Lathe with STM32F411

Hi. I made some tests with BlackPill (411, firmware from Web Builder) connected to two generators, one 3200 Hz as pulses, and second 1 Hz short pulses as index. I surprised the G33 (and G76 too) works after M5 (spindle off), not after M3 (spindle on). The second problem I found is why, and for what, the G33 checks first is spindle turns, and gives error if not? The G33 has timeout for case of no index pulses, and in my opinion it is enough. I think, the check is spindle turns prevents from G33.1 implementation, because there is direction change and G33 procedure must starts when spindle speed is zero... Regards.
