Hello, ich recently upgraded from RRF2 to RRF 3.2.2RC2,
I took my time to exchange all the commands and everything seem to be working well, almost.
I have setup my z-probe to BLtouch via
M558 P9 C"zprobe.in" F100 H11 R0.4 T250 A30 B1
M950 S0 C"exp.heater7"
G31 X2 Y57 Z1.95
which works well, I guess
To calibrate z (with my leadscrew adjustment) I have been using the M558 (old command)
M558 P9 F750 H10 R0.3 T4000 A1 B1 ; Set single probing at faster feed rate
to change the feed rate (to be faster is Z ist off a lot) and then change it back after initial first probing to get more accurate result.
I have migrated the command accordingly to
M558 P9 C"zprobe.in" F750 H10 R0.3 T4000 A1 B1 ; Set single probing at faster feed rate
(F750 instead of F100 mainly)
but I have noticed that whenever I do M558 to change feed rate, my G31 settings with offset etc are reset fully.
Is there a new preferred way to just change feed rate for bltouch which doesn't reset G31, or do i have to set G31 again always after each M558? How can i avoid resetting that G31 ?
I just tested the M558 F750:100 but that is pretty useless.
; called to home the Z axis
G91 ; relative positioning
M280 P0 S160 ; Alarm Release and Push-Pin UP
G1 H2 Z5 F6000 ; lift Z relative to current position
G90 ; absolute positioning
G1 X162.3 Y115.7 F6000 ; Go to first bed probe point and home Z
;M558 P9 C"zprobe.in" F750:100 H10 R0.3 T4000 A1 B1 ; Set single probing at faster feed rate
G30 ; Do a single probe to home our Z axis
;M558 P9 C"zprobe.in" F100 H5 R0.3 T4000 A15 B1 ; Set multi probing at slower feed rate
G30 P0 X10 Y115.7 Z-99999 ; probe near a leadscrew, half way along Y axis
G30 P1 X320 Y115.7 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors
G1 X162.3 Y105.7 F6000 ; go to first bed probe point and home Z
G30 ; Probe again to get a more accurate position
G1 H1 X0 ; home X axis
G1 H1 Y0 ; home Y axis
The F750:100 i kind of messed up
It will cause the G30 probing to be at 750 when going down and 100 when going up for second probe, then down with 750 again for second probing then stay at 100 for the travel for leadscrew adjustment.
I guess its resetting between 750 and 100 the wrong way
