Thanks Mark. Every other place I hit wants to sell it in 100' or 300' rolls. But Jameco was a bit proud for the male IDC connectors, made up for the most part by USPS shipping. $29 for enough stuff to make 2 cables, with some ribbon left over seems a bit much. But they are ordered, hold for complete shipment mode. I managed to get the LM317T's mounted & wired, but the si rubber insulators I stripped out of a defunct Antec PSU aren't that good, the LM317T feeding a PSU fan about 17 volts measures 097F on the 317's tab, but only 71F on the other side of the 1/4" alu plate its bolted to, in a 68F room. With no drivers hooked up yet, it takes about 20 seconds for the fan to start slowing down, and another 20 secs to stop after I toggle the power switch back off. The filter is a pi section with an unknown choke inductance & 20k uf on both sides of the choke. That particular fan apparently has a poorly timed commutation, it looks like it's trying to crowbar the supply for about 200ns every time it commutes to the next coil sequence. I may see if there is a smallish choke in that PSU that will shove that stuff back into the fan, it might reduce the draw by a few percentage points. Silly Q about lathe mode. Can somebody load examples/lathe_pawn.ngc into their machine & see if its upside down and reversed left right on your display. Here it shows the pawn's radius above the centerline, and the large diameter bottom on the right. And will not of course run unless I edit the ini and let it go inches or feet negative in both directions.
