I see someone 4 years ago had the same problem and never answered! "swap' was not declared in this scope" probably the most common problem with downloaded code. What does it mean, not declared in this scope? void SWTFT::drawLine3Byte(int16_t x0, int16_t y0, int16_t x1, int16_t y1, uint8_t r, uint8_t g, uint8_t b) { int16_t steep = abs(y1 - y0) > abs(x1 - x0); if (steep) { swap(x0, y0); This swap is found, declared in this scope swap(x1, y1); This swap is found, declared in this scope } if (x0 > x1) { swap(x0, x1); This swap is not declared in this scope swap(y0, y1); }Thanks,Ralph

Thanks for the reply. Well first thing is I am using a CUI AMT103 rotary Encoder (https://www.cuidevices.com/product/resource/amt10.pdf). Otherwise I match your setup. I have it set for 800 PPR (Pulse Per Rev).

Wow, Thanks for posting. Far beyond my patience level.

No output to Monitor!Still trying to get this to work!!At least your code compiles with out errors!

If the lasers are fixed and you lower or raise the table are they still aligned on the table?

Wow, I almost dare to try, thanks!!

I guess I'll have to make one, if I ever get my 3D printer working again.I cannot see how you get anything but a circle.It would be nice to see the holder in the middle of the paper drawing the shape. Oh well.

What do you stand on to get up to the eye piece? I'd like to see some pictures of it in use. Thos e are some beautiful hills in the background, great colors.

What Stepper motors did you use? What torque?Great project, ThanksRalph

I am getting a "redefinition of 'void setup()'" error

Bull, I agree with okrad123. It is misleading/misservice to call it Radar.

Is the power door lock actuator energized all of the time?

Nice, but how many people have a metal bed on the 3d printer? All of mine have plastic or wood beds.Ralph

How hot can Lexan (the separator) get?Great post thank you.Ralph

WOW, great instructions, thank you.

WOW, thank you so much!! Now to find the time ...Ralph

Thanks that is what I was looking for.Seems like you should have included setting the teeth in your video. As it is the saw blade illustrated is useless.

At the begging of the great video you hammer the teeth removing the set.Then you flatten the teeth and proceed to sharpening the teeth using your great device.How do you re-set the teeth? As it looks you have nicely sharpened angles all in a straight line I do not see how that would cut very well without set to the teeth.Ralph

Great project, thanks I need something similar.Some Europeans call welding soldering.Ralph

Wow, great write up, great project.Thinking of a electric motorcycle has been lurking in the back of my mind for a while now, one step closer.ThanksRalph

Nice, thank you. I need one plus a motorized one as well.Ralph

Wow great able, I have similar project in mind. Thanks for all of the links to similar projects that will really help to go through them all.Ralph

FLQPKNL9MB, having a little trouble understanding exactly what you are saying.To begin what do you mean "the chuck fits as a cone"? Then I know you cannot (well should not) use a drill press as a mill where one applies lateral stress (pushing) against the spindle (chuck) but would turning wood produce that much lateral stress? It would be working in a shearing motion not a milling motion. Thanks for the reply.

Nice thank you for posting.I have been"thinking" of using my Drill Press as a vertical wood lath.Has anybody ever done that?Ralph

Wow, I have seen other attempts at explaining PCB with CNC but none explained it as well and comprehensively as you have. Thank you!!CNC PCB has been on my list for a long time maybe now it is getting closer.Ralph

NIce, thanks for posting.Ralph

What is this? Very interesting, thanks.

Thanks interestingRalph

Why are they called "Stressed Skin Panels"??Where does the stress com from?Thanks for the instructable, hopefully I will eventually get around to using it.Ralph

oops Download is working it is just such a small file my browser did not detect it downloading.

Nice marking knife, but better yet is how you work in a small shop. You have everything thought out, like your metal vice clamped in your wood viceand other items.Thank you for posting.Ralph

The download is not working!!

Wow simply WOW!! Great project thanks for posting.

I have been thinking of doing this before the sheetrock went up.That of course means lots of cuts and fittings of the sheet rock.Lately I have been "think" of doing the shelves after the sheetrock went upbut was not sure about the strength. Thanks for the Instructable, now I no longer have any excuses.Ralph

Thanks, finally someone has thought this out for me. Been "thinking" of doing this for a few years but never took the time to think out the details. THANK YOU!Ralph

Nice, thanks for posting.Ralph

PCBWAY sales is really stupid, unable to order PCB.

It was the top downloads link on the Instructable page.It is working now!!Ralph

The Download link!!

Download link not working!!difnitely want this, thanks for posting.Ralph

Really a pretty shop. But what happens when you add another screwdriver or file or ...I am just now setting up my shop and thinking about organization of hand tools and power tools. I have gotten some great ideas off Family Handy Man.

