After looking into it some more, these are the options I've come up with: [*] L6743 [*] FAN3100 They're both in a similar price range and they are real MOSFET drivers, not just high speed current...

Hi guy! I have on order a bunch of rotary encoders (20 steps) to use on a LCD controller for Ramps. Then I thought, could I use the center mouse wheel, it can scroll up and down and accepts a click....

I'm not sure if I can make the space for that. I did add the two pin header next to the 6 pin ICSP header in hopes that it would be compatible with Sanguinololu add on sd card boards. I haven't tested...

Thank you for the answer. I will read it very carefully and if I'll have more questions I hope you could answer me again. Also this are my stepper data: Weight:0.4kg 2 Phase Skidproof Shafts Step...

If i am not mistaking for your values and 12v psu it would take ~0.0010779930014654s for current to rise to a set level of 0.5A. On the other hand the motors from this post datasheet would need...

I'm not experienced with these matters "yet." But i have a new from China Arduino Mega, Ramps 1.4 and a set of a4988s. So I don't blow anything out can someone give me some rudamentary steps to...
View ArticleRe: Checklist for testing out new electronics
In the Arduino s/ware, there's a simple program you can upload which just makes an on-board LED blink - that should be a fair test of the board. You can't do much really with the Ramps until you've...
View ArticleRe: problem x-axis Gen7
You could flash your board with the 'blink' sketch from the arduino IDE, edit it to use the pins associated with your x axis motor driver and use a logic probe / volt meter / led to check if it goes...
View ArticleRe: Checklist for testing out new electronics
First thing to do is check for shorts. Use a multimeter and check resistance across the power inputs and from any 5V pin to ground. Both measurements should be in the kilo Ohm range or higher. Then...

Electronics is not my specialty so perhaps this is a dumb question but here it goes. I have a 6" Prusa i3 from MakerFarm which came with their PCB heated bed, apparently using Josef Prusa's MK1 design...
View ArticleRe: Better heated bed PCB design?
If traces are equidistant then i guess its normal for the middle to heat up more than corners because its heated up from all sides, sort of speaking it doesnt get so much convection with cool air...
View ArticleRe: Better heated bed PCB design?
Yes, I've considered putting something around the sides to reduce heat loss through convection. I've also experimented with putting aluminum foil (shiny side up) on the non-contact wood platform below...
View ArticleRe: Better heated bed PCB design?
On a second thought, maybe it should be even less in the center than margins. One because the center aslo gets heated plastic deposits, and also you were measuring it static, but when bed is moving...

I have been working on a prototype, porting code and its looking good so far. I have got comms, steppers going and just working on temperature control. There's a few snafus on the board that will need...

Brilliant job bob! Will have a look soon and give some constructive feedback.

Very cool. I see what appears to be spots for six stepper drivers, but the schematic only shows five. Does it support six drivers (I hope!)?
