Mending filament?

While I don't think this is easily possible I am wondering if it can be done. So my spool of filament had a tangle and got pulled into the printer head. Some got melted together and after cutting I have a few strands. Would it be possible to mend…

Marlin's bed leveling Mesh Validation Pattern ignoring home offset

I'm using a Prusa clone with Ramps 1.4, Marlin 1.1.5 and an inductive proximity sensor Z-probe. Due to the design of the printer, the X and Y end-stops and the Z-probe are not exactly aligned with the heated bed, so I must use Marlin's Home Offset…

Is a dual extruder a reasonable choice for all-purpose printing

I'm new to 3D printing and I recently got a LulzBot Taz 6 printer. I'm interested in doing dual extrusion printing (especially with dissolvable supports), but I'm also interested in doing single extrusion prints. In particular, I would like to…

Delta printer misalignment at first few layers

At first few layers, each layer has offset to -X/-Y direction base on previous layer. But above ~2mm, it is vertical. I've checked the printer build that there is no noticeable error in towers. Tried both manual calibration and Marlin auto…

How can I get PLA or PETG to stick to a glass bed permanently without adhesives?

3D printing gurus, I've read on several forums that people have had issues with printing with PETG or even PLA on glass and it sticks so well to the glass that chunks of glass rip off due to thermal stresses from the glass/plastic bond thermally…

What is the largest microSD card that a Monoprice Select Mini can read?

I have a Monoprice Select Mini v2 and it came with a 256 MB SD card. I have a bunch of 16 GB cards. I have made sure that the new SD card has a FAT32 filesystem. I copy the gcode file onto this card and when I put it in the printer, it can't find…

Where to find information on 'fast' or 'professional' 3D printers?

I work for a company that makes items from plastics. Many or our current runs are between 500 and 5000 copies, but knowing the company, if we find a good method to do smaller runs, they are willing to see if it is a good commercial option. At the…

Anet A8 reading 739°C from the extruder thermistor!

I accidentally let the print head of my Anet A8 crash into one of 2 clips that are holding a glass sheet onto the hot bed, and suddenly the screen went blank and the printer rebooted, then it started reading 739°C from the extruder thermistor. I…

SVG to STL conversion to make symbols recognisable for visually impaired users

I work on communication devices for people with disabilities that prevent them from speaking. This can be anything from a board with symbols on, to a relatively sophisticated app. Some potential users also have sight issues and have to…

Hot end jamming very quickly

I have built a 3D printer out of parts from my tip, a ramps board, arduino mega, and a hot end. However, after doing a test extrusion some plastic was spewed out and then the print jammed un-expectantly and my homemade extruder no longer had the…

Are there any methods of limiting exposure of hazardous fumes and odors emitted by heating the plastics?

When using thermoplastic-filament, this can be potentially hazardous, since constant printing can emit hazardous fumes and odors that may be emitted by heating the plastics. I understand it normally should be used in well ventilated areas. However I…

Wavy walls with Ultimaker Cura

I've printed a 2x2x2 cm test cube with Slic3r (left) and Ultimaker Cura (right) and my Prusa i3 derivative machine with tight belts. The print settings should be quite equal (0.15 mm layer height, 40 mm/s outer wall speed, default…

Small part bed adhesion

I am trying to print a model that has (at the start of the print) several small parts attached to the bed. Some of these parts have bed contact 2.5mm x 20mm. After a few layers, if there are any imperfections in the previous layer, the hotend is…

missing small sections of layers after a retraction

So I am missing small sections of a layer when it prints, after a retraction for a layer change or a move, the extruder stops moving (no it isn't clicking or anything else. Just not moving). Which is fine for a few millimeters because the pressure…
