Re: [CAD_CAM_EDM_DRO] Re: Bipolar Stepper series vs paralell wiring

Phil,
 
Crashes?   I never have crashes!  Yah right.......   
 
Well, I guess I can say I have only had a few crashes with the mill and router I have.  Never broke a machine from crashing knock on wood.   I use both limit switches and soft limits on the router and soft limits only on the mill.   I usually use Rhinocam for tool paths and the simulation helps to eliminate obvious problems. 
 
One day I started a long program,  we're talking a couple of hours of machining.   I was new to limit switches and soft limits.   The machine kept stopping after only a few minutes each time I started the machine.   I couldn't figure it out.  Then I sat and watched the machine until I watched it run out of Z and trip the soft limits.   Talk about feeling stupid!
 
Back to the fun....
 
Jack

I concur. I had a Sherline with the same motors running on a 24v power
supply and it had plenty of power for the Sherline. Could have had more if I
had spent more on the drivers, but even at 24v you have enough torque to
break the machine in a bad crash. (We avoid bad crashes by being careful.) I
don't think you'll be disappointed.
