Hello akhlut , this will be the first thing, when I come back from work. Thanks, seeya later.by deepbreath - General
"Are you sure you have the endstops on the correct pins?" - Yes, there are two possible situations - one is correct, the other one - incorrect. I already checked the forum for solutions. Another guy had similar problems, but he had really connected the endstops wrong. However, I connected them correctly, otherwise my RAMPS wouldn't have powered up. I think I have mechanical endstops. How can Iby deepbreath - General
Thank you, akhlut. "Issue 1 - Do you have the machine hooked up like the image below? " Yes, exactly. "What board have you defined in firmware?" #define MOTHERBOARD 34 // 34 = RAMPS 1.3 (Power outputs: Extruder0, Extruder1, Bed) I haven't found a constant for RAMPS 1.4 "Issue2 - If you close one of the switches does the state change in pronterface?" As I've reported, the status of my endstopby deepbreath - General
Hi guys, I ordered a reprap kit from RepRapBCN a few months ago. To everyone (not enough experienced) - do not buy your kit from them: you will not receive any good documentation nor support to build it. I am a software developer, so assembling the reprap with the info from internet only was a big challenge for me. I assembled it and now I'm trying to test it with pronterface. I'm able to conneby deepbreath - General

Hello, thanks for the reply, but that's clear, I've installed the arduino board without any problems. The problems began when I attached the RAMPS to it. I spoke about Windows' "Add New Hardware" dialog before because that's the easiest way to determine if arduino is recognized by Windows as a device without installing any drivers. That's exactly what I did before: connected arduino, windows opeby deepbreath - RAMPS Electronics
Thank you for the reply The host PC is a desktop machine. However I've confirmed the problem with two desktop machines and a laptop - it's the same - with more than one motor driver carrier attached the arduino's ON LED goes off. I've tried powering up arduino directly via the jack using an external power supply (12 V). The ON LED stays on with more than one driver carrier attached, but the conneby deepbreath - RAMPS Electronics
Are there any instructions about powering arduino from another power source (not from the USB cable). I thought it's being powered via the RAMPS power connection, but it seems I am wrong because with 2 motor drivers attached to the RAMPS my arduino's ON LED goes off. Am I the only one having such probem? I've searched a lot for such an issue and I am surprised I haven't found anything like it.by deepbreath - RAMPS Electronics
3th update: According to arduino.cc/en/Main/ArduinoBoardMega/ when using an extarnal power source the input voltage can be measured using VIN and GND. When I measure the voltage when my RAMPS is powered up it's 4.7 V meaning the arduino is powered up from the USB cable. I can not understand why it stops (the ON led lights for a few seconds only) assuming the stepper motors should be powered up byby deepbreath - RAMPS Electronics
Thank you for the response. I will try connecting the arduino separately. Meanwhile I continued playing with the board. During my last attempt to determine what's wrong two of the motor driver carriers stopped working. So I decided to continue testing with the two of them, which seem to be working (while attached to the RAMPS the arduino's ON led indicated the board is on, and the RAMPS LED01 wasby deepbreath - RAMPS Electronics
Hello, first of all I want to apologize if case my problem has been already discussed in another thread of the forum, but I've checked almost all of the topics and haven't found anything close to my case. So, I've ordered a reprap, assembled it, but I am stuck at the electronics. I plugged the usb cable to the PC but my windows didn't recognize the arduino (it didn't open the Add New Hardware popby deepbreath - RAMPS Electronics
