Thread: 3.5 NG Conway or Lilla
23/07/2019 23:26:30

Can i add a 3rd choice ?

Hunslette by Don Young. 3.5" Hunslet available from Reeves

Lilla comes up quite big in 3.5" because it's a port class Hunslet (i think). Lilla was printed in Engineering in Miniature Vol 1 & 2. and is available from Blackgates. The articles are good as they offer both castings and fabricated versions.

I started to buy the parts for Hunslette but who knows when i will start it.

Good Luck with your choice

Thread: Editing .STL Files
09/01/2019 21:41:30

Yes i've had a dabble with stl files........Yuck

First thing is an stl file is a mesh and the object is made up of triangles. Loads of em. If it's something engineering rather than artistic you can open it in designspark. Select the object and do convert to solid. You can then sometimes mess about with the file. Then resave as and stl or designspark file for future editing. If its something artistic then head for meshmixer. You can muck with all the triangles pushing and pulling the shape. It's best if you can download the file in it's native cad format rather than stl.

Thread: PLA not Sticking to Bed
04/01/2019 19:04:14

Hi

I've had a shower and it gives you time to think.

Maybe stick is not your problem.

I cant gauge the size but it looks like a big "slab" of plastic. What you seeing is the same as the problems you get with ABS. This is caused by Hot Bed-Hot new filament-cooler filament in the middle sandwitch, The print is sticking to the bed but is being pulled off by the cooler layers above.

Maybe you could also try reducing the infill %.

There's a good troubleshooting guide here **LINK**

Hi

I you have a PEI bed you shouldn't put anything on it to aid the stick. My robox has PEI and everything sticks to that.

I would try raising the bed temperature and see if it makes a difference after all that's why it normally is used for PLA. The Robox likes 70 for the 1st layer and 65 for the rest. The Ender 3 i use 65. Your printer / filament combo may need you to alter it a bit

Thread: Cheap 3D printers
11/11/2018 15:41:58

Thanks Michael

I'm glad you found the long post helpfull

Just seen it today **LINK**

Ender 3X with extra glass bed & free nozzles £139 delivered from Germany (no import duty). Mine came fom Germany and only took 6 days.

Its a good price for an all metal framed printer ,no acrylic panels

or you could make your own. Ender 3 open source design files here **LINK** but it might cost more.

Hi

I have 2 X 3D printers from different ends of the price scale. A CEL Robox at the high end and a Creality Ender 3 from the low end. Both print PLA and ABS.

The Robox is very much a draw something, pick your filament type and print machine. No fiddling or tinkering it just does what it is supposed to very well. Its a closed system with CELs' own software and hardware. The filament spools are chipped so when you insert them the printer adjusts itself to produce the ideal print. I can use non CEL filament but i have to configure the print manually. ABS likes to be printed and kept warm for the duration of the print to prevent warping and splitting. The Robox has an enclosed build chamber for this, It can also print PETG & Nylon

The Creality Ender 3 was £150 delivered from the UK and for that money it is well worth it and you cant go wrong. It comes as a semi kit. It is open source so you can replace parts easily if needed and run a variety of open source software. All free. It prints PLA, PETG and ABS. It has a non enclosed heated platform. If printing ABS you are relying on heat from the bed to rise up through the print to keep it warm. This works and i am printing ABS now but the problem is how high you print off the bed. So that's your limit with ABS. For me 60mm high is fine but i dont know how high you can go. PLA & PETG dont have this problem.

I you do want to print ABS choose your filament carefully. Some ABS likes a really hot bed over 100 degrees and this printer (mine cant) might not be able to reach and maintain this temperature in an un-enclosed environment.

ABS from 3DJake called NiceABS prints at 250 with a bed of 85 for me and prints just fine.

Look for Ender3 reviews etc on youtube.

So Ender 3 £150 + 2 X 250gm 3D Jake PLA + 2 X 250gm 3DJake Nice ABS £41.50 (over £40 delivered free) = £8.50 for beer.

This will be the start of a huge learning experience

Thread: orientation
27/09/2018 19:16:26

Hi

Are you sure you are drawing with the axis set correctly in Fusion. In the preferences there is a setting called "default modelling orientation. The default for this (no idea why) is Y up. Everything you draw has to turned to print. Took me ages to find it. Change it to Z up. Things look a whole lot better

Thread: Cura 3.4.1
17/09/2018 09:17:40

I did upgrade recently but changed back to 3.3.1. There is a problem where prints dont start. A message appears on the LCD to "Click to Continue" so you need to press the LCD button. This happens perhaps twice before the print will start. I'm not sure if it also pops up during prints.

Thread: PLA Filament Breakage
23/08/2018 08:59:14

If it breaks like spaghetti then i think this means the filament has been exposed to damp. I never had a roll do it but i have had those 5M samples from China do it. Best place for it is the bin unless you want to try drying it in the oven. Dont get it too hot or you'll end up with a big lump of plastic. Humidity and filament dont mix. All my rolls are in zip lock bags with silica gell. Never leave a roll on a machine when not in use. Any moisture will show up on your prints as the damp turns to steam in the hot end. Humidity today 68 %

Thread: Cad / cam and slicers , im
16/02/2018 09:18:07

I use Fusion 360 for my drawings. I find it easier than TurboCad. I have a CEL Robox that has proprietry slicing software. Given a choice pick Simplify 3D for slicing etc as it has the best features

I saw that on the BBC news webpage by accident. We applied and within 2 weeks we had a letter saying I had paid too much tax. I then got a refund check for £431. Nice

Just found it again on the beeb http://www.bbc.co.uk/news/business-41365084

Hi

Have you thought of trying a MT2 reamer just to try and clear the burr. RDG sell them **LINK**. Just an idea. I'm no expert

Thread: LED Light Bulbs
08/01/2017 16:01:57

Hi

I had this in the hallway landing light upstairs when you have two way switching. I believe the problem is caused by capacitance of the long cable running to the downstairs switch. The cable is so long that the capacitance of the between the live and switch line is enough to cause the light bulb to strike and then decay and hence the flashing. Sometimes the bulb would seem to glow.

Thread: Gear help needed please
15/12/2016 19:31:08

Hi

I do have 2 x 3d printers at home. I have tried printing gears before but not had a great success in the smaller sizes. As already said in the thread the tooth definition does seem to disappear. If you put the STL file somewhere i would have a go but couldn't promise the result you may want.

I think you may be better going to the the 3Dhubs site. **LINK** It is a network of people with 3d printers who run jobs for people like yourself. You will be able to find a hub local to your location and maybe consult with them and obviously collect the result in person.

Hi

Would it happen to be a Hotpoint Fridge Freezer with the fridge on top above the freezer by any chance?
