Can't buy that. Bill Nope, never fly. See if superglueing some heat sinks to them might help, and in my case, I have a pair of old psu fans running on about 18 volts to they really sing to you, one in each end of a box with the xylotex board in it, the box just fitting the outside dimensions of the fans, one blowing in one one end of the box, the other sucking out the other end, so I probably have a 20 mph breeze flowing across both sides of the pcb itself. I've had one fan fail in about 5 years, so if you start with decent computer psu pulls that claim to be ball bearing models, and it lasts 10 minutes at the higher voltage, it should last 5-10 years. I used 18 volts basically because that was the only lower tap I had on the motor psu I built from an old Ampex 2 videotape machine's drum motor power supply. Its a boat anchor if it ever fails... Watch the electrolytic caps, the things in alu cans with plastic wrappers but bare tops. If you see even a hint of bulging of the top of one of those, replace them last week if not before. I haven't read any horror stories about those, yet. But I am a retired C.E.T. and have been seeing problems with those ever since switching power supplies, with their light weight and high efficiencies causing a wholesale shift to their use for nearly everything. Switching power supplies however are _not_ good power supplies for this use, they cannot absorb the energy recycling currents that flow in these chopper stabilized drives without either letting the output voltages soar out of spec, or seeing it as an error and doing a protective shutdown, usually in the middle of the most intricate cut of the job. Been there, done that, built the linear, unregulated but huge output capacitance (75,000 uf, it was handy in my junk box) rig I now use in self defense. It hasn't even gotten warm in 5 years of running 4 motors on my mill, sometimes for several days straight. In any event, I don't think I would, even with heat sinks and fans, push those at above 2.0 amps/motor. That limit will only effect, generally speaking, the amount of force available at slow speeds. Only more voltage can get you above something like 20 a minute, and that will probably need dampers on the motors to achieve that. I'm at about 27.5, so I can go a wee bit faster than the std 24 volt supply will get you to. 30 is pushing the envelope and may let the smoke out of these chips. I run at 2.5 amps, but you could say I have extreme cooling too. For motor dampers, there are several designs extant. Mine are big fender washers with sheet rubber between them in loose stacks, others have used weighted skate wheels and such effectively too. You can see mine, and I'm sure others here will also give links to their designs, on the back ends of the motors you can see in my mess at http://gene.homelinux.net:85/gene/emc, that bypasses the front page but only shows you filenames, click to see in most browsers.

Re: [Emc-users] Parallel port issue
Hello! I have NetMos Technology PCI 9835 Multi I/O Controller with 1parallel an 2 serial ports. When I configuring it to work in out-mode - it works fine, 12 outputs and 5 inputs(i have checked outs with multimeter and ins by wire with the 470 R ). When I configuring it to work in in-mode, in hal configuration window I see that pin names have changed, but it works exectly as in out-mode, e.g. pin 2 named pin-02-in - but it does not in, 0V between it and ground. What is the matter? May it be non-bidirection controller? Eugene I had a similar problem over the weekend. I tried to assign an integrated Parallel port 0 as cfg=0x378 in, and it would not be accepted. Eventually I tried it as port 1, ie. 0xd000 out 0x378 in, with the d000 port a dummy port, and it works! Perhaps it will work for you as well.
