Itd shown in mm as well, is that perhaps what you are seeing? Post screenshots or sample files Also, make sure your CAD file is sized correctly
Sorry, "ltd"? CAD is definitely correct. See attached file. The large one should be 4" diameter. Oddly enough, it appears correct when it is sent directly to CONTROL through the CAM "Connection" window. But I'm working off a server, so I can't actually use that "send" feature for production.
Typo "its" S and D next to each other on keyboard. Glad you are up and running Sounds interesting, care to share?
I design at my nice clean warm comfy office computer. All files are saved to Dropbox and then accessed from my CNC laptop in my cold dusty workshop
Ahhh OK sounded like you were developing something gotcha now - you can still keep a copy of CONTROL on your design PC just to check/sim - the viewer in CONTROL is a little different from the one in CAM
If only browsers would just allow connections to IPs (; CAM running in the cloud, on github.io, served over https: 1) Try a connection to CONTROL over https - fails because cert is invalid. Cannot generate a publicly signed certificate for IPs, cannot allow self-signed certificates in a ajax call (doesn't prompt to add cert to browser store) 2) Try a connection to CONTROL over http, to port 3000 at a local IP: It's a good thing, but indeed inconvenient to us. Even to reach localhost, we have to: Host a public DNS entry: mymachine.openbuilds.com -> 127.0.0.1 Include a public certificate / private key for mymachine.openbuilds.com in CONTROL Just so the browser can do a https connection, to localhost, with a valid cert that matches the URL. If there was any other easy way for a browser to make a call to CONTROL, we'd have had an IP entry field long ago. Four, five years ago you could, we had a IP scanner built into LaserWeb2 back in the day (; - used WebRTC to find the local subnet, ran a scan, found instances to connect to. Was awesome. Then the security guys closed all that up.
I use a Raspberry Pi on a converted vertical bench mill out in the garage, I wrote a proxy to relay from CAM to the Pi. I get its ip and use static DNS so I can use mypi.openbuilds.com with your certs 8^) I even intercept the /activate call and pop a local browser so it makes it pretty transparent Code: const staticLookup = (ip, v) => (hostname, opts, cb) => cb(null, ip, v || 4) const staticDnsAgent = (scheme, ip) => new require(scheme).Agent({keepAlive: true, lookup: staticLookup(ip)}) var options = { hostname: 'mypi.openbuilds.com', port: https_port, path: client_req.url, method: client_req.method, headers: client_req.headers, agent: staticDnsAgent('https', mypi) };
The problem is still that the user needs to have the proxy installed. What we're talking about is browser on PC1 > ajax call to Node instance on PC2
Of course, if the user really didn't have any other way to get the file across, there's always "/upload" (CONTROL instance on other PC's IP:3000/upload)
Use Shopbots at school, Use VCarve... Unfortunately cannot get the shopbot VCarve version to write the GCode file. so Im trying to learn how to use this for my new Lead 1515.. Love the configuration.... Trying to import a DXF. saved from Solidworks in several different formats.... including the polyline version of R14 and R13 and R12... still not right. This is what I always get. Take a guess what its doing. Was able to move the origin without problems... but that radius on the Left.... you guessed it should be an internal radius.
Post the DXF so we can tell you whats wrong with it. But basically, see docs:software:file-errors [OpenBuilds Documentation] Also, see Vectric Post: docs:software:vectric [OpenBuilds Documentation]
Late last night I found that my version of vcarve would read the dxf and allow me to join the vectors then re-save it as a DXF... When I did that I was able to read it in to Openbuilds CAM to define the tool paths .... Haven't cut parts yet but I ran a simulation.... And it's looking like it should work... Also working on trying to add the Openbuilds Post processors to my edition of vcarve we'll see what I get.
I thought the OpenBuilds post processors were already available in Vcarve. I have it and do not remember loading them, but selecting from their list. But I could be wrong.
Only from v10.5x somewhere onward, people running older versions can grab them from docs:software:vectric [OpenBuilds Documentation] - simply copy into the PostP folder: Where do I look to find the Post Processors folder on my PC?
Oh. That makes sense. I recently updated Vcarve again and added used Openbuilds post processor for cutting 3D reliefs on my main CNC. Everything I had done prior was with a post processor designed for grbl based rotary 3D carving so I had not checked when I had the older versions of Vcarve.
Nested Object: It seems sporadic when I select an area I wish to laser cut using Raster whether the internal Objects get ignored and included in the fill or if they are left un touched. I have converted the image to a few different formats with no obvious voids in the inner object that would make it appear as not enclosed. So as a test I have even tried to draw two simple circles using the tools in the OB CAM and tried to only Raster Fill the outer Donut. These should be Totally enclosed and still I can not cut a donut. How can I manually apply a mask for the area I wish not to be Lasered? I have even Opened the Hello World Laser example and tried to recreate the Paths using the OB CAM software. But Can not seem to select the enclosed areas.
I found that I need to Select both objects and the Raster will respect the inner bounds. Its funny though because at times the algorithm does find inner objects and doesn't fill with raster.
Is it OK to suggest features on this thread? If not please move or remove! I'd LOVE to be able so save toolpaths presets ... or to be able remove generated toolpaths while keeping toolpath settings ... or to be able to create a toolpath with no geometry pre-selected (in which case I'd just save an empty workspace with my own toolpaths) Use case, I do most my cad in Illustrator/Affinity an import SVGs into CAM. Having presets for my usual bit settings would be a great timesaver Just my 0.02 Have a great day!
I'm having some issues with bringing in a dxf file into the OpenBuilds Cam software. The software will say please wait parsing documents. After a few seconds it will have a message that says the page is unresponsive and ask me if I want to wait. After getting that message 2 or 3 times it will eventually switch to a web page that says error code out of memory. Exactly how much ram do I need? The file is only 1346kb.
Depends on the complexity of the DXF, PC specs, and also what the entities inside the DXF are (please convert everything to PolyLines and Save as DXF R14 format for best performance) You can include the file if you want us to check specifically whats wrong with it
Thank you for your response I have attached the file that I am working with. What do you mean by convert it to polylines? I am fairly new at this so please be patient.
Opened the file in nanoCAD and it looked like it was made out of blocks (and many many objects), opened it in inkscape and it crashed.. opened in Estlcam and had no problems. Cheers Gary
Estlcam works well for me too. Like Gary, it opened up for me and I had no issue creating tool paths. Estlcam was well worth the $59 license (You can try it for free for as long as you like) and tool path generation is very similar to Openbuilds CAM. As for the "k" file, I hoped to have a solution for you as I started writing this and taking the screen shots. In the end it failed so I opened it in Fusion360 and it looked "odd." Only two of the entities appear to be "closed" (shaded blue indicates this).
Thanks for looking at it, I got it off of Etsy. My wife saw it and challenged me to justify my cnc machine lol. Would I be better off just attempting to create it myself at this point?
What are you trying to do, simple engrave or v-carve? you could download free Estlcam and try it or ask somebody to clean up the file, was it an svg or jpg first? Cheers Gary
It came with a DXF, PNG, PDF, and SVG. She would like that K raised with a 3/8" border on an 8X8 piece of hardwood. Essentially all of the negative space needs to be one large pocket. I started with the DXF file because it is the only way that I know how to do it, and that doesn't seem to be working out for me. I downloaded Estlcam and will give it a shot. Thank you for your help.
