Help with process printing

[MontyFlange]

Trying a 2 colour print using processes. Set the first one to print, goes fine, but the object is to tall for the next proses.

The 1st print finished. I change filament. Start print 2 but print 1 then gets knocked over or trapped by the X carriage bars as it moves to the front.

Any way of stopping the bed going up at the start of the build until the carriage is at the front and ready to print ?

You can edit the starting script if you want to change what it does at the start of the print

Edit it to what ? Pray tell.

You can use whatever you want. So many people prefer different functionality at the start, that they just made it totally customizable.

If you haven't looked at gcode before, then this link may be helpful: http://reprap.org/wiki/G-code

All of the movements are G1 commands, so you're probably looking for one of those to change
