Ok, thanks. I sent a question to GITHUB\MARLIN in order to make some change,on this. Thank you.by Amachete - RAMPS Electronics
Hello I am trying to make these drivers to work, but I have my PSU by default, I have just arise an Issue in github\MARLIN so that the M122 command does not work if the psu is off (I have the protectors on so no problem with EM issues) I have 2 psu on my printer, one small that turns on with the printer and feeds the RAMPS and arduino ,and other 12V PSU which turns on when MARLIN sends M80 GCOby Amachete - RAMPS Electronics
Yes The storage box might go up the printer..but this is not main thing... What I am trying to do is to avoid the main extruder has to pull the filament from the ROLL. I want to avoid any kind of strain in the filament before being pushed.... I think that is the main problem of misstepping in extrusors.... So pulling filament with other extrusor would avoid this problem...I guess.. Yes i knby Amachete - Developers
That idea sounds great! Do you know any design similar? I have been looking for something similar in thingiverse, but without any luck maybe I am not using the right words... Do you know any design? Thank you!!!by Amachete - Developers
Thank you for your answer. The thing is I am using this box for storing my filament rolls Filament Storage Solution (IKEA SAMLA) which is under my desk. My printer is a Prusa i3 Steel with some add-ons to guide the filament up to the extruder, but from time to time I am having problems....that ´s why I wanted something to pull and push the filament to the extruder....I think that idea would solby Amachete - Developers
Hello I would like to ask if there has been any kind of development about "pushing filament to a direct extruder/wade" I do not want to use a Bowden system, although I know that It works great, I prefer wade´s system. What about mixing both systems? I want to use the direct drive system, or wade´s...with a motor on the X-Axis, but I would like to use the second extruder motor, which I do notby Amachete - Developers
Hello I am trying to control a fan with arduino as It is explained in this blog: But I want to make it different,... I want the fan works by default, just in case the arduino fails, or something happens.... The circuit I am trying is the following, modelled with LTSPICE.. .. I am using a pulsed power source as Arduino´s PWM. The problem is that pwm power source gives me 270 mA back to Aby Amachete - Experimental and Hobby
Thank you for your detailed answer. In the end I am using the latest RELEASE CANDIDATE OF RAMPS, V2,..which has a new feature, you can have a separate pin for you autolevel device...This feature is what I was looking for... // Support for a dedicated Z probe endstop separate from the Z min endstop. // If you would like to use both a Z probe and a Z min endstop together, // uncomment #deby Amachete - General
Hello I want to use my old and very reliable makerbot 1.2 endstop with three wires with my brand new capacitive sensor(I do not trust that It is so reliable) I am using a circuit with an optoacopler like this one Circuit I do not know what I am doing wrong, but It does not work....so the question is: Is it possible to have both endstop and capacitive sensor working ant the same time? what doby Amachete - General
Hello Is it possible to bind the capacitive sensor to another pin that the pin used for Z-Min Endstop. In my Set-up I need the sensor works regardless of the Z-Min Endstop..... Where should I look at in the MARLIN configuration files? Thank you all.by Amachete - General
Hello As a 5V psu, I used a old phone charger, which supplys 5v 500mA. I did not removed the d1 diode. As soon as I can I will update the Reprap wiki with some graphics...currently I am trying to create a pcb Fritzing RAMPS, that It does not exist yet. I will pst when I finish it.by Amachete - RAMPS Electronics
Hello Enif. I just want to tell you that the Diode Schotty works as a charm, no problems with the LCD. Thank you very much for your help.by Amachete - RAMPS Electronics
It worked!!! I just put the PS_ON, and V5 on the Vcc(without Diode) and the ground wire on one pin of the servos areas(USB connected) and IT WORKED!!! I was able to send comands M80 and M81 through Pronterface. But It is neccesary to change in configuration.h the type of PSU, from ATX to X-BOX, because the logic Is not right as you can see: // Power Signal Control Definitions // By defaultby Amachete - RAMPS Electronics
Yes, there is not a black wire(ground) attached to RAMPS as they are part of other circuit apart of the main PSU(12V), I guess it is necessary.... I thought of it but as this wire does not appear on any of pictures or graphics, I have looked at,...I did not put it in. the main thing is I do not know where to plug it, and close the circuit!!! But in my opinion, this V5(Stand by) is not necessby Amachete - RAMPS Electronics
I hope you can see my setup. If you need more picture, let me know. I unplugged other wires and Ispread the mess of wires in order to see something, I hope it helps... thank youby Amachete - RAMPS Electronics
Yes It Is. There is a jumper on. The power led brights quite well, But the other is always on, a bit dim, not full power, Even though I send M80 and M81, The light is still on. I made a test with the V5sb, and the PS_ON cable "crossing" them, and the led brighted as hell, and the main PSU switched on.... I do not know If this helps, If you need any other thing to do...I think I have alreadyby Amachete - RAMPS Electronics
Ok thanks. Your are right, that is wrong on that diagram, but I am connecting right that bit, 5V Power supply, I connect to Vcc to 5V and Ground to Ground. The relay power led, switches on., If I put them wrong It should not light up, doesn´t It? The problem comes from the IN pin, I guess... Other ideas?by Amachete - RAMPS Electronics
Hello I am new on this forum, and I would appreciate some help with this mod I would like to put in my Printer. I have read everything I have been able to find on internet but I can not get it work. My problem is the following: I want to use relay to switch on/off my PSU as in this topic explains :http://reprap.org/wiki/Power_Supply#Controlling_the_PSU I bought the following relay:http://eby Amachete - RAMPS Electronics
