To parallel the “ Post up them projects ” thread, here is where you can post your failures, and hopefully what you learned. Here is me learning to cut aluminum: [image] What : 2mm thick 6061 (I believe) aluminum Damage: $50 worth of end mills and about twenty hours. Process (so far) : Fusion360->…

@TugBoat - I love this idea! I’ll be following this thread and most certainly will be adding to it… lol Here are some failure quotes I’ve said myself and heard over the years; Success and wins are great and feel good, however our losses and failures teach us so much more and truly make us who we a…

Poor clamping and poor patience. :slight_smile: [0807211529]

Well, been there and flat done that! Lessons learned for sure.lol

My setup… make sure your CNC isn’t a parallelogram or skewed. Unless you don’t mind cutting parallelograms when you mean to be cutting squares. After I noticed the issue I found even my Y axis was bolted at an angle. [IMG_6666] [IMG_6709]

Well this was not good. Smoked the collet nut and froze the collet and bit. Had to take the spindle apart and heat the outside with a torch to get the collet and bit out. Broke the bit taking it out. I tried to use too short of a bit to do a finishing pass on a deep 1.75inch bowl. [20210812_101135] …

Ladies and gentlemen I have discovered that vibration is bad. In the post mortem it was obvious that my bit had loosened and because it was an upcut bit, it dug in deep! This was my first experience with the machine bogging down and losing steps. But to be fair to the 1F it was trying to drive a 1…

Not sure what happened. I’ll take a look at the vcarve file. But I never got to designing a profile. And especially not that low. On the Y axis. Also xy origin previous to cut had been off by 2 inches, no explanation on that. 5 hrs down the drain. Last check was 14 mins left. So this happened durin…

Finishing run complete. Went to rerun my roughing pass with a raster toolpath to cleanup a few areas and apparently my machine lost it’s point of origin in the process… I work mostly with rough-cut lumber and getting an exact math from probing X and Y multiple times isn’t likely. Going to do a litt…

I think it’s Raster. Try along the X or Y. I just tried a third time on a 3hr carve, changed from Raster to Y axis cut and was successful. Not sure why this is happening.
