One thing I’ve always struggled with has been printing overhangs and to some extent bridges due to inadequate part cooling. The problem is, with a monstrous hot end assembly such as mine, where can I fit a fan without losing too much travel in X or Y? My answer has been to exploit the fact […]
Around about this time last year, I was making a start on upgrading my printer to use a five colour Diamond hot end, in preparation for the TCT show. The upgrade itself went fine but I had problems printing five coloured objects. Specifically, the scaled up version of Aria by Loubie that I’ve talked about […]
Following my extreme retraction torture tests, I decided to upgrade my printer from using E3D Titan extruders to BondTech BMGs (five of them). This was quite a major job for many reasons and because………..well, on the basis that a picture is worth a thousand words, then a video must be worth more, so in the […]
This was my original method for holding filament Essentially two lengths of 2020 vslot extrusion spanning the width of the printer. Cylindrical adaptors (printed parts) of about 45mm diameter with a square hole right through the middle and with flanges at one end, were slid over the rods. Filament was loaded by sliding the reels […]
While exploring other things I was looking closely at gcode files and it occurred to me that extruder moves can be really tiny. Of course it’s obvious but it’s not something that I had given much thought to. A 300mm move in X generally has an extrusion amount associated with it in the order of […]
Really short of time right now so this is the briefest of posts just to say that I managed to get the Christmas Pyramid finished. YouTube video here – skip to the last minute or so if you just want to see how it ended up.
Introduction. As readers of this blog will know, I use a Diamond mixing hot end. For retraction to work with a mixing hot end, it is necessary to retract all loaded filaments concurrently. If just a single filament is retracted, then all that happens is that molten filament is drawn from one or more of […]
