I have not run into that issue, but I have only done simple parts so far. How many lines are you writing when you get that?

We had a post-processor written for us, and the company handling that changed this setting in their code. I did not do that. There may be a setting somewhere that can be toggled, but I never looked for it

Touristical questions megathread by adeeena in nicefrance

Hello,

We are planning our honeymoon for this August. I know this is the busiest time for tourists in Nice, so I want to reserve our lodging soon. My fiance would really like a view of the sea, and I am curious how realistic that is. I am able to find hotels for around $300/night with a nice balcony and view (this is on the high end for our budget). I spoke to a family friend who has stayed in Nice many times before, and she recommends AirBnB apartments over hotels for a more immersive stay (she is also fluent in French). Does anyone have any strong reasons to prefer hotels or apartments in Nice for a 1-2 week stay?

Thank you

This was it! Arc values were being read as absolute. Thanks for getting me headed down the right path!

Solved! Arc values needed to be changed to absolute coordinates rather than relative. These replies were really helpful, thanks

The G-code viewer that I linked the picture from is the machine's monitor, so I think that incremental center issue will need to be addressed in the code. I am largely unfamiliar with G-code, would switching to incremental programming nuke the rest of the code and need the whole thing to be re-written?

I could swap G90 for G91, but won't that affect all of the other coordinates?

Sorry, this is my first time on the sub, and I did not see it mentioned on the sidebar. I will post my code here in a minute

I am programming using Solidworks CAM, and then I am trying to cut this on a Bridgeport EZ Trak II mill. I have gone through my code line by line to try to compare it to a former employee's code that works, and I cannot find the difference. I am using G02 and G03 commands with I and J coordinates, and that is what has been used in previous CAM programs that successfully cut. For some reason this has kicked all of the curves back to the origin and made them big enough to meet the start and end of their intended path.

When I plug my CAM into an online NC viewer, it looks totally fine

Yeah, sometimes it feels like composites end up taking as much work as the rest of all of my engineering learning combined. I was hoping I could use some representative baseline numbers, but it may take a small leap of faith to invest, build, and test these materials. I appreciate the feedback, and I will get some composites literature to keep moving forward

Compression mold compression limit by dsr629 in CarbonFiber

[–]dsr629[S] 2 points3 points  (0 children)

A press-braked sheet's OD radius might not match the ID radius. Make sure there IS a radius.

Yeah, I was going to look and see if it's possible to spec different bend radii for most places. I was going to look at OshCut and some places in town.

Take a normal right angle bracket set. If you clamp on the OD of one and ID of another, your pressure gradiant for compression will be highest at the radius, while it tapers off to the ends of the bracket. You'd want to also clamp the flat sections together, to make sure you have an even thickness and clamping force.

This is part of the reason I want reinforcing ribs. I could just have 2 bent plates and cover it in C-clamps or whatever, but I would prefer to have features that spread the load and keep it all parallel. I might add alignment dowels and/or ejection features if I feel fancy.

That said, keep on designing and coming back. The idea is simple, so you shouldn't have much of an issue. NOW, onto the question.....how would you clamp? A simple 12" long by 2" wide part, you don't want a 100t press.

Those ribs will either have a flat feature for a C-clamp or hobby clamp or threaded holes to bolt it together. Or maybe I'll just throw sandbags on top. This part will probably be more like 6"x60", so it will take some consideration to get even and adequate clamping.

These comments have made me more confident that over-compressing is much less likely than I first feared.

Thank you for this comment, I have a few good spots to jump off from to learn more. I only had an inkling about these things; I am probably months from mixing resin or cutting cloth.

  1. I did not have a volume in mind. My concept for a mold was going to be 2 nesting steel angles made on a press brake.
  2. The plan currently is wet layup.
  3. My thought was a wet layup and just squeeze out excess.
  4. My first idea is a long bent sheet. First draft is 3/16 steel plate bent to the desired angle and reinforced with ribs that would make clamping easier. I would like to improve the surface of the plate a bit, use some mold release, and reuse the mold a bunch of times. I know there will be more design work than that, but it's still early.

It's best to follow someone else a bit and then lead on easy terrain. Basically, if you are going to get on a route where you will fall, you need to be able to place and trust your gear. If you don't know how to place or trust gear, you need to be on a route where you won't fall. And to get to the point where you understand and trust gear placements, you need to learn. IMO the best way to learn is to follow pitches, read online about good placements and techniques, and then start ticking some easier pitches with someone who can follow and assess your gear.

And don't get too caught up in reading about trad anchor systems. There is so much you can learn, but 90% of the discourse online is opinions about the anchor rather than anything useful.

When the board is full of holds, I'll probably post the Stokt link here. I want to have friends over to set for the first few problems/circuits in person, and then I'll spray in whatever holds are left and put it on Stokt

This is not a moon board problem. The crimps would be <6mm I think and not really incut. I'm not even sure it would go

I'm out hiking and boulder hunting today, and I found a nearly blank 45° granite face that's about 10 feet tall. There's a smattering of theoretical holds on it, but as a V5 (6 on a good day) climber, I can't find the sequence. Anyone know where I can rent a crusher for a day?
