You also have to consider how much of the landscape changed, deforestation and agriculture in particular, that could have had an effect as well. Trees in particular absorb a lot of sunlight and if...

So I don't have a link to the video yet, but I started it up with the panel off and the plastic piece with the foam cleaning pads seems to have a homing switch of some kind since the print head...

Under that top panel you can see the main part of the printer that we'll be using for our pcb's, it holds the print head, all the sensors, and the control board with power and serial connections. I'm...

On the bottom of the top panel it looks like the top is pretty simple, the ribbon goes right to the scanner head itself and directly to the buttons themselves, since there's no ic on the button pcb...

Right underneath the panel are two ribbon connectors linking the button panel and the scanning head to the main control board, both will have to be removed to safely lift the top panel off. It looks...

First is a picture of our organ donor, a pretty simple desktop printer, luckily it makes pretty good prints on paper, but the wife an I want to keep our wireless printer for home use, so its either...

Hello CNC zone. Hopefully I'm posting this in the right place, if not I'll move it right away. I've been reading quite a bit of the diy servo drives of both the atmega and arm stm32f103c8t6, the arm...

Im working on a C++ lesson from Udemy, John from cave of programming has it and it seems pretty good. So I've been looking at the files in marlin 360 in case I can borrow any of the code and it looks...

Nobody? If I do find a way to make this controller work or any other info on this I'll post here so people can learn more about this.

Right now I'm searching through the marlin 360 and grbl...

Hello, sorry if I posted this in the wrong area, but I'm working on making a cnc routing machine that has two linear and one rotational axis, similar to a polar 3d printer. The reason for this...

I'm pretty sure in the video he says the only parts not built from scratch were headstock and grinder spindles. Those linear air bearings don't look mass produced and if he mentioned the spindles as...

Hello, I was checking out a couple of air bearing spindles on ebay and was wondering if anyone had any idea of how they were wired for the motor and encoder. The first one I was looking at was...

I'll see if I can, I'm still new to Fusion 360 but we'll see if that'll work, thanks a lot for those numbers.



That's way deeper than most any cut I would be doing with this machine, since...

I couldn't find anything on the manufacturers site, just static and dynamic load ratings (and torque of course) I'm not sure even contacting the manufacturer would help though since the shorter ways...

I should make a quick correction, I made a silly mistake in Fusion 360 and put 100kN PRESSURE on the ways, which apparently distributes the force very evenly across the entire surface. Instead, I...

According to the sim at least, the base itself will be rigid enough to hold over 100kN with less than 0.00002" deflection translated to the carriage/cross slide when filled with plain epoxy, not even...

That's not too bad, Pretty much anything I'd be using the lathe for would be about the same size as what I would have on a mini lathe. The extra travel is for light duty milling in aluminum or for...

I've discovered the Fusion 360 program, since I don't make anywhere near 100k per year yet I can use it for free, and it really is an awesome program. I tried modelling my space frame design on its...

Ok, I revisited the IKO bearing catalog and each 15mm bearing of the lwl series is rated at 3490 Newtons, which translate to 780ish lbs each, which times four would be about 3000 lbs that it can...

Well, I wasn't expecting the rails here, but my 1 and a half year old found my computer and started pressing buttons everywhere, most notably the big blue "BUY NOW" button on ebay. So now I've got...

I like that channel iron idea, I wanted to cut up an old tractor with a front loader on it, way too small for most any work so it wouldn't be missed much, had 6 inch channel iron pretty thick too,...

I'm planning on using some 1/4"+ flat iron welded to square tubing to make a place to bolt the rails, even if the curing epoxy does cause any warping, the steel can be made flat before drilling bolt...

If it were me, I'd make the spindle without adding the taper or anything else to the end, set it up in the finished machine, then add the taper with a bit of extra material on the flat then gradually...

Hello again everyone. Since my plans for the (polymer) concrete mill have been changing so much and put on hold for now, I figured I might build something a bit more practical in my small shop, a cnc...

Sorry for the long delay, I haven't forgotten about this thread yet. I've been slightly altering my design and even coming up with a few new ones in case my first doesn't work, I also managed to get...

I just got a shipment of tapered roller bearings (Chinese of course) off of eBay. The op originally mentioned the possibility of building his own headstock spindle so I thought I'd post a bit of what...

I am planning a lathe build as well, with some c channel I'm recycling from some old tractors out at the farm. Two kids keep me pretty busy but in hoping to build a pretty accurate machine too. I've...

WOW, that thing looks SOLID!!! I don't know if mine will be as rigid, I always wondered how a gantry system works in comparison to a turret design, it would seem like a gantry is like two turrets...

http://www.cnczone.com/forums/attachment.php?attachmentid=294848&stc=1 here are some sketches of my machine, not 100% accurate/proportional but should be enough to give you an idea what my goal is....

OK, I think I'll be going with ebrewste's idea of trying the design out without any concrete/cement or epoxy. I was comparing the benefits of a couple different mixes of cement and found that in...
