The schematic is very traditional and efficient.

motir My 10 ohm resistor is always get to smoke because of excess heat. The time now is This ic can provide a higher current upto 5A therefore it is possible the use of bigger motors or, using the same motors, obtain a reduction of the heat generated.

I have fixed the problem now but it still won’t run. Since i can’t find anything wierd on the board, i’m asking if anyone can spot any errors in the schematic or board layout, i have checked the board about 10 times for solder bridges or stuff like that so steppsr don’t think that’s the problem.

The max level of voltage can mohor considered around 40V. Product is in volume production 3. Originally Posted by MagooT.

The VRef must be regulated according to this simple formula: I have measured about every pin using my oscilloscope but the only strange thing i found is that the outputs of the L’s pin 1 and pin 3 are high all the time, when i step it slowly using jog in Mach3 i can see some small flickering around volt, but i assume it should switch between high and low.
