Hello, I am new to Fusion 360 and had an incident the other day where I bored straight through my work piece and into my table while trying to engrave some text.
I use a 2D contour pocket as the toolpath operation and used a 1/4" bit. I did not draw a blank for the text to engrave into since I figured I could just offset my heights and drawing a blank would not be required. I manually zeroed my machine on the bottom left corner of my work piece. My intention was to pocket an 1/8" into my workpiece but I ended up going straight through my work piece and about 1/8" into my table.
All that to ask the question, do I need to have my blanks drawn in Fusion 360 to engrave text or do you not need to do that I and just set my heights incorrectly? Iāve attached the file for reference.
I only had a quick look but I donāt see something obviously wrong in the file.
From the description, it looks as if you had zeroed the Z axis off your table and not the top of your piece (in the attached Fusion 360 file, you define your coordinate system with Z at the top of the piece).
Alternatively you may have changed the bit and forgot to zero Z for the new bit.
One thing I forgot to mention is that I dont believe I homed the machine before running the program. Not sure if that played a factor. Also, from my initial post, I should have clarified better that I zeroed my machine at the bottom left corner of the TOP of my workpiece.
But what I gathered from your response is that I shouldnāt need to have a blank drawn for my program to run correctly?
Indeed I only had a quick look and I did not noticed but you have only drawn the sketch. The part is not modelled at all.
Iām not sure that I can help: I have never created pockets like this. I always extrude a 3D part in CAD and configure the paths on the 3D model.
From the warning it would appear that Fusion 360 cannot set the WCS correctlyā¦ (the part coordinates) and you have a coordinate problem. There might a link thereā¦
