I have been longtime fan of getting myself a 3d printer but they were way too expensive usually. Then I stumbled upon Tom’s youtube vids on dolly. Big cheers for those
Anyhow. Now that I have finally managed to scrape all the pieces and build the damn thing, I seem to have hit a snag… When I tried to pidtune my hotend, I heard a pop and whole printer went dead. (Not the arduino mind you, just steppers and such).
Since going budget was quite the sales point I did just that and seems like I might have gotten some shoddy chinese quality.
And then the problem.
I presume it’s not quite right if I measure resistance from heat cartridge leads and it shows 0.7 ohms, kinda think this is the culprit that blew my 5A (?) smd fuse from my biquitech “1.6 ramps” board… Not sure if it caused more damage on that board among that fuse… Assuming I didnt fry the ramps board, should be fine just replacing the fuse right?
Now another question is, since it’s still quite a tight budget… I need working cartridge to replace the faulty one… Any tips where (in Europe) I might look for one with modest price (and postage that doesnt double the fee), destination this nordic wonderland of Finland?
I could always go back to aliexpress or some other chinese site and get one. But I’ve kinda talked about making a blog post(s) on building this printer to my school friends and I dont really fancy waiting another 2++ weeks for a part to arrive from asia…
Oh and third question, since this 1.6 ramps board only has one input for power, is my 16A 12V atx psu enough for driving a printer or should I look for some “real” 20A++ psu?
