Re: Past items????
Bill, It wouldn't be welcomed by those already using Stepster only. There are people out there that already have Stepster working and wired up, this should not involve them in having to change their

Re: Past items????
Bill, I'm working on Stepster in my free time. (what little I have) - I know how to get the limit switch working, and I'm going to put it into test SOON (I wanted to do it 2 weeks ago). It's just

Re: Newbee, Laser Machining Anyone?
I just subscribed to this list. I built a 2ft x2ft 3 axix desktop router/CNC machine a few years back when not much info was published. I am using a 3 axix 2 amp controller from Camtronics Inc,

Re: EMC C Code
The Java program did not do real time machine control. There is a vast difference between being able to compile code on a platform and actually being able to execute it. With some work, you could

Past items????
Not too long ago there was some comments about upgrading one of the smaller CAM programs, I think it was Kevin Carols CNC981 if my memory is correct. I was wondering about the status of the work on

Re: Machine geometry
Gar, The 4 by 4 was built using Item aluminum extrusions. The X and Y rails were Ina bearings on 14mm shafting (top and bottom). The Z axis uses THK bearings with about 6 inches of travel. In

Re: 10 amps to drive steppers
Let me chime in. On some units that I sold to people that live in very hot climates like india, I included some thermal cutoff switches. I simply mounted one rated at 135F on each heatsink. I wired

Re: 10 amps to drive steppers
The kit contains some really nice but large heatsinks. I don't like to run mosfets much over 130F with heatsinks on them. One of my customers has one of the few units that I sold as complete units. It

Re: Servo motor question

Re: EMC C Code
Thanks My misunderstanding as to the real meaning of "code portability of C and C++". JAVA version would be a platform independent software maybe but still need a RT OS???

Re: 10 amps to drive steppers
No, the FETs themselves are too small to radiate much RF. The traces connected to them, however, are large enough to radiate. You have to minimize the area inside the loop of the current paths.
