Cutting height fixed at 5mm????

[Chennasami]

Hello.
I did not understand why my cutting height fixed at 5mm in mach3. knowing that at the 2 or 3 mm in sheetcam ?????
I use Sheetcam/mach3/thc
Thanks in advance

I use Mach3, but I'm not familiar with sheetcam. Perhaps you can edit your gcode for the desired cut height. Or perhaps there is a setting in Mach3 that is fixing your cut height to 5mm. What post processor are you using? Perhaps it can be modified.
