Re: Help with 4PI / Reup
Dust, Thanks for your reply. When sourcing parts I did notice that Kliment has made a lot of expensive choices and its not surprising to me that the board costs more than competitors. It does bug me a...

I took one apart and had a poke around what is inside of the supply. The look quite decent for the price. So I would say go for it. [www.kurzschluss-blog.de]

Thanks for taking a close look at that PSu! I've been using the 12V 300W version (which is fanless) of a similar power supply to power my printer for the last 6 months, with no apparent problems. Was...

View ArticleRe: Duet heated bed max current
The standard bed on the Ormerod (which uses the Duet) takes about 10A. I wouldn't go much higher than that because of the size of the 12V terminals and PCB traces. There is an output on the Duet...

Perfect. I'm building a heated bed, which currently draws quite a bit, so I'll look at the Extfet pins. Is there any documentation for the DUET, I don't even know how you configure it or access the...
View ArticleRe: stepper motors and drivers compination
I think the torque of a stepper motor varies with the square of the current, in which case you will only get about 1/3 of the rated torque if you run those 1.7A stepper motors at 1A. Better to get...

Quotedc42Was the ripple really as much as 1Vpp? It looks a lot less on the scope trace in your blog entry. You are right, it is more like 0.2Vpp. I just had a look at it again, it is indeed only 0.2Vpp

Torque is directly proportional to the current. Temperature rise is proportional to the square. At the rated current into both coils the temperature rise is 80C, so for Reprap with plastic brackets we...
