"Best" is a subjective term, especially when it comes to CAD, so you will probably get lots of opinions. I've using Alibre Design for a couple of years for 3-D part and assembly design and have been

Does anyone have any opinions on what is the best CAD software for a CNC milling machine? I am building a 3 axis gantry type machine driven by steppers. The motors will be controlled by Pic List

A little late coming into this discussion, but just one more thing to consider -- when the motors are holding their position, is one winding energized, or both? If you have 1.4A flowing through one

This is a really old thread, but I am just catching up on my email and wanted to add my 2c, for the record: The one advantage of L297/L298 solution is that you can chain several L298 chips in

I didn't think you were being dismissive, it's usually hard to get your head around something new. A new idea either replaces something existing, or creates a new market (and sometimes then wipes out

There are quantization problems with other than simple CAD models, however. Curves and low-tangent cuts are particularly subject to quantization error effects -- think of "jaggies" in graphics

I'm still getting my MP1000 Torch Height Control set up from CandCNC.com but now that I've got a Hypertherm 1000, I'm getting great cuts cutting out 5/16" holes, 3/8" square holes, etc.. I have not

of my locomotive mill cool. Ron, you can do some nice detail with the smaller plasma units like the Hypertherm 600. If you can justify the cost you can step up to the Hypertherm 1000 and use Fine Cut

For years Ive wanted a laser to cut parts for model engines, but to cut metal I realize the laser power is too high and the prices way out of my range. But maybe a plasma cutter could do it- are
