Drawing Speed Variation

[flux]

How can I set drawing speed on a line / line segment granularity? Is this possible through a vector graphic or would I have to use the api?

Goal is to accomplish thinner lines with faster drawing speed.

Thank you!

There is not natively support for per-object drawing speed variations, but you can probably work around that by using the layer-based controls. You can find documentation for them here: http://wiki.evilmadscientist.com/AxiDraw_Layer_Control

To use this method, select all of the objects that you would like to plot at the same speed, and move them to a layer that is set to print at a given speed.

Alternately, if you’re coding this, feel free to give each and every line segment its own layer. However, be aware that there will always be a pen-lift operation when switching between layers.

If consistently controlled line width is your goal with different speeds, you’ll likely also want to use the constant-speed method, as otherwise there will be acceleration on pen-down strokes.

Thank you very much for the quick reply! This should work nicely for a first test run.

The ultimate goal here is to draw continues lines with variable speed without lifting the pen. If I understand you correctly I will have to go low level to accomplish this.

Edit: Just looked at the restful api, but couldn’t find anything useful there? Am I missing something? Do I have to go lower and write my own driver?

This looks very promising: http://axibot.readthedocs.io/en/latest/

If you want to vary the speed within a stroke, then yes, you’ll need to use a low-level interface of one type or another. You can either use the direct serial interface (EBB commands), the [robopaint API](https://github.com/evil-mad/robopaint-mode-remote/blob/master/API.md “robopaint API”), or other means to do so. If you can say what tools or environment you are using to generate your vectors, I might be more able to point you in the right directions.
