CNC Router Tool Presetters For Sale

[JoeyGH]

Hello all. I'm a tool maker and like many of you have built my own router. I recently thought up a simple but very effective Router Tool Height Setter. This was custom designed and built by me.

It is made from 6061 aluminum and S-7. The S-7 was pressed into the top slide piece to increase useful tool life. The purpose of this device is to elimate the need to touch off your tools on your cnc router. All you have to do is wire the switch included inside this device to a limit switch on your router.

Then configure Mach 3 or whichever software you use to use it as a tool height setter. This device measures up to be approx. 2''x2''x2 1/4". Mounting it to your router's table is made easy by pulling off the top slide plate and putting screws of your choice through the two counterbore holes.

My current price is $29.99 plus shipping.

Hi,
I would like to know how to use the setter. Please describe in more detail the way to zero the setter, what electronics are involved, one photo seems to show a digital display in the background - it this part of the setter? What are the spiral tracks on the pillars?

Your are asking people to part with money having not seen the item at all, or being provided with much information on how it works. More info is definitely needed.

Thanks.
Bevin

Sorry about that Bevin. To clear up any confusion. You mount it to the table as it's sitting in the picture to the left. The spiral tracks running up the posts(which by the way are dowels pins) are springs. They suspend the top plate while the dowel pins make everything travel in a linear fashion. To use this device all you would do is mount it to your cnc router's table. Then attach the switch that's inside this device to one of your limit switches that are already on your machine. Then you configure Mach 3 or which ever cnc controller you are using to use it as a presetter. For example If I was working a on a piece of mdf(pressed board) and it was .500 or 1/2 inch thick I would program it to cut at .490 inch in my program(which would cut .010 inches into my part). Then I would make my router touch off on this presetter with a known distance from the table up. We'll say for example the switch activates at 1.792 from the table up. So when my tool activates the switch my tool would be exactly 1.792 inchs above the table. At this point the router now know's the Z offset for that tool and can go ahead and move to the start of the program and drop to the .490 above the table at this point the table would be considered a Z of 0.000 inches. Sounds alot more complicated than it really is, but it illiminates the need to touch off your tool manually. Hence saving you time and possibly money in a commericial environment. It's usefulness would greatly increase if you have a tool changer. Also if you already touched off with a brand new tool and made a cut and then ran some more pieces you could have it touch off each time and make sure your tool isn't breaking down. If so you could have it "throw an alarm" and you could change the tool without incident. Well any other ?'s are welcome. Hope all this helped thanks.
