Bed level speed?

Chriss

Hi *,

I have a question regarding the ravel speed at "G30 P?". The head moves very slow between the points I address with "G30", is there a way to speed that up?

Speed settings:

M566 X900 Y900 Z20 E3600        ; Set maximum instantaneous speed changes (mm/min)
M203 X18000 Y18000 Z3000 E5000  ; Set maximum speeds (mm/min)
M201 X2000 Y2000 Z100 E800      ; Set maximum accelerations (mm/s^2) 
M204 P500 T2000                 ; Set printing acceleration and travel accelerations

bed.g

M564 S0 ; Disable protection



while iterations <=1            ; Perform 2 passes.
	G30 P0 X50 Y0 Z-9999		; probe left leadscrew
	G30 P1 X400 Y0 Z-9999		; probe right leadscrew
	G30 P2 X200 Y330 Z-9999 S3 ; probe leadscrew at the end
	G1 H2 Z8 F2600              ; raise head 4mm to ensure it is above the Z probe trigger height
	M400                        ; finish move, clear buffer

while move.calibration.initial.deviation >= 0.003 ; Perform additional leveling if previous deviation was over 0.01mm.
    G30 P0 X50 Y0 Z-9999		; probe left leadscrew
	G30 P1 X400 Y0 Z-9999		; probe right leadscrew
	G30 P2 X200 Y330 Z-9999 S3	; probe leadscrew at the end
    G1 H2 Z8 F2600              ; raise head 4mm to ensure it is above the Z probe trigger height
    M400                        ; finish move, clear buffer

echo "Gantry deviation of " ^ move.calibration.initial.deviation ^ "mm obtained."
M564 S1 ; Enable protection

G1 X200 Y200    ; Back to the middle

Cheers, Chriss

@chriss the travel speed is determined by the T value in M558

Thanks..... what a shame...

M558 P9 C"121.io0.in" H5 F120 T6000		; set Z probe type to bltouch and the dive height + speeds

@chriss you can always add a G1 move between each of the points at a faster rate. Maybe only part way, so the last 10mm are at a slower speed incase your probe needs any recovery time?

Chriss

@engikeneer I tried that, to be honest, but the G1 was not really faster surprisingly. Anyway, that did it for me. I have other open flanks with that build.

@chriss said in Bed level speed?:

Thanks..... what a shame...

Why is it a shame? Why don't you increase the M558 T parameter to 18000?

Chriss

@dc42 The shame was for my comment of "M558", I noted already "speeds" and did not see it so I asked here.

Cheers, Chriss
