Heightmap feature is broken (this is a raspberry related issue!) #1

It seems, that the raspberry pi has an issue only happening on the rpi.

Test on a rpi4 (did the same on an x86 linux system - no problem there).

The heightmap feature always returns an error 22 from grbl when Probe is executed. AFAIK error 22 means that the feedrate was not set.

How reproduce:

Load an .nc file
Click on Create in Heightmap drawer
Click on Auto in Border (other values do not matter)
Click on Probe
CNC starts for a second then the error is shown

Solved it: It seems to be a problem with the default settings.

In the settings is setting for the feedrate when creating the heightmap - this is set to 0.

Hi Simon, Glad to hear it was easy to fix. I'd be surprised if the raspi version didn't behave the same as the Linux version. BTW after I built the raspi version of Candle in qt I noticed there was no settings.ini file (of course). When Candle is run the first time it creates the file with default settings. For example all the colours in the 3D window are black. So I created a settings file which has some reasonable colours, a serial port with the grbl baud rate of 115200, etc and included it in the Candle_x_x_x.zip file.
