I l66203 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.

Hello dudes, i have assembled a board using this schematic http: When i measure between GND and motor outputs M1-M4 i just see a blinking line at 10 volts on the oscilloscope. It employs two integrated L that each pilot phase and a L which is responsible for the translation of step and implements the chopper.

I have fixed the problem now but it still won’t run. Nothing more to say, the schematic is very traditional and follows the directives of the application notes of the ic involved.

The current minimum payable is approximately mA and with this range of current deck covers all the needs of cnc amateur pilot and industrial. The max level of voltage can be considered around 40V. Guess it’s time to etch a new board an try it out.

Because the chopper isn’t lowering the current at all, can anybody explain how to do this? I even built a whole cnc funzionante.

I found one error 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. Another question, i’m trying to run a small motor from a printer don’t have any other specifications for it other than “10 ohms”, unfortunatleyand it get REALLY hot just after a few seconds, so i assume i must recalculate sense-resistors or something?

My 10 ohm resistor is always get to smoke because of excess heat.

Problems with stepper driver L and L Since i can’t find anything wierd on the board, i’m asking if anyone can spot any errors in the 2l97 or board layout, i have checked the board about 10 times for solder bridges or stuff like that so i don’t think that’s the problem. Thanks for your help.

On the l66203 of the bridge is a trimmer and next to it a measure called Vref. This is necessary because the maximum input tension level is limited to 20V for a 78L05 and V for a 78H05 but usually less and depends by the manifacturer.
