Hello, I am new to all of this, so I apologize if I say incorrect vocabulary or don’t understand simple concepts.
We have a local robotics team, and the person that setup the Crossfire Pro has graduated, all the knowledge of the assembly and setup gone with him (never had time to teach or even cut).
When looking closer at the IHS, the setup looks slightly different from one of the pictures of the documentation, and there is no continuity between the tip of the torch and the negative lead of the IHS. I was wondering if I was missing a part to trigger it, or if it’s just user error. I would run a test probe, but after searching I am unsure on how to do that.
There is not supposed to be any connection between the IHS system and the torch tip, because it is not an ohmic sensing system.
The IHS system is a simple normally closed switch. When the torch lowers and comes in contact with the metal, the floating Z axis carriage and the Z axis lead screw assembly separate and open the switch. The switch opening triggers the Z axis to reverse direction and close the switch. When the switch closes, Firecontrol records that location as Z zero.
A simple way to test the switch, is to jog the Z axis up so the torch is about an inch above the metal surface. Lift up on the torch and watch the Firecontrol screen. You should see the IHS indicator turn Green when you lift the torch and go back to Gray when you lower it.
We have seemed to find out issues. What I was more concerned was the connection between the negative and positive leads, as the part is acrylic (therefore does not conduct electricity) and they leads were isolated with each other. I should have mentioned that the IHS was reporting it was always tripped.
On the floor near the machine, we found ad brass part that we figured out connected to the positive lead and touched the other brass end the negative lead was connected to, which fixed out issues with the IHS.
