Something set wrong??

Post by Terry Davis »

Lately cabinets we have been building are extremely tight to assemble. My dado settings in Ecabs is set to "depth clearance .015 and fit clearance .020". In control nesting I have "cut through depth" set .035 just to get the bit to skim the wasteboard when cutting. We have the new flycut program that remembers wasteboard thickness, Dan Lopez had some problems setting this up when he was here installing our typewriter head and we are wondering if something may not be still set right that we have to maintain .035 cut through.

Terry,

You will want to check the diameter of tool/s being used to cut dados and make sure the Tool Manager listing for that given tool has the precise Diameter listed. Also, you will need to actually take a caliper and measure the depth of your dados to see if they are being cut to correct depth as designed, this will tell us if the Daylight of your tools is correct. If the daylight is not quite right, your tenons could be cut to incorrect thickness as well... regardless, you will need to take a calipers and measure your tooling and actual cuts to find out what exactly is not right in accordance to your settings in the Tool Manager or as you design your cabinets before the exact cause of the issues can be figured out.

OK Ryan here are the numbers, I made a new cabinet using all default Ecabinet clearances .375 depth, .01 clearance & fit, 50% material. Remeasured the bit @ .335 (resharpened Vortex compression) and cut out the parts.

Material .758 melamine
Dado .357 deep
.388 wide
Tenon .412 wide
.380 high
That makes the tenon .024 wide for the dado and it should be .010 smaller???

Terry,

Using the mortise depth you posted here compared to what it should be, it sounds like your daylights are off by approx. .028. What you will need to do is to reset everything. Basically, you will be starting over. This isn't that hard to do though. The first thing you will need to do is find your daylight manually. To do this you will need to remove your wasteboard and tableboard. You will need to bring a selected tool down and touch off on the plastic pegs, or aluminum extrusion, that supports your tableboard. Once you have touched that, move your z axis up the distance of your ideal tableboard(.75). This will be your manual measurement. Now you will need to go into the machine variables and set the original and actual spoilboard thickness's to your ideal tableboard(.75) and your switchspoil to 0.000. You will now measure the same tool using the sensor. Take the difference of the two values(what you measured and what the switch measured) and place this back into the switchspoil variable. Now you can remeasure all of your tools. Once you have measured all of your tools, take a quick measurement of your actual tableboard's (spoilboard's) thickness. Let's say it measures .72 inches. You will need to take your ideal tableboard thickness(.75) and subtract your actual(.72) to get .03 inches. Now, we will open the flycut routine and go to the table board section. It should tell you that your tableboard thickness is .75 inches. Under amount to remove, type in .035 (adding .005 to our difference). You will then need to flycut the tableboard with the program generated. You can now measure the thickness of your wasteboard. Go to the flycut routine under the wasteboard area and choose "set new wasteboard". Type in the thickness of your wasteboard. Under amoount to remove, choose .005 to .01 depending on how much you want to take off. Flycut the wasteboard with the generated file. You should now be set!!

Thanks Dan, that fixed it, I'm back to a .005 cut through and all dados and tenons are perfect. The problem was in the switchspoil value being off, I measured all 12 bits 3 times and none varied no more than .002.
