Re: working on slicer in blender

tl;dr I wrote a voxel based slicer that handles surface color and converts it into a shell of arbitrary thickness along the point normals. It outputs RGBA image for ink jet printers and G code for FDM. It's 25% done: https://github.com/MatthiasWM/IotaSlicer Long version: I have been dreaming of a UV...

Re: Hacking the Xaar 128 printhead

Water will short out the pizzas and kill them. Once you run the head with water, you can basically throw it away. You should only use Xaar sanctioned ink and cleaning fluid, and purge the cleaning fluid using a negative pressure on the nozzle size and pull fresh ink in before running the head again....

Re: Hacking the Xaar 128 printhead

Xaar 1288 heads can not deal with water in my experience. You need inks that are in the Xaar compatibility list. I assume that the conductivity has something to do with it as Xaar heads are piezo heads, physically squirting out the ink vs. thermo heads that basically boil the ink. I assume that cond...

I used the cleaner that came with the oil based ink that I ordered.

Re: Site changes

Sorry about that, and thanks for your patience. This is so annoying. We get registrations as new members of our not-for-profit club every day from non-bot, only to put a link to a porn site into the payment text field. I really don't know what they think they are gaining here.

Re: New project powder 3D printer ZEUS

Different powders compress at different levels. You should not compress the powder in the funnel, or it will not flow. The powder around the finnished model is quite compact, not physically compressed, but still dense from rolling it on. For plaster, I'd guess it's 110% to 120%, for sugar, I'd guess...

Re: Hacking cartridge HP 84/85

After having helped you over the last 16 pages, it would really be nice to get a little bit more information on the protocols and timing. I'll check the most recent pinout, but I am pretty sure that this is not enough to replicate your success ;-)

Re: Generic powder machine controller

That's very nice. Your slicer is on my support list. I'm wondering how far your slicer is to produce image files instead of gcode? This is a volumetric slicer. The models are handled as voxels. Layers and slices are images. Images can be written anywhere in the process. It's as simple as adding a s...

Re: Generic powder machine controller

Iota https://github.com/MatthiasWM/IotaSlicer is by no means complete, but it is an open source texture slicer. The texture functionality is currently disabled because optimizing voxel code had priority for a while, but the source code is still there. There is an improved texture slicing system in t...
