scara arm grbl, cant go to all coordinates

I've made a scara arm (attached image) and im trying to use this version of grbl that supports a scara arm, it works as intended but has a slight problem, it seems to stop me from going to specific coordinates, for example, I can go to (x100 y100) but can't go to (x10 y100) or any negative coordinates, which should be possible, is there something in the code preventing it from going here, as both my arms can rotate 360 degrees so I don't need limits. also if I enter some coordinates it doesn't like it seems to crash and become unresponsive. does anyone know how I would go around fixing this? thanks

grbl version: [github.com]

... is your program capable of calculating "singularities"? - maybe there is some limit to avoid problematic kinematic positions ...