Not working!!I have no voltage at Vref.This is with two panucatt Devices 8825 and a Ramps 8825.Really getting depressed.Two years ago I had the panucat devices workng.Ralph

Now that welding table at your job is impressive.Looks like 1" thick 4' x 20' steel.Great ible thanks, definitely on my to do list!Ralph

Nice, thank you for posting!But why cut the notches with a chisel? Why not cut the sides with your back saw and chisel the bottom?Ralph

I "thought" I had tried every combination, but ...It works great in both directions!!I can turn the knob really fast and do not see any problems.I do not appear to have any problem with bounce. Thanks again for the 'able' .Now I have to understand your code.Ralph

Well it is working!!Turns out the center pin was ground!!Wooowee, thank you Sinom!!

I have tried every wiring possibility.And will do it again :-)Ralph

Thank you Simon for the reply.Yes, if I reverse the wires it is just the opposite, no increment.It only works on every detent in one direction.I tried with a different encoder, one that has no detents and everyfull turn increments and decrements correctly.Ralph

Hi Simon, thank you for able, My encoder is a no name ebay encoder.It works great for increment but does not decrement.On increment every detent is counted on decrement sometimes one sometimes 2 sometimes 13 sometimes 23 detents are passed before a decrement shows up.Depending on which wires to pin 2 and 3 I can get increment or decrement but not both.Without decrement it is not really usable!Ralph

I wondered what it would take to make a generator.

WOW, great, Thank You for posting!!600 watts =0.804613 hp that is amazing.I am surprised a standard run of mill ESC is all you need.This gives me so many ideas.Of course I do not have the 3D printing capabilities but still...Thanks again,Ralph

Thanks, any idea of lifting capacity? Your table saw might be 50# - 70#.

WOW, absolutely WOW. I have always wanted to do this.Now I do not have any excuses, well I do not have a laser or cnc router (yet).This is really beautiful, thank you!!re:After I get the wire red hot, I dunk it in some water and voila! Soft, easy to work with metal.Actually you are case hardening the wire when you dunk it. Just let it air cool to be truly tempered. Case hardening just hardens the outside layer of the wire the inside stays soft, possible you are using the hardening effect.Anyway I love it, thanks again.

Thanks AeroSpaceWatercraft, that's what I am considering.This would be just an one time use so I do not think I care that the cornstarch and the detergent burned away as long as the sand held it's shape while the metal filled the mould. Of course I do not even know what green sand might cost.

well that might leave a grainy casting, as long as the sand held the shape it might be interesting. But thanks for the reply.

Could one use this as a mold? In place of green sand?

the thing is that all that should be done within the interrupt is the counter is increased period. Nothing else. If you need a delay do it outside of the interrupt.

Your interrupt does not look very efficient, I thought one wants to be in and out of an interrupt as fast as possible, you even have a delay in it. Of course as you are only doing one thing it probable does not matter. I would be doing more things.

Wow, thanks that explains it!!

Nice article, thank you!!re:Step 6: Countersink the HolesWhy would you bother countersinking the holes?The hole is covered by the insert, the screw head sinks/sets in the insertnot the tool.

Great, thank you for posting. Very nice dies I would like some instruction on machining them.

WOW, sets all sorts of ideas afloat in my head! Thanks

The Sketchup download does not work!!The download is a random name.tmp file that is not a .sch

could you send me a nag for taking the class, it is all so interesting and someday I will need it but not now, so it is not high on my to-do list but maybe with some nagging....

Thanks for the replies, that is very interesting. I will stick with X Left/Right Y Front/Back and Z Up/Down

Great article thanks. None of my 3D experience ever had Y as the up-axis. X front back Y left right Z up down. If you do not believe Y should be up down why promulgate the idea? Or is that Fusion references the axis?

"I can see that the surface to be cut is actually taller than the material to be cut, so not I need to scale the surface down in the Y dimension"Shouldn't that be Z dimension?

First thing THANKS EVERYONE FOR YOUR CONTRIBUTIONS!!I finally got it working thanks to your help!!markwills, it was your code that finally worked.Now what /why are the pins defined?#define En_pin 2#define Rw_pin 1#define Rs_pin 0#define D4_pin 4#define D5_pin 5#define D6_pin 6#define D7_pin 7#define BACKLIGHT 3How would they be used?Thanks again,Ralph

Hope someone is still monitoring this thread.I ran the blink code and the LED blinks rapidly BUT then it stops!!The On led is now on and the SCK led is slowly blinking but the led on Pin 14 no longer blinks!!

actually some recommend not drilling in straight lines, it helps to hold yourcomponents while they are being soldered if some of the holes are offset!

Thank you!!

Technically any "paper" that light will diffuse through, actually any material could be used like toilet paper etc.

Thank you, the lathe work is just what I need as I am just starting out machining, and then the heat treating loved it short and informative!!

now how to put a potentiometer to control speed?Thanks for instructable

djalmao23, says it works with a 5A/12V CC motor.I would like to know the max amperage, also what modifications are needed to handle a heavier load?
