Homedelta.g not sure if it's correct?

I created my configs online with RRF config tool.

But looking at the homedelta.g file doesn't make sense to me

; called to home all towers on a delta printer

; generated by RepRapFirmware Configuration Tool on Sun Mar 25 2018 16:56:23 GMT-0400 (Eastern Daylight Time)
G91 ; relative positioning
G1 S1 X322 Y322 Z322 F1800 ; move all towers to the high end stopping at the endstops (first pass)
G1 X-5 Y-5 Z-5 F1800 S2 ; go down a few mm
G1 S1 X10 Y10 Z10 F360 ; move all towers up once more (second pass)
G1 Z-5 F6000 ; move down a few mm so that the nozzle can be centred
G90 ; absolute positioning
G1 X0 Y0 F6000 ; move X+Y to the centre

looks like its sending the x y past its travel distance
then it moving the Z-5 that would crash into the build plate
I always had mine set to z0 at build plate and up from there to enstops
First time setting up duet so maybe i have to do things different than what i use to

Thanks Gary

That looks correct, assuming that your carriages never start more than 322mm below the point at which they trigger the endstop switches.

I set it in the RRF for 315 so should i change it to 315,?

You don't need to set it to 315 as long as it is larger than 315 (i.e. 322) since it wants to ensure your carriages hit the endstops during homing
