This is the next Asian inspired Yin/Yang piece. Two dragons. If any of you guys wish to cut these for yourself, IM me with your contact info and I will send you the Vectric Aspire project files.

That’s a really nice engraving Rob.

Thi is also MDF?

Very nice, BTW!

Continue to be amazed Rob! I can’t see your scan lines, the pockets are crazy accurate and finely detailed.
How many hours did this run? How many tool changes?

@Alex_Paverman Yes it is mdf. Ill be sticking to that till Ive mastered it. then I will delve into other materials.

@Brandon_Satterfield Thanks for the complements. ! tool change. 1/8" ball mill and 1/4" ball mills. I was running the machine at around 200 in/min and had some issues then slowed things down to 150 in/min and no more issues. final cut took about 5hrs. roughing about 3hrs.
I got around the x or y raster lines by using an expanding round cut pattern rather than raster cut on finish pass. However I did use raster for the roughing passes. These options are available in Vectric Aspire v.9, which is what I use.

Absolutely stunning! Scroll saw to cut it out? or CNC?

I anvy you @BuddahrobSidartha_Ro ​! I cannot go faster than 1500-1700 mm/min…
But what rpm are you using at yours 150inch/min?
I really wanted to try a model of your kind but all my MDF carvings made have a ‘hairy’ look which I cant’t get rid of. Because of this all thse fine details are lost. I didn’ succeded yet to find a valid postprocessing method for this issue…

I have set a limit of 1200mm/in. I seem to have to fight with the screw tensions less now I am running slower.

@Colin_Kaminski ​, it appears I am not alone… Max I can ‘touch’ is 2500 but it’s not reliable… Anytime can appear ‘lost’ steps. And for a 5hours job this would be suicidal

@Alex_Paverman I was able to fix the lost steps by bumping up the servo power on the tinyg but the screws still got loose.

@Colin_Kaminski ​ ‘bumping up’ us meaning what?! I pushed the current 25% over the rating and the steppers are already so hot. I had to install coolers.

@Alex_Paverman , Wow, my steppers are cool and I am about 1/8 turn over recommended. Did you set the tinyg settings as the limit? It the CAM? I also have very little tension on the adjustable ACME blocks. But, the stepper motors heat mostly while still. @Brandon_Satterfield do you have any advice for us?

@Jeb_Campbell The cutout was done with a profile toolpath to .800". Im ok with cutting into the wasteboard.
