Great job on the mag guys! Great reading. Can't wait for the next one.by xclusive585 - General
QuoteI also learned from my open source adventure, in that releasing a robot to open-source before you sell it just kills the robot. Yea, that's what killed it. All of those other companies out there producing your design. Riiiiiiight. Must be nice living in such a cloudy dream world. Has to be cozy in there.by xclusive585 - General

On lots of pololus out there, (cheap ones like I own) there are no stops on the pots and they will turn all the way around. That doesn't mean anything is broken.by xclusive585 - RAMPS Electronics
A well made counterfeit should function just fine, if made by the right people. Our primary objection to counterfits is that they claim to be something that they are not, when they could just as easily give them a similar name and call them a 'clone'. As far as if what you are looking into is real or not? I can't tell you.by xclusive585 - RAMPS Electronics

1. You only have 3 endstops because you only need 3 endstops. By large in general most repraps are setup to only pay attention to the endstops during the homing process, after that it keeps track of everything by the number of steps it has sent to the motors. Therefor if your firmware is set properly for the size of your machine, your axis will not be allowed to move beyond their max position (unby xclusive585 - General
That is a tasty burger! If you know the specific amount of shrinkage you are getting, convert it to a %, and scale your stl to compensate? Just a thought. Your shrinkage will be different in different axis I assume so this won't be a perfect fix. Also, are you sure while it's printing that it is actually the size it should be? Maybe it's already a little small while it's printing, which is aby xclusive585 - Reprappers

That's probably a bit too tight. You want it tight enough to drive the filament without the hobbed bolt slipping, and you want your E motor tuned low enough to skip steps in case of a jam, rather than strip the filament.by xclusive585 - General
It should also affect the speed on the travel to the endstops.by xclusive585 - General
Quote...it's used now mostly to control/prohibit competition Exactly. It's freaking rediculous too. I'd love to see the balance of power leave the big corporations (who are now getting too bloated to produce goods affordably) and return to the individuals. But this would take reform, and perhaps an abandonment of the existing patent systems. This of course will be fought to the death by the bby xclusive585 - General

what bravach said. Incorrect steps/mm on Z.by xclusive585 - Printing
I think one of the issues we see with that design is the Y axis is supported in such a small area, this leaves room for the bed to flex when Y is at a minimum or maximum extreme. Especially if those are 8mm rods and LM8UUs (and they look like they are), you could see a x/y axis that has more play than a prusa.by xclusive585 - Reprappers
One direction movement is a sign of endstops wired improperly or bad settings in firmware for your endstops. IF a + movement moves your motors towards the endstops then you may need to reverse the motors polarity.by xclusive585 - General

If someone were to write an article and submit it to you, will it at least be considered for inclusion in an issue?by xclusive585 - RepRap magazine
+1 to the too much cooling cause, as well as hotend temp too low. Both of these have the ability to cause poor layer adhesion. But in the OPs case, as few details as we have, he says they are breaking as they get taller... This leads me to believe he is using an improper steps/mm (too high?) Which is causing the layers to get progressively further apart in height as he prints.by xclusive585 - General
