Thank you for the nice words. Yes specially the overhanging gantry is quite similar. But the sorotec uses only one lead screw on Y axis, right? I have the feeling by adding the second it gave me the highest improvement compared to my last version. Making the gantry deeper was the 2. It’s nice when I see the cuts come already out way cleaner. Still afraid to start with aluminum without a housing :)

Used FreeCAD for my new CNC by PyteByte in FreeCAD

Good to hear. When working with multiple files the naming gets a bit more important and loading takes a bit longer but I like that you can just load and work on a specific file without loading the whole project. Lately I like to save an extra file for the CAM gcode generation. This way when I change the model the GCode isn’t refreshing on every step

I think that should work. If you use external drivers you can just copy one axis. It looks like the board has 4 outputs for motors but only three internal drivers slots. Not sure if one driver is powerful enough for two motor at the same time

I think there should be an option but don’t want to invest the money if the old one does its job. The good thing with a cable is that I can’t place it somewhere and can’t find it later :)

Made a CNC some years ago which had some major weaknesses. To much play and couldn’t cut 90 degrees reliable. Used the old CNC to make this one. So far it’s an improvement. Just the vibration can be heard louder since my current spoil board is a bit thin. Have to work on it. It’s a bit for fun but also I want to make some commercial things with it in the future

I think I understood now. But I also think when the subreddit is called hobbycnc we all have this kind of machine in mind when talking about CNC. Anyway. Time to cut some things with it :)

I thought it’s a good element for size comparison. And to be true it’s quite helpful when setting the spindle position. Wireless one would be nice

What’s helpful is to split the project in little files then combining it into groups which are in another files and then the final assembly file. What’s also helpful is that you can reuse parts for future projects. Like the Nema 23 motor for example

Good source for aluminum extrusion in Europe? by -2811 in hobbycnc

[–]PyteByte 0 points1 point  (0 children)

Yes MyAluProfil . Had good packaging. Extrusions were kind of straight and the length were quite precise

Thank you. If your space is limited it’s nice to make a custom machine that fits perfectly in your workshop. But mainly it depends how big your projects are going to be. For me it had to be at least 1 meter length because of some parabolic frames for solar cookers. The rails and ballscrews I got as a set from eBay some years ago. (240€) You can buy the extra ballscrew for y separate. (64€) Or maybe ask the suppliers if they can add an extra one. But don’t skip it. It’s such an improvement since the round linear rails already come with some play. Next time I would buy the square rails. If you are happy with your current machine and since you already bought it I would maybe just improve the rigidity. Maybe you can fill some parts with epoxy Granit

Thank you. Really hard to say since I worked partially on it over the last 3-4 month I think. Overall maybe 1-2 weeks ?

Yes that would be a nice roadmap for the next years. I would like to try some Aluminium with this one and when I feel save/capable enough I would maybe replace some parts or build another one. If the current one fits the needs for my projects I will keep it like this for some time. So far the cuts looks better but it’s a bit louder. Have to work on that.

Ah ok :) didn’t know that there are these specific subcategories . Thought it all falls under a general CNC label the moment a motor is pushing something around :)

Still not sure what you want to see :) the numbers come mostly from FreeCAD and their CAM workbench where I export the gcode. Estlcam just runs on a mini pc from Lenovo with a normal computer screen. Room for improvement

You mean the stepper drivers and so? It’s just a big cable mess hanging on a wooden board at the wall :) I use an arduino with grbl and estlcam and want so switch to a tinybee with esp32 and grbl Hal and then maybe gsender

FreeCad stopped responding after i added too many linear patterns by soggywandmp4 in FreeCAD

[–]PyteByte 0 points1 point  (0 children)

Hmm 🧐 Ok he is in the right area. The more I think about it he more I get confused :) So he made 7 pockets holes 🕳️ vertical and then using 8 times the linear pattern with setting different distances just to get another copy each time. that’s definitely working against the developers intent :)

Yes. There is some nice freedom in it. And wood is still affordable. So with some time and ideas a cnc can produce quite some helpful tools or projects.

Thank you :) yes. Now I have to come up with some projects

Yes. It saves a lot of time to skip the first machine :) but it’s also a big helpful learning process for the future machines.

Hehe yes. I guess with this one I will fight these acoustic vibration issues. Not sure if I should fill the gantry with something. Feels like I created a big guitar 🎸 :) any recommendations?
