First post here! Has been useful just lurking so far though. Looks like an excellent community and I can see myself spending a lot more time on this site
I recently purchased a 3-axis router (no motors, spindle or electronics) and I'm trying to work out what I should get for the power supply. I need 48V at a little over 10A. So I have the choice of going the linear route, using a toroidal transformer, bridge rectifier and caps (although this looks nice, can anyone comment?)
Or I can get a switch mode supply (which might work out cheaper seeing as a guy at work might have a suitable one for me for free). I haven't found much about using SMPSs for stepper motors and stepper motor drives (I'm planning on using gecko G201s) but I did see one thing (can't remember where) about possible issues with them because of the nature of motors and back EMF (IIRC).
I was wondering if anyone could tell me the pros and cons of both types of power supplies when used for steppers and stepper drives, or indeed if SMPSs are just not suitable and I should go with a linear supply?
