The gilded cannonball is ready. It’s so cool I made myself one too, to carry on me. Artists need gold-leafed 6lb cast iron spheres so often!
accu.co.uk is a very dangerous website for me. I needed to buy screws and nuts for a client project.
Yep, my own collection got some new sizes. Judge me if you want. My M8x20 says I don’t need to care.
Yep, should have ordered more acrylic.
This is not about cannonball gilding at all. I showed a friend a photo from the process of making his Christmas Present and he said he was in need of a cannonball, so that’s my code name for this. I have pictures of it being polished as well. But, as there’s a chance he might see this before Christmas, let me just say that the gilding powder picture came out badly.
Well, those lead screws didn’t need to be that long anyway.
Wait, they did? Oh. Well, let’s cut about 5mm out of this solid block of aluminium and add in some washers … there…
*lead screw falls out*
And use the pulley grub screws to hold everything together against the backlash. It’ll be fiiiiiiine.
If necessary, I can put the solid block of aluminium on the other side of the metal it’s attached to right now, and that’ll tighten things up, although I’d need to take some more length off the lead screws. That could never go wrong.
I need to mess with the PID loop on the 3D printer. Right now it’s got about 12 possible temperature states in a look-up table, and that’s not enough. It needs 60, I think. The symptom is that the print never starts, and I believe that’s because the temperature never stabilises enough. If the change in loop doesn’t fix it, I’ll end up using an Arduino/Ramps combo, but I need to do this.
I’ve needed to do it for about five months now. I do not want to flash that damned thing Yet Again. For one thing, it’s been months since I have and I’ve forgotten most of the steps.
Update: Have accidentally ordered an Arduino Mega to go with the early RAMPS board I picked up. I was on eBay and it fell into my basket.
