Hello, I am running grbl 0.8c and it’s working great. I recently came across a situation where I need the router to cut 90 deg. from the original (otherwise it won’t fit on my table). Can I accomplish this by altering codes in grbl? Thanks.
No, GRBL cannot do this by itself. Some GUI's can do it for you, try bCNC but you can also just rotate the part in your CAD/CAM software then generate new Gcode
Thanks for the response. I never know where to turn when I have a grbl question. The project involves a bitmap image. As far as I know the software cannot rotate a bitmap. I thought that using grbl would be an easy solution. I will look into bCNC. In regards to updating to grbl 1.1; do I have to worry about cad/cam software issues, will the same Post Processor file work, it looks as if there are major differences between grbl 0.8 and 1.1 ?
My understanding is the only major difference between GRBL 0.8 and 1.1 is there was a pin change involving the Z limit switch and spindle control. Basically they swapped them so there is now PWM control for the spindle. This can be reverted by commenting out one line in the config.h file.The only other issue I believe I read about was making sure if you are using universal gcode sender is to upgrade to the newest version, but I don't use that so not completely sure.
There is a lot of software that can rotate a bitmap for you, so you can rotate it before you import it. I use this IrfanView - Official Homepage - one of the most popular viewers worldwide as Hisha said, the only change to worry over is the pin swap, but you can just edit config.h to make it the same at 0.8.
