    I have not tried the vapor bath method with Dichloromethane yet, I applied it with a small brush. I will have to find the boiling point, if similar to acetone should work. Just checked the oracle. BP is 39.7 degrees so should vaporise the same. I will have a go and report back....

    I use Dichloromethane for smoothing and gluing PLA, easily available on t'internet. Also works with PET-G. Acetone for gluing ABS and acetone vapor bath for smoothing. Easy to make. Take a πŸ™„tuppaware box and put a 1/4 inch of acetone in it. Line 2 sides of the box with kitchen towel so it will act like a wick to help with even distribution of the vapor. Place the part on a wire rack or suspend in the box, we don't want the part to touch the liquid. Seal the box and sit it in a roasting tin. Pour boiling water into the tin. If the box is transparent you will see the acetone boiling off into a vapor. Acetone boils at around 55 degrees C so no need for direct heat. Keep an eye on it, it won't take long, 30 secs or so. The part will be sticky when it comes out so hang up until dry. WORK OUTSIDE, NO NAKED FLAME AND NO INHALING VAPORS! I would post a photo but The Dragon has repossessed her roasting tin and refuses to release it again. She said I could keep the tupperware box now that I have 'ruined' it....

    The basic principles are quite simple really, Everything is worked out on a co ordinate system, you could say fancy map reading or navigation. A map is divided into squares, each square being part of a numbered grid, same on a nautical chart. so to get from A to B, you navigate accross the chart, so point A may be square 21/06, 21 squares along and 6 up. Point B is say 18/32 so 18 along and 32 up. (asleep yet?) to get from A to B you will plot a route through the grid from one reference to another. Similarly, our CNC router, laser cutter 3Dprinter plotter etc works on the same principle, we have 3 axes, X Y and Z X being left to right, Y back and forth and Z up and down. Cad software converts a drawing, or draws as a set of co ordinates, so for a 2 dimensional square, the co ordinates could be, say, X0 Yo, bottom left corner, and X10 Y10 the top right. X5 Y5 would be the center of the square. To add a 3rd dimension, the Z axis gets involved, so on a 3D print, the first layer would be z 0.15, second Z 0,3 etc. I am using Designspark Mechanical to illustrate, the photos are, hopefully self explanatory... Next time will prepare the object for 3D printing.

    I had never mastered CAD until I found Designspark Mechanical, a free download from RS. It is so easy to learn and there are loads of tutorials on you tube. There is something immensely satisfying in drawing something up on the computer then watching it appear before your eyes. Learning Designspark and making the parts for my MMS went hand in hand, so instead of measuring off the plans and drawing on to ply or plastic sheet, I measured off the plans and re drew into CAD then printed the results. If you think anyone would be interested I could do a start to finish thread to demonstrate.....

    Go for it! If you get one in kit form it will keep the costs down, with the added advantage of learning how the machine works as you build it. Prusa probably do the best kits on the market, pricey but decent European quality. Tronxy or Creality are good Chinese machines starting at around 150 for something decent enough to get you going. Chinese quality has come on in leaps and bounds over the last few years and they have listened to the community and made improvements accordingly. And then comes the endless hours of fun 'upgrading'. There are plenty of on line forums and social media groups for advice and assistance, so for the price of a boat kit you can add a whole new dimension to your modelling skills. Not just modelling either, there is a thousand and one things you can do. For example, I replaced a Β£15 button on the washing machine in half an hour with 20 pence worth of plastic.

    There is still a range of skills involved, drawing up parts for printing, I use Designspark Mechanical , preparing the cad files for printing with a slicing program, setting up the printer and fettling the printed parts. I re made all the resin fittings and printed the superstructure parts for my MMS. I have also used wood for capping rails, doors etc and the results are well worth the effort. So, in answer to the question, I don't think it will remove the traditional modelling skill set, but it will add extra skills to out modelling arsenal. It will enable folk to make their own fittings at low cost, and at the end of the day if we end up with a creation we are proud of we can't really knock it. Photos show some MMS fittings and a Footy yacht hull being made...

    It is easier than you would think. I only got into 3D printing 2 years ago, once you see how it works the rest is easy. Main difference between a CNC router and a 3D printer is that a 3D printer adds material to make an object and a CNC router removes material.

    Bit of an update on my CNC router. All up and running now and I am well chuffed with the results. I abandoned the Arduino based controller and opted instead for a Duet 2 WiFi board, a 32 bit controller with on board drivers. The machine can be loaded with a job directly from my computer/laptop/mobile phone and progress monitored from same. I have also added a 7 inch Paneldue touch screen display for when my daughter is hogging all the internet bandwidth. It has been going for a couple of weeks now and I haven't stopped making stuff, all for other folks! I need to find some DXF files for model boats now. I have a set of plans for a Lysander aircraft that my mate wants me to cut out for him, so far my efforts to convert PDF into useable vectors have come to nought.

