Because I don't have end stops I cannot tell the machine to move until it reached it's home position, and over time as I reset it, tweak and fiddle with it, the Cupcake CNC loses it's place. This manifests when I attempt to start a print and the Cupcake attempts to center itself but instead crashes a platform against the hard limits. The fix for this is to add the minimum end stops. The current feeling in the reprap community is to use micro switches as they are cheap and more precise than opto end stops however all the mountings on a Cupcake CNC are designed for opto end stops. I've not managed to attach these end stops and got it working well. Pressing the home button would move the X, Y and Z axes to their minimum positions accurately. It still requires the end stops to be fixed more securely, but it pretty much works. | Because I don't have end stops I cannot tell the machine to move until it reached it's home position, and over time as I reset it, tweak and fiddle with it, the Cupcake CNC loses it's place.

Unfortunately I could not sort out the extruder, I'm also a little unsure how to proceed. My Greg's & MK4 hotend is a complete bodge and while it works it is very unstable and wobbles a lot. My hobbed bolt seems to default to stripping the filament which stops it from driving it down into the hot end, this could be caused by the bodged extruder combined with a MK4 hot end or a poor hobbed bolt. | |||
