Re: 24V with Ramps 1.4 questions - 12 years ago

You could do what I have done recently which is buy a dc-dc booster rated at 600w for £16. I run an atx psu which has plenty of power but runs at about 11.5v which means my pcb bed takes a while to heat and has a max of about 90c. I have the booster set to about 14.5v which is lower than the max rating of all my ramps components. The increase of 3v increases my beds power from 100w to 160w which

Anyone used a Thermal Conductive Silicone Pad for PCB Bed? - 12 years ago

Has anyone used a thermal conductive pad on there pcb heat bed like http://www.ebay.co.uk/itm/180930963328 between the pcb and glass or aluminium surface? If not can any one see a problem with something like this? Im thinking that better thermal contact will improve warm up times.

Re: Smoke/steam coming from new J-head hot end - 12 years ago

If it is a new hotend is it a new thermistor too? If so have you selected the correct one in your firmware? You could be burning your filament

Re: I think that my j-head is not working??? - 12 years ago

try increasing the temperature a bit. Are you able to manually push it through the tube?

what type of plastic are you trying to print? and what temperature are you using??

Re: ATX PSU with two 12V rails - 12 years ago

Its not always the case though. I have a relatively cheap atx supply for mine. I use the motherboard connector and the P4 connector as the atx spec says they should be on different rails. They both have slightly different voltages and if one is loaded the voltage drops but the other says the same. But you are correct most are connected together. So your best bet is just give it a try. It will

Re: Ramps1.4 power woes - 12 years ago

It all looks ok. Do you have another usb cable and pc you can test it on. if it still doesnt work even with the 12v not connected i would say you have a faulty arduino.

Re: Motors move back and forth when printer is powered - 12 years ago

that sounds like some sort of test firmware to make sure the motors work and everything is wired correctly. I would suggest trying to upload the firmware.

Re: Is it possible to repair a stepper motor that has internal stressed wires? - 12 years ago

It should be possible to open and fix. You should be able to either resolder the damaged wire. If pad on the pcb is damaged you will need to trace is to where it connects to the wire from the coil and bridge it with a new section of wire.

Re: What would be a good upgrade for my hot end? - 12 years ago

try insulating the heater block. I wrapped my jhead in about 20 layers of ptfe plumbers tape, then a bit of kapton to hold it together. much more consistant temperature now. Might work for you too.

Re: Replacement for the screw terminals - 12 years ago

atx are molex mini fit jr any reason why you dont want screw terminals? how about crimp something onto the end of your cable then insert that into the screw terminal? Thats what I do so i dont wear out the cable and less chance of breaking.
