PoKeys / Momentary switches

« on: July 22, 2009, 01:30:40 PM »

Can you use Momentary pushbutton switches to simulate keystrokes? Or does it need to be a maintained switch like a toggle?

check out www.speedymetals.com

It is kind of hard to find within the site, so click on aluminum then plate, and its under there.

Well i have the G540 and like many others, I was having problems losing steps in the Z axis. I've read that using sherline mode fixes this, which it did. Now from my understanding all sherline mode does is increase the pulse width to 40micro.

Anyway, as for the rough radius, I think it was just the material i was cutting (cast tool and jig plate) because i ran some normal 6061 Aluminum last night and the radi's look fine.  Its a mystery

well obviously it has backlash but i have backlash comp on. Its less then .0002 on each axis.

.010 finish cut, climb milling.

I built my own CNC mill which works great. My only concern is that when i cut a radius, it leaves a "choppy" finish on the material. Is there any way i can smooth this out? Possibly something i can set with Mach3. Thanks

My setup is Gecko G540, Keling 48v PS, Keling 270oz motors, etc..
