Work surface leveling gcode didn't work.

Mostly Printed CNC - MPCNC Troubleshooting
1

I tried to make a level surface. I have cut a few smaller things, but this is my first big cut.
Could I have a setting wrong in the firmware or did I not use Estlcam correctly?
I think the gcode wants me to make a tool change. I don’t need to I just want to continue to finish with the tool in place.
I am using the beta firmware, Ramps 1.4

I was expecting the entire area to be smooth.

also at a similar stage and looking to mill flat my work area, any tips or how to’s would be greatly appreciated…

I found a website www.easel.com
you can generate gcode and download print. I was able to make my flat work area, and for the heck of it I carved my name into it.

thanks for the link Jeremy, not a bad little site… what size bit you thinking of using??? nice little apps within the site to generate box’s and the like… will enjoy playing

Change your step over to 50% or even 45%, double check the tool # in the roughing and finishing box. you might want to make shallower passes. You just want to skim the surface quickly.
