pretty cool
good job keep it up.
Nicely Done. What Stepper Drivers are you using? What microstepping level are you at ?
I'm using an mx4660 for a Mach interface and running at 54vdc. Micro steps are I think 8.
Hi, Pretty awesome speeds, congrats on setting it up so nicely. Mine is a little slower at the moment but we haven't finish yet. :) What exact dust boot did you add to it? Was it a perfect fit? I'm looking at getting one from Aliexpress that looks pretty much like this. Does it unclick easily for a tool change? Oh and one more question: Do you find the 2 1/2" hose to be adequately removing all the dust and chips while operating the machine? I'm asking as I'm still on the fence deciding if I need the 4" hose or I can go with the narrower one.
Thank you! I definitely do not run this fast all the time. The dust boot is from Daedalus DIY CNC. I did have to 3d print a bushing to offset the boot from the spindle. The 2 1/2" hose is adequate but it is running on a Festool extractor. I use a 4" hose on the same style boot with a dust collector on my Avid machine.

@@CNCMakerNW I thought so. But it's still amazing that you managed to set it up in a way that it can do so rapid movements without binding. I spent weeks fine tuning mine and it still stuttered and stuck at certain speeds that were slower than yours. I eventually decreased the speed as I could probably spend a lot more weeks without much more success. So good work with that.
Did you need to print a bushing to narrow the dust boot part that is then placed between the spindle and the Z axis C-beam? Same as what this fella is talking about here: ua-cam.com/video/hVexDVCLLpE/v-deo.html?
I have a 2hp Chinese dust collector. Do you think that could handle the collection at 2 1/2" or you would go directly to 4" with anything likely less powerful than a Festool extractor?
@@AdamBaranyai You have exactly the right idea on the bushing. I used a PETG 3d print instead of wood. It took about 10 minutes in Fusion 360 to design. Clearly either one would work just fine.
The binding is frustrating for sure. I wish the best on that journey.
Dust collector milage varies a lot. I only use the 2.5" hose because I'm using the Festool. When using the dust collector one will nearly always be best served with the largest hose that can route to the tool. My rule of thumb is to match the collection duct size as close to the tool as possible.
@@CNCMakerNW Thank you. For now I'll leave it as it is. At least it works and I'm brand new to CNCs so there's a lot of other areas to work on before I can make my first cut with my Ultimate Bee.
I think I'll try with the 2.5" hose and if it won't be enough, I'll replace it with the 4".
Would you mind sharing the .stl file for the bushing? I don't (yet) have a 3Dprinter but one of my colleagues could print me this bushing. It would be great to upgrade to this dust boot but my Fusion 360 knowledge is also very limited at the moment so I could only make the bushing out of timber at the moment. That is not the best material for this project I believe.
Loving your ultimate Bee.... Would you be able to show me how easily your limit switches for to this machine, and maybe what you think the best ones are and how to fir them to the extrusionsetc?
Hello, and thanks for watching! Here are the switches I used. a.co/d/ejSzlah and here are the pieces I used for brackets. I added an m5 bolt and slide nut to mount them to the extrusion. The software and wiring will depend entirely upon your choice of controller hardware.
is this z axis is strong enough to cut aluminium material?

How fast do you have it moving here? Also do you find that the 12mm ballscrews are undersized? I’ve seen talk about “whipping” at higher speeds? ( I think bulkman recommends not to rapid over 250ipm maybe)? Don’t quote me on that.
I’m really wanting to pull the trigger on a 1500x1500 ultimate bee with the smaller 1.5kw water cooled spindle. Lookin to cut strictly .125” or thinner aluminum sheets.
I plan on getting the servos when I order.
Any advise?
It's going 6000mm/min or 236 inches/min. Ball screw size is not an issue at all at any speed this machine can run. I have no experience with the servo motors, I'd love to hear what kind of results you get with them. Also, if all you're going to cut is 1/8 nch aluminum sheets, I don't think that the flex from the one and a half meter crossbar on the gantry will hurt you too much. Especially not with the 1.5 kW spindle.
@@CNCMakerNW thanks for responding! I look forward to seeing more vids of the ultimate bee as well as your Avid.
Hi 👋 like to know how is your settling on your mach4 ..I have the same machine if you don't mind ..thank you
Which Mach 4 settings are you looking for? Specifically for this test I ran 10000mm/min @ 1000mm/sec²
Hello ,any downside for this machine? Can you tell me more from your experience? I want to buy one similar.Thank you
I am currently making a thorough overview of the mechanics of this machine with pros and cons.
@@CNCMakerNW ok,i'm waiting to publish
@@CNCMakerNW I'd really be interested in the z axis. That is, is there any flex or "tipping/nodding" of the spindle motor. This seems to be about the only weak point with these kits.
@@STidrvr There is noticeable nose dip on this machine compared to my Avid, especially. I plan to do a more in depth comparison video in the future.
