QuoteTshawkins You should not have any problems attaching the hobbycomponents drivers, you just need to locate the pins on the pololu socket on the ramps board, that has the 4 signals you need, a simple header with the wires soldered onto it would suffice. You may possibly have some issues with pulse width on the step and dir pulses, but i belive those are configurable on Marlin, as the there waby _dreamer - Developers
Hello, I have a conveyor belt system set up as my y-axis. What I want to do is, create a generic g-code to position objects in an exact potion on the conveyor belt before executing the main sequence of g-codes (print operation). I use the signal wire of a photoelectric switch to input +5V to pin D59 on AUX2 of RAMPS. I believe that pin is technically the A5 pin on Arduino. when trying to pauseby _dreamer - Developers
Quoteo_lampe Are you aware, these are NEMA23 steppers with a different footprint than the common reprappers NEMA17? You could also use drv8825 drivers, which fit on the stepstick port and deliver 2.5A max with cooling. Your steppers would loose only a small amount of torque then. They also have 1/32 step capability, reducing the noise of the NEMA23 alot. -Olaf Yes, I'm aware that they are Nema2by _dreamer - Developers
this is the motor: . Quotethe_digital_dentist You've got it completely upside down. Though it doesn't seem to be done very often with regard to 3D printers, the torque needed to the job is calculated first, then the motor is selected to deliver that torque, then the electronics are matched to the motor. 3V (and less) steppers motors are quite normal and common even in 3D printing, and RAMPS wby _dreamer - Developers
I'm developing a conformal coating unit based on RepRap electronics and software. I already an extra RAMPS 1.4 and my host and firmware are heavily modified version of Printrun/Pronterface and Marlin, I'd like to stick with RAMPS 1.4. The stepper motors I have for my X,Z axes are rated 2.8A/phase (3VDC), and Pololu A4988 are clearly inadequate. Will RAMPS be able to handle a driver such as this:by _dreamer - Developers
