I have a 2000 Ford Focus where the seat finally gave out on the right hand side, turns out it's just a bad design whereby all the force on the right hand side of the seat is transferred to the left...

Hi all,

I have an old plotter I'm trying to actually convert to a paper cutter. I tried mouting an exacto-like rotary knife on it, but the plotter doesn't seem to maybe have enuf nuts yet to...

Oops. I didn't read your post correctly. You have a centronics connector. This is a parallel port connection.

You should be able to use a centronics parallel port cable to connect to it. Then you...

Hi, I have a ColorPro plotter and I got it work just fine.

First you need a 25 pin to 9 pin serial adapter. Then use a NULL Modem cable going to the PC.

I found that if you can save out *.PLT...

I didn't know this but the last "molding" video shows a car wheel - didn't know those were cast, but I guess of course that would make sense and be the fastest way :P

I'm big into metalcasting...

Well thankfully lasers are quite affordable nowadays and can be used to measure quite a few things :)

So if you used a plumb bob, would you :

1. make a small square block and mount the plumb...

Wouldn't you also be able to declare something "flat" by comparing it to a very taught string stretched between two posts?

Also, if you simply take an object, and spin it while you carve it (like...

Hi,

I would like to mention that I do not think that a machine, built by another machine, will always be slightly inferior. The main thing pointing to this, is that someone had to create the first...

Hi guys, machine vision is basically a bunch of graphics operations, for example, first the image is put thru a guassian filter, then they find the edges - for this they can use an algorithm known as...

Hi, if your plotter speaks HPGL, most CAD programs can be coerced to output HPGL (export as HPGL format), then you can go to a DOS window and do the following commands, for example:

mode...

Well to be honest I would not know for sure, but I would not doubt it, depending on the type of charcoal used. Aluminum is really a low melting point metal, and 4 lbs of charcoal is an entire bag....

Yes you are right, I was thinking about that too - when iron and steel get beyond a certain heat they lose their magnetic properties..so thanks you have answered it..

This link has a great explanation of how screw cutting first started, and notice the cool info about the guy who built the first accurate screw, he...

Um, since AL is non-ferrous, I don't think you can use inductive heating on it, since inductive heating relies on eddy currents from the magnetic field..since AL is not magnetic, it won't work - only...

High, head over to backyardmetalcasting.com and check out the forums, they have tons of info on Oil burner designs.

Hi, one benifit to using charcoal is because the charcoal touches the crucible, and transfers heat more effectively. So you wouldn't really want to hold the charcoal off of the crucible with bars....

Hi, this is possible to do by writing a "following" algorithm which walks the edge of the image. Firstly,however, for a digital photo image you need to do image enhancement using and edge detector...

Ok I got it to work again after I set the computer hardware to "normal PC" using Device Manager as the optimization file talked about. It made me re-activate windows though which was a little heart...

Help!

My god I swear I have tried everything...I've reinstalled Mach2, I've tried Mach3, I've scanned for spyware, I've disabled as many uneccesary services as I could..Mach2 just does not want to...

Couldn't you simply coat the screw with a thin layer of furnace cement or plaster of paris first, which could then be broken afterward to make room..

Aw crap you guys are right - I looked at the datasheet and it is only .7125N-m so yes 1.3lb/in is correct. Guess it's not so hot then. Should still be plenty powerful enough for a large belt driven...

I think the vertical is a good idea too - another advantage is it helps to eliminate backlash in the vertical direction at least.

At work they were tossing out a bunch of old electronic equipment. I scored quite a few steppers, including a few which are 1A 3.2 volt, and the online spec says they are 1.30 lbs/in torque! (wow)...

I was playing with the idea in my head of trying to build a CNC clothing cutter for patterns.. of course it would be more work than a small machine since it needs a large swing.

I'm not sure...

I've always found the TGA file format to be the easiest to write out to disk. Bitmaps (BMP) have a lot more header information and while they are not insanely difficult, TGA's only have one big...

Hi lepton,

At the place I work we build scientific instruments with stepper controllers and such in them. I hence knew that you could use a UCN5804B chip - since it's an all-in-one stepper motor...

I agree DeathAdder, some people can really abuse C++ and C. Using prefix operators is a surefire way to confuse the heck out of anyone. With C and C++ you can write clean efficient code without...

Cool. Yep Delphi is certainly nice, I like the form editor and RAD tools.

Although using pointers in Delphi is a pain in the arse! With that whole ^ syntax...confusing :p

But this isn't a...
