+====== DRAWBOT ======
+there are three repos needed to get this going
+  * GRBL [[https://git.telavivmakers.space/yair/grbl|git]] - the firmware running on the arduino+grbl shield
+  * drawbot_LY [[https://git.telavivmakers.space/yair/drawbot_LY|git]] - the Inkscape extension that converts vector to gcode
+  * Universal gcode sender- this [[https://universalgcodesender.com/|java app]] loads the gcode above and sends the gcode commands one by one to the Arduino over serial.
+the above fork of GRBL has been adapted to make servo handling easier (check commits). \\
+there are also EEPROM kept states that need to be adapted to our machine. \\
+  - enabling of homing sequence (the [[https://he.aliexpress.com/item/1005005888174412.html|machine]] did not come with limit switches)
+  - adapting the number of steps per millimeter for x/y
+  - keeping steppers motorized ''$1=255'' (thanks paul)
+the drawbot Inkscape extension also got some love, with a few fixes. notably, disregarding hidden layers, addition of x/y offset control.

-To draw a Rubik's Cube in an isometric view, you will need a series of G-code commands that move the pen in a specific pattern to represent the cube's edges and faces. The Rubik's Cube consists of 27 smaller cubes arranged in a 3x3x3 grid. Here is an extended G-code example to create an isometric view of a Rubik's Cube, starting in the upper left.
-This code assumes that you'll be using a pen plotter or similar device and will draw on a 2D plane that represents the cube in isometric perspective.
-```gcode
-G21 ; Set units to millimeters
-G90 ; Set to absolute positioning
-M5 ; Pen up
-G4 P1 ; Wait 1 second after pen up
-M3 S1000 ; Pen down
-G0 F2200 ; Set movement speed
-; Move to start position for the isometric view
-G0 X40 Y40 ; Move to the starting point
-; Draw the front face of the Rubik's Cube
-G1 X60 Y60 ; Move to front right corner
-G1 X40 Y80 ; Move to top left corner
-G1 X20 Y60 ; Move to front left corner
-G1 X20 Y40 ; Move to bottom left corner
-G1 X40 Y20 ; Move to bottom right corner
-G1 X60 Y40 ; Move to front right corner
-G1 X40 Y40 ; Move to starting point
-; Draw the middle layer of the Rubik's Cube (slightly above the first face)
-G0 X50 Y50 ; Move to the middle layer starting point
-G1 X70 Y70 ; Move to front right corner
-G1 X50 Y90 ; Move to top left corner
-G1 X30 Y70 ; Move to front left corner
-G1 X30 Y50 ; Move to bottom left corner
-G1 X50 Y30 ; Move to bottom right corner
-G1 X70 Y50 ; Move to front right corner
-G1 X50 Y50 ; Move to starting point
-; Draw the back face of the Rubik's Cube (further back)
-G0 X60 Y60 ; Move to the back face starting position
-G1 X80 Y80 ; Move to back right corner
-G1 X60 Y100 ; Move to top right corner
-G1 X40 Y80 ; Move to back left corner
-G1 X40 Y60 ; Move to bottom left corner
-G1 X60 Y40 ; Move to bottom right corner
-G1 X80 Y60 ; Move to back right corner
-G1 X60 Y60 ; Move to starting point
-; Draw the edges connecting layers (create depth effect)
-G1 X50 Y50 ; Move to middle layer starting point
-G1 X40 Y40 ; Draw edge to bottom layer
-G1 X40 Y80 ; Draw edge to top layer
-G1 X30 Y50 ; Draw edge to furthest left layer
-G1 X50 Y50 ; Return to middle layer starting point
-G1 X60 Y60 ; Draw edge to back layer
-G1 X45 Y55 ; Draw slightly towards the bottom right to create depth
-M5 ; Pen up again to end drawing
-G4 P1 ; Wait 1 second after pen up

-### Notes:
-. The coordinates (`X`, `Y`) should be adjusted based on the actual size of your drawing area and the desired size of the Rubik's Cube.
-. This code assumes a basic movement sequence and will plot an isometric view of the cube, but it may require further refinement or more details depending on your exact plotting capabilities and requirements.
-. Adjust the `G0` and `G1` speeds according to your plotter's performance and necessary drawing speed for better clarity.
-. The colors of different squares cannot be represented in G-code directly; thus, this drawing is simplified. Additional coding would be needed if you were using different pen colors to represent different cube colors.
