FabLab Pembrokeshire have the first-ever SheetCNC Mk3, installed and operating in their main workshop in place of their old Mk2. Assembly went without a hitch, the machine being built and commissioned by one person in the space of just two working days. Already a FabLab member is creating a SiameseKAT from MDF, while a group of FabLab members are designing and building radio-controlled hovercraft from Depron foam. So, Mk3 kits will be available very soon.
It’s been a long time coming, but now the first Mk3 under-frame and table are being cut. With luck a complete Mk3 prototype will be in operation within a few days. Watch this space 🙂
The new high-speed Z-axis on the Mk3 gantry enables full 3D machining. This 26″ model car is made in two parts from 100mm polystyrene.
The first prototype of the Mk3 gantry and spindle carrier assembly was mounted onto an existing Mk2 SheetCNC bed in our workshop last week. The new gantry gives us the facility to do full 3D machining, as well as greatly improved 2.5D capability. First test results are even better than we expected. Stiffness of all three axes has at least doubled but with zero weight penalty. The Z-axis speed has quadrupled but without sacrificing vertical precision. To say we’re pleased with the outcome of all this hard work would be understatement.
FabLab Pembrokeshire’s CNC course continues on Wednesday evenings. Their SheetCNC machine is now completed so the course will now focus on how to use CAD and CAM, and how to operate SheetCNC. Membership of FabLab is free, and the course is free too! If you’d like to join the course, do get in touch with us and we’ll put you in contact with FabLab Pembrokeshire.
FabLab Pembrokeshire’s SheetCNC Mk2+ is coming along well. The course runs for only a couple of hours each week so progress has been… well, let’s call it ‘steady’. The machine is now mechanically complete. Just the controller to add and then they’ll be cutting their projects in no time.
A big thank you to everyone who said such nice things about KRAB and SiameseKAT during Maker Faire UK. We had a fantastic time and it was lovely to see so many smiles. We hope to be back again next year, with some different robot designs.
Our two walking robots, KRAB and SiameseKAT, are boxed-up ready for the nine-hour drive up to Newcastle tomorrow, where they’ll be roaming around the Maker Faire UK 2017 exhibition. If you’re in the Newcastle area do get yourself along to Maker Faire – it is one of the best maker shows anywhere in the UK. Doors open at 10am on 1st and 2nd of April.
New: We’re now offering a try-SheetCNC-from-home facility. Simply send us a DXF drawing of a part you’d like to see SheetCNC cut, and we’ll send you a video of the part being made. To learn more, please click on the link in the main menu.
We’ve further improved the design of the SheetCNC Mk2 gantry. The new lattice structure reduces the moving mass yet increases the rigidity. No change in price from the original kit.
A major redesign of SheetCNC is being sketched-out, to be developed over the coming weeks. This will incorporate a pre-made floor-standing frame. So no more having to build-up the frame from cut timbers. The new floor-standing structure will hold the bed perfectly flat with no need to level the bed manually. We’ll also be redesigning the gantry and spindle-carrier to increase stiffness for even better precision. We’ll also be looking at speeding up the Z-axis 2-fold or even 4-fold to enable full 3D work.
FabLab Pembrokeshire has purchased a SheetCNC Mk2+ kit. They’re running a comprehensive course on building and using large-format 2.5D CNC. We’ll have some pictures and videos of the finished machine when the course is completed after Easter.
Great news: we’ve been invited to exhibit our robots at Maker Faire UK 2017.
We’ve applied to exhibit some walking robots at Maker Faire UK 2017. The robots are eight-legged beasties loosely based on Theo Jansen’s StrandBeest leg mechanisms. None of our walking mechanisms actually works properly yet, so we’ll be taking time out from SheetCNC development to get them up to scratch. Don’t worry – our support for SheetCNC users will carry on uninterrupted!
SheetCNC has been upgraded. The Mk2, now available, offers 120mm Z clearance, longer Z-axis, and faster axes all round. The extra clearance allows room for machining 100mm products with room to spare for the spoilboard and for safety clearance. The quicker axes have halved typical machining times. Price remains unchanged.
