(Howto make this CNC Pen Plotter: at 4:50)
Proses perakitan CNC pen plotter menggunakan mekanisme coreXY. Sistem corexy memiliki kelebihan terutama pada kecepatan manuver dan konsistensi gerakan. Dalam video ini sistem corexy yang diimplementasikan adalah corexy tipe HBot

yg berminat file FreeCAD nya silahkan email aja ke romzi.ir@gmail.com tapi harap maklum file nya agak berantakan karena statusnya experimental

GRBL Parameter Setting:
$100 = 80.000    (X-axis travel resolution, step/mm)
$101 = 80.000    (Y-axis travel resolution, step/mm)
$102 = 120.000    (Z-axis travel resolution, step/mm)
$110 = 30000.000    (X-axis maximum rate, mm/min)
$111 = 30000.000    (Y-axis maximum rate, mm/min)
$112 = 15000.000    (Z-axis maximum rate, mm/min)
$120 = 2500.000    (X-axis acceleration, mm/sec^2)
$121 = 2500.000    (Y-axis acceleration, mm/sec^2)
$122 = 2000.000    (Z-axis acceleration, mm/sec^2)
remaining parameters are left default

Software Application: GRBL Plotter version 1.6.6.5 (https://github.com/svenhb/GRBL-Plotter)
