I’m curious if anyone has done the crown test from fusion 360?
If so I’m wondering what settings were used; what tool did you use for a “pen” tool.
I’ve done the crown test generated from V1’s site and would like to duplicate it in Fusion as that is the CAM I am planning to use. And before you ask, why not estlcam? I just don’t want to spend another $50. 
@bryanw53
thanks,
what did you use for the tool. F360 only has cutting type bits; as far as I have seen there are no options for pens. I supposed I could make one though.
did you modify anything for feeds and speeds?
any chance you would be willing to share your file. I’d like to see how you set it up.
Trace is a good option, I usually select the v-bit for this, but I am sure many others would work.
I wouldn’t worry about not using Estlcam, for some reason it seems to be the defacto go-to CAM software for hobbyists (at least here); but I found it to be an unusable mess.
@thedevilsjester
Yup, found the trace. Thanks for the vbit info. I will punch that in.
I might also make a pen tool and see how that goes.
Yes, I told it I had a fake bit and really used the pen mount. I set the target depth to control tension on the pen
@bryanw53 @thedevilsjester thanks for the help guys. I got it to work. I also made a dimensional accuracy test with of a 9" circle with concentric circles every .5" offset inward. With a box around it.
I am glad to say that I don’t think I can get it more accurate then what it it is. Its spot on!
The only issue I had was I initially didn’t turn off the Z prob and didn’t realize Repetier host was waiting for that input. Once I turned it off it worked perfectly.
The default-to-Z-Probe bit me too when I first ran mine.
I highly recommend getting the Z-Probe, its worth it. Otherwise it can be difficult to get the same spot and the same height after a tool (end-mill bit) change.
Agree. The Z-probe fantastic
Yup I have one. Just haven’t gotten to figure out how to use it yet . that is next on the list.
It’s trivial. Once you “assemble” it, then just plug it into the board. When you need to use it, put the alligator clamp on the bit, and hold the probe under the bit/tool (router off!).
With the LCD, its just clicking the knob with your free hand, and the bit will lower slowly until it touches the plate and then raise up again, and the go back down once more (slower).
Be careful, if you forget to attach the clamp to the bit (or it got unplugged from the board!) then it will keep pushing the bit into your work surface. Also make sure that you hold the plate flat until its done.
I recommend testing with a piece of foam or soft material as your work surface (under the probe) for the first time, just in case it’s not working. Pushing the probe into foam is a lot easier on your bit and gives you time to abort. Not much time, but its enough if you are ready!
