There are a bunch of benchy speed runs out there, and I find it fascinating. This thread got me thinking. We have all sunk a bit and been amazed at it plowing through really deeply just fine. How about we intentionally push things? What sort of speed runs could we do? I was thinking a specified de…

I’m on! I guess it’ll matter what type of bit we’ll use? The regular 1/8 single flute?

No way that is part of the variables. I’m excited to see how a $4 bit does against a $40. I used the router by hand (GASP!!!) with a expensive 1/4" single flute yesterday…I didn’t even know I was cutting anything. I thought I forgot to lower the bit past the guard. I planned on testing the current …

For a speed run, you should mostly care about speed, but you should post some dims. It’s just for bragging rights, right? So people posting their total time and some dims. Bad dims still count, in my book.

In school when we did things like this we had scoring equations. Speed would be the largest factor but if two people got the same speed, accuracy added in. Just need to decide how much accuracy is a factor. Think of it this way, if you scaled the cut a tiny bit you would cut less material=faster. I…

Also to, like fighting or racing, should there be a class hierarchy? I’m sure a bone stock 30x30" C build won’t fare well against a heavily modified thick-wall 18x18" stainless build with NEMA 34s.

Heck no! Lets see how a modified does against a stock! Is build size really the largest factor?

Now this is sounding like new version research…not as fun as beating the crap out of them to get a better number.

Don’t forget, I made that paperweight on a five foot square machine. “Standard” size would have been easier, but where’s the fun in that?

So maybe factor in usable volume

Total score = Total time * (1 + abs(error/expected size)) So if you cut something 95mm that should be 100, in 10.00 mins would be a score of 10.0 * (1+0.05) = 10.5min? You could square the error, but honestly, is anyone going to go 5mm over or under and submit the score?

Cnc race! Random or Off Topic

Ladies and Gentleman, get ready to break stuff!! Let’s see who can make a decent* cut the fastest. Rules: 1 - Use this DXF, import in millimeters.100mm_drag_racer.zip (8.3 KB) 2 - 12mm Depth of cut. 3 - Only in MDF (MDF should be fairly universal, making the test as even as possible). 4 - Take a video (we might need proof, you don’t have to post it unless it is really fast or something breaks!) 5 - As many attempts as you need, post them all, lets see how you improve! Any tool, spindle, …
