Set up your CNC for Vertical Cutting: New vertical stand design
Вставка
- Опубліковано 23 чер 2020
- In this video, Chris shows off how you can mount your CNC vertically with his stand-alone stand design as well as what sort of performance the LongMill will bring in this orientation. He also reflects on the things to watch out for if you are considering a vertical CNC setup.
The stand design shown in this video can be found here for download (includes both 3D models and a part drawing): cad.onshape.com/documents/93f...

**One very important thing I failed to mention in this video is that the two EEPROM setting I changed were $111=3000 and $1=255. This slows down the maximum feed rate on the Y-axis to ensure that I don't lose steps even on a longer job and also tells the motors to hold their position as long as power is being supplied to the machine. If you don't set $1 to 255 then your machine may be heavy enough to overcome the mechanical advantage of the lead screws and will slowly 'fall' downwards, losing whatever position it was originally in.
This is a re-upload of the video from two days ago. The intent is to instead split the original video up into two distinct ones: one for the vertical stand and the other as a CAMLab relief tutorial, just to make things a little more simple and keep each video to a specific topic.
I will post the link to the CAMLab-only version once it's done

one could also try adding constant force "springs" to the Y axis to counter act the force of gravity. what is the weight of the entire Y axis assmbly including router? I'd guess around 28 lbs 20 two 14 lb springs one on each side might work. www.mcmaster.com/constant-force-springs
Yeah, that would work well to reduce the extra forces. 28lbs is quite accurate for the weight of the X and Y axes combined
A very simple counter-weight on a pully-system attached to the vertical axis (on the back side) could counteract the vertical weight and minimize the possible wear and problems associated with the vertical orientation. Something to think about...
wall mount with a hinge to angle it in and out would take up even less space
Newbie looking at 4X4 machines and tight on space. Wondering if I modified your design if CNC be rotated 90 degrees/horizontal - so that long pieces can be fed horizontally?
Yes, technically you could do that. Perhaps one thing I would suggest to is to get the Y axis dust shields to keep the dust from collecting on the rail and screws, but otherwise should generally be the same concept.
Any plans on this for Altmill?
Not immediately, but perhaps in the future! Thanks for asking!
this looks similar to rs32-cnc french open source cnc design
I suppose it has some similarities in concept. This design is an extension on our original open-source Mill One design that we first released in 2016 :)
Is there any reason to do this? Not being snarky, I just am not sure what the benefit of doing this is.
People would primarily choose to do it for space saving since it otherwise comes with some other downsides like machine wear and material loading
WHAT ABOUT THE DUST WE WILL BE BREATHING. SOLVE THAT. I am working on it. Beat me to it? God bless.
All our machines have options for a dust shoe accessory that will capture dust before it gets airborne and give your lungs better protection. We still recommend using breathing protection though to be extra safe, no matter what woodworking tool you use
