Award winning budget printers from CraftUnique! Craftbot 2 and Craftbot 2XL

EmvioENG now working with CraftUnique

Following on the theme of top printers, we are excited to be working with Craftunique from Hungary! EmvioENG is an official UK partner, importing, distributing, selling and servicing the Craftbot range of machine!
The Craftbot printer range has, this year, won 2 awards issued by


We met the CraftUnique team at TCT in 2016 and have since started importing the Craftbots to the  UK. Of particular interest to us has been the Craftbot 2 and Craftbot XL as they are now fully updated with the latest nice-to-haves anyone would like.

Both machines have a very solid build. Steel chassis, Linear rails on the XL and all metal construction throughout. Oh and whats more, you can also specify the colour of the machine you would like! We have the blue one but the anthracite colours are really good too.

    Extruder mechanism upgraded: Bondtech Dual Drive

    Since early July, we have a had a very successful working relationship with Bondtech, the Swedish company producing Dual Drive extruders. The Bondtech extruders without question have brought a step change in reliability of extrusion. Main characteristic of course is the driving mechanism used: Twin counter rotating hobbed wheels.

    Teaser alert! What we have been secretly organising

    You know the counter in the machine tools page. Well it is counting down to the 19th of August 2016, the day we unveil our grandest product to date. the unveiling will be done in the Thornbury model engineering exhibition so why not check us out at stand 134.

    You can find more about the BSMEE on the official exhibition webpage

    We are distributors of Bondtech products to the UK and IRE

    The big news of the week is that we are now the UK and Ireland exclusive distributors to all the Bondtech products. Bondtech extruders have understandably revolutionised the reliability and speed of printing using filaments. The team have a series of mounts to allow adapting the parts to any prosumer quality printer that are freely available from us or from Bondtech directly. (more…)

    BCN3D Sigma: Cleaning the filament feeder

    About 7kg of filament later and lots delightful prints with the BCN3D Sigma we noticed  that ground filament and dust had accumulated on the extruder feeder gear. Perfect opportunity to clean the filament feeder by taking it apart, checking out how it is engineered and learn a bit more about the Sigma!

    Here is how we did it step by step.

    Step 1. Unscrew the socket cap screw shown below to release the bottom Bowden tube. the printed part holds against a nut which is screwed on the tube. Simple and effective!

    Step 2. Unscrew the 2 nuts holding the stepper motor board shield and unplug the stepper motor. Try not to lose the tubular spacers! Take them out and store them safely.

    Step 3. Remove the top Bowden tube from the feeder by pushing down on the grey ring and pulling the tube out . Then unscrew the nuts holding the stepper motor bracket on the frame. Remove the feeder from the Sigma.

    Step 4. Now start taking the feeder apart. Unscrew the large grub screw and remove the tension adjustment spring. Then unscrew the 3 long hex screws which hold all the parts on the stepper motor.

    Step 8.  Dissemble the feeder and clean all the parts from filament grindings and dust with a small brush. A toothbrush will also do!

    Step 9. Reassembly time! Start  by placing the aluminium bracket with the bent part facing towards the cables. Then the plastic spacer and pinch levers as shown below.

    Step 10. Insert the tension spring through the hole of the top lever and screw in the large grub screw to compress it. In my experience 1 turn after the top of the screw is flush with the lever surface give a good starting point in terms of spring tension.

    Step 11. Take the feeder back to the Sigma and fix the bottom Bowden tube on before mounting on the frame, makes life easier! Then slide the feeder on the studs of the frame and fix it in place with the 2 nuts. Connect the motor back to the driver. IMPORTANT! Don't forge the spacers!!! 2 on each side of the board.

    Step 13. Fix the aluminium stepper driver shield back on and insert the top Bowden tube. Done! grabs beer...

    CAD mock up of R8 Spindle and QTC tooling

    Drawbar tension for R8 and MT3 collets to work safely with QTC tooling?

    We have been asked on a number of occasions, and seen in a number of forums, the question of "How much tension should I put on my drawbar when I use  Emvio (or Tormach) repeatable Z tooling?" This question is a very common for those looking to make a pneumatically actuated drawbar using Belville washers. So what do you need to know about Drawbar Tension? (more…)
    BCN3D Sigma 3D Printer

    We take it apart so you don’t have to: BCN3D Sigma

    The only way to be sure that any machine is really well designed is to take to bits and have a look inside it! That’s what we did at Emvio Engineering with our BCN3D Technologies Sigma! Oh why not check it out in our shop too
    Under the beautiful bottom cover of the Sigma we found the electronics and were impressed with the cable management and over all neat setting.


    Then it was time to pull the Z axis out for a closer look… The 2 vertical rods are held in place with welded studs on the frame which made the task very easy. The print bed support made of bent aluminium is very stiff and those side cuts look awesome. The black heat bed sits on a cork pad and both are suspended by 3 springs in triangular arrangement.

    I did wonder what was behind the slick looking print heads. Started by removing any screw stood in my way! The nozzle was out and in less than 10 seconds in under a minute the linear slide was revealed. It runs unworldly smooth with no play at all!

    Here is the official maintenance video from BNC3D Techonologies showing how easy it is to remove and replace the hotend

    To Be Continued..
    in the next episode we will take apart the X, Y motion system and extruders!

    Emvio Engineering is now a reseller of all BCN3D products

    It is with great pride that we bring to the UK market the products designed  BCN3D Technologies.

    BCN3D Technologies started off as a project of Fundació CIM, which has more than 20 years of experience in Rapid Prototyping and knowledge transfer. The results have been impressive and that is why when we first came across the company, we were keen to collaborate with them

    We will be keeping stock of as many of their products as our limited storage space allows but will be giving priority to the Sigma. As you may have seen in our earlier post, we were giddy with anticipation when the Sigma was released. In no time you will be able to browse our shop for all four of BCN3D printers:

    BCN3D Sigma 3D printer

    The BCN3D Sigma – The flag ship model that received the best quality award on 3Dhubs page for April

    The BCN3D Lux – A SLA machine working with photoreactive resin allowing for fantastically fine layers and printing speed

    The BCN3D Plus – A Prusa clone kit aimed at those wanting to build their own printers

    The BCN3DR – Another kit but this time for a Delta printer

    The BCN3D Ignis – a premium 100W CO2 laser cutter with honeycomb bed and a 900×650 working area

    Emvio Engineering Nema 17 stepper motor damper installed

    Damping the sound of stepper motors on 3D printers

    Most of us that tinker with 3D printing have wondered how to reduce the groan and squeal of the stepper motors driving us nuts. Especially when long prints are involved! For a while now we have been using and selling our own vibration dampers that place a rubber buffer between the stepper and the printers frame. The rubber is thin and stiff enough to maintain accuracy of the stepper motor while reducing the vibrations being transmitted to the body of the printer. (more…)
    BCN3D Sigma 3D Printer

    Exciting times, European 3D printer that kicks ass!

    After looking around for a the hottest 3D printer to try, we have finally settled on a brand that will give the top players a run for their money.  So we would like to tease you all with the new kid on the block: BCN3D's Sigma   Pretty sleek. Serious engineering going on and a CE mark to boot. Where can you start?
    • Enclosed design with 210x297x210mm build volume
    • Dual heads independent that park when not in use
    • Profile linear rail, not round bar, on the axes!!!!!!!!!
