For example, if te step angle of the used stepper motor is 1.8 degrees the value is 200 steps.

Adjust Steps Per Rev according to the stepper motor type.

For example, if the belt is GT2 the lue is 2mm.

Set the MM Per Rev value according to the pulley and belt you are using.

Stepper motor and pulley settings (in Polargraph)

Secondly click Center Home Point and set Home Pos Y value 120.

Then, first clicthe Center Page and then set the Page Pos Y value 120.

(If ou will draw on an A4 paper, set the A4 size.)

After machine dimensions, adjust the size the area you will draw.

Adjust the Machine Height (height between the pulleyand the end of the panel).

Adjust the size between two pulleys on the Machine Width.

Enter the Setup section from the tool bar.Run the program by pressing the Run button.Then open polargraphcontroller (file -> sketchbook -> polargraphcontroller) We will use these values in the software section.ĭefine first settings - Machine dimensions (in Polargraph) This is a magic point marked on the centerline, exactly 120mm (12cm) down from the top edge of your machine. This is the distance from the sprocket axis to bottom of your drawing (board) area. This is the distance between two closest points on the sprockets (between two pulleys). Your PAGE or drawing AREA size will be smaller.Remember that your machine size is NOT the same as your surface siz.A project collaboration and documentation platform.Membership connects and supports the people and projects that shape our future and supports the learning initiatives for the next generation of makers.
