Description
Supercharge your CNC
The SuperLongBoard, or “SLB”, is an advanced, next-generation, plug-and-play, CNC controller for ALL GENERATIONS of the LongMill. The SLB allows your CNC to run faster and more reliably. We believe the SLB is the most significant upgrade in functionality and performance for all LongMills, past and present.
Each order will comes with:
- The SuperLongBoard in a robust aluminum enclosure with 4 mounting holes for screws sized #4 to #8
- Independent E-stop with 3 customizable action buttons
- 2.5m E-stop cable
- 1m USB-C to USB-A cable
- Mounting bracket, specifically for the Y-axis of a MK2/2.5 (not MK1)
The only other things you’ll need to provide are:
- Your own 24V 10A-12.5A power supply, we supply these and all past LongMills have shipped with one
- A CNC 😉
- Ethernet cable if you plan to use one
- For custom setups, the SLB ships with all 3.81mm green pluggable terminal connectors by default, plus we can include the 5.08mm connectors for connecting power and motors if you email us before ordering, but any remaining ones you’ll need to get yourself
The SLB creates a platform for our company to continue developing and bringing advanced features and improvements to the LongMill and other future CNC machines.
There are way too many updates and changes we’re bringing with the SLB to mention all of them, but we’ll continue to show functionality and answer questions as we get closer to production. For company updates in the meantime, keep an eye on our Blog or get news directly to your inbox by signing up.
FAQ
Q: When will the SLB ship?
A: The first round of SLBs have already shipped. Back-orered SLBs are expected to start shipping late May early June. We will continue to post updates on our Blog. To get news directly to your email inbox, feel free to subscribe to our mailing list.
Q: Can the SLB work on my LongMill?
A: The SLB is compatible with ALL LONGMILLS. No matter what size, generation, or version you have, the SLB will plug and play with existing LongMill hardware of all generations with minimal settings changes. We believe this will be one of the most substantial upgrades any LongMill can have, past or present!
Q: Will the SLB come default with the LongMill in the future?
A: Yes, starting with our new batch of MK2.5 LongMills the SLB will now ship standard with the machine. This also comes with an associated price increase to reflect the additional value we believe the SLB provides.
Q: Will the SLB work with my CNC?
A: If it’s a LongMill or AltMill then definitely it will. Otherwise, your CNC should be supported so long as it’s a typical hobby CNC setup with open-loop Nema 23s. As we roll out the SLB we’ll begin hearing back on other successful configurations and update this ‘Answer’ appropriately, since otherwise we can’t provide a definitive guarantee other than to say that it’s very likely to work for most hobby CNCs. Other machines that have been proven to work so far: Onefinity.
We’ve earnestly done our best to ensure the SLB would be ideal for any typical setup since the inspiration for the SLB came from trying to take things that are normally only available on more expensive and ‘closed’ boards and bring them into the open source domain and at a more affordable price for the benefit of as many hobbyists as we could. This means that although you will need to change certain settings to match your specific setup,the SLB will support a range of machines and accessories including 5/24V limit switches, touch plates, tool length sensors, laser diodes, external 4th axis, and more.
Q: What about if I want to use higher voltage or external motor drivers?
A: We do currently have another version of the SLB in the works that we’re calling SLB EXT since it’ll support much higher voltage and external motor drivers for closed loop support as well. This will extend even further SLB support for a broader range of machines and setups closer to production-level. This board will be what powers our AltMill CNC and you’ll be able to see more updates about it on our blog as we begin making deliveries.
Q: How can I know if the SLB is right for me?
A: There are many other offerings on the market that come with a wide range of features, simply put the choice between these will always come down to budget. If you don’t think you need the features offered by the SLB then it’d make more sense to spend less money. In this case consider getting a more typical grbl board or some of the newer x32 hobby CNC boards that might require more DIY setup time for wiring or programming. For instance the Blackbox x32 has the benefit of a direct wireless connection but less extensability. If instead you feel like you want to pull all the stops to support a higher-end CNC or use more advanced features then you might want to increase your budget and look into a Centroid, UCCNC, or Mach setup. We believe though that we’ve done our best to match the SLB up with the mid-level hobby CNC community where it makes sense to spend $150-200 on a controller to really unlock all the capabilities you’d be looking to expect out of your $1000-4000 CNC.
Q: Is the SLB open source?
A: Yes, the SLB, firmware, and related software like gSender will be released open source. This may come at a later date when we feel that our designs are finalized and should be available soon on our Resources pages.
Q: Will the SLB support external drivers?
A: Although we will support an external A-axis driver support to allow full 4-axis motion with the Vortex Rotary Axis, the SLB will not have support to external drivers for the X, Y, and Z axis.
Q: Will the SLB support accessories like the Vortex Rotary Axis, AutoZero touch plate, or LaserBeam?
Yes, the SLB will support all of our existing accessories for the LongMill, as well as opening up additional improvements and functionality to accessories, such as improved laser motion control, fully independent 4th axis control, and improved speed and sensitivity on touch probes and plates.
Q: Will the SLB support toolchangers?
A: The SLB does come with the hardware to support the IO for a toolchanger, such as relay control and tool length sensor inputs. However, we have not yet tested the functionality for a tool changer with the LongMill.
Q: Does the SLB come with a warranty?
A: The SLB comes with a standard 90-day warranty once it arrives at your door against all manufacturing defects. For further conditions, please check out the warranty tab on this page.
Details for returns can be found on our store policy page.

