Auto Calibration of Nozzle Z offset

@nicolas-brejat said in Auto Calibration of Nozzle Z offset:
I tested configuring two probes as you have done but it was under firmware 3.3.0
Perhaps something is different under your firmware.
Did you try including the parameter K0 for the first M558/G31 commands?

@fcwilt do you mean it's workable under firmware 3.3.0? I'm using RRF 3.0 now, if change K1 to K0 in M558/G31 command, the "K too high" error will disappear, but K0 is for leveling probe, so it'll have below error when auto home:

; Z-Probe
M558 P5 C"probe" H5 F120 T6000 ; set Z probe type to switch and the dive height + speeds
G31 P500 X0 Y0 Z3 ; set Z probe trigger value, offset and trigger height
M557 X15:215 Y15:195 S20 ; define mesh grid
M558 K1 P8 C"PC5" T18000 F180 H2.4 A10 S0.0025 R0
G31 K1 P500 X0 Y0 Z-0.5he meant add K0 to the first M558.
can you post the output of M115? we never released a version of RRF3.0 for the Fly-E3 -
@jay_s_uk it was RRF 3.0 before, just now updated to 3.3, but still same issue.
-
@nicolas-brejat ok, thats still not the latest release.
Please find the latest release here https://github.com/gloomyandy/RepRapFirmware/releases/tag/v3.3_2 -
@jay_s_uk after update below firmware, the LCD 12864 screen becomes blank, Wifi fail to connect. does it need to change other settings after update 3.3.2 firmware?
-
@Nicolas-Brejat No. You've loaded the incorrect file. You should be using the ESP8266wifi file and not the SBC file.
-
@jay_s_uk ok, still same error. so it's not related to firmware version?
-
@nicolas-brejat one for @gloomyandy
-
@jay_s_uk We only currently support a single probe.
-
@gloomyandy do you mean RRF firmware doesn't support 2nd probe? if change to duet board, will it work?
-
@nicolas-brejat the STM port currently doesn't support more than one z probe (mainly as a hang over from all the restrictions initially made to the LPC port) but the duet boards do.
It has been added to the to-do list to investigate increasing that limit as part of the next release. -
@jay_s_uk ok, that make sense. hope next release will fix that. thanks
