I'm looking at controlling a X-Z gantry system w/ LinuxCNC (well really HAL and some code). Operator pushes a button and the gantry moves between two baths, waiting for pre-set seconds per bath. The positions are set and do not change.
I was thinking of using a Mesa 5i25-7i76 combo and maybe a 7i32 1.5/3Amp or another off-the-shelf stepper driver. There's no-magic needed for this. I need some I/O for limits, home, inputs, outputs, etc. I realize the 7i76 is overkill for axis count, but I might want to expand to 4 axes later. I would take one of the GUI interfaces (touchy or axis, etc) and make my own suitable interface (easier said than done, possibly). The bath has a Love temp controller (16A2133-996) that can communicate Modbus RS-485. The 7i76 has RS-422 serial and the PC would have a RS-232 port. What's the best way to get to RS-485? I could use a RS-232 to RS-485 converter like this one from advantech: http://www.mouser.com/ProductDetail/Advantech/ADAM-4561-CE/?qs=%2fha2pyFaduhMyuR96x%252bdp4DnBDFhtESzKcpNyIUxvYPu1PngEfDtkA%3d%3d I thought maybe someone would have a suggestion? Might the mesa smart serial RS-422 be able to work someway? Regards, Mark PS. Considering my monitor turning off issues (previous posts), I'm second guessing using LinuxCNC/hal for this, but I'm a glutton for punishment.. You just can't beat the price/feature linuxCNC. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
