Setworks Project...your input is requested
« on: July 11, 2017, 01:04:50 pm »
I started thinking about whether or not the SimpleSet could be modified to do more after finishing this DRO project last fall (http://www.forestryforum.com/board/index.php/topic,93251.msg1436333.html#msg1436333) and decided my goal would be to create a direct replacement for the WM SimpleSet controller that would provide more avanced setworks features without modifying the existing SimpleSet(enclosure,button-panel,encoder).

This is the first experimental prototype done on proto-board:
 

 

 

 

I was able to test and prove the basic functions using this prototype but the microprocessor was too small to add the functions needed to make a usable setworks.  A new circuit board was needed but I couldn't see doing any more of that hand wiring...it was time to learn how to make an actual printed circuit board.  So, YouTube to the rescue and a few weeks later...

 

  
The circuit design is laser-jet printed onto shipping label backing paper and heat transferred to both sides of a bare copper board using a modified laminating machine. 



  
Etching the board using a mix of muratic acid and hydrogen peroxide.  The print toner resists the etching solution and anything not covered by toner is etched away.



  
After etching, the toner is wiped off with a solvent and the bare copper circuit is left behind.



  
The board is tinned with a tinning solution to protect the copper and the holes have been drilled and is ready for the components to be inserted.



  
Fully populated prototype PCB. 



  
The WM SimpleSet controller for comparison.



 
As you can see there have been "a couple" of design changes to the board since I made it.  These will be incorporated into the next version.


That's it for the show-and-tell for the moment.  I think I've got most of the bugs worked out and I hope to have a riveting video of the setworks in action in the next day or two.

I need y'alls help deciding what to call the different sawing modes.  There are two sawing modes other than Manual:

MODE1:  Starting at the current blade height, calculates the drop(target) points based on the selected SET(desired board thickness) and kerf, so that a board of thickness SET is left on the bed.  Optionally a CORE(leave on) value can be selected and that will be what is "left behind" on the bed after all SET's have been cut.  This Mode is similar to Pattern mode on the Accuset2 but with only two increments available so I don't really want to call it Pattern mode.  It is the same as the AutoSaw on the TK mills accept for the added CORE option. 

MODE2:  From the current blade height, drop the selected SET value plus kerf.  This is the same as the SimpleSet and AutoDown on the Accuset2.

I need to name these two sawing modes something that can be spelled or abbreviated in 3 to 5 letters.

Suggestions?

Excellent work....I can do mechanical work but electronics is pretty much magic to me.

On WM mills, what are they using to sense movement?  Do they have a rotary encoder on the lift mechanism or something else?

It may not be practical to add to an older machine like mine ('87 LT40), but since I'm going to all the trouble to add hydraulics I'd consider adding set-works if it wasn't too difficult.

first off, hats off, and you brought back memories from my brother Kev, you and he would most likely have hit it off.  That said, TAG for the pattern mode, DRP for the auto down, not sure what else works.  if you went four letters, TARG. and Drop,  kinda a no brainer,  either way impressive, innovative, to say the least. 
only have a few chain saws I'm not suppose to use, but will at times, one dog Dolly, pretty good dog, just not sure what for yet,  working on getting the gardening back in order, and kinda thinking on maybe a small bbq bizz,  thinking about it,

So you can do all that but not name it lol lol


Nice work!  I can't even begin to comphrehend (or spell it lol) how this all works..


Two questions, do you have it so that it won't drop the head below say 1"?


In your mode one, there's only one way to drop to the bed while leaving a core, so how can you start at where the blade is currently?  In pattern mode it drops down to the first spot, and if you didn't use pattern mode to come in on a slab you'll have a burn board.


I think you call mode 1 core and mode 2 down...its just a name maybe call mode one goat and mode two $300 lol

I have it programmed so it won't drop below 7/8" except in manual mode.  I guess I didn't explain Mode1 very well.  It doesn't make the first cut where the blade is but rather it drops to the nearest calculated target(or spot if you like) below the blade for the first cut.  It's just like Pattern Mode on the Accuset2 but with only two increments available.

Here's some Wood-Mizereze copied from the WM manual and modified to fit my Mode1:

Mode1: This mode references the bed and allows you to program up to two different increments (SET and CORE) calculated up from the bed.  The SET increment repeats itself up to the starting blade height.  The CORE increment indicates the size of the remaining cant when all of the SET increments have been completed.

The mills equipped with SimpleSet use an absolute rotary encoder installed on the input shaft of the gear box.  I don't think the SimpleSet has the adjustability required to make it work accurately on an older mill but an after-market setworks could probably be made to work.

As promised here's the video.  I haven't a clue what I'm doing when it comes to making videos.  Please be kind. :)

This is unbelievable Paul.
Did I hear you say Goat Mode????

How did you get the face of the Simple Set with the new labels on?
I tell ya.....I like it bud.
Good job!  8)

Awesome job! I love the part about being able to actually adjust the kerf width, since I plan to use .055 and .045 blades with different kerfs when my LX 450. The keyboard overlay was a nice touch.

Are you going to make this available for simple set owners who want to install this on their own mills? If so, any idea of what the cost will be? I suspect you'll sell more than a few.

Thanks guys.

Yes, "GOAT MODE" is in the lead at the moment.  The buttons were drawn using OpenOffice Draw, printed on self-adhesive address labels, and covered with self-sealing(no heat) laminating sheet.  At some point I'd like to have some vinyl stickers made...I've found some on-line places that will do small runs pretty cheap.

Stuart:  I hope to, eventually.  Haven't decided yet on a price.

I'm very impressed and like it a lot.  Does any other setworks have the center function?  I could use that a lot. 

Your presentation was first class, thanks for the preview. :)

Great video....I especially like the center function.  I've never been around a set-works but this would save a ton of time.
If I get the modifications done on my mill I may be picking your brain about what it would take to put one together.

Larry-- I don't know of any setworks out there that have a set center function.  I just know I spend a lot of time measuring the center height of logs and and counting up in my head, trying to get cants centered.
