A couple of 3D printers turned up on that HotDeals site over the last month for between £130 and £200, now there getting down to consumer level money, I was tempted, what I fear though... a crap load of issues and I sadly don't have the time to mess about for days :(

It also end up like most things use it for 20 mins and forget about it :lol:
Its like I really want one now the price has fallen, but can't justify why :lol:

Thats why I got a flashforge dreamer, I just wanted to print stuff not mess about.. Even though its taken me a while to get to grips with all the settings, at least I didn't have to worry about the hardware side of things. I pretty much unpacked it and printed the test object right away.

Not that I have much experience, but I guess, 3D-printing is still something quite hobbyist. There are machines that you just unpack and start printing with, but if you want good quality prints, you will have to pay for it. Either with time and effort to fine tune a cheaper machine, or with money to a company that already did that for you.

I will. Still not satisfied with the calibration of mine, a problem you would of course not have if you buy the assembled and tested one instead ;-)

I LOVE my Prusa MK3s - bought it to print keyboard mounting rails for my Amiga 1200 mechanical keyboard project but since I have found so many more uses. Most recently to print threaded adapters letting me plug generic wire-reinforced vacuum hose into my workshop cyclone/vacuum system. Out of the box it works well but I upgraded with the Slice Mosquito/Bondtech drive hot end, not a single jam since doing that.

If you print PLA - use the non-stick smooth sheet it comes with. If you print PETG then make sure to buy the textured powder-coated sheet. Before buying the second sheet my PETG prints damaged my smooth sheet a little, it sticks far too well and made some marks in the surface. Since using the right sheet for the right material no more damage to either and every print sticks and releases when cool just as it should. Be careful to wipe only with isopropyl alcohol, you do not need acetone or glue sticks if you keep it clean with the right chemicals.

I also definitely recommend the IKEA LACK enclosure that Prusa hosts a design for. I made mine from two tables, double height, so that the filament is enclosed inside but once you have this you will never worry about warping or lifting prints due to cold or draughty conditions.

Mine was a smidge under £100, but came as a flat pack which took around 6 hours to assemble! if I follow a process during printing, normally it isn't problematic.

My main problem was my Cura settings not importing quite right when I changed laptop, which caused some chaos.

Okay, first layer calibration took me a really long time. Not because the printer had an issue, but because I found it quite hard to see the difference between too thick and too thin layers. At least this was the case after only reading the Prusa manual.

These links made it a lot clearer for me:

Very good explanation and some close ups of how it should look like:


Some additional close ups, how it should look like on the poweder coated sheet that I have:


A download for a 75x75mm one layer sheet too better see the diferences

Six smaller sheets to check even distribution all over the printing bed:

Hope this helps others :)
