Hi.
I would appreciate some comments and thoughts on the following circuit. It is a bi polar step motor controller based on L297 and L298 ICs.
I'm planning on using an ATX computer supply, jumpstarted and with a dummy load. 12vdc 21w car brake light bulb.
In the shematic the diodes are 1N4004, because I couldn't find the ones I have. That is SBYV27-50.
The POT is 10K.
JP1: ATX powersupply
JP2: Half step and full step selection
JP3: 12V 3A 1.8° NEMA 23
JP4: Step and direction pins
I've used, or at least tried to use, the schematic from the datasheets.
The L298 will have a heatsink with a 12v fan.
Thanks for reading.
