But the weird part is that the temperature starts dropping, and when it does, there should be an error message saying: "Heating Failed" because RAMPS is supplying current to the extruder, but the extruder is not heating. What could the reason be?
-
I have the major warping problems with PLA too. Even very small pieces warp which doesn't happen with ABS for me. My extruder temperature is 180 degrees and my bed is 70. what's causing the PLA to warp so much?
-
No i changed nothing, and i never had a board fan. Would it be a good idea to set one up? Now that i know its drawing a safe amount of current below 5 amps.
-
Ok, did that, the maximum current draw thats happening is 4.3 amps.
-
I did that, I hooked it up like that with all the loads, (none of them switched on of course). Only the main power was on, and my multimeter read that it was drawing 0.16 amps. Do i need to measure this with the loads switched on also?
-
I tried disconnecting all the loads, and found that the 0.16 amps were being drawn by the RAMPS board. Can someone please tell me if that's normal?
-
Does this mean there's a short? Or there's a problem with the fuse?
-
So i connected the red lead of the multimeter to the +12v on the power supply, and then connected the black lead of the multimeter to the main +12v power input on ramps. The current draw (with no load turned on) is 0.16 amps. I got this on my multi…
-
So basically, i switch on the main power to the RAMPS board, and then measure the current passing through the 5A fuse with nothing switched on? That means hooking each multimeter lead to each of the ends of the fuse? Sorry, again, im a complete begi…

My heater draws 2.88 amps in the beginning which slowly drops. So the inrush current is 2.88. Feels kind of high. But the fuse has other loads attached to it, like stepper motors. How do I measure the draw from those loads?
-
I'm sorry, I'm a complete beginner, could you tell me how i measure that? I'm assuming with my multimeter. Do i need to measure the resistance first, and by using V=IR, calculate the amperage based on the amount of voltage im supplying? Also, I nee…
-
The input from the power supply is 12 V 15A. Or did you mean the current drawn from the loads?
-
Hi, yes my heater voltage is 12v which matches with my power supply. I read that the more the fuse is triggered, the more susceptible it becomes to being triggered again faster. Is it the fuse? Do i need to replace it with an automative fuse? If so,…
-
I am using a RAMPS 1.4 board, would you advise attaching a resistor from the power supply to the main power input on ramps? If so, what resistor with what resistance? Or would it be wise just to unsolder and remove the fuse?
-
What is causing the polyfuse to be triggered? how can i fix it?
-
If the fuse triggered it, how can i fix it? do i need to replace the fuse? the bed heats normally though, even after the extruder stops heating. and what could be going wrong in marlin? Is there something that i can check? thanks

Is there something i could try changing in the marlin firmware that might solve the problem?
-
I'm using the latest marlin firmware, not repetier. Would that be a problem?
-
sorry forgot to mention that the led fading did not happen this time when i hit the emergency stop. I did not need to switch on and off the power to get the extruder heating again.
-
Hi, I tried another print, and the same thing seems to happen after the same amount of time. The print suddenly stops, and these weird beeping sounds start coming from the extruder. So i hit the "emergency stop" and when I heated the extruder, it wo…
-
Hi, Thanks a lot, I found that the error was being generated by the printer settings in the scripts tab. Somehow, a "M999" got registered in the start code. I erased that and everything worked fine. Thanks again:)
-
Hi, I tried printing the exact same thing, with the exact same G-code twice, and i got two different errors each time, concerning different lines. I don't know what's going on, because it's the same thing i tried to print. This is what i got when I…
-
where in the firmware do I make changes? And what do i chamge?
-
Hi, I'm not using endstops, but I've inserted the dimensions of my printer, and the park position of the X, Y, Z axis. How can I solve this?
-
Thanks a lot, the problem was , like you said, an acceleration/jerk issue. I fixed it and it's working fine. There's just one more problem, the motors only move in one direction and not the other when controlled through repetier. What could be the p…
-
Hi, this is really helpful, but If none or 2 have a connection to a single pin, what can I do to fix this? Do I need a new RAMPS? Also, what is feedrate mean. On marlin, it says "max feedrate" and in brackets "mm/sec". what do these values mean?
-
Hi, I'm sorry, but i'm completely new to this, can please you tell me in steps how to Check if the 4 output pins for motor current connect correctly to the 4 pins where you put motor in or if there is a short. Also where I edit the firmware to chang…

yes all the jumpers are on in the right places. what could be the problem?
