effector collison with starting g-code #69

When printing my printer goes to extrude the outside strip and hits one of the bed clips. Is there any other start g-code that can fix this. Thanks

Your issue sounds like an issue in a similar vein to issues, #11 and #19. The nozzle should be able to clear the bed clips, but in some machines this not the case. The links above point to some remedies and as you suggest, it is possible to modify the start-up g-code.

The snippet below is taken from the start-up g-code. The three "54s" in the second and third lines sets a 54mm radius for the priming strip -- you can change these "54s" to another value to set a more suitable radius (e.g. 50).
