switchkins clear taskintf error

hi at all  ...

I use switchkins customized on a scara robot ... plus i use code for reverse singularity with mdi command .... after some test I'm quite satisfy of result.
One things .... there are a minor possibility (power default for ex.) that someone can select syngularity=0 + switchkins = 1 and in wrong position restart with singularity=1 .... these generate following error of joint plus:
.... seems Lcnc after restore emergency keep in mind the erroneus task and try to complete it ... so error come back ....

QUESTION: there are a way to clear unprocessed gcode or mdi command? Because set right singularity value before to enable seem not help .....

regards

i Reply by my own .... I admit a stupid question, only because not remember that exist M66 E0 L0 for sincronize task to actual state and ABORT command for erase all motion task  ... plus not add on my kins a pin for check witch singularity is setting .... Now I do it so problem is solve.
