- We built this new guy from the ground up to help bolster our manufacturing operation. I'll take you through it top to bottom, front to back, we look at its features and how it was built in detail. I'll take you through all the systems, and review how it is working for us. We design and build in a method you have seen in our last build. This fully contained machine has a number of new features to make our lives a little easier.

We have about 350 hours on it so far and will also include a performance review of the design.
Enjoy!

If you wanted to add dust collection, having a replacement pan for the bottom and an air return port at the top would be pretty nice. Then the air will blow dust downward towards the collection, also keeping dust off the linear rails.
Dust collection is always a good idea in something with potentially explosive dust.
I see alot of these diy cnc builds on CZcams and they share a common issue. They use the spindle with a collet built in. I would say spend the extra $500 for an spindle with iso20 tool holder. Even if you don't use an ATC you get toolless, fast and easy tool changes.
But otherwise awesome build. I really appreciate the packaging for compactness. Not easy and makes the machine much more impressive to me.
Agree, but more like $1000 to $2000 extra though !
Especially if you allow for ATC later in the design
We will likely be adding a complete tool changer eventually, and thought we'd wait until then for a really nice spindle. For the time being, you can't beat this simpler guys for the price (around $500.00) but I completely agree that it is worth the extra money for something that simplifies the tool changes, especially if you are running operation that requires a lot of them. We change tools once in an hour and a half, so it was not as important to us as some of the other upgrades to this design. Thanks for watching and the comment!
true, but id go bt30, more options for tooling
but these spindles are 1.8k to 2.5k, i gut my current er16 spindle for around 300€ so BIG DIFFERENCE but yeah certanly cool
Just chuck the stepper and go servo. Been down the same road but once you get used to the speed, performance, reliability and low noise you get from servo you will never look back again
but is tuning for a entry level cnc machinist as difficult as I have read?
@@T0tenkampfNo it’s not, most servo drives have good tuning software. If the servo doesn’t have it buy one that has.
very inspiring tour of your product!
Thank you for showing this. Great work.
Thank you, that is very kind.
This is a fantastic design!
Brilliant work!
Thanks for watching!
Hello , nice small footprint machine!
I see two things to improve.
1) Make cover to timing belt inside enclosure especially that I don't see you use safety relays and door switches
2) revert fans. Top fan should be exhaust and bottom fresh air supply
Excellent work !
Thank you!
Clean!
Thank you, much appreciated!
awesome !
Thank you, very kind!
amazing
Thanks for taking the time to watch!
With a bit of googling, I think I understand what the product is (because of the parent company, hint for the others: it's actually what's shown), if I'm right, I'm surprised that there is a economic case to be made for a custom CNC.
Excellent work, and thank you for showing everything, it's a precious public education service you are providing. I was suprised by the lack of bellow on the Y axis, but even that has been answered (no space left on device). Great work.
Thanks for that, yes ultimately we want to sell machines and or kits (that's why the website exists) but we need to work out all the little kinks before we do that. I believe very strongly in transparency so I want people to know exactly how it's made and what's wrong with it, and what we'll do better on the next one. That comes from us subjecting them to extensive use, with no one to blame but ourselves when they don't work right.
I also what people to know that even if your jumping into the water, making a product or providing a service, that there are avenues to do that. Industrial grade CNC's are still pricey, but you can build them yourself as good as a lot of what's out there, with the added benefit of designing them specific to your needs, and I'll do my best to show how we go about it.
Can you post a diagram of z axis cylinder lift and how it plumbed
Very nice! I wonder i& you could not have achieved same/similar Z axis speed with springs instead of complicated fluid cylinders. But nice regardless!
Have you tried using larger 1:1 pulleys? The belts should have more leverage at a larger radius so the stretching should be less significant and not affect surface finish as much
HI there, not yet, I have ordered some, I don't remember but I thought I talked about that in the video. I just threw on the pulleys I had that worked for the time being when we switched from a 2:1 overdrive.
Do you have a hardware list of the components you used with make and model. That you are willing to share. Thank you for your help in advance.
You make your CNC frames using steel sheets. Do you flatten these sheets before using them or do they come flat out of the factory?
their website claims a "physical tolerance" of .5mm (my sweet lord that's rough) so apparently no post-weld stress relief/machining or other accurizing process is involved
@@brianwilliams1094 Yeah 0.5mm is a lot. I think they calibrate the rails at the end by steel shims or something.
Awesome build, I can see a lot of time and thought went into it. Not sure why you bothered with steppers though. chinese ac servos are so cheap these days that there isn't much savings by going with closed loop steppers. A couple of 400w ac servos and that thing would fly
Thanks! Yeah it's time to try something different, I only have been using these because I am familiar with them, but the next build will definitely have servos.
@DIVCNC it's definitely a different ball game to setup, a lot more variables to consider when tuning, but I will say the matched sets you can get have some rather good preset settings that get you super close. Believe it or not i have a lathe running a pair of lichuan 750w ac servos that have the factory settings. No oscillating, minimal lag and some decent performance in the acceleration department. Having experience matching servo motors to new drives/amplifiers i can assure you this is surprisingly good. Starting from scratch can be a pain.
Keep up the good work 👏 🙌 👍 👌
Clearpath Servos work quite well with the Masso unit, ask me how I know this or check out Pele' on my channel. Nice builds BTW as soon as I add on to the shop I am going to do a 5x10 router table build..
Question for you what pressure you run on you air manifold and do the Capri blow guns hold up to it? The new Harbor freights are only rated to 90 psi and leak with the 135 psi on my manifold.
Great work! Can you provide the blueprint to the CNC to build a similar one?
Hi Valentin, we are not giving away the files just yet. We will refine the design and then release them in one way or another. Thanks for the compliment and your interest!
@@DIVCNC great to hear that they are coming ;) looking forward.
I rather have this than a tormach... Only thing I didnt like was the wiring; lack of identifiers and no crimp ferrules on the wires inserted into connectors
You had your X and Y axis mixed up when you were explaining it and saying that the head moves on Y 😂
It's a goofy reason, but the first machine I built 7 years ago, I set it up that way with the head moving as the Y-axis. I did it so the jog buttons in Mach 3 matched the directional movements of the machine relative to the position of the control panel. It made the machine more intuitive for a novice user. Now I set up all our machines that way just for continuity in our programs, so any machine can run the same code. I can switch them over, but I would have to switch all our machines and remake code for about 40 different products haha
@@DIVCNC I totally get it, on a traditional C frame style mill I was always told to imagine the spindle moving when writing code, but when I would jog the table it would be opposite and I would get confused sometimes. I have a converted PM728VT with mach 4 so I know what you mean. You’re probably just used to saying your head moves on Y axis.
Good luck learning out of it when getting a real industrial cnc machine. Not so cheap to crash as the hobby toy machines.
