i can tell you how i did it i wanted to write a short guide but im currently under a bit of stress so ill just post a quick walkthrough

you have to wire a Z probe of your choice i took a mechanical endstop switch and wired it to the z-min endstops of the rambo soldering the a cable to jumper pins and pluggging them in correctly.
you then have to choose a mount for your zprobe i got an e3d and found this wonderful mount on this board it works wonders try to use a mount wich has no x and y offsets since i couldnt get it to work with offsets http://forum.seemecnc.com/viewtopic.php ... obe#p77845

afterwards you have to specify in the eeprom where you located your Z-Probe(if its z-min like mine you can use this

Code: Select all

Code: Select all
#define FEATURE_Z_PROBE true
#define Z_PROBE_PIN 10(this is where it is plugged in)
#define Z_PROBE_PULLUP true
#define Z_PROBE_ON_HIGH true(this is for the logic when you want the probe to trigger most probes have NC (normally closed) and NO(Normally Open) contacs .so if you have messed up the wiring you can change the logic to the one you need here)
#define Z_PROBE_X_OFFSET 0
#define Z_PROBE_Y_OFFSET 0
#define Z_PROBE_WAIT_BEFORE_TEST false
#define Z_PROBE_SPEED 2
#define Z_PROBE_XY_SPEED 150
#define Z_PROBE_HEIGHT 39.91(this is the height difference between the nozzle and the switch activation point measure it using the paper grip method on the nozzle then mount the probe and bring it down till it triggers use 2-3 trys to get the most accurate trigger point possible)
#define Z_PROBE_START_SCRIPT ""
#define Z_PROBE_FINISHED_SCRIPT ""

when you have reflashed your eeprom you need to test your zprobe with the g32 command when you have z probe on high true it should read low when not pressed and high when pressed
if you got everything wrap it under your hotend open the opendact tool and go to advanced and change the fsr to the z probe specify the z height and give opendact some room to brief for the first few calibrations with probe height 20 or so i like to probe very slow with a mechanical switch so it doesnt change the probing point so much(something like 3-5mms is okay)

if you got questions i can help you i ccan post pictures of my setup too if you want . i have calibrated once with this and i havent had the need to recalibrate since then but if MY ZPROBE IS READY

Haven't tried again yet, I've got a deadline that I'm printing for and haven't taken it out of commission to try again yet.
Also half way hoping that this thread pans out and finds my smoking gun before I do

as if you knew that they will arrive today:)))
ill probably gonna put them on the rostock this weekend but its so hard to find the bed screws here in europe:O ill probably gonna end up flexxing them shorter..
