I got the warp out of the glass today. Brought it up to about 800 degrees slowly, and of course contained incase it grenaded. It's silly to think it would crack a cooktop, it's not a bomb, just a potential source of hot shrapnel. I managed to get it where there wasn't a 1-2mm bow in the middle. It's still not perfect, so I'm still waiting on a chunk of pyrex that'll hopefully be a little flaby Snarky - Reprappers
New updates. X,Y,Z axes all working properly. Hotend and Heated bed functioning properly. Raspi remote controller functioning properly. Still can't print. Latest problem is relatively easy. My heated bed glass is warped like crazy. It's tempered glass. I'm not sure if it came warped or has just warped since I got it. But I tested it with a straight edge, it's way out of whack. I can proby Snarky - Reprappers
I wanted to post about a few things I've figured out with my Reprap. Z-Axis problems Previously I had thought that issues I was experiencing with the z-axis were related to various things. Possibly the power supply, possibly the fact that my motors are wired in parallel instead of series, maybe in stepper driver voltage. Nope. I'm using RAMPS 1.4 with an Arduino Mega. I bought it preassemblby Snarky - Reprappers
Well, I figured I would make a new update today. There's quite a lot of trials and tribulations associated with this project. I suppose I should start by addressing the previous to do list and see what's been accomplished and what hasn't, then move on to new issues. Hardware to do list: Figure out why leds wont turn off with remote. (goes to green, possible grounding short) Solved, it was soby Snarky - Reprappers
It's computer wire sleeving used in computer modding. Plastic, fairly heat tolerant, you ignite it and it generally extinguishes itself. I covered all the wires in it to both combine strands and add protection against abrasion from the threaded rod. It's available in electronics stores here in Texas, but you can get it online at places like amazon. Plastic conduit would be nice, but I've onlyby Snarky - Reprappers
No, the stepper motors are wired up using their stock harnesses from the factory, and the hot end is wired up with a relatively thick single strand copper wire.by Snarky - Reprappers
I started building my first raprap a couple of days ago. I wanted to show off my progress a bit while I take a break. I opted to build an Prusa Mendel i2 as the parts seemed readily available. I'm also integrating a Raspberry Pi into the printer for control. I think other than some wire clean up and rerouting, I'm down to the software aspect of the build; which is probably the most frustratby Snarky - Reprappers
Thermal conductivity is important. Copper would be one of the "best" choices when it comes to common metals with high thermal conductivity, but it is very soft and is prone to oxidation as a bare metal. Therefore brass is used; it is alloy an of copper and zinc that is known for it's anti-corrosion properties, low friction properties, and strength. The brass used probably is high brass with aby Snarky - Mechanics
Okay, so the most important aspect of this print would obviously be a knowledge of engines and of course indepth research on this particular one. The engine wasn't manufactured in one piece, so it shouldn't be printed in one piece. That means the largest piece of this or any engine will be the main block where all the parts bolt into. From the pictures, it looks to be a 2 piece affair, with thby Snarky - General
I'm very interested in 3D printed weapons, but only as an intellectual and legal exercise. Just because someone else put plans on the internet doesn't make them liable for your actions. That goes for hotends or printed products. The only way to sue Cody Wilson for your injuries and actually get a judgement with any meaning towards him would be to do so in a Texas court (where he resides). As a rby Snarky - General
Cool, it's nice to see that if you have too large of an image, it doesn't do wonky things to the actual thread. Though it would be nice if the site shrank the image to fit instead of truncating. Oh well, a successful test, it's interesting to see that 'every' method of posting works. I would guess that the "large" size is the best size of optimum viewing without truncating or forcing peopleby Snarky - Sandbox
I'm getting ready to start a build soon, I wanted to document it on these forums. I'm testing smugmug as the image host, I wanted to see the various image options tested. It's all the same image, through the different post methods.
