Updated Photos in ‘About’ and a New 3D printer enters the space!

If you haven’t seen the space recently, and are curious about how many abandoned laptops are scattered around (Surprisingly, not as many as last year) take a look at https://lamm.space/about/ for updated images of the space, and the new PCs, 3D printers and equipment.

We have also been given a very kind donation of a dual extruder 3D printer. It is a bit dusty, but think of the possibilities!

Another 3D Printer

Prusa Control

In the third post of the month/night after a cabinet and a Google hat I wanted to quickly talk about Prusa Control. Prusa Control, for the uninitiated, is a cut down version of the, very useful and powerful, Slic3r software for the Prusa printers.

Prusa love Slic3r and there is no reason to doubt it. They build a custom profile for the software and make sure it is shipped and linked across their brand. however they note that it can be over-whelming for beginners. That’s where Prusa Control comes in.

Prusa Control is aimed at ease and speed and with just settings for the Prusa 3D printers and there is something lovely about that. I have installed the beta and used it for a first print in my new cabinet.

It worked really well.

In fact I would say close to perfect. I printed with a brim and with loose settings (.2 at 15% infil for speed and ease) and I got a near perfect print with good bridging and detail and a wonderful layer height that is regular with no breaks or interrupts. The brim was light and they clearly had taken care to make sure it was a well printed but easy to remove printing support.

So for new users and for experienced users wanting to cut out the interface and get straight to the printing then it is worthwhile having Prusa Control next to Slic3r in your toolkit.

I also liked how smooth the layer height display worked after generating which is very quick and efficient.

A very clean and easy to understand interface greets you on opening, seriously the controls on the side are all you have to deal with, this is minimal and almost perfect

One of the prettiest and nicely printed brims I have ever worked with

3D Printing Cabinet

I haven’t managed to get to the Space much in the last couple of months (again! – though at least I did my duties as a director, such as making some posters (see another blog to come soon) and attending meetings doing admin etc.) mostly due to summer holidays and the pressures of family life. However home projects haven’t stopped and I have a couple of blogs to talk about what I have been up to on the home front.

The first of these is all about my 3D printing cabinet. I was gifted a 3D printer (Prusa i3 Mk2 that I constructed with the affable TBSliver) detailed in a video to come soon. It has been working well but I often have prints that lift on one side.

After some discussion, with the amiable (and affable and affordable) TBSliver we decided it could be the drafts in the room. So again from a suggestion by the amazing TBSliver I decided to build a cabinet to hold my printer. To do this I used:

  • Two tables from IKEA – the well known LACK tables at £5 each (£10)
  • Two packs of cabinet hinges from B&Q at £4 each (£8)
  • One pack of straight braces from B&Q at £4 (£4)
  • One small knob from Wilkinsons (£2)
  • Some grip surface – spare piece that I had in my workshop
  • Screws, Superglue – all from other projects
  • Two magnets recovered from a hard drive that was dismantled
  • One 4 bar extension from Wilkinsons (£3)
  • Cut sheets of 3mm clear perspex with holes in three pieces for fixing (£60 including all cutting and delivery from the Plastic Man).
  • Total cost: £87

This might seem like a high sum, especially the perspex, but they are large sheets at 890mm by 550mm x 4 – and close to £12 for delivery. The actual sheets were £12 or so each and were delivered on time and well cut and transported so a bargain if compared to similar online retailers. I heartily recommend the service.

Construction was simple:

  1. Glue down some non-slip matting
  2. Align the two tables and fix together with straight braces (2 on each leg)
  3. Align the pre-drilled screw holes of the perspex and carefully screw down (do not over-tighten as perspex will crack
  4. Glue hinges to the perspex door and leave to cure for 24 hours
  5. Screw door to frame.
  6. Forget that you need a hole for the knob!**

My only issue is that the tables were a little flimsy and not very accurately made (a <1mm difference in legs from the cut and glazing process) which coupled with some slight inacuracies of the angle of screw holes can give ever so slight deviance in the build. However for £5 it is a small price and easily correctable once we bolted the whole frame together.

The finished box is quite pretty (IMO) and site nicely on the side dresser where I have my specialist tools and electronic knick knacks. in the utility room of the house.

Once again a big thanks to the wonderful chap who is TBSliver for all of his help, advice, support and praise, greatly appreciated. LAMM members are wonderful creatures.
