Framing not working correctly in rotary mode

Hi,

I’m trying to use a x-axis with galvo laser.
I know the feature is not officially supported now, but by using rotary mode and some math(circumference and steps calculated for each engraving), it’s possible to have planar surface engraved instead of a cylinder.

But the framing, inside rotary window, seems not to work for slice out of engraving area. And the slice inside engraving area is not accurate. When I frame directly in normal mode, without rotary window (first framing in video), the framing is ok.
I tried with shape out of bonds, cut selected, all different options, I’m getting same results.
I used red contour vector for framing, bitmap is not set to output.
It make rotary mode on planar surface totally unusable for precise engraving.

It would be great to have a real linear axis mode with slicing for bitmap or vectors.
Almost everything seems coded, just not accessible the right way :slight_smile:

What happens if you actually try to burn the image? I’m not sure I have had 100% success with framing slice advance when image is way off the work area. Figured I would mess around with it a little more before I complained. I assume you have “Ignore Out of Bounds…” disabled? I have had success doing exactly what you are doing with a smaller X table I built for prototyping and concept but LB didn’t have framing slice advance at the time. Still worked as a flat rotary as expected.
Let me ask you a question, the table top you have there, where did you get it? I have an XY table, mostly complete, 800x240 travel but can’t find a deal on the main table for less then an arm and a leg. the one you have there looks like exactly what I am looking for.

Hi,

The engraving itself is fine, when good circumference, steps and overlap is dialed in.
It works for pictures on large surface, i use first slice frame to align on left border.

But in the video, it’s a job to be done on a pizza cutter, where position of the black marking on stainless steel must be very accurate. It’s not a simple rectangle surface, as showed in video. It would be great to be able to frame every slice on the pizza cutter.

The top aluminium profile is from Aliexpress.

There is 3 different dimensions: 310, 625(mine, model B), 930mm
Total price with shipping to Belgium was 125€ for model B.
It’s flat, good quality and well packed, i recommend.

Build your table yourself?

Yes there is a linear axis using two mgn9 and sfu1605. Motor Nema24.
And some 3D printed parts.

So just ran a test on the rotary, 13 slices and it rotated to each on and framed them, using the frame on the last window, maybe that’s where you are off? Not the first framing option
Not the live framing window:

This window, Rotary Marking Frame:

Hi,

Many thanks for your advices.
Yes i have only the problem with the “frame” button in the rotary window.
I’m using RC4 version, i will try again with a new project, and tell you if i have same problems :slight_smile:

Best regards
