When using rotary image is inverted in Y axis

[Ram48 (Raymond A McCrodden)]

Small problem, I am most likely overlooking something but when using my rotary the image looks correct in the camera overlay but engraves in reverse in the Y axis. I can correct by mirroring in that axis but Id like to figure out what I am missing or what setting I my need to change. LB 8 mp cam ruida controller and all specs listed in bio. The rotary is a three wire chuck type

You may need to flip your rotary 180° on the bed (or rewire the rotary’s motor). I elected to rewire my rotary’s motor because I preferred the orientation on my rotary the way it was.

Jeff the image is mirrored front to back on the Y axis I may be missing something but turning the rotary 180 would change the X axis would it not? The Route 66 is the image
I have a three wire rotary will swapping two of the three wires work?

@Ram48,

Let me illustrate:

Here I have a job set up to apply to the rotary. Some side notes - I have Rotary enabled, I set my job origin to top center (with respect to the artwork making it easier to position on my object in the machine), and to start from current position.

The way I prefer my rotary orientation is pictured here (and as such I created my design to this same orientation)

The resulting work comes out as expected (no mirroring).

If I prefer my Rotary to be turned the other way in the machine:

Then I would think to make my design like this, right:

But, because my stepper motor controlling the Y axis is wired opposite, I would get a mirror on Y:

The Y mirror is exactly what I am getting with my chuck set on the left side, (just like it was on my other Bodor) I guess I will either need to set it up on the right or figure out how to wire it to work correctly from the left side. Is there a way to do that with a three wire rotary? I found how to with a four wire but that is of no help to me.
Thanks for the visual on the rotary, my way of thinking about it would not let me work through that

Hey, I know what you are going through. Trust me because I was in your shoes, so I am happy to help the next person. I too have a three wire / three phase stepper. I think these posts will help you:

3 Wire / 3 Phase Stepper in my Rotary Needs to be Reversed

Please, can someone help me understand what I’m looking at? I set out to reverse the coil pairs on my rotary and was confronted with a very strange surprise. My 2 phase stepper motor only has three wires coming out of it. I scratch my head and search everywhere trying to figure out the right way to reverse the direction / wiring. I’ve applied a volt meter to the pins. I’ve read resistance. I’ve read voltage (while turning the chuck). No matter what two pins I measure, values are always the s…

When Using Rotary, Must I Always Rotate 90 and Mirror?

So, when I work on my projects normally (when not using the Rotary), the orientation of the design as well as the output at the laser is fine (and matches). But for over a year, when I do Rotary work I always have just rotated the design -90 degrees and then mirrored it so it would output properly to the object on the rotary. For example, if I created this (normal orientation): [image] The result on the Rotary is this (90 degrees wrong / mirrored): The Controller shows: [image] The outpu…

Change of direction

I got a new rotary, before the new one the laser alway printed left to right on the rotary. The new one is printing right to left. Where do I change this, I’m not in the mood to have to remember to swap used files around before running them. Thanks
