As the title says I'm getting selling some old stock on ebay so please have a look: 50m of timing belts (t2.5, 10mm wide, 50m length) 40 hobbed bolts: You can send me an offer if you want... Mikeby michaelc - For Sale
Cool, yea... its working. are there any other options, to make the results public?by michaelc - General
thank you redreprap, although unavailable for me.by michaelc - General
I dont see the problem, Id rather it was done well than quickly. On the topic of keeping it simple, couldn't you of embedded it with code which allows us to see the results? Quote The more questions you put on a survey, the less people will respond did you do a survey to get that answer?by michaelc - General
QuoteRedreprap see approx amt used per year, percieved consistency, price etc hahaha How would you word that? Approximate Kg of filament used per year? Do you prefer to buy your filament: By the meter On a reel Dont mind What is the most important consideration when buying filament: Cost Colour Low cracking after printing Low warp whilst printing If you have purchased from low cost Chinese/oby michaelc - General
If it can't be done, there are a few basic poll scripts which can be pasted into a thread like: impoll.net or some better polls could be pasted into the wiki. Are there any questions people would like answering about the community, a few polls might be really good to gauge where things are?by michaelc - General
Hey DeuxVis, can you move this to the appropriate forum, I didn't spot it in the first place. Phorum apparently doesn't do polls.. but can be added as a module, it might be a good feature? I've discussed it with the manufacturer, but the picture isn't clear - they're mainly dealing with companies, mostly non-reprap users. thanks, Mikeby michaelc - General
Hello Admin, can you possibly run a poll in this forum on filament types people are using? I've been talking with a good manufacturer (of the higher quality filament) about getting some better prices for the community. I was under the impression most people were now using 1.75 PLA - but I think this is just my experience, ABS, PLA, PVA, PP, HDPE 1.75, 3mm Thanks, Michael - Thingfarm.comby michaelc - General
Hello, We've put together a high spec 3d printer based on Mecano's Air frame.. It's working really well and producing some high quality prints. I'll be spending the week printing out some stuff so i'll put some on here.... I only have hundreds of prints of bland parts and no interesting stuff. The plan wasn't to sell the machine however we have some ideas for an advanced nozzle design and weby michaelc - For Sale
I'm using ramps 1.4 with a CNC 30A 12V, PCB heatbed, currently with a kettle lead but I want a switch, does anyone know if a lamp lead with a torpedo switch would be suitable? or any other ideas...by michaelc - RAMPS Electronics
Quoteidolcrasher It might not be completely pure PLA? I think its the opposite mate, I think Chinese is pure PLA + dyes, I emailed KDI about their filament: "Our filaments are 94% PLA and also contain an additive to improve the flexibility & stabilisation which is unique formulation to KDI and will aid help to reduce brittleness and increase shelf life due to the improved strength of thby michaelc - General
Hey Idolcrasher, I've bought from Chinese suppliers before, the price was unbeatable but the quality varied... one time I found woodchip in the filament, most of the time the thickness varies, etc. I've got a few 2kg reels I won't touch unless i'm really desperate. They will continue to innovate however... especially when people are making so much money from selling the good quality stuff. Thby michaelc - General
QuoteNophead I think you are working it out wrong. Arctic white say is £24 for 100m x 3mm, which is 880g, so ~£27 per Kg. Expensive but not ridiculous. Sorry... I didnt specify filament size, I was referring to 1.75. I used their 'Crystal Clear' as an example as its the cheapest at £18.00 per 100m which they state is approx 300g... so £60.00 per 1kg or £90.00 for 1.5kg.by michaelc - General
Hi, I know the won't tell where the get it from - they're making a killing, but there can't be that many manufacturers? The prices are double or more of other places when you work it out per kg. I agree they're good quality but I think they biggest draw if the variety of colours, I know at least one other manufacturer which does put in the R&D to make good filament with the right characterisby michaelc - General
Hello, I spoke to them on the phone a while back... and then they said it was from the biggest supplier in the UK and it wasn't KDI polymers, however that's all they would tell me. I'm not sure if what they said was true or designed to put me off digging. I love the quality from these guys... however it's overpriced and I want it on a spool! Does anyone have any ideas? cheersby michaelc - General
