HS 98 regulation program

[ViperII]

I have a Gemini FO 3015 Laser
When I go to run the HS98 Regulation program for the heigth control the head will come down to about 3 inches from the plate and then stop. It never makes it down to the plate to sense it. It doesn't throw any alarm it just stops and sits there. In the program it shows that it has stopped on a M727 in the program. Any ideas on this would be greatly appreciated.

do you have trace off lit in the sub panel before running that program? Also do you mind posting up the code from your program, it could just be setup wrong.

Yes I had the trace off on and I also had Amada send me a new HS98 program loaded it up and still the same thing. I went through and ohmed both of the z-sensor wires, the cone, and replaced the nozzle. I tried to cut a part without running the HS98 program, the machine will come off of home position to the start point of the part, head starts down but then retracts to where I get a Z Overtravel alarm.

we had a similar issue and it was the cone that needed replaced.

The reason why it is stopping is because the capacitive sensor is sensing something other than the material. Usually this is an indication of a damaged cable, cone, or one of the connection points.

From the tip of the nozzle to the inside of the SMB connector should read less than one Ohm (or there about).

Came in biginning of shift fired it up and ran the HS98 program and it acted like nothing wrong. Good to go for now, I'm thinking it might be the HS 98 board. right now its working fine. If something comes up I'll post it. I hear those boards don't come cheep, over $7K.
