Community forum launched!

I’m excited to announce brand new community forum to seed brainstorming and ideas around motor control related projects. The community forum is the first-hand media to get the latest updates of motor control development.

First 50 community members will be given an exclusive access to a private SimuCUBE’s beta testing forum. They will be the first ones to get to test-drive the beta when it’s released.

Join now at: https://community.granitedevices.com

communityThis forum will be also the official discussion forum for this Blog. The link is on the top navigation bar. See you there :)

 

 

Argon servo drive firmware 2.1 adds SinCos encoder support

The just released Argon servo drive firmware version 2.1.0 adds support for encoders with analog Sin/Cos outputs. Drive allows selecting interpolation factors of 16, 64 and 256 for such encoder. This means that an sin/cos encoder with 1000 lines per revolution, would give resolution equivalent of 256*1000 lines. In addition to this, normal quadrature decoder 4x gain applies on top of that, meaning that 1000 line encoder will yield total resolution of 1024000 counts per revolution.

The FW upgrade contains also many other improvements based on the user feedback that we have received. For full list & download, see firmware page at wiki.

New ATOMI servo & stepper drive boards are here!

Earlier announced ATOMI is finally getting the focus it deserves! Now we have second revision boards under our scope for testing and firmware development. From initial tests, we can tell that we’re very close to the final design. At the moment it looks like we need only to change one resistor value on the PCB to make it final.

We can thank Esa Hippolin from the beautiful hardware design.

SimuCUBE final hardware has just born

Today we received the first samples of final SimuCUBE board designs. Testing of it shows no flaws so we’re giving the green light for the first 250 pcs batch assembly! All parts are already in stock, so assembly should not take too many days.

The photo above shows also the work-in-progress test bed for SimuCUBE that will be used to test & verify the operation of every shipped SimuCUBE. The device under test will be placed on the top of the bed and the spring loaded pins will contact certain pads on the bottom of the SimuCUBE board to allow tester to contact all necessary signals at once.

The first SimuCUBE is real!

Prototypes of SimuCUBE motherboards and acrylic case have just arrived! The first successful test drive has been done with a big smile :) We hope to have Indiegogo campaign launched on the next week. Get ready for early bird specials!

SimuCUBE – the force feedback controller from the future announced

I’m happy to reveal the details of the upcoming force feedback controller – SimuCUBE! The hardware design is now complete for prototyping and we will get prototypes in the lab in the next month. SimuCUBE has a STM32F4 microcontroller that is compatible to a popular STM32F4 Discovery board. The plan is to start an open source firmware project for this board.

New web site

To celebrate the launch of the completely redesigned main granitedevices.com web site, we have started an ARGON & IONI sale campaign that lasts for one week. Grab the discount coupon code from the main site front page before it’s gone!

The new site

The new site

The web site is the first complete renewal since the original site introduced 2007. All content has been written my self to guarantee maximum accuracy in details. I hope it’s more clear and informative than the old one :)

ATOMI – the ultimate 4 axis CNC controller

We’re proud to announce ATOMI, the revolutionary multi axis drive for CNC applications. It is a closed loop stepper drive that essentially turns stepping motors into servo motors. ATOMI gives the benefits of both worlds: reliability of servos and high torque of steppers.

ATOMI age is coming

ATOMI age is coming

ATOMI will be launched in the Indiegogo on Q2/2016. Stay tuned and grab the early bird specials!

Ps. it is largely based on IONI technology. IONI Pro will get all the same features than ATOMI through firmware upgrades.
