The Universal Carrier Base

[Underdog]

So if the optical sensors are finding all the edges of the board, then why does the bit do the "bob" thing?

Oh. It's finding the board thickness? I suppose it knows where the zero point is already? I haven't watched my machine very much, and it's been a while anyway...

Yes, it bobs as part of the thickness determination. The bob at the brass roller is to get an idea as to the depth to expect for the sliding plate when it bobs for it. The difference between the touch on the board and the touch on the sliding plate determines the thickness.

Thanks Berg! Much appreciated. Hopefully I'll cut something out tonight.

The machine will just bob three times trying to touch the right block (sliding plate) and then ask for the board thickness.)

Hi B. long time user(09). bought new c machine in july. Made a sled so as to use .500 stock. no problem. Made a sled for .750 stock. Problem is, the three bobs generate the following...Retry or Cancel. any thoughts before trying your universal sled.

Tell us more about the dimensions of your sled - rail width, base thickness, etc. Also, what is the entire message that is being displayed?

Problem is, the three bobs generate the following...Retry or Cancel. any thoughts before trying your universal sled.

If the machine touches at the brass roller and cannot make the touch at the sliding plate you get the Retry or Cancel. (The sliding plate touch is higher than the brass roller touch and so the programmer figured that the only thing which can be occurring is that the user has not moved the sliding plate up to the board.)

If it cannot not touch at the brass roller, the programmer figures the board or sled is more than 1" thick and asks for the thickness. (Why it bobs three times anyway at the sliding plate is a mystery to me.)

If you are using the UCB, make sure the right block is higher than the left block. (Or just take both blocks off.)

Base = 13.75y, 19.0x, .75z
Rails = 1.25y, 19.0x, .75z
Front/back blocks = 9.0y, 4.0x, .75z
Base + rails = 13.75y, 19.0x, 1.5z
Base + F/B blocks = 13.75y, 19.0x, 1.5z
The partial massage is from Bergerud post #240

So now that I have this made, the question is how do I do 2 sided carving? several of my patterns have a keyhole on the reverse side for hanging and Im wondering how to accomplish that.
Thanks

[Dale]

I could be wrong but I do not think you can. I just make the key hole a separate pattern.

See post 103 on page 11, I don't recall anything further saying that it wasn't possible.
