Yet another filament guide

Yet another filament guide.

I didn't like the look of several I found here, so quickly designed my own, it's for the HICTOP Prusa I3 Aluminium frame. It clips onto the 20mm x 20mm frame, and includes a gap for putting the filament in after you've already inserted it into the extruder.

Fostex Fe126En Grill/Cover

This is the frame for a grill that is designed to fit a Fostex Fe126En and many other drivers that have a square frame that measures 117mm by 117mm.

Neje Laser Engraver Front Tinted Cover

Using the neje laser printer in a small room can be very bright to the eyes, so I made some mounts that bolts onto the frame using longer M3x15mm screws
Buy a piece of tinted plexiglass off ebay and cut to fit, now you have a shield from the harsh laser light.

TLDR: the guys that I caught showing heavily processed prints from different types of machines and claiming them as unprocessed prints from theirs at NYMF have now been caught ordering prints from Shapeways for the same purpose. I predict this will be the new Japica.

Looks like Full Spectrum beat Glowforge to market with an incredibly blantant rip-off of their design...

La Grotte Du Barbu

Construction d’une boîte en plexiglass pour mes jolies cartes de visite – Ep173 – PlexiCartes

Cette semaine je tente de fabriquer une petite boîte pour stocker une dizaine de mes nouvelles cartes de visites pour éviter qu’elles se salissent au fond de mon sac.
Pas win, pas fail non plus, appris beaucoup de choses

un petit lien vers la colle magique de chez Crimson Guitars qui est trouvable ici (et qui est juste géniale)

Flattr this!

Tales of a Pi Installation

With the new mount in, I needed to upload new firmware - even though slic3r can take a Z offset, it seems the heating position doesn't take that into account and just goes to Z min, which is now about 7 mm below the plate.

Unfortunately, new security software on my laptop blocked some of the sub-programs used by Arduino, so I figured it was time to switch to the Raspberry Pi I got for the same purpose. Hook up a monitor, a (German) kezboard, and a mouse (I am still amazed that you can plug in random things in USB and they just work and know what they're supposed to do), and up and running.

Except not quite. The Arduino in rpi is rather old, so I decided to try a new one with proper board management and all, compiled from scratch. Took a while to install all the dependencies and everything, but I got it. Except... the Marlin firmware isn't compatible with Arduino 1.5+ :( So back to the old one (with an interregnum of a Chromium update making it fail and requiring a kernel update, and various crashes when I asked too much of my little Pi).

I did update to a newer version of Marlin, though getting that to compile right was tricky. I don't have the Melzi definition installed and remember installing it as a frustrating task, but some sites say Sanguino works as well - and it does! (Specifically ATMega1284p 16MHz). I set the Z_MAX_POS to 200 but allow it to go to -1, in case the frame expands. The Z axis is exceedingly slow, though, until I changed the steps to 200.0*16/1.25 - that's what I had before, I'm honestly not sure where the calculation comes from. I might be able to speed it up... nope, that caused a crash! I'll keep it low.

The bed height when manually calibrated turned out to be 1.1mm above 0, a bit higher than I hoped for, so let's reduce the height to 199mm.

The newer firmware version seems in particular to have better autolevelling support, which I want to include soon. Also, it connects immediately rather than after about 5 seconds, which is nice.

I also need to recompile Slic3r, of course. And somehow it seems every app involved uses a separate set of languages and libraries, so each time I install something 20+ other things get installed. Sigh. But the strangest thing will have to be this requirement for Slic3r:

I was not done with those! In fact, I just specifically installed libwx-perl to make Slic3r happy. I'm sure stuff is going to break stuff. And it doesn't make Slic3r run, it wants both wx and opengl, but those two cannot live together. What's with that?

Huh. Despite setting the height to 199mm, it still hits the bed at 1mm Z height. Maybe that's because I didn't actually change it.

It seems sometimes the Z movement is a lot slower than normal. It would be nice if Pronterface had a display of what it thinks the state of the world is - where the axes are and how fast they're moving.

Truly, language-specific package managers are a pain, a pestilence, and a pox upon the Linux world. To get slic3r to run, I've been led a merry chase between installing Debian packages, installing CPAN packages, installing Debian packages because installing the CPAN package failed without it, running slic3r again to find another package is needed, etc etc. Only to get to where slic3r runs for two seconds and then segfaults.

This is probably caused by, and can be cured in the same way by not having the plater. I only occasionally use the plater, so that's ok.

Since I don't feel like digging up the standard (if any standard exists) way to install a Perl program, I'm just pointing at the build dir for now, so my slicer command is /home/pi/src/Slic3r-1.2.9/ --gui --no-plater $s --output $o  --load "/home/pi/3DPrint/Slic3r/filament/Simple Mode.ini" --load "/home/pi/3DPrint/Slic3r/printer/Simple Mode.ini" --load "/home/pi/3DPrint/Slic3r/print/Simple Mode.ini". Slic3r is a rather quirky program, all told.

An unfortunate side-effect of switching to a Linux system is that I can't use Google Drive as my shared filesystem any more. But I can mount my home directory from my main machine, which in turn contains a Google Drive mount. Using afpfs, that was pretty simple, except Slic3r without a plater doesn't automatically slice like it used to, so I have to "Quick Slice and Save As" until I find the right commands. Update: No, I just needed to remove the -gui argument.

Trying to print - and no heat. I probably missed a thermistor setting. Or not - the hotend thermistor is definitely the right setting, and setting the bed to something that looks sensible (some numbers have changed) gave wonky results. Trying again, they both heated.

Now I got it to print (with a cold bed), but oddly the print was done a full centimeter above the bed! The new firmware is nice, though, that it heats the bed and extruder while homing. Much time saved. The print is absolutely 9.95mm above the bed, desipte the settings saying Z offset of 0. Odd.
