Just finished printing this power supply cover w/ switch slot (http://www.thingiverse.com/thing:40377) thought you guys might want to print one and wire it up if you want a switch.by coldfront - Prusa i3 and variants
Quoterich1812 Quotecoldfront Quoterich1812 DUH! I just realized that the switch was pre-set to 220V not 110V, How silly of me! Yeah glad you figured out the PSU problem, but did it fix the heating problem?? Seems like it does, right now I am running a stress test, I have the hot bed and the extruder running for almost 3 hours now and monitoring it, So far it never drops below the target temperby coldfront - Prusa i3 and variants

Quoterich1812 Wow, coldfront, you are an early bird like me ! Haha I wish more like really bad insomnia daily I don't get that much sleep often, but is this how you have your board setup??? Also what made you pick an ATX PSU rather than use the one supplied by Folgers?by coldfront - Prusa i3 and variants
Quoterich1812 Hi coldfront, Are you saying that the thermostat is already built in the bed? Because of the lack of instruction for this kit, I read it somewhere on the net, I think it was Instructable.com, it says that I need to connected a 103 NTC in the center of the bed, so I did. Like Jamus, I also thought the thermostat was missing from the kit. Perhaps that's why I have the shut down issuby coldfront - Prusa i3 and variants
QuoteNukedWorker Quotekonto89 At present, I used some settings posted by another user quite some time ago (sorry, can't remember ID): X: 0.33V Y: 0.55V Z: 0.35V Extruder: 0.35V This also begs the question, as there is no visible movement with the cold end, how can you perfect the extruder vref value having nothing to go on? I have also wondered about what the correct vref should be placed at...by coldfront - Prusa i3 and variants
Yeah I think trying a bigger psu might work out better I think the one folger sends it 30amps I believe I will have to check. Quoterich1812 AAAAAAAAAAH! It's baaaaaaaack! This is driving me crazy! After working for like 15 minutes, the problem comes back. I isolated the problem by connect the 12V negative to Pin2 alone, then pin3 alone, in both cases it works fine, so it confirmed that the bby coldfront - Prusa i3 and variants
QuoteJamus Hey everyone, getting close with my folger kit and have a quick, possibly repeat, question. The thermistor for the heat bed, was there supposed to be one with the kit? Other than some 3m hardware it's the only thing I can find missing in my kit. The thermostat is on the heatbed already you just have to solder two wires to the small pads on the board doesn't matter which way it goes.by coldfront - Prusa i3 and variants
QuoteBayAreaRepRap Anyone use any LM8uu linear bearing alternatives? The ones included lose balls like crazy and are the crunchiest bearings I've ever seen. I'm thinking of getting some 8mm bronze bushings. I haven't had any issues with grinding sound or lose of balls but sorry i dont know of an alternative.by coldfront - Prusa i3 and variants
Quotecdru That sensor is a NC NPN sensor. It works by always grounding the signal wire until it's tripped, in which case the circuit opens and the signal wire should be pulled high by a pull up resistor. It should be wired and configured just like a NC mechanical switch with the addition of the extra wire to power the sensor, so you should enable the pull up resistor in the config file and ditchby coldfront - Controllers
Hmm clicking sound I don't know anything about clicking, is it more of a clicking or is it a beeping sound?? but it seems that 1-2 seconds after starting the heat it happens right? i mean it can't even get to 60c that fast, must be another problem. my settings for the HEATER_0 are as follows. // When temperature exceeds max temp, your heater will be switched off. // This feature exists to protby coldfront - Prusa i3 and variants
Quoterich1812 Hi coldfront, thanks for your reply. You were right, I did wire the hot bed wrong, after re-wired now it works fine. as for the filament, this is the one I bought on eBay, 2meters PTFE Teflon Tube For 1.75mm Filament for 3D Printer RepRap Rostock. It says 1.75mm but it's way to big.(too big.jpg) I bought the printer from the same seller, this is the one came with the printer(perfeby coldfront - Prusa i3 and variants
Quotemikez104 My aluminum bed came today. Might get a chance to install this weekend but not sure. I have way too much to do. Here are a few pictures. I bought it Tuesday and it came today so shipping was very fast. It is 3mm thick and weighs 312 grams.

Quoterich1812 Hi coldfront, thanks for such a uick reply. I have the hot bed on 12V, should I use 24V? Prior to buying the kit, I bought a 1.75mm filament, but it seems the diameter is too big for the Folger extruder, when I got the kit, it came with a roll of filament that 's much thiner, about 3mm. I am abit confused, the 1.75mm does mean the diameter, is that correct? When I look on eBay, soby coldfront - Prusa i3 and variants
Also for the heatbed did you place the - wire over both - 2,3 pads and + on pad 1?by coldfront - Prusa i3 and variants
Quoterich1812 Hi, I have some more questions. 1.) When I have the heated bed on and the temperature on, I leave it for about 10 minutes or so, than it would shut itself off, I can no longer move the axes. Is this some kind of over heat protection? If so, how am I suppose to print an object as printing an object likely take longer then 10 minutes. Is there something in the framework setting I needby coldfront - Prusa i3 and variants
Good Evening, Printer: Prusa i3 + Ramps 1.4 Configuration File: Voltage Divider Wiring: Sensor: I am at kind of a lost right now... I pruchased a LJ12A3-4-Z/AX 4mm NPN Proximity Sensor, and I can't seem to get it to trigger issuing a M119 command.

You wouldnt have the scad file or model file or can modify it maybe 10mm lower so the switch can hit my table and not heatbed, i really enjoy this endstop and dont really want to change the mount.. Quotejjbunn Yes, I put it on Thingiverse: Extended Y endstopby coldfront - Prusa i3 and variants

The thickness seems to be 1.5875 or 1/16th, few problems so far the holes don't line up.. hahah The length of the bearing holders are a bit longer so the screws don't fit through perfect, looks like i will be marking new holes and drilling them here soon. here is a attached photo with the old bed overlay on top of the new one.by coldfront - Prusa i3 and variants

Hey KeyserSoze3d, Did you design the Spool Holder yourself or grab the stl files from somewhere? If so could you post where you got it?
