GBR Candle - Heightmap checkbox disabled, why?
Hi!
I'm new here on this forum and in the world of cnc stuff.
I bought a diy cnc machine from China.
The DIY 2418 machine, I wish to use it to make my prototype pcb at home before I send it out to
make professional pcb's...
For creating the pcb I use the NI Ultiboard software.
For generating the gcode I use the Flatcam software.
I use the GRBL Candle software to send out the gcode.
Everything is fine jut a few things are making me crazy!
1. In Ultiboard I can't export the excellon drill file but I can export a drill .gbr file.
How can I use this gbr file for drilling my pcb ?
2. In the Candle software, there is a "Heightmap" option.
This option is working well, but I don't know is it enough just to measure the
PCB deviation with the Heightmap option and just send out the gcode?
Or I have to do some other tasks with the Heightmap result before I send out the gcode?
There is also a checkbox in the Heightmap window "Use Heightmap" but this is non-stop gray - disabled.
Will this function automatically correct the Z depth when I try to mill my pcb after I measured the surface
deviation?
What I doing wrong?
Thanks.

Hi in the software for the height map, you need to make sure that there is a circuit upload first, then it will be available. I have a CNC 1610 and it uses grbl the same program, I was not able to use heightmap because there was no circuit to z-prob. Check out my YouTube video to see how I made a PCB, including heightmap/z-probing.
This is the link to the video: https://bit.ly/2G9fo9l
I will make a tutorial soon
