Repetier-Host start/stop gcode for TAZ

Chris Anderson/ September 7, 2014/ Uncategorized/ 0 comments

Here is my Repetier-Host start and stop gcode settings that I am using for my home built TAZ.  Using these settings in the new Cura Engine slicer – love it!  These commands can be used on other printers with some minor tweaks.  Key features is the system does not zero the Z axis on x/y 0/0 but moves a little bit from the corner 20/20 in order for the head to clear the glass plate clip.  The other key feature is how the printer then after zeroing the axises moves up a purges some material before starting print.  These setting help tremendously with printing remote and not having to babysit printer so much.


These gcode setting should work with other slicers also – also some of the dynamic variables may need to be changed
