I'll give it a try. Thanks.by muntahunta - Prusa i3 and variants

Here are 2 pics. one of a 20mmx20mmx20mm cube... if you can call it that and my extruder bits n bobs.by muntahunta - Prusa i3 and variants
i have tightened what i think is the extruder spring tension (not entirely 100% on that) seems no matter what i do its not giving out enough filament. It worked fine when i was running the old board, what is currently running is horrible.by muntahunta - Prusa i3 and variants
I have left it overnight, came back to it this morning to start again with a clear head and now im getting a "Heater Decoupled" message on my LCD with "Error:One heater seems decoupled from thermistor - disabling all for safety!" popping up. i'm starting to believe that with the mix of broken hardware and random problems popping up every day that i'm not meant to have a 3d printer at all.by muntahunta - Prusa i3 and variants
Managed to sort the height out, apparently repetier was overriding the firmware. I now have an extruder problem. the extruder is an MK8, it doesnt "grip" the filament. when i push through with my hand, the filament comes through fine, but no matter how many steps i put in, it doesnt seem to be pushing filament throughby muntahunta - Prusa i3 and variants
as a quick note. I printed a 200x200x200 mm cube. It was not printed in the middle of my bed. the dimentions of the finished cube are 163mm x axis 163mm y axis 10mm z axis yes, that is right 10mm. I have 2560 steps per mm on my Z axis.by muntahunta - Prusa i3 and variants
Has anyone got the firmware that comes with the Hesine Prusa I3? I know the Hesine uses a Melzi board, but it is pre-configured for use with the hardware of the 3D printer. I have changed over to a RAMPS1.4/Mega setup and I am having a nightmare trying to setup the firmware. the "Print area" starts from 0mm, however I have 34mm along the x axis and 12mm along the y axis from the endstops to theby muntahunta - Prusa i3 and variants
I have finally got my 3d printer working (I bought ANOTHER board) now, I have used the repetier firmware and its configuration tool on their website to put in everything for a simple startup, my problem is now that within repetier host, when i try to move my X axis further than 200mm (I have 50mm from the x endstop to the print bed) it wont move it any further. (it isnt calibrated yet either so tby muntahunta - Prusa i3 and variants
The parts on my printer are too big to fit into the gap of the optical endstopby muntahunta - Prusa i3 and variants
Ok, as a lot of you may know by now, I have had extremely bad luck starting my 3d printer project. I recieved a melzi 2.0 which had zero connection through USB (assuming the chip is broken or it hasnt been flashed with the bootloader. I tried many suggestions from installing drivers manually to downloading different interfaces to try and connect. The computer still doesnt even recognise new hardwby muntahunta - Prusa i3 and variants
Well, The power supply was used to power my other board and it worked fine (apart from 0 USB connection) running 20 hours in a day. The LED light is coming on and ill check tommorow if it still runs the other board (im expecting a USB ISP programmer tommorow for my old board to try and flash the bootloader). To my knowledge the power supply is still working. I will try and get a multimeter asap.by muntahunta - Prusa i3 and variants
The power supply is fine and working but I think you may have possibly solved the problem... I checked the power supply and its a 12v 15A.... Obviously it needs 16A, but surely this wouldnt give much problem if there is literally NOTHING plugged in other than the RAMPS?by muntahunta - Prusa i3 and variants
i dont own a multimeter, but since i plan on expanding my amount of printers to 5+ eventually, it may be a good tool to have. as for a 12v lightbulb.... im not a lightbulb expert in any way, but im from the UK and im sure bulbs here are rated in watts. why, do you have an idea? (idea, lightbulb, ding.... ill leave now)by muntahunta - Prusa i3 and variants
I tried this before posting here. He says that to test using the lcd (giving a white screen) that the USB power isn't enough, which is the reason i tried to connect the power, nothing happens when connecting the power. with just USB I get the same white screen he gets, but that could be due to lack of power from USB in comparison to the PSU. So I cant use his testing method unless I have the powby muntahunta - Prusa i3 and variants
just read all of that and I have checked the "chip" next to the power input on the mega and it is indeed fried... however I am certain that I have my wiring correct. and also, wouldnt the ramps still work by itself? What do i need? a new ramps? a new mega? both? a wiring guide that isnt going to blow up yet another part?by muntahunta - Prusa i3 and variants
wouldnt the LCD not work if the RAMPS was broken? Also, I know I wired things correctly last time as I triple checked the wiring against the wiki, so I'd prefer not to fry another one if I could find out what I did wrong. is it definatly 100% broken?by muntahunta - Prusa i3 and variants
I've tried to power the RAMPS 1.4 board with the power supply with no arduino attached and nothing. Any tips on what to do?by muntahunta - Prusa i3 and variants
Ok guys, quick update. I've plugged the mega into the USB and it is powering on. I then plugged the ramps into it, plugged in the USB and got a flashing LED with + next to it, which im assuming is good. I then plugged the LCD screen in just powered by USB and got a bright screen with nothing on. I read online that the LCD needs more power than the USB can handle so I plugged in ONLY the power sby muntahunta - Prusa i3 and variants
im so annoyed with myself im not sure it even works anymoreby muntahunta - Prusa i3 and variants
Cold solder? ill google hahaby muntahunta - Prusa i3 and variants
How would I figure this out? im new to all this and smoke is definatly new to me.by muntahunta - Prusa i3 and variants
I looked for the size on the internet and forum and the size they said was 1mm... do you think ive blown it?by muntahunta - Prusa i3 and variants
and now nothing. the power supply still has a green light but im getting nothing from the board or screen or anything,by muntahunta - Prusa i3 and variants
I've just put a ramps 1.4 with mega to replace my melzi. Plugged in everything according to the wiki. Turned it on and smoke came straight away. I immediately knocked off the power. I have no idea where the smoke came from and it was working great with my melzi. I'm now left without a printer (really don't wanna take it all apart again.) Pics of my stuff below. Only thing new is the orange cableby muntahunta - Prusa i3 and variants
I have purchased 3 optical endstops to replace my current mechanical endstops, but I have absolutely no idea how or where to mount said endstops. I have looked online for a guide or two, but I have turned up nothing. not even a picture of where to mount them. Any help would be appreciatedby muntahunta - Prusa i3 and variants
thanks its more the type of wire tbh. im not sure on what kind I need (im not an electronics type of bloke yet )by muntahunta - Printing
its a melzi 2. the "customer support" if you can call it that have said that they think the chip is faulty and are sending a new one. ive got an arduino/ramps combo here, just waiting for some dumont connectors and to figure out how which wire i need to connect my power supply (its not a computer power supply) as it requires 4 inputs instead of the two that melzi has. then im gonna make a 2nd pcby muntahunta - Printing
I have no idea, it has not worked since I got it a few weeks ago. The printer can be powered by USB, but the PC doesnt even recognise that any hardware has been put in. I have tried manual driver installs, etc. I have no idea how to reflash a bootloader or anything, im new to 3d printers haha. Im using SD card for transfering files atm.by muntahunta - Printing
I have PLENTY haha. my printer currently wont connect to the PC so im unable to calibrate it. lots of broken bits while i wait for my new parts. Ill give it a go. thanks for the advice.by muntahunta - Printing
