Just a small rant: Friends don't let friends use Sprinter.

the movement code should be very similar between the two, as they’re both from grbl.

Well I’m using Marlin and find the extruder clunks into place at the end of travel. I thought I was the only one, but I’m told the problem is with the firmware and that changing to Repetiere fixes it. Anyone recognise that? I should video it and post it to G+.

@Chris_Roberts_chrisj , do you have DISABLE_E enabled in firmware? That clunk may be your extruder axis disabling if you have that feature enabled. Also, yeah - post a video on it.

@Matt_Kraemer1 that is worth the price of admission, which sadly is only about 20-30 minutes of notepad hacking.
