Hi, I may have a nice project of retrofitting a lathe (about 20kW, quite a nice toy, but with an old control that is dead)
I tested servo driver, they work. So basicely, all I need is: - 3 output +- 10V (to give speed consign to servo amplifier) - 4 quadrature input encoder (I checked this, its a 1micron 1 increment, pretty simple), 1 channel is for MPG, another for spindle position this shall do the job for the main axis, then I still have the tool changer, but it seems pretty straightforward (a bunch of IO to drive in the required sequence). Of course there is a lot a digital IO, but I have schematics, thus is seem pretty straiforward as well. I would also love to have analog input on MESA card, but this does not seems to exist. anyone to confirm ? (use would be load monitoring, spindle speed override, axis speed override, I can do this really simply with a small USB card, I did not need real-time capabliites) Idea is to use MESA 7I33TA for +-10V out and quadrature inputs, and 7i37 or similar for digital input/ouput. What card shall I use assuming a PCI or PCIe port ? i would like to work with the 5i24-16 or 5i24-25, but there is no information ( or I did not find any). As much as I understand, these card use FPGA to make PCI interface, as opposite to 5i20 for example, where there is a dedicaced chip for this. Is there LinuxCNC support for the new generation board (5i24, 6i24 ) ?
