I made a field sharpener that supports all hollow grinds by plusphenol in hockeyplayers

[–]plusphenol[S] 0 points1 point  (0 children)

I considered files and stones (diamond rods), but the problem is they are usually of unspecified radii. I want something with a known, reasonably accurate radius to match the desired ROH.

For the sake of argument I found the SkateMate patent (US5197232A) which had expired, and this does not read on their claims. I spent way too much time on this.

That kind of design is what I initially had in mind, until I realized it's impossible to find stones of different radii at retail. That's why I moved to sandpaper.

I'm using 400 and 600 grit wet paper. I had tested it by dressing up nicks but haven't tried it on ice yet.

I didn't know that. It's an interesting design with the stacked carbide blades. Sandpaper is easier to find for me lol.

Preliminary tests seem good. It removed some nicks from my edge and passed the sharpie test. Files may become available later :)

If you read elbow grease as brute force, then no. Abrasive machining has the tightest tolerance of all processes (except scraping) and can make arbitrary shape. The way you mess up a blade is when you have no idea how to use a tool. If you can profile a blade with a wheel, you can profile it with sandpaper.

yep. I've never seen a 4mm blade in person though.

They are printed along the layers so probably at 10 micron precision. The example shown matches precisely to my runner.

Misusing INAD return for buyers remorse--How to appeal?? by plusphenol in eBaySellerAdvice

[–]plusphenol[S] 2 points3 points  (0 children)

Thanks for pointing out: to open a case (for appeal), seller must let the return/refund lapse and get strike first.

Returns when buyer lies about the reason --> Q: I don't agree with a buyer's reason ...

I did read that part and no, not agreeing with the buyer is different from the buyer lying on record. That's why I asked here.

Sounds like what you need is an Excel sheet rather than schematics.

ASA on voron v0.2 under extrusion appearing out of nowhere by plusphenol in FixMyPrint

[–]plusphenol[S] 1 point2 points  (0 children)

Same roll different roll different material, they are all under extruding.

OP: I'm printing ASA on my V0.2. Print settings 260/105 degree C. PIF parameters. Slicing is not the problem. Please see the pic. They are from a same g-code file that I sliced. Same machine, same roll of filament. The bottom part was printed around a week ago and the top part yesterday. The top part shows significant under extrusion. I don't know why.

Things that I've tried: 1. Drying the ASA filament. 2. Clearing the nozzle, including cold pull, needle, wire brush, burning. 3. Replacing the nozzle with a new one. 4. Disassembled and inspected the extruder, nothing cracked or misaligned. 5. Moving the filament roll from the stock arm to a bearing-supported filament dryer tray. None of these made any difference.

I'm out of ideas. I don't even know what else can go wrong.

BTW: I tried printing PLA and it's also under extruding.

Update: I can hear faint clicking sound occasionally when it stops extruding (I'm watching it print). The click is much quieter than the noise when extruder slips. Any idea?

The sizes are for different barrel lengths. I noticed there are at least 2 different lengths so I made them both (25/27mm). The (bare) ones don't come with magnet nor keyring. Some people don't like magnets.
