Re: 3D Printer Recomendations - 9 years ago

Warm fuzzies are addicting. Good luck. I'd just focus your scope, gas is expensive. If you wanted to 'rep-rap' you could always fund/micro-lend some teachers who could in turn organize their army of unionized workers to print sets and build even moar printers. Then with the money saved, you could visit the schools with your dirtbikes in the trailer In 'getting to yes', we are thinking of al

Are you going to sell the printers? (traveling salesman) Do you have grant funding? Are you rich? Sorry, but we raise these questions because you asked 'what's your favorite printer' where all you have to do is locate the largest sub-forum. "$500 however is within reach for many." If you are asking market research, just say so. Sounds like you wants to maek da sails $$$, and drive around

QuoteBoltazar I hate to be the newbee with a million questions, but I am.. We all were.

Re: 3D Printer Recomendations - 9 years ago

$500 kit price? Or build 22 printers with $11,000? There is a bit of a difference there. What do you currently print with? This might be one instance where parting it yourself could get you more bang for the buck? But if you get 22 of the same shitty kit from China, then atleast when you figure out the major shortcomings of one, you'll have a headstart on the other 21 Also, where does the

Re: Cura settings - 9 years ago

One thing that is always good to try after calibrating movement as you have done. Is to play around with the temperature a bit. Usually on the hotend side +/-5 is a good interval. On the bed, usually a little less drastic interval. But if the filament you are using is has a 30 degree range on it, a bisection search is probably faster. (I use cheapo Microcenter filament, so bisection it is).

Re: Cura settings - 9 years ago

Good job! Feels good, don't it. Have you already printed a Z axis fine adjustment knob? Maybe your printer came with one, but for the FT Prusai3 2020, it was the most important piece not present in kit or .stl files.

Re: Hictop Prusa i3 - 9 years ago

Do you have the ability to post pictures? Is the layer count of the print the same as the layer count of the slicer? While Z can be off by some, getting too far off would create layers that wouldn't adhere to themselves.

>Now when I plug my board to the lcd it lights up but It's blank. Is the Mega being powered by a separate supply, i.e. the computer., even when printing from SDcard. 1) I've noticed the RAMPs will backpower the LCD from the PSU for me, but do nothing (when I thought I didn't need to plug in the USB b/c I had it on SDcard printing). 2) Also, contrast can usually be adjusted by a potentiome

Re: Looking for some help: MK2 DIY build - 9 years ago

All I'm saying is for less than most postage, you can get a kit shipped to you. You'd have to mow the lawns of perhaps 3 people to come up with $30 (3 x $15 - $15 expenses), either way just a half-day's labor. 3Dprinting isn't just about self-sufficiency, it's also about making use of the products and byproducts of the greater economy, with greater efficiency.

Sometimes, going through Device Manager and disable/enable the drive works to get it to 'see' the port. Also, what is the Programmer set at? Mine is usually.

I'm assuming you are a student. That is for College students, but I'm sure you could look into HighSchool student discounts. Also, Ebay usually has someone selling a set for cheap <$50. Worst case scenario; mow some lawns, or move some dirt for a day and you'll have plenty of extra money for a set of plastic parts from someone selling them.

Re: Cura settings - 9 years ago

Also, that part in your picture where it separates and starts with a new origin halfway up the piece. Is usually caused by either: skipped steps (loose belt, or speed too high for your equipment ) /or XY physically hitting some sort of friction/immovable object that causes the missed steps. {I may have missed/skipped transposed? idk}

Re: Y steppers out of sync and extruder not feeding - 9 years ago

Quotecomarius Still feeding is still a problem. Sometime during print is either to much either too less. Do you have a picture of your setup? How much friction is in your filament path? Is your filament spool on some sort of ball bearing support?

Re: Cura settings - 9 years ago

Calibration models are your friend right now. You'll be printing many first layers and many tiny boxes till you get your settings down. The upside is that most the pieces can be printed in under 30min in cura. TL;DR: A small print will tell you just as much as a big print, and usually more, because you can spare 20min time increments to watch what is happening. Scale it (the model) down to m

Re: Cura settings - 9 years ago

I forgot what exact clone of Prusa i3, you are using. But if it is anything similar to the FT Prusa i3, then try using therippa's settings. I was lucky to be using the same model as him and it's pretty spot on for me. As far as the Cura part, what is your extrusion speed and filament diameter set at in Cura's 'configuration' page.

>Extruder starts to heat gets to 80c and then just stops heating How about when you try other things? Same result? I once had a 5mm thin wall calibration cube that was saved in g-code that repetier would do the same thing on, but if I printed other stuff, no problem. Also, does the repetier/sd reader, say 'job finished' or something similar after it heats up and stops?

First just set it waaayy too high, make sure stuff starts coming out (may take a minute or two). Then adjust downwards till you get a good first layer. If you haven't printed an adjustable Z endstop, that is top of the list. Royal PITA to get it close without one.
