Hi everybody,
Since this is my first post i would like to congratulate you on the wonderful forum that you have here and indeed it has a lot of info for everything and since a lot of people take the cnc machining as a hobby i decided to give it a try. Well i did some research and read few thing about cnc machines and in short they are not that difficult to build (if you buy all the parts of course, mainly the electronics). It seems that everything starts with the motor that you are going to use and in most cases is the NEMA32 stepper motor. I found this stepper motor http://www.kelinginc.net/KL23H286-20-8B.pdf the one that is bipolar parallel. Now on to the drivers. A couple of people here have a schematic using the TA8435H with a complete PCB design, but the TA8435H can produce only 2.5 A peak. Google Translate. Is there any way to replace the TA8435H with something that goes up to 3.0A since the stepper is 2.8A. Another question that i have is the voltage, what are the Vm and the X1-1 from the link??? Another schematic can be found here Oatley Electronics, but i can't build a PCB since i don't know how to read the schematic, or at least alter the first one to suit the stepper motor. Could somebody post a PCB design and it's parts so i can build one myself? Or at least guide me to a web page?
Thanks
