Re: Replicape, a BeagleBone 3D-printer cape, is ready for pre-order
The CNC-software on the BBB is not LinuxCNC. As far as I know LinuxCNC uses a real-time kernel and a Periodic Interval Timer for stepping. I am instead using a custom Python script called Redeem that...

View ArticleRe: RAMPS for Due!
I am interested in powering servos from the RAMPS-FD, but I did not take the 3.3V logic level into accout. So I am wondering if it is a good idea to run them directly from the RAMPS-FD. I am looking...

Thanks! It's been over a year in development, so it's good to get it out to the masses :) But it's also good to see other CNC solutions based on BBB. In my opinion that board has a lot of potential as...

On servos, I did some research before and it appears most servos will accept a PWM voltage of 3-5V, so that should be ok, although I didn't find an official standard, it seems that 3.3V compatibility...

View ArticleWill repetier, marlin, teacup, or any other firmware work for me?!!!!
I have an arduino and ramps 1.4 setup and have tried just about every different firmware to try to solve my problem. That is to drive my motors consistently. I have some 7.5 deg. steppers from an old...
View ArticleRe: Will repetier, marlin, teacup, or any other firmware work for me?!!!!
7.5 Deg stepper motors should work fine ASSUMING they're 4 wire stepper motors, and not 5 wire. I don't know (off the top of my head) any RepRap electronics that will drive 5 wire stepper motors. Note...

Thanks Brian! That looks like it should do the trick. I forgot to mention I'm in the UK so does anybody know if I can get this anywhere in the UK or Europe? Otherwise I'll get that one ordered Sam

@bobc: Ok, then I am going to try option 2 when it comes to testing servos. @Gordie: I heard once that using a dual motor setup for one axis and microstepping is not a good idea, but I am not sure if...
View ArticleRe: Will repetier, marlin, teacup, or any other firmware work for me?!!!!
Thanks for the reply. They are indeed 4 wire bipolar motors but whenever I calibrate the number of steps per unit in the firmware and set the max feedrate the motors still jitter and will maybe turn 1...

I have made a prototype, but my TB6560 seems to be running hot without moving a stepper motor. What can it be? All other functions are working properly with Repetier, but these TB6560 are a lot more...

Quotebobc One issue that I nearly mentioned but didn't was the question of opto-couplers. It seems on the skynet boards, they run off 5V which is provided externally. The optos would sink about 12mA...

Maybe something like this: [pages.ebay.com]. You still need the tubing on the leads though. A search for "reprap thermistor" gives you a few results.

I've been working with the Ramps 1.4 test code and by changing the delay after the digitalwrite(xyz step pins) I am able to get the motors to run. Am I right in saying that the pulse rate is the...
