Hello I create a small cnc for a diode laser and works very fine with lightburn software Now i add two limit switches to homming this is the board i use ๐Ÿ‘‡ The problem its when start homming and reatch the limits the machine wont stop! Thanks ![image](https://forum.lightburnsoftware.com/uploads/default/original/3X/b/4/b4127d725dbbe71fc022626e26c87eae0def9538.jpeg) ---

What types of switches do you have and how have you wired them? ---

Assuming that the switches are correctly connected to the board, has the function been activated and configured? ![Homing and Hard Limits](https://forum.lightburnsoftware.com/uploads/default/original/3X/a/f/af3d9ef94fb3f9886405bcc7aae16e8977f42202.jpeg) ---

From what I understand, I would say that the limit switches and homing are activated. The limit switch signal will probably be inverted and it will be necessary to change wires. But wait for opinions from those who understand much more than me. ๐Ÿ˜‰ ---

Are these NO or NC switches? How have they been wired to the controller? > [@pedrogaia](#): > > grbl 1.1f if i flash for 1.1h its better This will not make a difference. ---

By default GRBL expects NO switches. You can invert this in GRBL $5 (Limit pins invert). Try switching to 1 and retest. ---

How is it currently wired? Power cycle the laser after making the switch. Are you able to rewire the switches to make them NO? That might be preferable since your switches arenโ€™t equipped with any current limiting circuitry. ---
