How to zero the heightmap.csv?

pro3d · 9 Jul 2018, 07:55

Is there a command or should I just use notepad?

I wonder if there is a way to zero out the heightmap file so all triggerpoints are zeroed out?

I dont trust the M561/G29 S2 and I dont want to accidentally call the heightmap so I want to clear the table

I also still wonder why we have both M561 and G29 S2 in the DWC menu as it confuses me.

I am told they do the same and then the quite opposite but think this is a delta thing for G32...? It should be cleaned up

Just delete the heightmap.csv file, then you will get an error message if you try to load it.

The reasons for having both M561 and G29 S2 do the same thing are historical. They execute the same code in the firmware.

You can edit the heightmap.csv file in notepad, excel or the DWC. Just make sure that you keep the commas and filetype correct and you will be fine. This is what my flat heightmap.csv looked like:
