Had Aspire and shopbot Alpha for 4 years. Every time I create a 3D model with raised text I get lines carved into the model. It doesn't show up in the preview. I've tried the add feature as well as the merge. I can remove the text and run the same file without problem. It's only with raised text. This is nothing new. Been dealing with this since day one. It's not a machine or bit problem. Can anyone help. Attached a photo. Hope I did that correctly IMG_2007.jpg
