Solved the issue on my RepRap was a three part problem: 1)My power supply did not have enough power....was using a 400W power supply....had to upgrade to a 500W 2) I was using 3V motors instead of 12V motors this caused major issues....including an exploding driver...due to overcurrent 3) On examining my endstops more closely I realized I had attached the leads to the normally open and the norby pastlifeuknow - RAMPS Electronics
Quotecncjoe (use full power here:#define MAX_BED_POWER 256 // limits duty cycle to bed; 256=full current-was 128 3-17-2013 I'll give that a try. Quotecncjoe One more thing. I've noticed that I don't get accurate results when I change the pot while the motor is trying to move. I've had best results clicking 10mm, waiting for it to stop, changing the pot a tiny bit up or down, and click 10mm aby pastlifeuknow - RAMPS Electronics
I'm using the high current ones. No matter the trim pot I'm getting the hum. It used to work but connection issue caused by what I think was firmware BAUD rate issue froze the connection. Also all the motors suggested by reprap.org and most of the forums that I've read are 5v or greater and about 5hom these motors are neither. They are 3ohm and 3v.by pastlifeuknow - RAMPS Electronics
Ok so the motor is 3v. the coolmax V-500 power supply is giving it 12v 17amp. if I used the 5v 22amp or the 5v 2.5amp would it work? could this possibly be my problem?by pastlifeuknow - RAMPS Electronics

QuoteAndrew Smith > -No heat bed installed nor is the temperature > sensor or heater is installed. This is a problem - Marlin shuts down if it doesn't get a plausible reading from the extruder temp sensor. There should be an error message about that in the right hand of pronterface? I didn't know that however I did disable the heat temperature with these lines of code found in marlinby pastlifeuknow - RAMPS Electronics
My advice from my experience so far. Go to reprap.org or youtube and follow the spec to the letter There are part lists find everything exactly as they say. Once you get one working then you can mess with it. Buy pre-made electronics if you aren't comfortable soldering (though make sure you check these forums that the place your ordering from is trust worthy) Most important thing to be aware ofby pastlifeuknow - General Mendel Topics
I personally am new to Reprap but have had the assistance of a classmate who has built both a Prusa and got a broken Cup Cake operational. He's also been involved in making I believe a huxley and one other (can't remember which ones was just chatting with him as he printed parts for them. He later confirmed they were operational). I've looked every where to solve my issues. I had a 230W power sby pastlifeuknow - General Mendel Topics
I forgot to mention I'm using Pronterface. When I pressed the endstop (clicked them) a message showed on the Proterface display saying they were clicked.by pastlifeuknow - RAMPS Electronics
So I've looked every where to solve my issues. I had a 230W power supply. My motors would turn on move for a second then turn off and I'd lose connection. Thought it was power supply because minimal requirements according to forum and reprap.org is 300W power supply. Realized after installing 500W power supply (coolmax V-500) that I had forgotten to Change BAUD rate in Firmware. Now with new powby pastlifeuknow - RAMPS Electronics
Check out OHMBASE.org their the local Hackerspace I believe they have one. They are also on facebook and on the Hackerspace wikipageby pastlifeuknow - Canada, Thunder Bay RUG
I've got the new DRV8825 (model b) with my A4988 I would get 12V in reference to ground on my RAMPs 1.4 but with the DRV8825 I don't any suggestions? I tried the Tying the Fault to the Sleep.by pastlifeuknow - For Sale
