“An unknown error (29) occurred while compiling project. Please report this problem to LHR Technologies for a fix. Cannot continue, sorry.”
This error message occurs when trying to upload a project with a keyhole that has the depth setting out of range. The keyhole function defaults at the most appropriate depth at .325″, so it is rare that you should ever need to change it. If you do need to change it, the range is between. .45″-.25″
Solution
- Change keyhole depth to default – .325″
- Change keyhole depth to be within range – .45″-.25″
