Hello
This is my first attempt to make my own stepper board, with opto inputs, and only one voltage source ,a 14.6Amp meanwell regulated power supply
I have other boards, much more basic but all working about 24volts, I'm trying to go up to 44v with this one
I would like suggestions about the schematic and the board and I do not have much knowledge about design, all suggestions are welcome
Modifications I have made :
I have diodes after the snuber RC network SB560, 5amps schottky 60volts
Resistors RL2 EN and RL2 EN are intended to prevent the L6203 being powered without voltage in the logic
The Hex inverter is used to reverse the reversed logic of the 6n137 (NOT * NOT)
Voltage regulators are :
from 44v to 20v TL783
from 20v to 5v LM317T
The board will be single face and all the connections with RED color, will be made of wire.
In the design the L297 is not connected to the L6203 logic, it will be made with wires