This was a terrific upgrade for something that was already pretty good – I just didn’t know how much easier and more functional and forward looking something could be until it was! Thank you very much !!

I have just used it a bit but had no problems converting.I must learn more about what it can do this winter which is when I have thee time
Gary Guilliams (verified owner) –
Better movements, only disapointment has been move alarms and work stops during the laser operations
Don B. (verified owner) –
My SLB is working great now. Through advice from Jason, I changed some settings in firmware to sort out some initial problems. I was initially interested in the SLB because of the computer module which didn’t happen because it wouldn’t allow for further expansion. The gcontrol panel I just received has connected to the SLB seamlessly. Together they provide an excellent interface/controller for my Longmill.

I love the SLB. It’s robust reliable, and offers some options for additional functions and tools. The support and documentation has really been quite remarkable. Sienci Labs a great company. I’ve had a good time getting the SLB up and running on my custom CNC machine. I actually would give it more of a 4.75/5 than a 4. The only thing I wish it had is the ability to connect external stepper drivers. The on board drivers work well, though.

LED strips does not work, talked with customer service, they told me they tested a board and sent it, when I received it still didn’t work. Takes a week of shipping each way!

Let me start with my rating of 4 because of the old dog adage. And the fact that I need more time with it. I have an old Genmitsu (I think) 3040 that was running Mach3. When the old PC died I needed a new controller. A friend steered me toward sienci.com and I’m glad he did. The SuperLongBoard and gsender are really good and the support including FB and YouTube have lots of answers. The group at sienci.com answered all of my questions even when I didn’t know what I was asking. I’ve had a couple mistakes but so far all issues are self inflicted and as time goes on I’m sure the rating will hit a solid 5. I would recommend the SLB and gsender as an upgrade or a new purchase.

Works as advertised. Have not had any glitches or problems. Run time seems to have increased on many of the projects run so far. love the expansion capabilities.

The hardest part of converting from the Buildbotics controller for my Onefinity was converting the connectors, but once that was done setting it up was relatively easy.
Been using it for some time now and it’s working trouble free.
I’m receiving a gControl Panel monday and I’m looking forward to connecting it up to the SLB which will give me touch screen control.
Doug Wilson (verified owner) –
SLB solved the problems I had been having with the original longboard.

Will not operate machine will only move x movement
Art Gibeaut (verified owner) –
Flawless guys, just flawless. Congrats on creating and producing a great product that was easy to connect and does just what you said it would right from the beginning.
Dave R. (verified owner) –
This is an amazing upgrade for the MK2. I like the option of mounting it to the rail of the machine. Saves space on my table. It was very easy to swap out. The instructions and videos were spot on.
Jon (verified owner) –
The problem was not necessarily with the SLB, it was dialing in the acceleration of X axis. Once that was solved, it has worked great. I do struggle with the fact I have had to make “sacrifices” to get everything to work. With adjustments made, I am not able to take full advantage of money spent on the upgrade.

In 2019 Sienci launched the LongMill Kickstarter campaign and I was one of the first to jump on the bus. It is fantastic to see their technology continuing to evolve and offer cost-effective upgrade paths for their machines over long periods of time. My recent purchase of the SuperLongBoard for my original MkI is a fantastic example of their commitment to obsolescence management, attention to customer feedback and a strategy to a continuous improvement life cycle that keeps them at the forefront of their industry and market.

I love that you guys are always improving your machines, and parts, all the time. Every time you upgrade your machines, you upgrade the Sienci family. It’s no wonder that you have such a successful business and a huge following of supporters.
Jeff McLoughlin (verified owner) –
Never having used its predecessor I can’t say if this is a huge improvement but it seems to work well. Why the enclosure look and feel is DIY I would guess is a function of the Sienci Labs orientation to the market as “makers” as opposed to woodworking professionals. Just guessing on that…

Chris and Andy Did a excellent job designing and implementing the Super long Board. It’s been working as it should.The manual shows all the information needed to connect and get up and running quickly. I use it 2 to 5 days a week to make a wide variety of parts and also some craft Items. I can’t wait to see what other products Sienci brings to the market.

My new controler is working like a charm, since I stop using the usb-c cable and start with an Ethernet cable. Merci beaucoup
