unable to plot circle using this firmware

[imkifel]

Hi, @Cpt-Hook
I tried to plot different shapes by passing gcode. I am able to draw shapes without circles.

when I try to draw a circle it's getting stuck at some point for a few seconds and it is losing its position and plotting the values somewhere else. is there any way to fix this?

The firmware of the ESP32 does not know how to handle circle gcode commands. I solved this by sending the gcode commands through my other project: https://github.com/Cpt-Hook/Gcode_sender
This app translates arcs into series of points that the ESP32 firmware can handle.

can you specify how you have done the conversion of the arc into a series of points, like can you specify the formulas for the conversion. it will be helpful. thankyou

sure, the logic is implemented here https://github.com/Cpt-Hook/Gcode_sender/blob/master/src/main/kotlin/gcode/ArcExpander.kt
