GRBL homing fails on every one #1283
Description
ive tried several grbl boards now, cheap ones and expensive ones.
cannot get passed homing on any of them, copied a board ive been running for 5 years or so and works perfectly well, but all the new boards ive tried now have error 9 or 15 always homing problems, even when i copy the old board not will accept switches hard or soft ?
beyond
me and cant find an answer to the problem.
application is a 2 d plotter i built and has a solenoid out put and the XYY axis off 2 stepper drivers, not arduino just GRBL control boards.
Anyone with the slightest idea why i cant reproduce this any more.
