So I just finished building my prusa and I printed some test cubes and endstop holders and it was all fine but when I started printing a larger file I left and when I returnet it was stopped and only leaking filament, then I tried homing all axis but there was a message saying it was in the middle of a print even though it was all still. What could be causing this problem?by matheustorres - Printing
I did kind of a bad soldering job but I tested the continuity between the end of the wire and the underside of the solder and it was OK for the 2 wires, but the continuity between 1 and 2/3 by touching the metal plates did not workby matheustorres - RAMPS Electronics
Hello, so I already tested my heated bed directly on the power supply and it was OK, I tested with pronterface and it was OK, now for some reason it is not heating up again, I checked the continuity and it has none, is there anyway to ressurect it? What could have caused it?by matheustorres - RAMPS Electronics
So when I turn on the printer, the Z axis is for example at position 5, if I say to move 6 up, it moves, if I say to move down 6 it moves down, but I cant go down past position 5, if I manually turn the cart to position 3, it wont go down position 3, I am pretty sure it is a config setting and I don't know which one it is. Another problem is the first time I home X or Y, Z axis goes up with weirby matheustorres - Reprappers
Update: It was really a typo error, for some reason I can't turn the Z axis down, only up, why is that? How am I going to position my endstop on Z axis without the program letting me move it down?by matheustorres - Mechanics
Yes I was using pronterface, actually this homing problem is caused not only when I home X, but when I first open the program, the first time I press home, either X or Y, it lifts the Z, and after that the home works fine. Pronterface has a macro to do that? Which software do you recommend?by matheustorres - Mechanics
So let me explain what is happening: Right on the start of the video I press home X and for some reason the Z axis turned and it seems like it got stuck, then X goes home normally; Next problem is the Y axis, I gave the command to move 10mm and it went like 100mm and when I press 1mm, it moves probably like 10mm, and, with the 1mm command, the Y bed moves catching a lot with a really jerky motioby matheustorres - Mechanics
Turns out that all the connections were OK, what was shorting out is that I directly put the endstop with a ziptie and 2 endstop connections were in contact with the metal rod causing a short....by matheustorres - RAMPS Electronics
So if I buy a new endstop and plug the arduino permanently to my PC, it should work all fine?by matheustorres - RAMPS Electronics
Hello, so now that I got home I started to figure out what combinations were causing problem and it turns out that only when endstop X is connected that the arduino does not get recognized by usb , and it only gets recognized when I trigger the X endstop, so here are my questions: Should I cut off the + cable from all endstops? Should I buy a new RAMPS? If I buy a new endstop , can I still use tby matheustorres - RAMPS Electronics

By the way, can this short affect the RAMPS or is it safe?by matheustorres - RAMPS Electronics
When I get home I will post a picture of my wiring. VDX, should I test for short between the S and + and S and - from the endstops?by matheustorres - RAMPS Electronics
Hello , like I said before, my first arduino got fried probably because of the endstop, now the second time I plugged all the connections correctly and before turning the power supply on I noticed that my arduino was not getting recognized by my PC, it only got connected when I pressed down the endstop, and if I take of the endstop connection, the arduino connects normaly and when I plugged the pby matheustorres - RAMPS Electronics
Should I just screw in with the terminal blocks? Won't it cause any problem like shorting out?by matheustorres - RAMPS Electronics
QuoteDust There are normally two fans. one that is for cooling the the fins on the hotend. This is normally always on and plugged into two pins 12v supply (see image) Secondly most machines have a plastic cooling fan, to solidify the plastic after it has been extruded. this is controlled and needs to be plugged into D9 Hello Dust, but how should I connect to this two holes? Should I solderby matheustorres - RAMPS Electronics
I bought a MK8 extruder and the extruder fan has a connector just like the image attached, and I was wondering, should it be plugged somewhere? Or should I just cut out the connection and screw it on the D9 output, or should I screw in the ramps terminal block input, if so, on the 5A or 11A, or should it go directly in the power supply?by matheustorres - RAMPS Electronics
Mine is the standard mechanic one, if I cut down the red wire it should be no problem then?by matheustorres - RAMPS Electronics
Hello, I read in some places that you should never plug the endstop wires on the VCC, but my endstop has 3 wires, should I cut off the + wire or am I not going to have any problems with that? I already fried one arduino and I think it was because of thatby matheustorres - RAMPS Electronics
But as far as I know, WD40 would just lubricate the screw and it would turn more easely, but my problem is that it is too sensibleby matheustorres - RAMPS Electronics
When I started tuning the drv8825, I was going for about 0.8V, but one of the drivers there was something wrong with the potentiometer, because when I had a reading of 0.3V and turned half a milimiter it went up to 1.5V (really) and after a very long time I got to about 0.82V, my worries is, when I start printing, because of the vibrations the screw is probably going to make the potentiometer chaby matheustorres - RAMPS Electronics
By the way, the arduino got fried, today I bought a new one and it is all working fine. Now that I think about it, it started smoking when the endstop got triggered so probably it was the problem that Dust suggested, about the wiring, I probably plugged in the wrong way, insted of S - +, I did + - S, if you want I can send the picture but only tomorrow, let me knowby matheustorres - RAMPS Electronics
My endstop has 3 wires, + - and signal, I heard that there are some problems when connecting to the +, should I remove the + wire and will it work fine? By the way it was not connected to the USB, it was plugged but not plugged in to the PC, all of the power was coming only from the 5A 12V input. About the vref, was I measuring it wrong?by matheustorres - RAMPS Electronics
Hello, yesterday I got my stepper motors and I decided to test them, so I wired the ramps like this: I put all the DRV8825 on the right place, put only one stepper motor on Y axis, one endstop for Ymin, and the LCD connected, on the terminal blocks I had only the 12V 5A input wired, after messing around with the motor movement and pressed auto home, it went to the endstop as expected and about 5by matheustorres - RAMPS Electronics
