Suggestion for improvement to SOFT LIMIT feature

ytliu

Thanks, I will adopt your suggestion.

Ver:2018-10-12-102 Description:
1. Add G20/G21 recognition macro variable (#448): in G20 mode, #448=25.4; in G21 mode, #448=1, used to correct the bug that G28 and G153 instructions execute errors in G20 mode;
2. Correct the error that the detection command M101/M102 stops processing during the machining process;
3. Change the soft limit response mechanism in the manual mode, pre-judicate the soft limit, and increase the #2032-#2035 pre-judgment coefficient to adjust the pre-judgment bias.

The soft limit response mechanism in automatic mode has not changed temporarily. I agree with Nikolay81's idea that it should be discovered and prevented in advance. However, scanning gcode file can take a lot of time, especially for larger gcode files. Let me consider it again.

probe instructions
M101 or M103 is used to turn on the probe func. After turning on, in the subsequent motion, if the probe signal is found, the motion will stop. M101 differs from M103 in that the effective level of the probe signal is different.
M102 is used to turn off the probe func.
M101 or M103 must appear in pairs with M102.
E.g:
M101
G91G01Z-100F_
M102
G04P0; synchronization, where P must be 0
M103
G91G01Z100F_
M102
G04P0; synchronization, where P must be 0
G90G92Z_

First, M101 turns on the forward probe func, then the Z axis moves down 100mm at the set speed. In this process, if the level of the probe signal changes from '1' to '0', the motion stops, then M102 turns off the probe func, and Synchronize.
Next, M103 turns on the reverse probe func, and the Z axis moves up 100mm at the set speed. In this process, if the level of the probe signal changes from '0' to '1', the motion stops, and then M102 turns off the probe func. And synchronize.
Finally, execute G90G92Z_, set the Z coordinate of the current position to the set value.

#448 is a macro variable, not a parameter. The parser assigns it, if it is in G20 mode, #448=25.4; if it is in G21 mode, #448=1.

Your advice on the soft limit is very good, I will increase the corresponding processing.

Please tell me your relevant parameters and provide a simple test gcode . Thank you

When #2031 is set to 1, when the component of acceleration(#99) in each axis is less than #45-#48, the acceleration is determined by #45-#48.

I watched the video, I think there is no problem, the action in the video is consistent with my design idea.
