As my dear sweet wife would say: "At what point do you admit you bought the wrong machine and just throw the whole thing away?"
Progress looks great!
In truth, had I just shelled out at the beginning for something like an openbuilds kit, I would have likely spent FAR less on this particular venture...
But...I'm simultaneously always thirsty for knowledge, and an absolute cheapskate. So overall...I'd say the journey has been worth it.
CNC is the sort of thing that is best digested in little bits and pieces. New vocabulary to be learned, new skills, picking up little things like simple Gcode commands, macros, probing...
And there's enough variability in machines that what works for one may not work for another. Say you have a particular problem...like "ah, shit, I need to figure out my zero points here, but my workpiece is non-conductive!".
Well...there's a few different ways to handle something like that. You might buy an aluminum plate that comes with a set of macros that include a g-code command that makes your machine say "NO. no. I ain't doing that shit". Well...then you gotta figure out what the problem is.
It can be a headache, but it's scratching my itch for intellectual stimulation.
As of right now...I had a little hiccup with my X-axis: I couldn't get the damn thing to move when commanding individual 0.1mm travel commands.
I think I've got it narrowed down to a poor setup on my part...the eccentric spacers on my v slot wheel bearings were a bit too tight, and I needed to lube up the lead screw. I took the opportunity to add an extra plate on the backside of the gantry and four extra wheels to share the load.
More creations to come...
