Hallo Abbe,
It looks very goed.
Greetings Dimitris.
Hello Abbe ,
Can you please tell me what interface did you use i see on the picture and i like to know can you send me some link where to find scheme ? and also please let me know are this driver work ? becosue i have build one driver from other schem and dont work
Please help me
Dear abbe,
Good job!
One thing that you may need to do is to make the heatsinking of the L298s a bit more substantial if you are putting a lot of current through them, even though you seem to be using a fan on the aluminium angle. Angle has a whole lot less capacity as a heatsink compared to finned , purpose-designed, products
Just a thought.
Best wishes,
Martin
Hi, if use a unbipolar stepper motor,
I suppose that L297+sla7026 will be a good combination,not only the current will be 3A,also the diode can be integration in the IC,which can save space.:rainfro:
All those SLA chips are very hard to find.
i tried for SLA7078 and 7062 for months.but failed.so i moved to Linistepper,which worked like charm.(still i liked SLA chips,as they are all in one controllers)
Hello to all
This is very simple L297/L298
Here is a board, schematic, and bom
http://pminmo.com/l297unipolar/l297unipolar.htm
L297+L298 combo is good.but it lack of micro stepping.and it makes the stepper hot too.i tried and build this combo already.but it didn't gave me as much satisfaction as linistepper did.
iam quite interested in SLA chips but as i said before they are almost impossible for me to find.is it possible to get some samples? can any one guide me here?
I bought SLA from Farnell
how much they charged? (each)
7 Euro
I am doing about Stepper but I am not understand. If Somebody have documents about it. Please share for me. Thanks, my mail:[email protected]

Thanks I read it now.
hi
i cant speak english well
i have a question
how much rpm did your driver has
hello.......... main poster of this post..i assembled the driver which you told about ..the problem is that = stepper motor is not going more then 150 RPM (200 steps per rev. motor)
plz plz help
