CALIBRATE_Z

[gcode_macro PRINT_START]
Use PRINT_START for the slicer starting script - please customise for your slicer of choice
gcode:
G32 ; home all axes
BED_MESH_CALIBRATE
G1 Z20 F3000 ; move nozzle away from bed`
Home, clean nozzle, home again, qgl (its a voron 2.4), clean nozzle again, calibrate Z.
Its fine - my values are consistent, no big spreads (single jumps but median is fine)
probe at 175.000,155.250 is z=7.608202 probe at 175.000,155.250 is z=7.610702 probe at 175.000,155.250 is z=7.610702 Switch body >> probe at 228.000,333.000 is z=8.104452 probe at 228.000,333.000 is z=8.104452 probe at 228.000,333.000 is z=8.104452 probe at 228.000,333.000 is z=8.104452 probe at 228.000,333.000 is z=8.105702 probe at 228.000,333.000 is z=8.105702 Nozzle >> probe at 231.000,350.000 is z=0.003202 probe at 231.000,350.000 is z=0.001952 probe at 231.000,350.000 is z=0.000702 probe at 231.000,350.000 is z=0.000702 probe at 231.000,350.000 is z=-0.000548 probe at 231.000,350.000 is z=-0.000548
But my overall offset changes from .55 to .8 from print to print, beeing to close from time to time.
Now i changed the nozzle and the measurement (i posted above) gave me an offset like OFFSET=-0.823048 what was .35 to big. i needed to adjust it to around .5 to start printing and stopping killing my pei sheet.
the plugin should calculate the offset even after changes of builplate or nozzle right? is there anything i can do to get consistent offsets? I adjusted my switch offset so it did a good job on the first sanity test and then said "fine, thats it" and hoped from now on it should do the trick. my sheet tells another story.
magnets are glued into place, no movement here so the klicky should be fine. should i do more probes?
thx!
