Coil Winder ARM Controller Software 3.1 released with Firmware 1.5

We have always stated that our software and firmware is always in development and the main reason is because the more Coil Winding Machines we sell, the more weirder and more wonderful applications people seem to use it for.
So as we get bug reports or feature requests to be added, we try to release a new version as soon as we can.

Recently we sold a machine to a customer who needed very accurate movements down to degree level, using the Scripting engine and off the back of this a few small bugs were found.
These bugs did not really effect the normal Automatic winding feature of the software and firmware, but when sending thousands of quick short commands, there was some tweaking that needed to doing.

The tweaking has ended up in a lot of time re-writing chunks of the firmware and software code and a lot of time sat in front of the machine with a scope and a lot of various combinations of commands being fired at the controller.
We also attached various Micrometer Dial Gauges around the machine and external pulse counters to check every mechanical movement was coming out the same as the scope the debug feedback information from the processor.

I have got to add a great thanks to Dan for really putting the machine through testing and the time he spent helping us out.

Also while tweaking the code to obtain small accurate movements, we have ended up with much cleaner and faster pulse trains, that now improves accuracy and repeatability over the full range of speeds and pitches.
The firmware now looks more closely at the frequency of each motor and taking into account the interpolation that is needed between both motors, alters the pulse train to suit that speed and adjust automatically where needed.

These changes now offer improved return to zero positioning and also resume from pause improvements and higher speeds.
All new machines and ARM controller upgrades will be going out with the new Software and Firmware as default and it is highly recommended that if you have a machine with the new ARM Controller that you upgrade.

As usual the new Software and Firmware can be downloaded from our downloads page.

It has always been free to our customers and will remain so in the future.

Before you upgrade your firmware, please make sure you read the instructions in the forums.

CNC 800mm x 800mm Page Updated

The product pages for the CNC 800mm x 800mm Routing Machine have been updated with some new pictures and specifications.

We still want to do some videos showing the machine cutting out various materials, before taking orders for the first batch.

We have also now finished documenting the assembly and wiring instruction manuals for the new CNC 800mm x 800mm Routing Machine.

These can be viewed in the Support Forums and if you are interested to view them before purchasing, then do not hesitate to contact us on and we will get a account set for you.

It has taken much longer than we anticipated getting the machine kit ready for market and this was mainly down to the workload we have had with building our batch machines and custom machines for customers. But we are getting there !

Downloads Page added

We have now duplicated the latest software and documentation out of the Customer Support forum to a public Downloads area.

The link to the Downloads area can be found on the top navigation menu of the site.

This should make it easier for existing customers to download the updates and also for potential customers to download the software and take a closer look.

More detailed posts will remain in the Customer Support Forum for now until we decide on a migration solution.
