Re: Modular 3D Printer Project - 8 years ago

A stable box frame with ballscrews that can be driven with servomotors would also be a good project. The servos are expensive but that would allow fast printing and strong cnc'ing.

Re: Modular 3D Printer Project - 8 years ago

What exactly to you mean by cartridge? a toolhead that can be switched easy? Can you put everything I one 2x10 connector. Tom Sanladrer (YT) has mentioned making one plug/connector for all his machine so he can swop different hotends incl cooling and z probe. Q1: The cnc incl pcb drill needs a cnc frame and thats why you see so few "swappable toolsheads" on 3d printer frames. Lasers might be "fu

Re: New Delta Project - 8 years ago

@etfrench: yeah that tape sounds like a good idea. at times I put in oiled paper tissues, that work decently. Ill give it a shot in my next arm upgrade.

Re: New Delta Project - 8 years ago

Printing outside the towers. Has that actually been done successfully? I thought about that when I planned my delta 2 year ago, but I had trouble finding joints that could move more then 60deg reliably. My traxxas joint where working well and my frame oversized so the area inside the towers was enough for that time. I also bought magnetic joints but the magnetic ends started to scratch away the

Re: He3D Delta DLT 180: Power In Plug Melted / Glowing Orange! - 8 years ago

This a common issue and the reason why lots of people are using relays to power their beds. The whole power supply circuit for the bed is undersized on the ramps (connectors and mosfets). Measure you the actual power use of your board and compare it to the ramps ratings. Since the boards are so cheap now, I would replace it to be on the safe side. Or try this

Re: KOSSEL mini G28 issue - 8 years ago

Are you getting any min temp errors? those would stop the motors right away. -individually testing the motors on each driver might get you some insight. -Is the extruder working and the axis motors not? and always turn the power of before unplugging the motors, to protect your drivers.

Re: Fail-safe tube fitting - 8 years ago

Interesting! How does the little bead "clamp" on the tube? and how did the store describe this item? Im looking into stronger bowden couplers atm to increase print speed so im developing this double coupler, but a simple metal piece is of course nicer to work with.

Re: strongest bowden coupler? - 8 years ago

The math you did is roughly what I tried and came up with as well, but the upper end of the extrusion limits are not very well defined by the manufactures of the components. I tried e3d and bontec to give me their test data but all they gave me are theoretical values and not proper experiments. In addition the 3d solex nozzle increases the heatable area inside the hotend enableling much more heat

strongest bowden coupler? - 8 years ago

Hi, Im testing some high speed/ high volume printing at the moment with a bontec V3 extruder, a e3dV6 and a 3d Solex 1.5mm matchless nozzle. Everything works fine so far when I print .9 layerheight with 1.8mm width at 15mms, however the parts thats actually giving in when I push past 20mms is the bowden coupler. I already reinforced the e3d coupler with and additional m10 screw coupler on top b

laser resistant sticky/glue foil - 8 years ago

Hi, I need to keep a lasered design with many parts together and I dont want to design connection bridges. Is there any sticky material/foil that can resist the laser when its glued under the main material? For a weak red diode laser I can imagine a red sticky tape under the main cutting material that doesnt absorb the laser so all parts stay stuck to the foil but the foil itself isnt cut.

Full color resin printing? - 8 years ago

high capacity nozzles - 8 years ago

Hi, I recently talked to the bondtec people extruder about high capacity printing and they recommended this guy http://3dsolex.com/matchless Its supposedly a new way of internally designing the nozzle to improve heatflow. I havent fully grasped how better heat distribution can achieve those speed increases, but I thought to just leave this here to be dissaminated Cheers

Re: Why Spindle driven Delta's are more precise than Belt Driven - 8 years ago

Re: Volcano 1.2mm nozzle extrusion fail - 8 years ago

True I didnt pid tune the big nozzle extra but i also didnt see any temp jumps. Im thinking of putting in my old wades extruder to make a comparison test.

Re: Volcano 1.2mm nozzle extrusion fail - 8 years ago

I tried 200% and the brought back the blobbing. so somewhere around 15mms the max speed lies. and i tried various first layerheights that didnt seems to influence the pattern

Re: Volcano 1.2mm nozzle extrusion fail - 8 years ago

Update: I started a print with 10mms and then inscreased speed up to 150% with no visible errors or blobbing in the extrusion, ill try pushing it to 200% today.

Re: Volcano 1.2mm nozzle extrusion fail - 8 years ago

I see, although it seems to me that the the blobbing that comes out is way more extreme than any stepping issues that could come from the motor. and it would mean that it should start right away not delayed like it does. Also the feed feels fine, if there are some steeping issues I would feel them on the motor and definitely on the filament feed, which is smooth.

@stephen can you expand on that piston pump concept?

Re: Volcano 1.2mm nozzle extrusion fail - 8 years ago

Interesting, I decreased the speed to 20mms and now it looks almost normal. I still dont understand what could cause a pulsating pattern like that and it doesnt look like underextrusion /too high extrusion speed.

by sungod3k - Reprappers

Re: Volcano 1.2mm nozzle extrusion fail - 8 years ago

I set the speed to 30mms and i have a bondtech double drive gear extruder, so that shouldnt be an issue, and I used the big nozzle on my geared wades extruder before without problems.

Volcano 1.2mm nozzle extrusion fail - 8 years ago

Hi, I recently strapped my e3d Volcano nozzle on my printer again and tested the 0.6 and 1.2mm nozzle. and while the 0,6 worked very well, the 1.2 is showing some interesting extrusion. As you can see the first 20mm (middle of the picture) are a nice thick bead, perfectly squeezed out, but after that it almost starts blobbing. The filament feed stays constant and the same pattern emerges in C

Simulating FDM prints with finite element analysis - 8 years ago

Hi, I was just playing around with a replacement hinge for my fridge and going just by experience for deciding how thick to print the whole thing. Being already in fusion 360 I quickly ran an FEA with an ABS and an unspecified "plastic" material, which yields some results that dont look to bad, but of course the program assume solid materials. Putting aside the print direction one could of cou
