I have read tons of post about this problem, but nothing we’ve tried is helping and my husband is seriously getting ready to throw in the towel because we can’t get passed this to run anything. I apologize for asking something that has been answered before, but I don’t know what else to do at this point. We have the Crossfire 2x2 plasma table with razorweld razorcut 45 cnc with x45torch. The basic of all basics. We have decided to add the Crossfire z-axis + THC upgrade, it says it won’t ship for 2-3 weeks and i’m not even sure that will fix this error message.
MACHINE ALARM
IHS Fail. The torch is not in the expected initial state before starting the IHS cycle. This may be caused by the following:
insufficient slack in your torch cable…Not the problem.
Make sure that the IHS cable is plugged in, (it is) and the IHS indicator light at the bottom of the screen is grayed out and not highlighted Green when the torch is not touching the material. (Ours is ALWAYS green)
We can’t even figure out how to turn it off. Ive read that it can be done in Fusion and in SheetCam but can’t figure that out either. It lets us dry run it, but when we try to cut, this pups up every time. Will someone please try and us before my husband gives up on this? Thank you!
If you don’t have a Z-axis on the machine currently, the problem is that your G-code file has been post processed with the wrong settings.
When you set up your tool in CAM, you must set the Pierce height and Cut height to zero. If those values are not zero, the post processor will include the IHS(initial height sensing loop) in the code.
The IHS loop is what tells the Z-axis to probe the torch down to the material and set the material height. If you don’t have a powered Z-axis on the machine, Firecontrol is not receiving the expected feedback from the IHS sensor, so it throws an error code.
When you get the Z-axis and THC upgrade, you will have to change the tools to include the pierce height and cut height, but for now they must be set at zero for the program to run.
@ds690 is exactly correct. If you do not have a Z-axis installed on the machine yet, then Z-axis commands that are included in the G-code will result in an error message. You will need to disable the Z-axis commands for now until the Z-axis kit is installed on the machine. If you are using Fusion 360 to create your G-codes, you can find more information specific to this here:
To you BOTH, thank you so much for responding so quickly. We will work on this tonight and hopefully we’ll be able to cut something this weekend. I will for sure update you either way!!.
