ENDSTOP_Z_BACK_ON_HOME

gorf25

I am trying to set my corner to plate height but having some problems, ENDSTOP_Z_BACK_ON_HOME I have been changing the values for the x y and zbut I am guessing I am doing something wrong if I change the value in ENDSTOP_X_BACK_ON_HOME it doesn't seem to make any difference, from what I have found I have to change all three the x y and z for it to back off the endstopbut I can't set the backoff correct for each endstop, is this the correct way or is there a different setting I should be using.
thanks gary

If you have a delta is is wrong. Then only Z has an effect but on all 3 towers. Firmware eeprom has a extra offset for each endstop that you set with M131/M99/M132 as described in our z probe documentation on homepage.

thanks so there is no software setting for the offsets, only eeprom. yes its a delta.ok I had eepron turned off trying to get the corners and center calibrated before Isent the settings to eeprom but will change my approach to the problem, this is myfirst try with repetier like it so far but so many setting I don't understand..Thanks gary

forgot does probing need to be on? and I don't have a probe installed on printer.
thanks gary

No, setting endstop offsets is independent of z-probe.

I read the z-probe file on main websiteI turned on eeprom now, but if I send a g321 I get no movement do I need to enable probing also?.thanks gary

From description

G131 - set extruder offset position to 0 - needed for calibration with G132

so if extruder has offset 0,0 no move will take place and you could even omit this. It is only for dual extruders where the extruders are not in the effector center.

not sure where 131 came from I used g321 as explained in the video from the probing doc's on web siteit said to turn off 1 motor at a time and put a rod to the frame and move down the axis to the rod and do each onethen sent a g321... but with the g321 I got no movement to home that's what I am trying to figure out I don't have probing turned on do I need to?.
Thanks gary

There is a M321 in docs, but to move for 10 seconds send M99 X0 or Y0 or Z0 depending on which motor to turn off.

gorf25

Guess I am miss understanding the video it looked like to me after you moved the axis down to the rod and had all 3 at the proper spacing with the rod then a m321 was sent it looked to me like the 3 axis homed and you where setting the proper xyz heights. offset heightthanks gary

If you read the doc it says to position with M99 and if positions are ok send

G132 S1

whcih is the homing like move to set offsets you mentioned.
