Just got this through from a member: "Since the heat (energy) is not used for cutting, but for overcoming the latent heat of fusion of the foam, all of your observations are right on the mark. I'd

The motor itself should be ideal. Mechanically it should be pretty much a drop in replacement. A Gecko drive will have problems with the 2000 count encoder. Apart from the speed issues Jon mentioned,

Will the servos on http://ajaxcnc.com/cnc_components.htm work well? If I understand right the 29 in-lb would be the right size. Maybe the 40s on the x and y when I get to

Does EMC only handle trajectory planning in XYZ Cartesian coordinates, or does it also handle G-code interpretation and motion planning for 5 or 6 axes? -- Carl

Hi Nathan, I went the cheapskate route and bought some treadmill motors from Surplus Center. They were similar to these:

I haven't done any rigorous experiments, but observation suggests that the temperature of the wire is lower inside the cut than outside in the case where the material is thinner than the length of the

I'm usually a lurker, but I'll chime in on this topic. I've built three cnc foam cutters (before that manual systems). Factors at play: foam density(some crappy foam changes density within itself,

As other people in the group the current to give the proper cut vary with the foam density and also with the speed of the cutting so I use to determine it experimentally. I use a 12v / 24v

I had exactly the same problems as you. On top of lost steps I had problems with the Z drive blowing. In the end I changed over to servos and now it performs brilliantly. Rapids are limited to about
