How do I speed up the bed mesh level

alankilian

@rexx One way would be to probe fewer points.

Another way if to not lift the probe as far off the bed when moving to the next point.

There are a few things that come into play, most controlled by the parameters in M558.

The travel speed between probe points can be increased. The probing dive speed can be increased to a point (you don't want to probe too fast which can lead to inconsistency). And the dive height can possibly be reduced to a minimum so you don't have as far to go to touch the bed.

@phaedrux so is this speed change for travel in the config.g or….

@phaedrux
; Z-Probe
M950 S0 C"exp.heater3"
M558 P9 C"^zprobe.in" H5 F120 T6000
G31 P500 X-42 Y-1 Z2.90
M557 X15:315 Y15:315 S75

so is the speed the f120 in the M558 line?
is the T6000 the dive height?

rexx

@phaedrux ok so
H5 is the dive height
F120 is the travel speed
T6000?

@rexx You can look up all the parameters for ALL gcode HERE.

Tnnn Travel speed to and between probe points (mm/min). This is also the Z lift speed after probing. The corresponding axis speed limits set by M203 will be used instead if they are lower.

@alankilian thank you

rexx

@alankilian i have the travel speed increased much better now thank you

can i change the probe points or how do i do this
