How to zero the home position for Comgo Z1

Hi,

I 'm fairly new to the laser (Comgo z1 10 watt). I’ve been having trouble with the zero or home position. I’ve been getting by with current position for small projects but when I need to make something bigger the laser runs into the side and triggers a hard stop.

Also, when I click on ‘Home’ or ‘Origin’ it hits the side and I get this:

ALARM:1

Hard limit triggered. Machine position is likely lost due to sudden and immediate halt. Re-homing is highly recommended.

Any help would be greatly appreciated.

Home the machine on power up and use Absolute Coords in the Laser window. I only use Current Position with the rotary. User Origin is only useful if you do not have limit switches.

You do have limit switches, right?

Yes… I think I have limit switches. I tried what you suggested. When I frame the project it hits the limit switch and triggers alarm and stops

This suggests your machine parameters are not set up properly. You should not be going onto the limit switches.

Question: Does your machine Home properly?

HOME

  1. Trolley and gantry rapid move towards the switches.
  2. When the switches are hit, the machine will stop and reverse.
  3. The machine will pull off the switches slowly until the switches open.
  4. The machine will reverse back onto the switches very slowly until the switches close.
  5. The machine will reverse and pull off the switches slowly until they open.
  6. The controller establishes this as the Home position. It is usually shown as something very close to 0,0 as the position if the controller is set for the first quadrant. If it shows large numbers, this can be changed with the G10 command.

There is no other version of the Home cycle. If you have limit switches, this is how it should work.

If you do not have limit switches, where it powers up is the Origin. Home is a machine mechanical function. Origin is a software design position. They are not the same thing.
