GRBL Breakout/Shield kit now available

Today we released a PCB kit for a GRBL Breakout Board that fits the popular Arduino UNO Board.

GRBL is CNC Motion Control firmware that runs on the popular Arduino Uno board.
Connecting up wires can be a little fiddly when trying to connect up Stepper motors, limit switches etc.
So we decided to design a Breakout Board for it and make it available as a DIY solder up kit.

We have brought out the all the pins through buffer chips which are open collector outputs and also we have added a optocoupler IC for each limit switch. This allows higher voltage inductive sensors to be used, as well as micro switches.

Full information can be found on our website.

As well as connecting stepper motor driver control lines directly to the breakout board, you can also connect it to an existing CNC Machine Controller board that uses a DB25 port and hence you then have USB control !

Here is a video showing it in action.

Update July 2017

Sorry for the lack of updates and newsletters, we have been busy as usual and having fun!
First update is that we are having a sale on the Guitar Pickup Manual Coil Winder.
Full details can be found on the product page:
Second update is on the CNC 200mm Coil Winders.
After a long wait, We are now full time on getting the next batch of 200mm Coil Winders complete and should have them back on the shop by the middle of August.

Sorry for the delay on these, but we have not stopped making them, we have just had a lot of different projects to juggle this year.
But we are getting there !

The new batch of 200mm Coil Winders have had a couple of changes.

First being that the motor power supply input is now away from the controller box and mounted at the back of the machine with an on/off switch.
And secondly, Closed Loop motors will now be supplied on both the Bobbin motor and Feeder (traverse) motor. We have been supplying the Bobbin motor with a closed loop motor for a while now, but always left the Feeder motor open loop, as it does not require to travel as such high speeds and also kept the price down. But we have now done a deal where it only costs slightly less to use Closed Loop motors on both and improves the performance and accuracy.

March 2017 update

A bit of a long time since our last update!

2017 has been a bit crazy for us as we have been working flat out on getting a new SECRET! product finished for launch.
It has been in the making for the last year and we have spent the last few months finishing off the prototyping and heads buried in coding of the firmware and example software source code to be released.
The new product will have it’s own dedicated support site which will go live very soon.

More information on this product when it is due to be released.


Some more updates on the following:

CNC 800mm X 800mm machine.

Due to other projects getting in the way, the launch of the CNC 800mm x 800mm machine kit is still delayed.
We have had a huge interest in this machine and can only apologise for not getting it to market yet.
Being a small company with limited budget and limited resource, we have to juggle the projects and products to match what we can cope with at the time.
We spent a lot of money and time getting from prototype to finished product and right and are more than keen to recuperate some costs and get it to you guys, so please bear with us.


200mm Coil Winders.

Unusual I know for us to let this popular model run out of stock for so long, but again because we make all our machines here in our small workshop and there is only two of us full time, we have just not had time to make up the next batch.
We do have a email list with people waiting and we will be cracking on with making up the next batch as soon as we finish launching the new SECRET product !


Manual Guitar Pickup Coil Winder.

We designed a Manual Guitar Pickup Coil Winder at the end of last year and instead of selling it ourselves, we have branded it under the Crimson Guitars label and they have sole distribution on it. We have been meaning to update our web pages with the full information, but it is actually now on sale and can be found on their website. We will update our site as soon as we can.


So just a short update to let you know we are still around and more update soon.

Crimson Guitars release a new video review of a Manual Coil Winder

Crimson Guitars release a new video review of a Manual Coil Winder we designed and branded for them .

In answer to a few of their points raised in the video

The auto traverse add-on plugs in to the back of the machine and will bolt onto the tapped holes of the base plate. 
We will release information so people can build their own auto traverse add-on or if enough demand we can make a few up.

The Gauss and Resistance again plugs in the back and is a separate unit. So again we will be showing people how to build their own add-on or releasing one. The gauss meter allows you to test the strength of the magnets and also the polarity.

The Bobbin plate has a number of spaced, tapped holes for popular pickup dimensions. Most people would use M4 bolts and attach the bobbin with no slugs in to wind, then insert slugs after. This would mean the bobbin is held securely in place while winding.

The magnets were supplied to be used for pickups that already have the slugs in and needed re-winding.

Maybe a tail stock add-on also in the future could also be in place for people attaching the pickups to the bobbin plate the Crimson way !!

All the plates are aluminium and bead blasted, followed by oxidization treatment.

We have seen posts in other guitar forums where people are indeed winding at 3500 RPM, so we decided that we would over engineer 🙂

The machine was planned to go out as a kit for people to assemble, this would keep the price down. But we have built the first 25 units and branded for Crimson Guitar members as a free build service.


Thanks again Ben and Luigi.
