SOLD! Duet3-controlled RatRig KillerBee 1075 CNC

It's time for me to move on from my RatRig 1075 KillerBee CNC machine, which has served me well with my hobby over the last 12 months - and yes, it's only a year old! It is fully configured and ready to run - you only need to provide a PC.
I’m selling my RatRig KillerBee 1075 CNC milling machine, which is fully configured and ready to run. This would suit anyone with an interest in CNC woodworking hard or soft woods, and those who wish to produce machined woodworking for a new or existing business. The machine is a solid, properly fettled woodworking machine, also capable of machining non-ferrous metals, acrylic and other materials.
The CNC machine is controlled by a fully configured 32-bit, Duet3 control board via a 24v power supply, both of which sit inside a fan-ventilated enclosure. The enclosure can be mounted on the wall or beneath the worktop.
The CNC machine is constructed from 2040 C-beam aluminium extrusions and 8mm thick steel plates for exceptional rigidity, and the MGN15 leadscrews on all four axes, which are all fitted with needle roller thrust bearings, are driven by high torque NEMA23 1.8degree/step, 345oz/in stepper motors. Proximity sensors are installed on all axes, providing auto-alignment of the Y axes, and flexible drag chains provide cable support and management. The work envelope of the machine is 550 x 788 x 100mm.
The CNC machine was bought from new in March 2022 and comes configured and ready to run, but you will need to provide the laptop or PC to access the interface of the Duet3 control board via a web browser, via a network cable.
The milling motor is a Sorotec SFM 1000 PV-ER, which has soft start, infinitely variable speeds between 4,000 and 25,000rpm, idle speed reduction, constant speed under load and integrated overload protection. It has a ER16 collet with high-precision concentricity of <0.05mm at 25mm (in the cone < 0.01 mm) due to the balanced armature and. An enclosed double ball bearing is used for better absorption of axial forces. It comes complete with a 1/8" and a 1/4" collet and a 43mm mount and dust shoe.
Also included will be the spoilboard, which is practically unmarked. It is manufactured from 25mm thick, moisture resistant (green) MDF with 4, 19mm t-tracks and an array of threaded inserts to hold the workpiece. The spoilboard is removable to allow for milling the ends of boards for cutting dovetails, although a cut-out will be required through the table/surface it will be mounted on.
If you have any questions, please feel free to make contact, but it’s highly recommended you come to see the machine in action, to explain its operation in more detail and demonstrate it working.
It’s located in north Wiltshire, on the border with Gloucestershire, in the United Kingdom.
Payment by bank transfer only, please, and you can take it away once payment has cleared. Not before, sorry. It's too big/heavy to ship, so it's collection only.
Priced at £1250 including the Sorotec milling motor and mount or £975 without.
The Killerbee can be used with a Makita RT0700CX4 Compact Router or similar, and I can provide the 65mm mount, if required.