    I abandoned the job yesterday. Just come back to it now, I shut down all the open windows, restarted my PC, plugged everything in and away it went. I just tried 1 motor at a time and all is good. I can now wire the rest of the drivers up, make some new stepper motor leads up to the correct length, draw a nice box up with DSM and print it out, Happy days!

    'How did you get on? We are all agog here...!' Well, everything lit up as it should, but zilch as regards motion. I have an idea it is a software issue I am having. GRBL uploaded without a hitch. When I try and connect Universal G Code Sender, it says 'can't connect, COM 8 ( Where Arduino is connected ) is already in use, access is denied. I am assuming that the Arduino needs to be on the same com port as UGS... Getting splinters in me fingers from scratching me bonce now...

    Current is set via DIP switches from 0.2 to 5 amps, mine are set to 2.5Amps to match the current rating of the motors. Microstepping is also set via DIP switches, I have set mine to 1/8. Each driver has it's own 24V input so higher current is handled by the driver and not the CNC shield. I will try and video the results when I fire it all up (not literally I hope), I only have my phone camera, which isn't very good should be good for a laugh....

    I don't get 100 grubscrews at a time, I meant all sorts of screws. I have been fiddling about with wiring this afternoon, getting the drivers hooked up to the CNC shield. Just got to connect PSU to driver and CNC shield and it will be either Whoopee!! it works or a look at my on line banking for funds for more circuitry.... I am going to prove the wiring with just 1 motor/driver set up first....

    Cable managment all sorted. Electrics mounted on base, drag chains on X and Y axes part of the design, I will print them myself. I always get a shipping order for screws, usually a few hundred at a time, postage still the same. I have 20mm MDF and 20mm ply to hand for the spoil board and loads of milling clamps to go toward work holding kit, clamping arrangements will depend on what I am doing. I have also built a little platform for me to jump off in case I have to jump up and down on it in a rage when it won't work. I have several DTI's, Dial gauges, Depth gauges, and Height gauges lying around so have all I need to get her clocked in when the time comes. I am looking forward to seeing it burst into life. Many thanks for the tips...

    I guess I could make mounts for small spindle motors on the 3D printer. How is the cutting tool held in place? Do you use just a rigid coupler with grubscrews or a minature collet system?

    My plan is to trace PDF files into DSM and output as DXF, or work up my own drawings. I have DXF to G code so I guess I could deal with your files. When finished, my OX will be used for all sorts, cutting aluminium is a must, Daughter has demanded name plaques for her horses stable, she reckons her horsey pals will pay for nice carved name plaques so who am I to argue! ply and balsa cutting will be essential and possibly light brass sheet, hence my first choice of the 900 Watt DeWalt router. I may well end up with an arsenal of spindles/routers and eventually a laser head. I am using the CNC shield for now but the intention is to use a Rumba board, a versatile Arduino mega 2560 based board with loads of output options more commonly used on 3D printers, I have upgraded 2 of my printers with them already. Like 3D printers, the options for modifying/tweaking are endless. I will be fitting endstops, but I may use TMC 2130 drivers, which do not need endstops, as soon as they detect a substancial increase in current they switch off. My Mk3 Prusa has them, certainly reduces the ammount of wiring! I have a notion to draw up some plans for a series of warship boats at rc able size, ie, 47ft Whaler, Skimming Dish FML Cheverton Launch etc, interesting boats but rarely seen actually on the water as working models. I have a milling machine so a plentiful supply of milling cutters is available for a range of jobs.

    Hi. This machine is called the Ox, a full set of plates, anodised in black, is on sale at Oozenest at half price, I am building it bit by bit as I do not have funds for a kit. All parts are sourced in the UK, either from Oozenest, plates, extrusion some bolts and other Ox specific parts, Arduino Uno and CNC shield, the rest, Nema 23s, Toshiba motor drivers, bolts, some extrusions, 30 wheels, spacers etc from WE Do 3D Printing in Sheffield. Control will be via Arduino Uno and CNC shield, with Toshiba 5 amp drivers on a 24 volt PSU. This machine can be made as big as you want just by increasing the length of the extrusions, which consist of 20 x 80, 20 x 60, and 20 x 40 V slot. Mine will have a footprint of 750mm x 550mm, which will give me a build area of around 380mm x 650mm. Big enough for me, I have very little space and I am going to have to sell a couple of 3D printers to make room. I will be using GRBL firmware, Designspark Mechanical for design, DXF2Gcode for converting and Universal G code sender to cut. I don't anticipate needing a bigger machine as I cannot lift big models any more so 600 mm long will do me. I have not thought about work holding and my designs, If I manage to get ant sorted that work, will be there for anyone to use.I have not fully mastered the art of CAD yet, I learned Tech Drawing on a drawing board with T square and compass. This weekend will be a laugh as I am going to get the electrics sorted, I have mastered Marlin, used in 3D printing, and I have been laboring on the misapprehension that CNC would be the same, so it's teach meself GRBL time!
