Sienci Labs Inc. will ensure that the appropriate support is provided to the original customer to restore the AltMill to operational condition or provide a full or partial refund under the sole discretion of the Company.

    This warranty does not cover damage due to improper use or assembly, lack of maintenance, normal wear and tear, or modifications to the AltMill which are not produced or authorized by the Company. Consumables such as cutting tools and sample or stock materials which may have come with your AltMill are not included in this warranty.

    FAQ

    Payment

    Full Payment is required at time of purchase to get your order into the Queue. We ship on a first-come, first-served basis. If you choose local pick-up, you are subjected to the queue order and cannot get your machine quicker.

    Power Requirements

    We recommend allocating two 15A 110V/120V circuits — one for the spindle and dust collection system, the other for the machine and a computer.

    • The AltMill consumes 500W and runs off a 48V 10A power supply
    • The 1.5KW Spindle Kit consumes 1500-1600W at max load

    If you live in a country with 220V/240V power you must use a transformer to convert to 110V/120V.

    • To solely run the machine, you need a rating above 500W
    • To run the machine and spindle, you need a rating of 2000W

    International Shipping

    We do not have distribution centers but we ship internationally from our office via UPS.  Shipping costs vary from $300  to $1900 USD. You are responsible for any taxes, duties and brokerage fees.

    3rd Party Spindles

    I would like to source my own spindle, what should I be aware of?

    • For spindles 2.2KW or above, you will need to install extra 220VAC wiring
    • The AltMill comes with an 80mm spindle mount, we do not have larger diameter mounts at the moment
    • The VFDs that may work with our controller are: Huanyang v1, Huanyang P2A, Yalang YL620, H-100, and GS20, however they are not plug-and-play — read this article for further information

    2. John Webster (verified owner) –

      I upgraded from a 30 x 30 longmill that I bought second hand. The new Altmill has exceeded all of my expectations for speed and quality.

      I appreciate the careful tolerances and precision machining that went into the individual parts- assembly was straightforward and the completed unit was square and true in all axis’

      When I placed my order I was concerned that tariffs would get in the way but this turned out to be a non issue. The machine is such a great value that I would have still bought it even with a tariff.

      Your company really is exceptional in terms of customer service, continuous improvement and product engineering.

      Thanks for helping me take CNC off of my wish list and putting it in my shop!

    4. Ron Martinellil (verified owner) –

      Absolutely love the CNC. Every portion of the design is much more professional than my prior CNC. The assembly instructions were excellent and I greatly appreciated the support provided by Sienci Labs prior to my purchase. I reworked my machine to a 3′ x 4′ machine and it’s excellent.

    5. Kevin Kohlhapp (verified owner) –

      Great machine which has been well designed and built. The one issue I had was with one of my Z motors. The box had been opened before I received it and the motor did not work. After trouble shooting the issue Scienci Labs were great about sending me a replacement motor.

    7. Bruce Campbell (verified owner) –

      Need more info on spoilboard – 1 or 2 layers pro/con
      Tramming – eccentric nuts not mentioned. I had no idea what they were until I watched the IDC Woodcraft Youtube videos.
      More detail on sensor setup. Preliminary placement during assembly and verification of the gap just prior to motion testing.
      Change ‘power on’ sequence to a single switch. The Estop use seems to be excessive

      I have owned this CNC for a little over a month now and I have to say the experience has been fantastic! I don’t think there is another CNC in this price range that can come close to matching it. Very easy to assemble and everything worked perfectly.
