Geoff's Mini Kossel Adventure

[Geoff]

Nice printer, Liking those Black aluminium bars, How did this kit cost anyway?

Ive been thinking to get my printer all taken apart and making a Delta, But aint sure yet at this moment.

They look damn awsome and have some nice speeds without to much vibiration nor sound.

if you bought the parts seperately, about $400, but in a kit with everything ready was about 600, but now I know what's in it and what I can get parts for, it wont be anything near that price.

#1 most expensive item is the bearing sliders for the arms, from $50 onward each... i see now why people use V-slot runner wheels instead ...

The aluminum bars are $18 for 1 meter, I bought 10 meters, but you need to calculate your grinder size as you will lose like 3mm per cut, the black are like out of stock everywhere .
M3 screws are much required in this kit, there is 16xM3-15 in each base foot, 5 in each top..

Allen key / spring / safety pin / endstop microswitch makes up the autolevelling feature..

Traxas rod ends and graphite rods so easy to get... everyone has got them...

The speed is unbelievable from what I have seen, for me it means double the reliable speed at 150ms feed rate.

That looks very good. I am curious what is the build volume supossed to be? 300mm footprint, in my mind there is around 200mm cylinder capable? How about height?

My round glass plate that came with it is 180mm, but I have a boroscillate round glass at 170mm and a 160mm round hotbed, so will prob use the 170mm.

I find height is what I want more, and the kossel mini is rated to 240mm high prints! so I will have a print area of 170x170x240

That must be one fast beast. Are you looking into light weight build for the head? I have an idea of making the carriage and the hot end one part. Should reduce the number of steel fasteners and reduce the weight drastically. IF your printing in abs, use abs carriage, if your printing in pla still use an abs carrige. My pla parts warped after 2-3 prints.

I went oversize with my build and I am using abs, this means the main moving parts are like 2x the weight they should be, maybe more. Tuning and tweaking is next. I am liking the alu extrussions. I will be experimenting with a different rail system once I have my heated chamber built. I printed a 220mm long part yesterday. It took about 12 hours, and at the end I had some ridiculous lift on the edges. The part is still usable as it looks like a uniform lift, but the part warped 3mm on each corner. I have to get a heat spreader and heated chamber built asap or else this thing wont be able to do the rest of the parts I need.

I have to admit. it's the first machine I've used/built that has a feeder external to the head. I have never really liked the idea of feeding the filament from half a meter away from the head. I am keen to try it to see how light it makes it and if they makes much of a difference, all I can go on is youtube videos so far and they look great

I would love to say I used a couple of machines to print my kossel parts, but the only one I could get the corners to print without warping was the flashforge, with 50% infill they take a long time to print need a fair bit of heat.
