What causes z travel exceeded?

Good day.
still a bit of confusion here…yesterday I cut allot of pieces all went good.
today I needed to cut an expensive material so there is no room for mistakes.

I cut 2 samples all is good.7mm…spoilboard dig in set at .06
then redid worksurface calibration.
I load the new material 18mm xyz zero all, load the gcode machine ask me to measure the tool send to tool height setter ok send back ready to cut but when the machine send the bit all the way up and tells me your tool has been measured (this is when it is in graph screen) the z indicates it is at 11" which I know is going to be trouble. so I escape the screen zero my z again (with pendant) cycle start to cut now the z measure 5.8")
it did cut good.

so maybe always zero after the bit is measured?

so Now I always look at the z in the graph screen before cut …where I am going wrong here…and yes I saw the video about 10 times :rofl: maybe I still missed something.

also can you send the toolchange into a generated intercon job?

Thank you!

Why are you doing this before cutting a job? It only needs to be done once for your work surface. The only reason you would need to do it again is when you resurface your table. I think this is where some of your confusion is coming from.

It did this because you re-measured your work surface. When you do that you clear out your tool heights so you have to go back to the tool height setter to measure your tool again.

Hello I did the work surface to push it a bit below the spoilboard to make sure it will cut thru the material about 1/16"

so I can understand if the worksurface calibration will clear the tool height but when you run a new job it will remeasure the tool?

The machine works good …I am extremely satisfied here.
Only e few things are bugging me.
On the router side this zero thing
and also when you load a new file…it does not display the file name…it displays the lets say profile cut1 …whatever you named your tool cuts in vcarve. but when you go into the graph then it displays the real file name .cnc this messed with my head a few times thinking I loaded the wrong file.

Tnx!

Don’t do that. If you want to cut through the table just set your cut depth deeper than your material thickness.

You can do this in CAM.

So in the control if you go to Set Part Zeros>WCS table and look at the Z offset, say it’s .75" if you want cut deeper than that in CAM set your cut depth to be someting like .77" (this would cut into the table .02")

Watch this video:

Yes, but again, only do the work surface calibration if you actually change your work surface (replace it, resurface it, etc) DO NOT do this every time you want to change your Z offset.

Sweet!

The name of the file you have loaded is in the top of the screen:

This shows how the Z height in the WCS table works.
