My name is Yousif , I'm a 16 Y/O arduino lover .. well .. i've been watching this guide about ( CnC plotter device ) , and thanks to ardumotive_com https://www.instructables.com/id/Mini-CNC-Plotter-A... ,, TBH I'm not a perfect arduino programmer , i know a lot of things but it could never be enough about arduino .. So im making the same device . Here I'm trying to make my own changes to the devices .. I almost completed the device , then i stopped making it cuz i have some trouble that stops me .. those are the changes that im gonna make and i need some hlep with'em :- i've changed the motors to 2.3Kg*cm Bipolar stepper motor .. http://www.zeroohm.ae/Actuators/Stepper-Motors/Ste... . The motor driver : Ardumotive_com used a L293D motor driver to control both of the motors , the question is : can i use it with this new motors ( look above ) ? , gonna need for an external power source with a new board ? , and how could i connect it to this chip without destroying the chip .. I'm gonna change the pen to a dramel with extender ( avoiding high weight and size ) , so i decided to use this tool .. https://www.desertcart.ae/products/1321441-dremel-... . I already have a lab power supplay with two wires( i mean red and black wires at the top , with adjustable voltage ( 12,14,16,18,20 ) ( thats all what i have ) .. how can i use it with the L293D chip ? At the end i could never do it without ardumotive_com , and please somenoe help me cuz i have less than a week to do it .. if u wanted anything about my device , u already can visit this link https://www.instructables.com/id/Mini-CNC-Plotter-A... , becuase i almost used the same .. and thanks !! , gonna be waiting !
