Update 28: Replacement parts

[pelgrim @pelgrim]

The good news is that we have already have a solution; the ‘fix’ is just being prototyped and tested, and we hope that over the next week or so the replacement parts will be produced. These parts will then be sent out to everyone who already owns a Robox to retro-fit.

That means it’s advisable to wait printing until we have the replacement ?
It’s really no problem for me, just need to know.

Hi Pelgrim, I guess the sensible answer is to keep an eye on it as its printing and hopefully it should be ok. I’ve just finished an 18hr print overnight with PLA (with the new extruder on my beta unit) and not experienced the issue.

Although I have yet to receive my Robox and haven’t seen the extruder I can imagine how the bowden tube is mounted. My suggestion: until the replacement part arrives, temporarily secure the bowden tube where it meets the “plug” with a tight cable tie or by twisting a wire around it.

Time to break out the safety wire pliers!

It seems to me that the old way either worked or didn’t. The first few tubes and fittings I had popped at the first glance. Then it was stuck so firmly it was nigh-on impossible to remove the tube. If this is the fault they were encountering, then most users would never tell the difference. For some, however, it’ll make all the difference.

In other words, don’t stress about it. If you need it, you’ll know. Or at least you’ll know when you come in one morning after leaving it running overnight and will find the Robox gestating a gigantic ball of twisted filament.

I don’t know how much filament is used in an average print,
but I don’t like the waste of filament.

According to the stats output by AutoMaker, one of those standard pyramids at 100% (same as I did four of today in another thread) uses around 80cm of filament (volumeUsed/2.4 /1000 = 2000(±100)/2.4/1000 =~ 0.83m) That’s for an hour long print. So, maybe an overnight job takes 5 to 10 metres? A Robox reel contains around 240m.

Incidentally, a Robox reel is £24.90 ABS, £26.60 PLA plus shipping / 240m; so that’s around £0.09 (€0.12, US$0.15) per pyramid, ie. per hour on 50µm, 40% fill.

So that’s something like £2 for an overnight job. Hang on… that doesn’t sound right. Seems like there’s an error in my calculations somewhere. Even so, it’s unlikely to bankrupt you or cause massive ecological damage. If you’re worried about that, get a grinder and a re-extruder.
