@Ian-0 yes it's a safety feature. However, we have a feature request to allow it to be overridden for special purposes such as focussing the laser. Meanwhile, a workaround is to create a dummy axis (e.g. U) using M584. Then you can send e.g. G92 U0 G1 U100 F100 S255 to turn the laser on for one minute

@ian-0 Hi, I don't think it's skipping steps. That would produce some of the desired path.

I'm not entirely clear on what it's actually doing. Are you saying that it cuts the two grooves we see then comes back and cuts them again and again and then it stops? That would be bizarre. It could be that it's deciding the cnc hasn't parsed those two chunks and it sends them repeatedly until it gives up I suppose.

I'd also vote for seeing your config.g file for RRF.

One simple test you could do is manually move the CNC head - following along the G-code roughing file - just send each line individually in the console, except the Z offset, (without the N prefix) and see how the head moves.

@ian-0 I have now - finally - got it sorted.. I am now using the E6STOP input on the expansion port connector and GND pin with pullup and inversion applied. M558 K0 P8 C"!^exp.E6_STOP" H0.7 F120 T3000 . Thanks for all your help.
