Re: My little ARM board
well, first thoughts - it's a good idea, I'm looking at an NXP ARM device for a new board design, but I'll throw my criticisms in as well: Your cap's near the pins will affect your sample times on the...

put a faraday cage around your electronics, ground the shield of the USB on the cage - that way if you do shock/short circuit, it won't interrupt anything.

Hey folks, So after a major disaster with my old RAMPS board, I've migrated to a new RUMBA board and a new PSU. Although I've made good progress, I've some major problems with the motors and endstops....

Hmm, interesting project. I'm inspired to play with the TMC2660 drivers now. However, I was looking around your site and couldn't find what motion controller IC is used. It's labeled as 4361 on the...

A 74HC07 is not a good way to make a high speed level changer as you get a slow rising edge, depending on the pull up resistor. A 74HCT08 or similar should be used to go from 3.3V to 5V logic. It will...

So I am getting ready to build my large printer and I want to use 24 volts for large bed , etc. My question is how much amperage can a Rambo board accept and send out ??? Also, I want to use Nema 23...

I got it ,maybe is the fireware can not handle the signal voltage well , when I try to make a SD CARD work with repetier ,I found that the repetier sdfat.h can not make SPI work ,but arduino original...

According to the wiki [reprap.org] the rambo has 3 power supplies with the following rating: Heated Bed, 15A 12-24V (version earlier than 1.1 limted to 14A 16V due to fuse rating, see...

I really need to know how much each stepper can handle in Amps so I can make sure I can get the correct Nema motor. Thanks Steven
View ArticleRe: reprap.me stepsticks and Gen7 ?
QuoteTraumflug That's true, Gen7 hardwires MS1 to high to save a resistor and a jumper. Sorry for Hijacking this old Thread. But does that basically mean, that i have to add a Jumper for MS1 and a...

I am thinking about 3 inputs for incremental encoders (3 axis supporting closed loop control) Reprap is by all means 4 axes, where the extruder is the 4th dimension - and the most important one. So i...

Yes on second thought i think could use it like 3 closed loop for x, y and e, while leaving z open loop, this way could stick with 3 closed loops in sort of a 3.5D movement, where z only counts for...
