JL4a.bin.txt (44.3 KB) This is special version for JL4, identical to above JL1V2 firmware with exception of applying upper right coordinated at reset (G130/ G131). Please apply your specific JL4 GRBL settings, defaults in attached JL4 firmware are still for JL1.
While it stops at home - your coordinate space should be correct with 0:0 at bottom left and positive space. It will not go there automatically but it should not affect normal operation. Try to open any job file and frame it.
