While cutting circles , A axis starts to move weirdly sometimes #271

Closed yagizzha closed 2 years ago

yagizzha commented 2 years ago

During this cut (its supposed to be a circle , because it was for testing calibrations werent done perfectly) it does a weird clicky-ish sound while cutting , not going smoothly https://user-images.githubusercontent.com/88779645/160825346-6bc63b26-6850-455f-a2a6-b6f6b6166ec8.mp4 Gcode for that one looks like this : 5ca0651b-0d3e-4312-8cfb-7599a2a5b4ad However , another circle from same file works fine (again dont mind the paper moving , its just to show the movement): https://user-images.githubusercontent.com/88779645/160825636-6576d7fd-1b55-4dbb-b293-2c764c4f0477.mp4 GCode for that one is e111ae63-737f-4af8-9ff5-6c72e71d0a68 Is this a bug or some feature we are missing ? if a feature how to work around so it cuts smoothly aswell

svenhb commented 2 years ago

You need to increase this value: If angle between two lines is too big (bigger than this value), the start angle for the second line will be adapted. image

Same issue happened while doing it with ellipses , increasing start angle didnt help

svenhb commented 2 years ago

Please send graphic, gcode.result and expected behavior

If I copy & paste your GCode I see the same edges in the 2D-view, as in your picture: image

You should adapt this parameters: image

Then curve is less angular: image
