Bikin CNC Pen Plotter Pake Sistem CoreXY | HBot CoreXY Pen Plotter

(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 [e-mail] tapi harap maklum file nya agak berantakan karena statusnya experimental
