Connectors - limit X , limit Y



I need to install X Y limit switches on the machine

The controller has connectors - limit X , limit Y, limit Z.

They don't work.

What need to do that they work ?

Thank you for answer.

i agree I keep banging the laser against the frame because there is no ALL-STOP button

Just connect the limit switch in parallel connection then connect it to the limit switch port

Thank you for fast answer ))

I connect limit switch - it not not stop, not pause.

(controller: "Laseraxe USB CNC 3 Axis 2 Phase 4 Wire Stepper Motor Controller Driver Board CNC Laser Engraving Machine Mainboard" , soft CNCC v2.53)

Hi, I need the z-limit to work. The connector for the z-limit is wired to arduino pin 12, so that seems to be right, but the controller software does not react (x-,y-limits also don't work). Is there anything to activate inside the grbl-software? Do I need to update the grbl-software? It is very important for me, because i need to level my machine to engrave my PCBs.

Has anyone been able to get the X and Y limits to work? I have tried shorting the pins while jogging or in a run in V2.53, V2.53, and 2019 with no success.

@Andy I will try this soon. Do you have a part # for the connector?

The switches have to be properly wired and connected. Best to use the NO (Normally Open) position and then make sure that the other end connector is properly set up to match that on the board when plugged in.


There is another way! It's more expensive, though. You can get a different set of axis driver boards to replace the originals. SILENTSTEPSTICK - TMC2130 STEPPER MOTOR DRIVER

It's not cheap, but when set up properly, they don't need switches to detect that they have hit an obstacle.


A great video that covers updating your engraver can be seen in the following link. It says that it is for EleksMaker PCB laser CNC machine but all the upgrades will work with most similar laser engravers. There are links on the Youtube page to the wiring. I will probably go this route when I can afford to.
