hi, so what am I doing wrong? went to download grbl on the 64bit pc I plan to use as controller. the site (maybe wrong one) tells me drivers are out of date. OK, follow prompts and a paid for Microsoft driver update sub later I think all is good. Same circle jerk over and over. scan and update drivers, follow update promps, shows no out of date drivers, attempt tp upload and back to scan for outdated drivers???
