Re: compare 8 bit to 32 bit printer controller
Delta printers are supposedly pushing the edge of 16 Mhz CPU performance, due to the complex calculations they need to do. The current crop of popular 8-bit controllers are obviously fine for a...

Hi Vreihen, many thanks for your answer, probably i did a mistake because i bougth a duet board plus expansion. As you know is a 32 bit. What's your opinion about this board? My design is cartesian. I...

One good way to go may be using a fairly large toroidal transformer.. something like this: [www.mouser.com] followed by a bridge rectifier and large capacitor. After this basic circuit, you can build...

I don't know anything about that combination, other than that I think Repetier's firmware supports it as one of the DUE family boards. Is there a Marlin build for it? I don't think that any board is a...

Hey there! How can I find out how the board matches the pins configuration/assigned numerical in the pins.h file? Trying to move the heater power down to D9 on the ramps board. Sincerely Janski

What logic is the pins.h file following? Is it getting the numbers from another sub folder? Still new at this and having a hard time manipulating pins.h file:(

Is this what you want? If so, Just swap the numbers.

That's the sort of behavior I got from one of my stepper motors when I cranked up its speed too much. Very short moves worked fine because the acceleration value kept the motor from ever hitting top...

Hello everyone, I'm new here. I am interested in building Prusa i3. As I looked around, I found everyone using Arduino MEGA with RAMPS shield for controling motors. Maybe anyone knows if RAMPS would...
View ArticleRe: Ramps 1.4 to pins.h: need help!
Yes! Thank you for the explanation. I was changing the heater pins instead heater and fan . Is there a map that explains the pins.h related to the board itself? For future experiments:) Sincerely JANSKI

Hi Zairus, if you need 2 for every Axes (X/Y/Z syncron) you can design a y-cable (for x and y) 32 bit is NOT strictly nessesary for a normal cartesian, but ... In Future it will be availible the 128...
View ArticleRe: Arduino UNO for controling?
Uno won't work, not enough IO pins. The Uno has 14 digital pins which can't support 4 steppers (3 pins each) plus 3 end stops. This is before you add anything else you might want to use. The Mega has...

Well I've progressed a little now but in some ways not. I managed to damage the extruder assembly by getting it too hot, and it had been printed in PLA instead of ABS so it wasn't too pleased and...

Oh terrible news about your extruder...good thing to have friends around..:) Regarding PLA, acetone (with dissolved ABS) does not work with it. ABS juice is only for ABS. A good solution mentioned...

You can also try print PLA on glass, that is if you can find a small piece of glass. And perhaps double check the acetone label, if its that type of acetone for removing paint from finger nails, it...

Thanks guys Sorry, when I mentioned acetone I meant just using that to wipe the bed clean, not using ABS juice. I should have been more clear. Not sure re the label, it was a gallon I bought when...

From my experience PLA on glass should be a quite reliable, even more if the bed is heated mildly like 50-60C - if glass on heated bed reaches like full abs temperatures the glass may crack and break....
