Excellent you shrouded the acme gears to prevent sworf buildup! VERY IMPRESSED with your ingenuity, skill and determination!

Joerg, as always there's just one thing to say: excellent work. Really like your work.

Great work on the cinematography. I especially enjoyed the bolt filing shot with the background flare. Beautiful.

The DRO was pretty clever

Nice idea for the handheld controller and nice editing ! Keep up the good work !

Such a great series. Very inspiring. I feel like your pedestal drill will become very lonely now your VMC is in action. Well done!

Amazing work! Thank you for sharing it!

Very nicely done great job can't wait for an update!!!

Un grandioso trabajo!!!! Felicitaciones!

I love the videos, they are great and offer a lot of insight on how to plan a build like this. I wish you had more details on your site about part selection for electronics etc.

Hammer Sache Joerg!

like your projects!

very very work..thanks for you time

Good Work 👍 Now I also want to build myself a CNC 😅

Hello friend. Great video. Good job. Thanks your upload video.

Good to hear! For my personal work I only use linux. Sadly for my professional work that's not possible. But ten years ago I wasn't able to use Linux even for my personal stuff. Things are changing, some open source tools are getting better and better, and some awesome commercial tools like davinci resolve are running just fine on Linux.

@@joergbeigang Yeah, from what I hear the VFX world has been making moves towards linux, especially since Apple hasn't been treating them too well. I watched more of your videos and your mill looks great. Personally, I have aspirations to make a mill using some sort of polymer concrete to fill in steel tubes and slots to give my future machine more mass and rigidity. Epoxy Granite looks interesting as well.

Hey there. Your project is great. i hope to see more of your work in future. I noticed that on Y axis you put home sensor so that it will be triggered when screw is close to it. Those proximity sensors are great (not affected by grease or dirt) but they work best only when solid metal flag is in front of them. (covers the area of sensor) If not all of the sensor head "feels" metal triggering distance might be uneven. Since allen screw that it should be triggered with, have hole in it, homing results might be inconsistent. I would recommend using hex screw without hole or reposition the sensor as on X axis (scissors type sensor positioning is more reliable) But maybe it works good for you application and my inner perfectionist is worried for no reason. Anyway thanks.

Thanks for your input. That was my first contact with those sensors. Therefore I didn't really know what I was doing ;-) I didn't measure the precision of the switches so far. But I'll do so. And I'll replace the screw as well.

there's end mills that cut in both directions called compression end mills made for laminate materials (such as plywood) so it doesn't fray like that

Для домашней мастерской очень хорошо. Только есть одна проблема "коэффициент температурного расширения". Слишком разные материалы, тут и углеродистая сталь и алюминий и полимерный бетон. При изменении температуры всё, это выгнет дугой, а после нескольких изменений температуры ослабнут винтовые соединения.

Awesome. I just watched the 8 videos of this series in a raw. I couldnt stop watching. The level of mechanical detail is superb in every single step and it is so well documented. The speed and quality of the footage is perfect. I can't understand why I didn't see this channel before. I got one question about assembly. After aligning every axis correctly and pouring the epoxy granite between the bed and the Z axis column, why did you loosen the metal blocks that were holding them together?

I'm happy you liked it. I loosened them to get the shims out. There was no need for the shims anymore and I liked to have them back in my feel gauge, where I borrowed them from.

Happy you like them. The dial gauge and the stand are some cheap Chinese ones. I'm pretty happy with my dial gauges, but the mount isn't stiff enough. At least for the gauge with 1/1000mm resolution. If I'd buy one again, I'll go for a proper one.

Inductive sensors are not mounted this way. The sensors are mounted under a straight account and not in parallel. The magnetic flux must be cut and not reflected.

Thanks. Had no experience with those sensors. Someone already pointed that out in the comments here. I'll keep an eye on the accuracy of the homing of y. In case I'll change it

Very nice, how accurate are those switches/can you link them?

For testing I moved the machine forward and backward about 1/100 millimeter. That worked well. For my purpose more then enough. They are acting exactly like a transistor. There are PNP and NPN versions. Shouldn't be too hard to link them. You'll need some resistors, and I used an optocoupler, because I'm feeding them with 12v.

Joerg, since now you have the mill operational for some time, any reflections on what you would do differently should you start another build?

@joergbeigang

Sure there are. The weakest point on my design is the connection of the column with the base. Now I'd would connect it with screws on four sides. Planned was just two sides, in the end I improvised with some steel in the rear side to get it stiff enough. And I'd make the whole column a little higher to have more travel in z direction. An other design issue that also concerns the column is the proportion. I didn't think about proportions of bodies in relation with their vibration behavior and resonance frequency. As closer the shape of a body comes to a sphere as better it is. Long and slim is the worst case. With that in mind if make the column quite a bit wider. Not that it's problem like it is now. The resonance frequency is pretty low and far away from everything the spindle is producing, but it wouldn't cost much to make it better. An other thing is the z assembly. This I'm planning to change in the future. Just not decided yet if I'll cast a epoxy granite block or if I go more in direction of a sk30 spindle. I think these are the biggest points.

Now it's a man in the middle approach. Works good so far. Only problem I got is that the library for the led display takes a bit of time to compute. So I had to lower the baud rate to 9600 baud. It's not a real problem, the buffer is always pretty much filled up on my machine, but it's "cosmetically" not nice. Also thought about giving the teensy a try.
