I drilled a shallow 2.5 or 3mm hole and put some cheap thermal paste in the hole before inserting the thermistor into it and then a single wrap of kapton tape around it to keep it in place. Seems to be working fine.by AgeingHippy - General
sytex I guess you are looking for fire cement to fix your resistor in the heater block (personaly I would not follow the superceeded method of wrapping nichrome wire around the barrel and plastering it with fire cement. Anyway, I have a resistor in a heater block. The resistor has one or two wrappings of tin foil around it before I inserted it in the hole and it is fixed very tightly. No need fby AgeingHippy - General
looking foreward to it Mung. One question. What is a Mung License?by AgeingHippy - Plastic Extruder Working Group
I used fixed position, and have occasionally had failures in the middle of a print where the pinch wheel grinds away a section and hence loses grip and feed stops. I imagine using springs would push the pinch wheel into the ground away section so feed could continue. Having said that, the feed failure may have been for some reason that the springs keeping pressure would simply result in the entby AgeingHippy - Plastic Extruder Working Group
Hello All (or more accurately all you pro's) I am currently running my extrder stepper motor from the G3 extruder controller, ie. using the hack we all know and love (not) I am planning to use a pololu stepper controller instead. Will this reduce the heat of my motor or is it just going to reduce the whine and errant steps when it is supposed to be doing nothing? cheersby AgeingHippy - General
Hi aref Could you post the snippet of gcode that causes the error? I am guessing skeinforge is including a gcode not recognised by the firmware. Once you have identified the dodgy gcode you can use a file called replace.csv to replace the code with something innocuous, like an M105 which is a temperature request.by AgeingHippy - Skeinforge
@hradec I suggest you take a look at this post. In it Enrique states he is moving discussion to his blog and gives a number of links there. Maybe you should follow those links if you want to get involved in the software. I don't know if he monitors these posts any more.by AgeingHippy - RepRap Host

Nice one Sheffield RUG. It was good to eventually meet some of the big names and the 'Godfather' himself Also good to put faces to names and to see the variety of machines... 5 machines if I remember correctly, and no 2 alike lolby AgeingHippy - Sheffield RUG
I think there is a big possibility that this is just inertia - This is the diameter that was initially suggested on the wiki build instructions and hence most people are using it. I decided to start with 0.5mm because it was suggested and because at the time the smaller diameter nozzles were listed as experimental, with the possibility of moving to a smaller diameter nozzle later.

Dude - no need to shout at me! I am using a raft because I am unable to get my print bed perfectly flat. A raft produces a perfectly flat surface (in relation to my print head) for my object to be printed on. I am thinking of moving off the raft, but for now, and the point of this post is... ...are there any steps which will reduce the adhesion of my object to the raft or ease the seperationby AgeingHippy - General
lol I don't have problems with my stuff not sticking. In fact, the first layer sticks to the raft and it is very hard to seperate. I would like to get some guidance in how to reduce the adhesion between the raft and my object. I am printing in PLA at the moment.by AgeingHippy - General
I don't know how official or not this is, but I found a page asking for votes to select the Open Source Hardware logo. Check it out and vote over here And a bit of campaigning... I voted for the Iconographic Microchip logo. I think it is clean and simple and easily recognisable.by AgeingHippy - General
Hi All I am using a raft at the moment, and am finding the object sticks to it like ____ one a ___! Of course I want the first layer to stick, but I don't want to have to spend ages trying to seperate the object from the raft. Any suggestions? Cheersby AgeingHippy - General
Nophead uses a pushbutton or contact switch for his endstops. I have had a few crashes due to inadvertantly bending the tin flag on my X axis while maintaining the extruder - This makes me think a contact or push button type switch might be better... On the other hand, an opto switch with a flag might be easier to adjust.by AgeingHippy - General Mendel Topics
Sorry Andy. I saw this on the invite - I was just wondering if you could offer more information above what the flyer says.by AgeingHippy - Sheffield RUG
Do your X and Y axis home? If so, try connecting your z-motor to one of those axis's driver board and see what happens. Also, try pluggin the communication line coming from your motherboard to a proper working axis into the z axis board and see what happens.by AgeingHippy - General Mendel Topics

Hi Andy I wonder if you can tell us more about what the program is? I need to decide whether I take half a day off from work or if I only come for the evening session. Cheersby AgeingHippy - Sheffield RUG
Skip Skeinforge is an open source package which slices the STL object into sclices and then generates the gcode as required. IMO it is only really worth looking at once you have something to run your gcode on since much of Skeinforge is specific to your machine. As for people trying to sell you stuff... I guess that is in your private messages? I personally have not had any such problems and hby AgeingHippy - United Kingdom RepRap User Group
Although one can theoretically get any filament width (within reason) from a single nozzle by simply altering the head travel rate, I have found that if you try make the filament too thin by moving faster there comes a point where the filament is kinda 'pulsed' or results in thicker blobs with thinner sections in between... if that explanation makes sence.by AgeingHippy - General
I use retract speed of 10mm/s and retract distance of 1.0mm Seems to be working fine.by AgeingHippy - Skeinforge
I must say I found the gcode much easier to read when E was the distance extruded rather than the feedstock fed in... Also, I don't think the firmware is so big that we need to define the various parameters when compiling and uploading the firmware but could as brnrd suggests actually manage those parameters a variables set by the gcode. Perhaps as named parameters.by AgeingHippy - Skeinforge
I personally would not solder wires directly to the board. That makes maintenance a nightmare.by AgeingHippy - Controllers
once again Nophead is succinct and clears any misunderstandings. I just re-read brnrd's post and see he has decided to call it the Filament Drive Diameter Correction Ratio - so if my feed or steps per mm is based on the PLA, I need to modify the input volume (using the same steps per mm) for any other plastic since the plastic will experiance a different amount of movement due to the hardness/soby AgeingHippy - Skeinforge
Yes - I think the plastic inside the PTFE tube must melt but it obviously does not deform since it is being held in shape by the tube. I would guess the inspection was only caried out once the hot end had cooled down, allowing the feedstock in the PTFE tube to harden in the shape it is being held in. One way to determine this is to pull the feedstock out of the hot end and see whether it has defby AgeingHippy - Reprappers
I'm sorry - I don't see the difference. First let's make a distinction between my use of compression vs displacement. Compression as I use it is the plastic being squeezed so the same amount of plastic occupies a smaller volume - which must result in the density increasing. Displacement as I use it means the plastic displaced by the teeth goes elsewhere, possibly widening the feedstock profileby AgeingHippy - Skeinforge
