What materials need >300degC print temps?
For my own curiosity, and to avoid me digging, do you know how smoothieware sets current to each stepper? I'd be interested to see how they do it....
Hmm... If we're doing apples for apples, china based suppliers are cheaper than you mentioned. 3D Printer kit 1pcs Mega 2560 R3 + 1pcs RAMPS 1.4...
I'd say go with RAMPS 1.4 purely because its so cheap and common. General rule of thumb is that any cartesian printer is more than easily handled...
Yer probably should have stipulated that i was referring to mechanical relays only. The other points about SSR's are still valid though. Another...
A mosfet is functionally similar to a relay, in that they both switch a connection with an electrical signal. But they have no moving parts to...
I'm glad someone has noticed this. I too have steel-reinforced belts on the XY. I almost always leave my print head in the home position when not...
Yours is a FOTEK one from some chinese merchant right? They're dangerous, for exactly this, and more reasons. RS and Farnell in the UK; and...
JST connectors (assuming you're talking about those poxy little white PCB mount style connectors) are rated at approx 1.5A if memory serves....
I personally think google groups are a horrible format for anything other than public-facing email chains, as that's effectively what they are....
Don't mean to be a party pooper, but I'd argue some of those traces look too close to be safe at mains voltages. In the UK. (230Vac mains) Mains...
Thanks Carl :) I agree with you regarding the non-sprung idler arm on my previous design. It's difficult to judge the pressure on the filament...
Hi all, Sorry about the wall of text. I've been using my own design of a simple bowden extruder for a while now with my C-Bot (V/T-slot bowden...
An RRD fan extender will be fine @ 24V if i've ID'd the chip correctly :) I have one myself at home, and will double check the markings on that...
No worries man. Least I can do in comparison to all those blog posts! ;)
Your kill a watt measured 4 amps with a 120V supply is equal to ~480W. Your bed is 12V @ 20A = 240W Your hotend is 12V @ ~2.5A = ~40W (assuming yo...
You mentioned your SSR switches at a lower frequency than you set in your software config? I thought it might be because your SSR was delaying for...
That change from 1Hz to 0.25Hz is most likely not to spec. FOTEK's from what I've just googled are 10mS switching delay for zero-cross detect. My...
Just skimming through the past month's posts... I can save you the work. I previously converted almost all the parts to .STP, and around half to...
+1 for PETG. I and quite a few others printed our parts using it, and it's very strong.
