Not only would the motors be prohibitively expensive, the hit on print speed would be significant. Resolution is good, but you get diminishing returns once you pass a certain point.by sheepdog43 - General
Again, you have to look at the whole picture, cost of other parts, reliability, accuracy, maintenance, etc... In the grand scheme of building a good, reliable printer, that's not a lot of money. More importantly, you are trying to save a few dollars on a multi-hundred dollar object in a place you can't just simply swap out later. This is an important part of a delta, are you sure you want to cutby sheepdog43 - Developers
As much as I dislike wood, the Ultimaker is actually one of the few printers I was impressed by. It's actually stronger, and holds it's calibration better than many/most Reprap designs I've seen and worked with. Add up the price of special rollers, bearings, shafts, spacers and shipping, then go compare it to the cost of V-slot, because you need the whole system in order to make it work.

Check your belt pulleys, one or more is probably loose, also make sure your bed is held down tight.by sheepdog43 - Delta Machines
Had this exact same thing happen on one of the all metal hot ends we tested. We never tried oil, but we always used a fan. Leaving it on after prints didn't help at all in our case.by sheepdog43 - General
Certain designs lend themselves better depending on build area and footprint. Quality can be achieved on most designs, it's a matter of how fast and what your needs are. Deltas: Cheap, fast, reliable, easy to assemble... for a single nozzle setup. Not so good for duals, they work best with a light weight moving assembly. Can be more difficult to tune and have a lot of wasted upper space. CoreXYby sheepdog43 - Developers
First check your temps, that is where I would start. The temp reading is not an actual number but a reference as they are highly inaccurate, what reads 210 on your printer, could be 120 on another. Disconnect your extruder, run the hot end up to temp and see if you can push filament through with your hand. If you know it's not clogged, and cannot get it through, up the temp.

I have yet to be impressed with some of the newer scanners in general. Look around Thingiverse at scans people have done, and look at what they used, that will give you an idea of what to expect. Some are not impressive at all. Filastruders are not super simple or fast, getting a good extrusion takes some work. As mentioned you will also want a winder, and if you want to recycle prints you alsby sheepdog43 - General
FSR's are very fickle, we spent a long time getting ours working even remotely decent on our printers. It took 2 months on our XL and 3 months on the smaller printers before we had a system of bed mounting/fsr mounting that we liked and worked. Usually when there is an issue with something, you hear lots of complaints, but for some reason, that doesn't seem to happen much with RepRap printers. Mby sheepdog43 - General
For Ramps, you can usually get away with 5 or 6 amps. The board cannot handle passing more than 20 amps (including heated bed), and I would say even that is pushing it. However, the board will only use what it needs, so your power supply should work just fine. It's more than enough power.by sheepdog43 - Reprappers
I have seen someone try to print V-slot, it was... interesting. It printed, but it wasn't very useful. I'm all for making printers with what you have and as cheap as you can, but the reason printers have moved the directions they have is because you can only get so much precision with cobbled together junk you find. Reprap is a great idea, and someday will likely be possible, but you can only dby sheepdog43 - Reprappers
Just because you CAN print something, doesn't mean you should. This is one of the most important parts of your printer, and in the grand scheme, one of the cheaper parts of your printer. Saving money here, will only bite you hard later.by sheepdog43 - Reprappers
Printing too fast, too hot, or insufficient cooling air will cause PLA to curl on overhangs and corners.by sheepdog43 - Reprappers

Every design has it's pros and cons, using two screws has disadvantages, mainly in leveling. You cannot lower or raise your bed by hand without destroying your calibration. They do however increase leverage, but watch the weight and "racking", where it gets knocked out of shape. I was never a fan of that system and after having used it, I was even less enthused. Linear bearings work well, but yoby sheepdog43 - Controllers
Awesome! My advice, do the lower frame connectors last. You need your printer well tuned to the plastic before doing them or you will have problems. People seem to have a lot of trouble printing them. They are straightforward, they just seem to trip up a lot of printers.by sheepdog43 - Delta Machines
There are a few issues you may need to address, I'm not an expert on large cartesians, however I do build deltas similar to this in size. While you are short of what I would consider large format printers, you are on the cusp of it, and things just aren't as easy as "I want bigger", in fact you will be surprised how quickly they spiral beyond what you expect. This list is by no means comprehensivby sheepdog43 - Controllers
You're welcome. We are only selling complete printers at the moment (pre-sale), parts are coming, but we need to focus on our Kickstarter people first. Tridprinting can do rods and the effector is interchangeable with the Mini Kossel. I'm pretty sure there is a Mini Kossel dual head effector out there, just use that, it will bolt in. We are using FSR's/auto leveling on the Pro model, but unlesby sheepdog43 - Delta Machines
Some deltas do have banding issues, just not the same way as cartesians. In both cases though, I think some of it is due to the digital nature of 3d printing, look at banding on low color pictures, same thing. The finer your step resolution, the better your prints will be. As for quality, it's pretty simple. Most printers of similar design will always print similarly because they use the same elby sheepdog43 - Delta Machines

This is a bit jumbled, but I hope it helps. First the good news.... There is also the original Griffin (OS), the Open Source/Reprap version. Both it and the Pro were designed to be scalable. The only other delta truly designed to scale well that I know of is the Wolfstock, which is better for sizes as large or larger than the Griffin XL. The XL though, is pretty much the largest Delta (and cby sheepdog43 - Reprappers
Quotearthurwolf Quotesheepdog43 It just needs a bigger brother now (dual extrusion!), otherwise, we have been quite happy with it. The Smoothieboard 5XC has all you need for dual extrusion ( and was designed with that in mind ). It's close, but it doesn't do 1/32 native stepping like the Azteeg X5, which is what we use on our printers.by sheepdog43 - General
Quote3DRapidClone The Griffin Printer printed parts have grooves in them to have better contact with the V-slots. So unless you modify all the files, which would be horribly inefficient. I would say go with something else. Standard 20x20 might fit, I will have to look. As mentioned though, it would eliminate some of the benefit of the Griffin design.

Quote3DRapidClone Are the traxxas and losi joints equal in terms of handling that kind of speed? Im not sure if the cherry pi effector design can handle that speed either.

I forgot about this thread... We've been using the X5 for a while so here's an update. Simply put, you would have to pay me (A LOT) to go back to Ramps. The X5's not even in the same league as the old Ramps boards, they seem archaic compared to this, it really is that much of a step up. It just needs a bigger brother now (dual extrusion!), otherwise, we have been quite happy with it.by sheepdog43 - General
Quote3DRapidClone Here you go, everything is neatly documented. It's a reprap, It's a Kossel Mini derivative that uses V-slot, and different ball joints, its similar to Ultibots, but ultibots uses a PG35L micro direct drive extruder. Griffin is designed for Geared Stepper motors. The extruder is a dual system, it can use a standard Nema 17 or a geared Nema 16/17stepper. I don't recommend the nby sheepdog43 - Delta Machines
Quote3DRapidClone Actually, I do have a question since I've been pondering whether or not to build the Griffin due to its high speed capabilities. How does v-rollers handle that kind of high speed, i.e. (300mm/s +) Because I am willing to pay that extra money for linear rails if it helps, though noisy?

Quote3D-ES You are correct, if one of the tower screws unscrews itself, there is a problem, no backup there, but I think that the screw that is used to lift the top keeps it from lowering if it comes loose..?

Nema 23's are not supposed to be driven with standard Polulus, you probably will need an external driver, such as a Gecko driver. 23's are typically higher stepping rate and need more amps, sometimes different voltages as well.by sheepdog43 - Delta Machines
