Just to make this a fact, with the brand name you say 'Reprapper' Do you maybe mean Repraper? Because I have very good experiences with Repraper filament. The Dutch reseller www.filamentenmeer.nl is where I got it from. The thickness varies sometimes yes, but I have never noticed in my prints. They are up to standards and the ABS from Repraper bridges very well for me. Also the PLA I got from thby Ohmarinus - General

So, bottom line is you just have to sign up for the army, make one disappear and then take your leave Haha, okok, I'm not trying to set one up for illegal activity, but for this price it's just 'too good to be true'.

Your message is close to abstract. What program are you using? And does it give any error hint?by Ohmarinus - General
I have the feeling that just using kapton over the hole when the thermistor is in, closes it off enough. And then I add one layer of ceramic insulation over the whole brass block of my J-head to finish it off nicely. Can't go wrong with thatby Ohmarinus - General
Als je stappenmotor terugdraait, dan zou dat ook retraction kunnen zijn. Als je stappenmotor zelf echt tikt, dan staat de extrusion/retractionspeed te hoog. De firmware is zó ontworpen dat je extrusion speed de bepalende factor is in je printsnelheid. Alles wordt daarvan afgeleid. Bij mij hikte hij bij retraction speed, dus heb ik de retractionspeed naar beneden bijgesteld van 40mm/s naar 30mm/by Ohmarinus - Dutch User Group - Archive
Wat gek, bij mij krijg ik een foutmelding als de temp sensor niet is aangesloten! Dat helpt wel erg bij probleemoplossing.by Ohmarinus - Dutch User Group - Archive
Hello, I am rethinking my 3D-printer at the moment, it's a MendelMax 1.5/1.6 (1.6 being my own design at the moment with vertical X-axis). I cannot find out much about this subject, but I am wondering, why are the Z-smooth rods always placed on the outer sides of the machine? And second to that, why is the X-motor positioned to 'hang' a bit on one side of the X-axis? For me it would be more logby Ohmarinus - Mechanics
Well, makerslide is always sold-out every time I've been looking for it, which has been multiple occasions last year and now again in europe it's sold out. Shipping cost for a single batch is too high, so that leaves us with using those smooth rods again.by Ohmarinus - General
I took a chance and bought repraper black PLA, really curious how it handles. It came into the post-office today, so still have to pick it up!by Ohmarinus - General
Quoteecoreprap AliExpress is not so friendly,one reason is that they charge 5% for the seller the other is that the logistic is very slow. 5% is not that much, they offer local companies a place to sell their wares on the intercontinental market. To me that sounds like a good deal. If you want to hire a stand at a convention you will pay more.by Ohmarinus - General
I don't think MM1.5 is very popular, there is virtually no activity in that subforum for extruded alu printers That might also mean that a lot of people who work with extrusions know what they are doing, in contrast to the 'new' people I see coming around all the time saying they can't get their Prisa i3 to function (this is not a complaint btw) And for that reason, the Prusa i3 seems to be tby Ohmarinus - General
The magnets are arranged in such a fashion that every next magnet is turned around so they alternate between + and - and this causes the wheel to spin without much friction, and added to that, the magnetic fields are a bit 'locked' into eachother Indeed, the kinetic energy in the discs is bigger than the attraction in the magnets when they make quick movements so slippage is possible. Today I wby Ohmarinus - Look what I made!
Most popular would be the Prusa i3 I think.. At least at this moment. To be honest, I find this a bit of an impossible question as it comes down to personal preference instead of factual information. Don't you agree? There are so many factors that make one option more popular than another. For me, the most elegant machine is the Berrybot, the most viable one, the MendelMax and derivatives/evoluby Ohmarinus - General
I was sitting in the bus, thinking of gears for an extruder, however, I didn't come up with a usable solution, I did manage to design my own gear system with two gears that spin with nothing in between them but magnetic fields. Hope you like it: The advantage I was thinking of would be that the wheels don't have any kind of wear because they don't have teeth, the only thing wearing would be thby Ohmarinus - Look what I made!

So I just went on to amazon and bought:Flame Defender - 12 KG - 7.7' coverage I don't worry as much about the type of short OP had but more the idea that the thermistor fails and a run away hot end ignites plastic. Add to that the can of Acetone that is generally there. I lby Ohmarinus - Safety & Best Practices
Well, it's nice to think about materials. I have been playing with 2-component PU-materials. Making castings with all kinds of different things. Ofcourse, this is not usable for a 3D-printer, but I'm pretty sure that there must be a material that can withstand heat, and still not become very toxic at the same time. I think thats one of the reasons why they use PEEK and PTFE. Low toxicity with theby Ohmarinus - General
Quotedave3d My approach is to speed up the print as much as possible so there are no overnight prints. I have an Ord Bot which is pretty fast anyway but I have Bowdenised it to get it faster. I think if long prints are necessary the way forward is to fully enclose the printer and have an auto shutdown and extinguisher system. Add a CO2 extinguisher to the box! Those things work magic and the beby Ohmarinus - Safety & Best Practices
Z-height, bed temperatuur, bed ontvetten met aceton, verkeerde surface als printbed etc. Allerlei factoren die dat kunnen veroorzaken.. Zelfs een te lage extrusietemperatuur.

Quotejpan Why not just print a plastic container that can holds water and put it right above the RAMPs board? Just remember to unplug the PSU first when you see it's burnt? Did you ever hold a flame under a balloon? I'm sorry I think this is only making the whole plan more dangerous. I don't even dare to put a glass of water next to my printer!

To be honest, I'm doubting the plus value of this thing. And I really don't get what they mean with that you don't need kapton to fix the ceramic heater and thermistor?by Ohmarinus - General
So, in short, you're trying a 3mm filament extrusion with a Direct Drive? Because anyone knows that that doesn't really work out with a NEMA17 stepper..by Ohmarinus - General

I think you are missing the overview. Great improvements are made on different parts every week! New kinds of hotends, new ways of extruding, new plastics, new vitamins, new electronics, new designs for X-ends and X-carriages, new materials for print bed surfaces...by Ohmarinus - General
Hi guys, I just wanted to show you something I found on the web today while looking for a J-head: Would this work well do you think? They live in Belgium, so for me it's pretty close (Holland). Their geared stepper is also quite affordable. Anyone has experience with this ceramic zirconium insulator?by Ohmarinus - General
