I have seen a lot of pen mods out there for the A1 and mini, but only g-code for the mini(Thanks to leonllrmc and his awesome work, you should check out his project). I decided to make my own g-code for the A1. I put a lot of effort into making this project so please consider leaving a boost. 

If I have left anything out, or you have any questions, feel free to contact me.

For those of you wondering if you can use this to synthesize handwriting for a school project, I found a cool free website that you can use to turn text into handwriting. In the top right corner of the website there is an option to find a handwriting style that looks like yours. This website also exports as an SVG file so there is no conversion needed. The website is found here: calligrapher.ai

Soon I will be uploading an instruction manual, so please be patient, and contact me with any questions.

Delete all Start and End G-Code and replace it with this:

Start G-Code:

; ===== Plotter Start G-code =====
M104 S0 ; Set nozzle temperature to 0 and don't wait
M140 S0 ; Set bed temperature to 0 and don't wait
G90 ; Use absolute coordinates
M17 ; Enable motors
G28 ; Home all axes (X, Y, and Z)
G1 Z10 F3000 ; Lift pen 10mm for safety
G1 X0 Y0 F18000 ; Move to front-left corner
M400 ; Wait for all moves to finish
; ================================

End G-Code:

; ===== Plotter End G-code =====

G91 ; Set to relative positioning

G1 Z10 F600 ; Lift pen 10mm away from the paper

G90 ; Return to absolute positioning

G1 X0 Y250 F18000 ; Move head to side and push bed fully forward

M104 S0 ; Ensure nozzle heater is off

M140 S0 ; Ensure bed heater is off
