Everything is quite clear with parameter Jerk and the principle of its operation. You were right as to its operation at very small movements, it really does not allow the machine to get the set speed, which is good illustrated by Step response. If you are interested, here are my settings of speed, acceleration and Jerk:
Code:
ch0->Vel=320000;
ch0->Accel=1500000;
ch0->Jerk=6e+006;
ch1->Vel=340000;
ch1->Accel=1600000;
ch1->Jerk=6e+006;
ch2->Vel=230000;
ch2->Accel=1300000;
ch2->Jerk=1e+007;
You can also view a video which demonstrates the maximum speeds of motion using G0.
And what about the first two paragraphs of my theme, namely offset storage and hot keys. Could you tell me when we can wait for their realization, it's very important for me ?
I have also another, probably a little bit stupid, question: How can I make the machine raise the spindle when G-code pauses or stops? I know that there is C-code External Buttons, but I actually can’t understand how it works. Could you show me its work by example of any button, please?
