Hello, 1. The two ports on the ramps board are actually both 12v; one of those rails is for the steppers and the hotend (5A) while the other input is for the heated bed power (11A). 2. What Stepper Drivers are you using? A link to the product page would be most useful, several pictures would be a close second. You can typically add external stepper drivers to ramps it will just take a little extrby Trexation - Printing
Tooling Plate works well, I use a recycled piece that it 13x13"by Trexation - Reprappers
I have noticed a handful of things, 1. Could the long heat break be causing issues? I have heard about heat creep with PLA and I think that could be related to poor extrusion. 2. Have you considered using a hanging extruder like This 3. Be careful about the cable that is hanging down to power your hot end assembly, it could knock a print off the bed. Good work and great job making a budget prinby Trexation - Mechanics
If you are using a pc power supply you could probably just take the 5v rail strait into the barrel connector on the arduino, but don't take my word for thatby Trexation - Reprappers
All metal hot ends from Chinese vendors have a reputation of being bad and failing after 1-3 meters of filament. I suspect that in a measure to cut costs while keeping the spec sheet the same tronxy used a trashy all metal hot end from china. If you have a good cold end then the motor would skip because it couldn't push the filament into the jammed hot end.by Trexation - Printing
Is it an all metal hotend, and if so what company (or lack there of) is it from?by Trexation - Printing
QuoteDust - Poor filament winding / filament tangling - Fumes from molten plastic And how do either of these contribute to noise generation? I find that poorly wound filament tangles, and when it tangles it suddenly overcomes the tangles area making a good deal of noise in the process. In multiple parts of my post I included making 3D printers more bearable along with less noise. Fumes, even fby Trexation - Mechanics
Greetings Reprapers, After building my first reprap, a Prusa i3 esc printer I realized a demoralizing flaw. 3D printers are loud to the point it make them hard to be in the same room with while doing anything productive. The most popular locations for 3D printers are in a workshop environment where dust is a huge issue, or a garage environment where climate control is non existent leading to issby Trexation - Mechanics
When you run m119 does it say triggered for your z endstop?by Trexation - Printing
It is sad to see yet another person falling victim to the E3D clones, just give them a bad review and buy a genuine E3D V6. the transition zone piece should not be spinning in the heat brake (Edited). Good luck getting it to extrude more that 10m of filament without a jam...by Trexation - General
If you give measurements that would be very easy to model, do you have a pair of calipers you could measure it with?by Trexation - General
Will it move up and down when you tell it to, is it just homing that is causing the issue?by Trexation - Printing
Quotethe_digital_dentist I agree, sand is awful, but what gets damaged? I think that it would depend more on the type of damage and the way it happened, but I have no idea what would go wrong first.by Trexation - Mechanics
QuoteVDX ... sometimes it's the ambient dust source - superfine sand is a killer If you are worried about fine dust you could go with a polymer guide like these from igus: Linkby Trexation - Mechanics
1. Have you seen the magic smoke from your ramps board? It could be that the mosfet is broken 2. The thermistor could be disconnected; make sure that it reads about 100k ohms at ambient from plug to plug. 3. Does it just start heating up when you apply 12v power, or does it heat up uncontrollably when you tell it to reach a certain temperature?by Trexation - General
It seems as though you need to change endstop inverting to true, that should solve your issuesby Trexation - Printing
Is it a repstrap? mechanical issues can cause that too..by Trexation - General
I used compressor shock absorber things for the feet on my printer, but your solution seems far better... Link to padsby Trexation - Reprappers
Onshape is completely web based, all it needs is a browser that supports openGL... Onshape Websiteby Trexation - General
Have you tried Onshape as a CAD solution? it is fully cloud and web based so it could probably run well enough on your pi assuming it has a good internet connection.by Trexation - General
It could definitively be related to belt tension and the flexibility and quality of the old belt vs the new one.by Trexation - Mechanics
1. That inductance seems a little high.. but otherwise they look good to me, 2. Don't forget about the extruder stepper depending on if extruder includes one. 3. Make sure you have decent electronics to push 1.7A, cheap Chinese DRV8825 should cap out somewhere around there 4. Another great post about motor size Hope your delta build goes well!by Trexation - Mechanics
Ok, I totally understand; I hope your crowd funding campaign goes well.by Trexation - Mechanics
Can I get the CAD model (in Step or iges) please? I would like to dissect the design for possible use with a large printer.by Trexation - Mechanics
Your welcome, I just don't want you to make the same mistake I made, spending $25 on a bad hotend and then another $40 to get a new one.by Trexation - Reprappers
I would start with the genuine e3d hotend then go for the titan when you have the money.. I have a greg's wade reloaded extruder and when I first started printing I was using a cheap ebay clone hotend and I couldn't finish a 30min print without a jam. Once I got a genuine e3d metal replacement parts kit it started working flawlessly, I have not had a hotend / extruder jam yet. Please don't buyby Trexation - Reprappers
all the ebay ones are worth their weight in dog crap; I bought one once, now it sits in a drawer on my desk.by Trexation - Reprappers
Looks fine to me, good luck.by Trexation - Reprappers
Have you seen the e3d titan extruder? If you plate is more than 2mm thick you could use that in place of the mounting bracket.by Trexation - Reprappers
