If circles are coming out as oval, I’d first check the belt tension to make sure they’re all tight. Id check the stl files also and make sure the dimensions are correct. If its oval then it means one axis is out of whack. Print a square and check the measurements but mark the orientation. If one sid…

In the menu there is an option to enable the second printer head.

I whole heartedly agree. There are indeed differing levels of 3D printers on the market. when I bought my CTC, I could have had a cheaper option like a Prusa I3 which required much much more assembly, set up and calibration. OR I could have gone for the much higher end of the spectrum and got a st…

To be fair, the default extruder with a fixed bearing and no pre-load is terrible. I bought a moulded abs spring loaded replacement pair of extruder on ebay, best upgrade so far. I plan on getting some stainless bar and making my own barrier tubes on my lathe so that I have an all metal hot end.

You can’t run without the PTFE tube. It acts as a guide down into the nozzle. If you run without it, the filament will just flex in the heat break, twist and jam. The only way to get rid of it completely is to replace the heat break with to a version with a 2mm hole down the centre and nozzle with …

That’s the PTFE tube, 3mm OD 2mm ID that serves to prevent excess heat transfer too the filament that is in the barrier tube, stops it from melting too early into the nozzle. Looks like that you might have been running your hot end too hot and it’s melted the PTFE tubing. PTFE has a melting point a…

This is true in part, so long as you use good quality PTFE tubing, your looking at 260C for maximum operating temp. So long as you never reach that or close, it should last but should be considered a consumable. I’ve actually replaced my PTFE lined brass nozzle with a solid metal nozzle so I’ve got…

I could probably spare some as well should you need it. I’m likely never going to use it all!

I tell a lie, this is the one I bought and paid twice as much also!

Id beg to differ. I used a piece of 3mm glass from a photo frame for a little while. It shattered one day and made a real mess of my printer. That cost me 7 quid. Few more quid and I could of had a proper piece of borosilicate glass. To be honest, using plain glass that isn’t designed for thermal ch…

Wanhao uk have a supply for about £20 on ebay. I bought mine from China on aliexpress. Was about £13 with free shipping and very well packed.
