Little Emco lathe with some pittman servos... Amc drive that takes PWM+Dir. https://www.youtube.com/watch?v=sUz5ZZyf2LU Of course caveats.. -with the input scale of 50800/inch - speed limited to about 35ipm. (probably fast enough for me) -Tuning has to be good - because if there is an oscillation - it oscillates faster than the computer can count.. Other than that.Seems like it would work ok... (a mesa card like the 7i92 would be way better) but this shows that you could get into basic closed loop servo control for the price of a printer port - you can still get them and pci-e is still a thing.. sam ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] 6i25 PC spontaneous reboot
I think that the problem is the motherboard. I pulled the MOBO/CPU from another machine. Put it all back together and it is running like a champ now. It's always a crapshoot with these new motherboards/cpus. They seem pretty iffy... keep trying them until one works. It's always been that way for as long as I can remember! Thanks!

[Emc-users] 6i25 PC spontaneous reboot
So I had a power outage last week and it took out the PC of my cnc router when the power returned. PS died and took the MOBO with it. It was 7 years old so not a big deal. I upgraded to an MSI 320M PRO-VH with an AMD Athalon 3000G. I was previously running a 5i25 but this board doesn't have a PCI slot so (until the adaptor comes) I pulled a 6i25 from one of my other machines. My setup is a 6i25 with 2 7i85S boards attached. All power is supplied to the 7i85S boards via a separate 5v power supply. All the jumpers are set properly. They are set to standard defaults as is described in the manual. W1 down W2 down W3 down W4 up W5 up W7 down W8 up So far so good. I have everything booting up and the machine starts up and it appears that all functions work properly. With the machine enabled and no motion commands going it works properly. However when I start jogging any of the axis the PC resets and then restarts. The spindle works properly (VFD controlled by USB) and doesn't cause the reset. IO works properly and the machine is enabled so the velocity loops are active meaning that the 6i25 is functioning properly. It has sat idle for hours with no reset.
