It's been a while since I last posted, but that doesn't mean nothing has been happening. I've finished connecting the wiring for the stepper motors, and am currently in the process of sourcing bearings, bolts and tubing so I can assemble my extruder and its carriage. I've also got some STL files for 3D-printable endstop mounts, which I'll get around to printing and testing at some point... Because this is all unfamiliar I'm taking things slowly at the moment.
Since all the motors are hooked up now, I connected the printer to a power supply last week (with supervision of course). The good news is that all the motors are in working order, yay! Here's a very short video of my printer's first movements:
Like most babies' first steps, hers were jerky and hesitant. Unfortunately this is at least partly because the threaded rods on the z axis aren't 100% straight - it's such a slight bowing that a human can barely see it, but it's more than enough to upset a robot. After a bit of oiling things started to run more smoothly, but needless to say I'll be keeping an eye on this.
Obviously there are a few things on the go right now. I'll report back when something else interesting happens :p
