Tool change height was created by krrice
Hi, I am using Linuxcnc and CamBam. I have the basics down, now I am trying to do engraving. What I am trying to do is engrave some text then cut out an oval with a different bit. I am having trouble finding where to set the height of the z axis for a tool change. When it is time for a tool change it stops but does not raise high enough to get to the Collet on my router.

Hi
www.linuxcnc.org/docs/devel/html/config/ini_config.html
Have a look at TOOL_CHANGE_POSITION= in the [EMCIO] section as well as a couple of other possibilities

Be careful with that and CamBam.
CamBam by default put in a rapid to "clear height" before a tool change, but if you have TOOL_CHANGE_QUILL_UP then (in a sequence of events I haven't quite figured out) you can end up with a tool crash when starting from line with a longer tool.
If you are using TOOL_CHANGE_QUILL_UP then change your CamBam settings.
"System" Tab, Post-Processors , LinuxCNC. The scroll to the bottom in the lower pane and look at "Tool change"
Click the line and in the edit box changeto
I think I also had to actually add the G43, thinking about it.
