CARVEWRIGHT MANTLE UPDATE
Give us an update when you have a chance. I hope everything is carving out alright for you. In Mach3, I bump it up to 70ipm and it still seems to be smooth. For the tool settings, I have it set to 50ipm. I'm assuming rapids and inches per minute are the same thing. Swaped out to a 1/16" TBN, 70ipm, 8% step-over.we'll see what this produces after it has time to run for a while.

Thanks, again, for the plans and taking time to walk me through some of it.įlatheadyoungin wrote:Was still getting lines. So, this is my motivation to keep pushing through this learning curve and get it right. I'm wanting to make grandma one of your clocks to give to her at Christtmas (I make make one for each of the 5 children, too). Well, we sawed up the tree into rough lumber. Even though he was sick, he climbed up the leaning tree towards the 10' high trunk. It broke off from being hollow about 10' up the trunk. In his last year of life, some straight-line winds took the biggest one down. In his back yard they had some huge, old growth oak trees. He loved being in the woods and squirrel hunting. Side note: My grandfather passed away about 3 years ago. Thanks for being patient with the newbies. And, I'm sure I'm making this way more difficult than it should be. The 9-10 hour was 8% step-over and 50ipm. That makes sense, higher rapids and less % step-over for a better finish. Then, I'll get a fresh new board and run it with your settings and a 1/16" TBN.

Once this one runs for a little bit and I can see what it's doing. I think, however, Aspire retained my goofy settings. I deleted all my files for the mantle clock a little just before I fired up the machine and dloaded a fresh set- thinking, like you said, I've goofed up some of your settings. It's currently running the raster with the grain (I think this may have hurt it too), 1/8" ball nose (I know it calls for 1/16" but I ran it twice with a 1/16 and neither came out good, once I keep experimenting I'll go to the 1/16), running 50ipm, 10% step-over. I just fired it up and again and came back over to check the thread. Yes, excellent info! Thanks for taking the time and being detailed. The settings in the original files are a good start, but you can tweak if necessary for your own machine and material. Double check those and see if you need to adjust accordingly. I do not know how you are reaching a 10 hour estimate unless your Scale Factor and/or Rapid Rate is very far off, or the bit settings are incorrect. My Rapid Rate setting is 100 inches per second. A more accurate Scale Factor time estimate for that particular file would have been 2.5 (time estimate 5:33 compared to the actual time of 5:32). However, that Scale Factor was too low for the FRONT file. The Scale Factor I set for the project was 1.8, which yielded a reasonably close time estimate for the ARCHES and PANELS files. The choice is.spend more time carving at the start or spend more time sanding at the end. I find anything over 8% leaves more undesirable visible lines than lower settings and requires a little more sanding. I prefer a 6% stepover for Finish Toolpaths, but often compromise and use 8% to save time. So, you'll see the front panel carving has a 39% stepover for the Roughing Toolpath (using a Down-Cut 0.25" EM 2 inches per second Feed Rate and 1 inch per second Plunge Rate) and 8% stepover for the Finish Pass (using a 0.0625" Tapered BN 3 inches per second Feed Rate and 2 inches per second Plunge Rate). The files I created for the project already have the stepover percentages set just as I used for creating the sample. I don't always keep track of actual machining time, but in this case, I did. Oh, and about how long is your finish pass taking to complete? With my 1/8 it took about 3 hours, I just recalculated and it's 10hrs! My 1/8" bit actually did a much better job so I must have got something off and step-over is the only thing I think I'm missing.
