Machine Builder Axis Direction

greglwood — Fri, 28 Jan 2022 04:30:24 GMT

I am attempting to create a new machine with machine builder including model. In my model the X, Y and Z axis works correction with the linear direction and constraints. However when I go into machine builders preview machine movements the X and Y are fine but Z's direction appears to be reversed. I can't find any settings in machine builder to correct this. I also looked at my post ( which I modified to add simulation) but it seems to get any setting form the machine library.

I'm not sure how to share this and I've never done a screencast before not know what software is necessary. I am including a link to my shared model but not sure if the machine builder stuff will come across with it so I am attaching my machine and post.

Ok, I figured out the screencast.

Hi @greglwood

The axis orentation is from the part attachment point (Head move up will be max and Head move down side will be min) so you have to change the max min the Z direction and i have noticed in your screen cast you are moving the joint in the machine builder this causes the Z axis will be repositioned and it will make that last place as the Z0 position.
I have attached a modified F3d file take a look into it

This works and correct my problem but it does seem inconsistent with the way joint limits work. You appeared to have removed my joint limits form the modified version you sent back. I left my in a it still works but again they work completely backwards which in my mind is inconsistent.

Thanks

Joints limits don't have relationship with the machine builder limits. Whatever you are using in the joint limits it stays in the design environment it doesn't interfere with the machine builder.

The machine builder uses the Z axis as always perpendicular to the table surface and the direction is always up to the table.

the reason i have removed the joints is i have made a export copy of the model to force reset the things you have used in the machine builder.
