Hi all, it has been a minute since I’ve used the CNC and want to do something with it that I haven’t before.
Thanks in advance!
The dog holes will be your friends in getting the alignment right. Note that the machine coordinates of the front left corner defined by the dog holes is posted either on the main power box or on the controller itself. To set your origin at that corner, home the machine, zero X and Y, move to those coordinates, then zero X and Y again.
Thanks! That was helpful.
Do you know of any dxf files (or Fusion) for the dog holes? I’ve found a few threads on this but no files.
I did a test run yesterday and my alignment wasn’t as accurate as I would have liked. I want to try cutting out circles in my squared board to match the dog hole pattern/dogs.
It is also possible that my stock got misaligned and via a hiccup with my bit but figure matching exactly to a the dogs would be more consistent.
I am interested in the best solution to this as well. I will be doing some multipart epoxy carves/pours and will need to ensure correct alignment over a multi day period.
Also of value to me would be to get a copy of the 3D printed alignment pegs designs that fit into the dog holes. This way I could print my own and ensure I am always using the exact same alignment pegs each day.
I created the STL file for the bench dogs (smiley face red & black ones) that I’ve been donating to both CNCs. They are printed in PETG on their side, .20 layer height, and 50% infill. Send me an email at bwatt@1fifoto.com, and I’ll send the file to you, because I can’t attach it to this post. Or just tell me how many you want and I’ll print you a set (I have a 3D printer at home).
The dogs are useful but if you need precision dowels are a better option. If you do use the dogs make sure you use the same reference edges of the stock. That means you’ll use dogs on both sides of the bed.
P.S. I would recommend dowels too. I just responded to your request for the bench dogs, because you asked for them specifically.
