Custom Home Routine with G28

OiD

Hi all!

I'm currently converting an industrial 3D printer to repetier and I need some custom homing routine to avoid collisions.

In short;
a)I need the X axis to home and then move away 30mm for example then continue homing Y and Z.
-So far i can do this with "Endstop distance after homing" but this sets the position as 0 and I cannot go to -30mm for example.

b)I need to move the Y axis past the Y endstop to perform an action but as soon as the optical endstop is activated I cannot go furhter.
-All axes have start and end sensors, I guess I could use those some how.

Thanks for any input!

Ok, I was trying to edit inside of the Printer.cpp file for the Home function.

Just found out how include actual G-code with "GCode::executeFString(PSTR("G1 Z30"));" so I've replaced G28 with my own G-code that calls all the movements and copied the original G28 to G2828.

With this I can home however I want and avoid all obstacles. :)

Still can't figure out how to move an axis in the negative direction past an endstop. :(
Is there a way to disable the endstops, move into the negative directions (or setting an offset on the axis and going to zero)?

Thanks!

You can only move past endstop if ALWAXS_CHECK_NDSTOPS is 0. Target position test might also prevent this, so use G1 S1 to disable target position check.

Thanks! That solved it. Will have to toggle G1 S1 to perform the routine.

Is there a way to send a command from the Repetier FW to Repetier-Host to update the Coordinates? Similar to M114 to the LCD but acting like @isathome ?

Now I can get on with the servo loop for the extruder, thermocouples, the 120V heaters and squirt some plastic!
