Description
A little bucket designed to hold small priming pellets made during the Print_Start macro.
There are 2 versions of it, one that simply bolts to the front of the frame, and the other is held in place by 2 6mmx3mm magnets to allow for easy removal/dumping of the pellets.
Each version has a 250/300/350 size bucket. Tested and confirmed fit on a 350 but the smaller sizes should fit.
I have provided an example (I have been using for over a month) of the priming macro below. This is for a 350 and it assumes you have already leveled the bed/gantry and have the proper z offset/auto_z calibration.
Obviously, use this macro as a guide/reference and check it over and understand what it is doing before going full send on it.
