Thanks Cody Wilson. Thanks for pushing the 3D-printed gun in everyone's face. Thanks for making every 3D printer a 'potential weapons factory'. Thanks for helping to 'criminalize' 3D printing. As per usual, Mr. Wilson don't have to bear the costs of his hubris - this shop owner does.by akhlut - General

Did you plug them in the right way? The pot is in a different position on the pololu DRV8825.by akhlut - RAMPS Electronics
I guess that's the new Stratasys pricing?by akhlut - General
That heat + pressure *might* work. Take the racks out of your oven and build a platform out of bricks on the floor of the oven. Sandwich the garolite between 2 baking sheets. Line the top baking pan with some tin foil then load it up with some more bricks. Pop it in the oven, set it to 240F and let it go for an hour or two? Mcmaster says Max temp for LE is 235F - exceeding this a little bitby akhlut - General
First, I'd run the machine through some prints and see if you're skipping steps or going into thermal shutdown on the A4988's. Just be prepared to actively cool the stepper drivers with a fan or two. If you max out the 1A that the pololu's are delivering and are skipping steps, then it may be time to reconsider some things. Those Wantai's need an awful lot of current, a lot more than the 1 ~ 1by akhlut - RAMPS Electronics
I've got a couple of MKII's sitting on my desk, taunting me. I need to finish retrofitting my machine to use them though. Soon.by akhlut - General
OK. Glad to know it's on your radar. Thanks!by akhlut - Administration, Announcements, Policy

Greetings admins! I can't seem to post because I'm using a 'banned" word, and I'm having a difficult time figuring out what the banned word is. What words are banned?by akhlut - Administration, Announcements, Policy
I backed it just because it's an interesting idea. And for $120 how can you go wrong?by akhlut - General
A few hundred bucks? I spent about $100 on a chamber that fits two machine and holds temp at 45C.by akhlut - General
To reduce warping, get the machine off your desk, reduce odor, etc. Chambers may be expensive to produce in the short-run, but if they're thermally efficient they can be very inexpensive to operate in the long-run. I've tried the turkey bag method before with mixed results. It's why I built a heated chamber. That and you're radiating/wasting all that energy. Better to leverage that trappedby akhlut - General
+1 for 45C I don't have any insulation, but the box is pretty air-tight. It's hot in the summer, but in the winter my office is nice and cozy.by akhlut - General
If the fridge is sealed, why bother heating outside air and forcing it in? Why not just place the heating element inside the fridge and heat/recirculate that air pocket? Much more efficient. But even an old freezer/refrigerator would work. Store the filament on a bar in the freezer and feed it down into the fridge via a hole drilled between the chambers.by akhlut - General
I took a cheap electric heater and separated the control circuit for the fan and the heater to be separate. The fan got it's own cord so that is could be constantly on to re-circulate the air in the chamber. The heating element remains wired up to the controls and original cord for manual on/off. Operation is straight-forward. Plug the fan cord into the power-strip so that it's always on foby akhlut - General
Can we get a look at the lathe that you're going to convert?by akhlut - General
What stepper motors are you going to use?by akhlut - General
There really is no need for the arduino. You can certainly use a 4-axis BOB and PC to control a reprap. Without the arduino you'll need some extra hardware to make it all work, but nothing is impossible. I know that slic3r can export a MACH3 flavored g-code. Reprap uses the arduino platform because it is cheap, modular and easily procured. Honestly, there are no secrets. Perhaps the inforby akhlut - General
For all you folks whining about NPR and PBS why aren't you complaining about the egregious tax system that is rigged in favor of massive corporations. It's complex because corporations have paid for it to be that way. But let's talk numbers. I like numbers.

Robin2, you're really asking this in the wrong place. While some here may have experience with milling machines and CNC lathes, it's not what we do. Perhaps here. We build 3D printers that, with our aid, self-replicate. That is our only goal. Additive lathes have been discussed in the past, but I don't think I've seen any results on that front. You don't 'wire GRBL up' to anything. It's fby akhlut - General
I imagine you wind the filament on the 'tube', epoxy it, then bag and vac it. Being able to make a custom shaft for my Werner Molokai would be supersweet.by akhlut - General
This is looking VERY interesting. Where's you booth at makerfaire? I will definitely be stopping by.by akhlut - General
I started out making my own hobbed bolts. They were successful, but crude. Then I decided to spring for a hyena bar. Totally worth it.by akhlut - Reprappers
