Re: Heat transfer paste - 9 years ago
Quotedc42 The usual ones won't handle the nozzle temperature, but they are OK to use between the heatsink and the heat break. I thought so but couldn't remember the temps. Quotedc42 I don't think you need worry about the thermistor not being up to temperature. The hot end temperature changes relatively slowly, and most of the hot end thermistors we use have low thermal mass (so they will followby GRAYWOLF - General
Heat transfer paste - 9 years ago
While rebuilding my hotend following the burnout I started to think about heat transfer past (the stuff used to improve contact between processors and heat sinks. Would these paste stand up to the hotend temps and would they actually improve contact transfer. Current options are Silicon (normal cheep stuff), Aluminium (probably cause the least issues), Silver and copper past often used on cars.by GRAYWOLF - General

Re: FIRE! - 9 years ago
Quotemadmike8 There is a Safety section with some really good information. Fire is a real fear with these DIY printers, so be careful and watchful. I work in the fire industry so always have a fire extinguisher close to hand The cause was the sensor coming loose!by GRAYWOLF - General

That's it im done, I have had enough now. The new heater just set fire to the protective cover on the hotend. I can't be bothered now!by GRAYWOLF - General

Quotedarkechibi please bear with me. I bought this as a kit, the nozzle/extruder is using 1.75 PLA. If you can tell me how to determine the data I need to get I will do so. What is the um in the 200um measuring, how much smaller is possible? is any? Where can I get the smaller nozzle I need and how hard is it to make the changes.

Re: Bulldog Lite Extruder Replacement fan? - 9 years ago
Quotechrisbob12 I fried my Bulldog fan by connecting it the wrong way round (despite reading that it needed to be connected red +ve etc durrr) I looked at the suggested replacements above and they look promising, however, RRD sell the replacement fan unit. The prices for the proposed substitutes are very similar to RRD, and the Mouser shipping cost is very similar to RRDs. I went with the RRD uby GRAYWOLF - General
Re: Watch your hotend cables! [FAIL] - 9 years ago
QuoteJamesK Look on the bright side, your bed adhesion must be excellent! Just Kapton on glass QuoteEpop That's pretty awesome! Most would pull the part off the platform and you would end up with a rats nest. Yep... how your wires are routed is pretty important... especially around/on/connected to moving parts. Lol, did that last time the print head failed.by GRAYWOLF - General

Check all your settings in the arduino ide, check all your setting are correct in firmware and try uploading again. The good thing about arduino based printers is that its very hard to "Brick" themby GRAYWOLF - Prusa i3 and variants

Re: Puzzled by Pronterface and Repetier - 9 years ago
QuoteHSBallina QuoteKurzaa As a safety precaution, you can't extrude filament unless your hotend is heated to at least 170 Celsius. It is a setting in the firmware. My guess is that there is a similar setting built into Ponterface in the event that your firmware doesn't support the feature. Not sure what the issue is in Repetier-Host. Did everything but extrusion work in Ponterface? I edited thby GRAYWOLF - Reprappers

Re: USB connection to Ramps 1.4 - 9 years ago
To upgrade the firmware you use the arduino IDE (Arduino.cc and not that other fake wannabe site) You should have 2 box's one for interface type and one for baud rate. have you tryed the changing the interface type? I have had my report that it was a modem once!by GRAYWOLF - General
Re: Extruder overheating and slipping? - 9 years ago
Quotejbernardis Your message isn't clear here. It sounds like it's not the hot end overheating, but the motor. If it IS the motor, then it is overheating because you are overdriving it. This same thing happened to me; the motor overheated to the point where the small gear and the extruder body both deformed. Also, I couldn't touch the motor for more than a second or two.

Layers split because there too small? - 9 years ago

Extruder overheating and slipping? - 9 years ago
I'm (still) running a bulldog lite with a fan between the hotend and the motor but notice a problem that Im getting a clicking sound from the extruder and it seams to be slipping on the filament. The cura settings are set for a 0.4 mm nozzel with the exception of nozzle size, I've linked 2 screen shots. Am I missing a setting that is causing the extruder to overheat and skip?by GRAYWOLF - General

[SOLVED] Esteps fail with bulldog lite. - 9 years ago
After a week of wanting to smash my printer I have it up and running again but for one issue. Running Triffid hunters calibration test I am coming a cropper with the esteps calibration. The i'm running it with the hot end but the extruder is clicking away and only extruding 95 mm instead of 100 mm (or near enough), Is this down to the pully not having enough pressure on it or back pressure fromby GRAYWOLF - Prusa i3 and variants
