Tweakie:
In my imaginings, I had planned on drilling a small hole in a peltier element I have here. They are semiconductor slabs really so
drilling a hole shouldnt hurt them. then if the gantry pulled the peltier along while burning the glass though the peltier, I might
be able to get a very large thermal gradient. Ive never gotten to test that theory yet,
but I have a 2" square peltier laying here.... someday soon maybe. Im think at that point motion speed is then a gradient control
instead of just heat control, it also would give me a pot to turn to increase gradient or lower it. ( Things always work better when you have
a pot to turn.. lol )..seriously though .. a peltier with a hole in it could give a very large gradient , these things get very very cold when you have an
appropriate heat sing and fan on them, and it should be possible to right through a hole in the heatsink and a hole in the peltier.. I think
dragging one across glass may work...
