If i move my laserhead to the left, it slows down before it hits the end (900).
When i turn my laser on the laser head “smashes” in to the right back corner, the limit switch is oke.
It happens only at startup.
Is there anything i can do?
Mine goes back right every time i turn it on. Home is top right, but I have my origin set for top left. Move it to where ever you want and hit origin on the keypad, then hit the reset. If it homes and then goes to your new origin, that’s all it is.
The ‘standard’ sequence is to move to the switch at the ‘homing’ speed and once the switch is contacted, it backs off and more slowly approaches the switch a second time to get a more accurate position. It will light, go out then light again for a homing cycle.
I always forget about the LED’s on the controller. Min’s buried so that I have to practically stand on my head to see them. I just go to the diagnostics screen on the controller. Then I can manually activate the switches and watch the indicator independent of moving the head. The square proximity switches should have LED indicators in the top as well.
These are ‘hall effect’ switches and only work with Ferris metals. The ‘effect’ depends on the existing magnetic field (in the switch) being ‘bent’ by the metal intrusion within the field…
What it’s detecting is not aluminum.
This is an example… The magnet is visible with its S & N ends, the little yellow block is the hall effect device. The metal ‘cog’ teeth are detected by the interruption of the magnetic field from the magnet, sensed by the Hall Effect device.
