Alignment Of Sheet on Cut Bed

Team i am definitely putting the cart before the horse here, as i haven’t finished building yet.
So I have a lot to learn before i even get cutting.

But, I am wondering, Do you guys have orientation/alignment markers on each axis to make sure the cutting material is always in the exact same position.

As soon as i am setup, I have a to cut about 20 sheets, all exact LxW, and exact same cutout on each.

Ive watched example videos where the sheet is just laid down and the cutouts are made, but i need the “negative” as such is the piece im keeping so needs to be perfect on each piece.

I hope that makes sense.

Hey, welcome to the community, I’m pretty new here too.

I think what you are talking about can be achieved with spoil board squaring.

I’ve been googling a bit about it myself.

Some of the guys her have done some fancy stuff with their spoilboards. I’m planning on building a parametric table, and then hopefully a fancy spoilboard too.

Ive almost done my printing, so hopefully I’m not far away :slight_smile:

Assuming the start position is the same and the piece you place down is always the same it shouldn’t be a problem with the same program.

For me whenever I’m doing something similar I have the 0,0butted up against a fence I screw down into the spoil board, knowing it’s flush against that should equal same size cut on the piece

What I use is a big (400mm x 400mm) L shape in the bottom left corner of the table with a circle removed from the inside corner.

Get that squared up and set so where the lines meet is 0,0 and you can use it as a bumper to push your pieces up against.

You can see what I mean in this picture - this this case I’m also using spacers - cutting so close to the edge of the metal I was worried about the collet hitting it.

But as long as you know the width of the spacers it’s easy to account for them.

Yes, xmin and y min have a 15mm pvc stripe bolted down then machined 4mm away from the spoilboard. Then i place some 4mm acm strips to place down whatever im working with.
