That sensor is a NC NPN sensor. It works by always grounding the signal wire until it's tripped, in which case the circuit opens and the signal wire should be pulled high by a pull up resistor. It...

Hi everyone! Do you know a motor stepper controlled like L297? This IC have only full and half step modes, but I would find an IC with a minimum of 1/8 steps. Can you help me?
View ArticleRe: Motor stepper controlled
I am not sure what you are looking for. The L 297 is a controller to drive a chip such as the L298 to drive a stepper. Are you looking for a chip to control an L298 or are you looking for a stepper...

My idea is to realize a simple board to control the 3D printer. About microcontroller I would use Arduino Mega. With this, can I drive L298? Also I would use a dip package like the L297. Is it possible?

Aren't there recently motor stepper controller that use DIP package?
View ArticleRe: Motor stepper controlled
probably not. Dip wasn’t really designed for lots of heat or current. also with the thermal stresses of heating up and cooling down it would wiggle out of a dip socket
