My rules is do NOT try and build everything at once. Build up only the smallest amount and then TEST it before building the next part. Even little things like a power supply. Testthat under a dummy load, look for noise and heat, then connect it and check volts and so on again. Same for steppers and timing belts. Don't use anything as complex as LinuxCNC to test a motor. Build/Make or buy a very simple pulse generator for motor testing. An Arduino comes in real handy because you can use it to verify motors and sensors with very simple sketches. Figure some way to test each sub-system in isolation and do that before you integrate it into the next larger sib-system > 5. is there any cheap and compatible tool changer for raspberry running > linuxcnc? > This is a hard problem. You will need to design and build it. The simplest is an LED and a human with a wrench to watch it. Tormach has a system based on a power drawbar and tool tray. > > > ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
