There is a complete world outside G-codes. I will give an example. You have a servo with an encoder with 2000 counts. 50000(khz, system frequency) * 60(minute) / 2000 = 1500rpm system max. This give the highest resolution. But if the max rpm of the servo is 3000, then you'll never reach it with the system frequency. This is an existing problem on this forum. So if you need speed, that's where you also encounter inertia, you can trade resolution for speed, with this software trick. The alternative is lower encoder count, that's sacrifying resolution for speed.
I would'nt be surprised if it's automatic in your box. (Shht, I use it) |
