If you manually stop a print, then send a retract command (there is a button in repetier) of say 10mm: otherwise you have the "pressurised" filament cooling (slowly) into a thick plug. The retraction is not so much to get the filament out of the hot end, more to reduce this pressure. Even on the E3D I have noticed this on aborted prints.

My motors also get pretty hot, but I haven't bothered doing anything about it. If you do want to adjust the voltage to them, there is a vid tutorial in the support tab (for printrboard it is manual pots on the board, form D8 it is software (gcode) controlled.

I've got the 5D board & after a quick search found another post of yours explaining how to lower voltage through gcode, so thanks for that I've also found that whilst I've not managed to get another print to get any further than 20 layers, the 'retract 10mm after stopping' suggestion has been a great help.

Went to order the E3D hot end & it wont let me even pre-order it.
Guess I've just gotta keep checking back to see when it's in stock

More progress. Today there's been a nice breeze flowing through the flat.
Figured I'd try printing something different, but still simple.

I had a go at the anti- z-wobble-part-thing
(http://www.thingiverse.com/thing:330307)


Came out great I think, compared to most previous prints (by that I mean im just thankful it completed without jamming)

Also re-tried the first of a literal handful of parts I want to make.
I have some pretty decent STL files for the fingers of an Iron Man hand that I want to eventually print.

It jammed, but this fourth attempt is the furthest its got so far:

Chris, first off, remind me if this is PLA? also, poor bed adhesion will give all sorts of problems later. Try printing with a brim.

I've never had many issues with adhesion to the bed, if you're on about the top pic (the z-wobble thing) its meant to be like that. It's got a slight overhang on it & worked better than expected.

I have however had issues with the filament not coming out consistently, leaving little wispy waves of filament instead of a straight line of it & not adhering to the layer below as a result. I figure this is either a Slic3r issue, not putting out enough, or just general extruder/hot end issues, which should hopefully get fixed when I get my hands on a E3D hot end.

According to the mighty Nils Hitze, they have stopped pre-orders of the V5 hot end as they're transitioning to a new V6 design, so I'll have to wait a bit for it. Hope it's not too long. I wanted the V5 'cos there is already precise tutorials on how to add that to the MakiBox. I may be quite technically minded, but when it comes to hands on electronics I'm a bit useless

sounds like either something blocking the head or possibly E-step is wrong.

...aaaand another hot end dies. One left.

They better bring the E3D V6 out soon or I'll have nothing to print with :/

this is way beyond a joke. It sounds like the new replacements are even less reliable than the originals

Sadly I think they are all as bad as each other, which is a shame.
I generally like the design of practically everything in the MakiBox A6.
There's some great ideas in there, its just a shame they don't actually work.

I'm curious what they plan for their next release?
Could there be a more refined A6, or a whole new design?

Either way, I doubt I'd be buying it unless there is proof they will ALL work right.

The original design can be easily fixed by getting rid of the press fit and using a disk spring to clamp the heating element. Assuming they can come up with a spring that won't anneal out at up to 250C.

Sticking to their guns on pressfit will solve nothing, IMO

WOOOOO.

Finally, they just released the E3D V6.
Within 10 minutes of the release, I've already ordered one for Susan.

E3D v6 looks good. Price a bit steep? I posted about this is the News section of the forum to hopefully get more attention. I bet you're not the last to order here but you are the first!

Good luck

Still the same price of previous models, and as far as I care, it's a small price to pay to get a functional printer.
Especially as my third & final stock MakiBox hot end died yesterday mid print.

Yay! It's been shipped out.
My E3D-V should arrive tomorrow

Next step? Figure out how to make it work with Susan

Very nice Cris. I ordered a VI, but I got an email saying that mine will be on a few day delay before shipping.

Definitely post your results!
