Re: Things aren't sticking! - 15 years ago

I've had good results (so far) with 4042D natural PLA on dibond fr + 1mm aluminium + PET tape, and no heated bed. Wash down the tape with some alcohol, heat it a bit with a heat gun (hairdryer?), start the print with the head low to squish the filament a bit, then continue to heat sparingly during the first layer to make sure you get a good adhesion. I use this cheap PET tape: ( wider version av

Re: Reprap-Compatible grease - 15 years ago

http://reprap.org/wiki/Lubrication seem to favour PTFE grease, like the brand "super lube". I've acquired a tube off ebay, but have yet to test it. From the bottom of that wiki page: "Silicone grease that is often used with RepRap is actually meant to be used with rubber gaskets, o-rings and similar equipment. It is not "bad" and some users report good results with it. There is also silicone grea

Thanks Scorpia, good to hear. The "worse for wear" bit might have been my terrible packaging skills. At at job I had, I was banned from giftwrapping for customers, because of the look on their faces. Oh well, 5 sets sold so far, get them while they last.

Re: knotted string for belts? - 15 years ago

For the x and y axis you'd only need knots for a portion of the length. I can't find it, but I recall a discussion about using plain rope. If the rope has enough texture or grip, it should be possible. Although, I'd be more concerned with the rope stretching, knots or not.

Re: Another extruder concept - 15 years ago

I like it, but wouldn't the need for the motor to always turn back and forth work against the (more or less) constant pressure needed for a steady extrusion flow? This could perhaps be countered in software to either wait for the motor, or run backwards between extruder stops or layers. Or in hardware by building a long "grip" area. But wouldn't it be difficult to lay down one long straight bit

Re: Wanting to do Mendal for my Dissertation but can't think of any new ideas, any suggestions? - 15 years ago

Rhys: Wouldn't the objects come out slightly malformed this way? Imho, using a raft circumvents the problem in a better way, in the case where you can't make a level bed. RepRap_GCALman: From the top of my head: I'd love to control my RepRap(s) via LAN/ethernet. And more ways to detect a hardware or software malfunction and stop the printer automatically would also be a great addition.

Re: extruder help - 15 years ago

Try pressing the reset switch on the extruder controller, as well as the motherboard. The heater probably starts at 28C because that's the room temperature. :-)

Re: Mendel build assistance HELP - 15 years ago

1: From Build Envelope 200 mm (W) x 200 mm (D) x 140 mm (H) You can make it a little larger (or smaller) if you get creative with your endstops. 2: Why would it matter? Mine extrudes about 35mm on the non-opto side, a bit less on the other, but my bed might not have the standard size. 3: Depends on what extruder you use, and how you mount it.

Re: Gen6 AI1B, heated bed controls? - 15 years ago

Camiel is a PLA-only guy. And there is no need for a heated bed when you use PLA, just use lightly sanded kapton and a hairdryer for the first layer, and clean the bed with some alcohol now and then. Using a heated bed to print ABS on a PLA Mendel would mean dangerous temperatures for the carriage anyway.

Re: RepRap Host Temperature differences - 15 years ago

If I understand it correctly, you only need temperature.h on the extruder controller, as it controls the temperature and sends the readings back to the mb. I had the same problem when I updated my firmware. I believe it must have been from me forgetting to save the correct file or something. I'm sure you did, but double check that you really have the proper temperature.h, and that it uploaded cor

Re: knurling knowledge kneeded - 15 years ago

I've had the same problem rocket_scientist, and have made a couple of bolts this week. With good help from #reprap this is how I do it: First I mount the bolt in the extruder and mark where to the cut. (I like to use the nuts on the gear side for easier disassembly).Then I secure the bolt in a power drill, with the head sticking out.Without the drill spinning, I file a V-shaped groove in the bo

Re: Binding issues with Z leadscrew/washers - 15 years ago

I had the same problem, but solved it by pushing the m4 washers as far out as possible while centring the m8 washer.. A friend of mine got some m4 locking washers (the not-perfectly-flat type with dents in them) which was a lot smaller than the standard ones. Might be something to look out for.

[NOR] Mendel bearing kits - 15 years ago

I just put up a set of Mendel bearings on the norwegian auction site QXL here: qxl.no The set includes 50x624zz and 2x608zz. That makes it possible to assemble Adrians geared extruder. If you need the bearings for Wades extruder as well, I might add them for free if you ask me nicely. Sorry, I've run out of extra 608 bearings already.

Hi Craig For the thick parts, I'd like to recommend the squashed froglet by nophead : http://www.thingiverse.com/thing:2107 I made mine from some acrylic I had lying around and it looks great, but is a bit on the wobbly side, so I'd take nopheads advice and make it in dibond.
