Tangential knife angle does not follow xy trajectory

[lm150617]

The tangential knife angle does not follow the xy trajectory of my path. The blade stays at a 0 degree angle.

Changes to the default setup:

File/Setup/Graphic imports/Path imports/Path modifications

1. Add Tangential Axis (Enabled)
2. Name of tangential axis (Z)
3. Swivel angle (30)
4. Correct start angle if deviation is > (5)
5. Units per turn (3.6)

File/Setup/Graphic imports/G-Code generation

1. Z axis (Disabled)
2. PWM(Enabled)
3. Pen Up (50)
4. Pend Down (500)

I expected the blade to rotate as it passes through the rounded edge, like in this demo: https://youtu.be/uMFyTCK8Ggw

This modification only works on graphics import. After import you see the applied modifications in the bottom line: I don't see this in your screenshot, but the headline shows you loaded a SVG file. With your settings, the code should look like this:

After the change of settings you may press this button to reload and apply:

Im using Inkscape. I made a path to look similar to the one on your Youtube video. I imported as an .svg file.

Did you read my edited comment? What do you see as import options in the bottom line after import?

[lm150617]

I see : [Import options: ]

[lm150617]

I see: [Import options:]

Can you upload your svg file?

[lm150617]

I tried but github error says "We don't support that file type"
Is a zip okay? test 1.zip

Are you sure your settings here are same?

[lm150617]

Yeah I checked it many times and tried to play aroud with the numbers and its the same every time.

The only way ive been able to make it work is doing a circle with a 90 degree cw transformation.

Your test1.svg works for me... What settings do have here:

I assume there is an additional modification activated, which is not listet in the bottom line... There should be no difference with this issue, but who knows... Try latest Version 1.6.0.5: https://github.com/svenhb/GRBL-Plotter/releases

Thank you for taking the time to look at my issue. I appreciate you!

Any success up to now?

[lm150617]

No, I've noticed that when I upload an svg the z axis stays at 0 unles its a circle. Also I don't see an up/down translation command at corners. Any idea why im not having success?

Perhaps it is solved, if your problem matches #270 or #272 New features
