Hola Pely, Soy de Buenos Aires, y tambien estoy armando uno de estor bichos. Creo que estoy a un 50% de terminarla, donde el 100% sería tener algo impreso. Estoy armando una RepStrap similar a la Wolfstrap, con arduino mega y RAMPS 1.25. Los motores paso a paso fueron obtenidos de impresoras HP viejas. Actualmente estoy luchando un poco con la electrónica (se me quemaron 3 Stepsticks), y termby epoxi - RepRap en Español
Hola Gente! Aqui Lucas, desde Argentina. Les comento que mi idea es construir un RepStrap primero, para luego contruir una RepRap (hija). Por el momento tengo: * Arduino Mega 2560 (chino) * RAMPS v1.25 (hecha en casa) * Stepsticks (comprados en eBay) * OptoEndStops (hechos en casa) * Motores paso a paso sacados de impresoras HP viejas. En cuanto a la estructura, es muy parecida a la Wolby epoxi - RepRap en Español
JKomp316, thanks for your reply! Hmmm... so the A4984 are not an option? Did someone experienced the same with these Stepsticks? How about this one from tv7957ht (eBay) Thanks!!! LCby epoxi - Reprappers
Eugene, The stepper moves even with the trimpot at its minimum. And during all work, the StepStick were not hot at all. The steppers are ones that I took from an old HP Deskjet printer --> 7.5Deg per step 13ohm per coil 4 coils (6 wires). I red somere that the StepStick needs filtering capacitors at input VCC and V-MOT. Those capacitors are not in RAMPS 1.2 or 1.4, but they are in Gen7.by epoxi - Reprappers
Hi ECSuyu, At first use the trimport were in te middle. In that position, the stepper motors got warm when idle. You could touche them with your fingers without any problem. The Stepsticke had the dissipation installed. Now when moving the trimpot, to which side is the Max or Min ?? Thanks for your help!! LCby epoxi - Reprappers
Hello RepRappers! Well, I'm writing this because I blew up 2 Stepsticks in a a row, and 1 more the next day... And I don't understand why that happened yet. I made mayself the RAMPS 1.25 board (the one with the 1K R for the LED). I attached some photos of it. Note that the pictures were taken before the Diode 1N4004 was desoldered, and the MFR500 fuse was installed. I'll tell my story. Afteby epoxi - Controllers