Hey, thanks for your suggestion, I thought I recognised your username I would like to avoid buying a coupling so i'm going to try the other one, with a bit of glue if required. I've got an idea how to make the holes align so the filament can feed properly. If it doesnt work then i'll try out your design! thanks, Mikeby michaelc - Huxley
They are machined and the files are there in the github, as you suspected. I'm going to try printing a coupling instead, probably similar to this:by michaelc - Huxley
Hello, I'm after the same fittings as used in the RRP huxley/mendel bowden extruder - however they haven't got any in stock. Can anyone suggest an alternative supplier? I'm not sure if they're machined or off the shelf. thanksby michaelc - Huxley
Thanks for your help. Rich: I tried the resistors, however this did not work. Andrew: The heatbed has 1.5ohms, I'm not sure what its supposed to be. Cynar/Nophead: thank you for the explanation, I'll have to go down the power resistor routeby michaelc - General
Rich: thanks for the tip, i'll try this this evening. Cynar: for safety reasons i'm using PC PSUs, one is a fairly high spec. There will be children/young adults in contact with the machine eventually. I'm not sure what you mean by overloading, I think the PSU just thinks its shorting due to the low resistance of the bed - at the moment i'm attaching the PSU directly to the heatbed.by michaelc - General
Hello, My power supply unit keeps cutting out when connecting my new Prusa MK1- PCB heatbed. I've been told that it's due to the unit not detecting any resistance due to the low resistance of the heatbed. I have now bought and tried three types, and they are getting progressively more expensive. I have also added a few resistors. A high powered resistor would work but it would be too hot anby michaelc - General
Hi everyone, thanks for your help. In the end it was the resistors causing the problem - since moving to the vitreous enamel type the issue has been resolved and temperatures have become more stable. They are still recommended on the Geared extruder nozzle wiki page. thanks, Mike #edit: admin please move this somewhereby michaelc - Firmware - experimental, borrowed, and future
Hi, thanks for the replies. I've tried a few things over the last few days. - I started to think it was my fault using the exhaust putty, so I've tried fire cement and aluminium foil to fill the gap between heater block and resistor, still the resistors have blow out. - This is the resistor i'm using, i've heard a other people have used it successfully. - I am using a 12V pc power supply.

Hi Viktor, I'll be able to measure the temperature once I get some more resistors.. I lost another one this morning. I think the thermistor values are accurate however and the temperature is fairly stable after heating up. When heating it rises to 270 before stabilising. It also only takes around 20 seconds to heat up which seems too fast. Can I reduce the current within Sprinter? I noticed tby michaelc - Firmware - experimental, borrowed, and future
Hello, I've got my PRUSA working quite well however my extruder heater resistors keep burning out after a few uses (5 so far!) I'm using Sprinter on Sanguinololu with Pronterface and RepG. Is it possible I haven't set up Sprinter correctly, is there a way to reduce the power to the heater extruder? The resistors work well with other people. There is good contact with the heater block with exhaby michaelc - Firmware - experimental, borrowed, and future
I've been thinking about trying out some nozzles wider than .5mm, could anyone tell me their experiences? - Can I produce prints quicker? - Is the resolution vastly different? Mikeby michaelc - General
The thermistor table is correct and selected. I had no problems with previous firmware on Gen6, same set up. Is there a way to limit the power to the heating resistor from within the firmware? Mikeby michaelc - General
Hello, my extruder heating resistor temp is rising very fast despite having a skeinforge heating rate of 0.1 Celcius/second. This means it's over heating and fluctuating wildly. Can anyone advise me how to slow it down? Ponterface/Sprinter + Sanguinololu thanks, Mikeby michaelc - General
Thanks for the message, I noticed your post after writing the above and the bug report is appreciated, hopefully they'll have a look at it. I've moved over to Pronterface because of this problem... it's a shame because I really like RepG.by michaelc - Sanguino(lolu)
I have the same problem with sanguinololu + sprinter, thanks for filing the ticket.by michaelc - General
