Re: thermocouple problem
need help - 12 years ago
Yes you can use different electronics but you are going to be doing alot of learning about whatever electronics package you use, as you will be wiring everything manually, you will have to set all of your pins properly in your firmware, and you'll have to setup your firmware to match the mechanics of your machine. It's not "hard" so much as it is time consuming. A RAMPS board should have hookupsby xclusive585 - General

Re: Hot End problems - 12 years ago
At the very least you need a new resistor as I'm pretty sure you fried the one you have when it was glowing... But you also need to figure out WHY it was glowing... a) (on a J head style hot end at lest) If you have the resistor inserted correctly, and it's insulated properly, I don't know how you could even see the resistor... b) It should never get hot enough to glow! If your hot end was noby xclusive585 - General

Re: Gada Prize Still Alive? - 12 years ago
I supposed if one really wanted to win the prize, you would need a team of many individuals each tackling one specific task. I see "20 cycles without refurbishment" as a gray area, and in the strictest sense that's tough. I pile on several layers of pva glue mix before cleaning and starting over, but that still requires doing something between every print... A material that could be printed on uby xclusive585 - Kartik M. Gada Humanitarian Innovation Prize

Re: Why Rostock? - 12 years ago
If you needed a basis for the most accurate builds, what would you go with, mendelmax, mendel90, other? I'm sold on Rostock I'm going to build one, but still not sure if I want a mendel90 or mendelmax(v2) or something else as my basis for a high accuracy unit... As for as the Rostock now I'm looking into the variants. SeeMeCNCs Rostock Max looks nice, just wish I could get the hardware withouby xclusive585 - General
Re: Displaced Prints and Projections - 12 years ago
Check all your pots Vref values. See where you are. you could just turn up your x/y drivers a little, or turn them all up a little if you want. But yes you never want your motors any hotter than "warm". Edit: don't overlook the obvious like slipping motor pullies.by xclusive585 - General
Re: Displaced Prints and Projections - 12 years ago
You definitely lost some steps on your x axis up at the end of your print. Could be curling pla getting your hotend stuck as was mentioned. (I'm still dealing with curling on some prints myself). If it wasn't curling then maybe you have your x driver set too low. As far as the pimples, some one with more experience needs to explain that. I dunno if it's normal, too much extrusion, temp related,by xclusive585 - General
Re: Why Rostock? - 12 years ago
Cool stuff. Part of the reason I'm asking this is because soon I'm getting enough motors and electronics for two more printers. My second build I have already decided will be nophead's Mendel90. Trying to decide what #3 will be. My ultimate goal for my machines is the pursuit of the finest quality prints possible.

Re: MakiBox $200 Complete 3D Printer

As much as I do or don't like Open source is not the issue here. Open source works, GNU proves that. There is nothing you can do with a Windows PC that you cannot do with Linux (besides OS specific wares of course). Reprap if it continues on its goals and development, can be the same counterpart to the big boys on the block as Linux/GNU is to Microsoft.

Why Rostock? - 12 years ago
What advantages does the Rostock type design have, vs. the traditional XYZ axis setup. It's a pretty cool looking machine I can honestly say I've never seen that type of design in any machine. It's quite ingenious. Smart use of math for sure.by xclusive585 - General

Re: MakiBox $200 Complete 3D Printer - 12 years ago
I disagree this is a fad. This is the beginning of a new age. Technology increases in complexity at light speed. In just a few years time we will have electronics so blazingly fast and able, that if reprap continues to evolve we will be able to do some really really amazing stuff. If it's not the reprap project it will be others, open source or not. In the end it would be nice to keep pace and maby xclusive585 - General
Re: Z Motors and Threaded Rods - 12 years ago
Around here, you will learn quick. Don't put the 608s in the Z stabilizer. Leave the bearing out so the bottom of the threaded rod is unrestrained and can wobble freely. As to the length of the Z rod, a little longer won't hurt anything except your threaded rod may be so long that it touches the table your reprap sits on, which you don't want. If anything you can make it shorter if you want, sinby xclusive585 - General

Re: Enable Cooling and an out of Control Heated Bed - 12 years ago
Or try PID autotune. Personally I did it twice each for my bed and hotend. Once with fans on and once with fans off, I then took the median of the two values, and have very very stable temps. 1°C variance. But the bed heats so slowly, it's curious why it would spike so high, especially with a fan on it.by xclusive585 - General
Re: Thingiverse "New" queue - 12 years ago
the IRC channel is great. I've popped in a couple times. Very helpful, and well-known people in there.

Re: Easy removal of support structures - 12 years ago

Re: Thingiverse "New" queue - 12 years ago
What about Githubiverse as mentioned earlier?

The beauty here is that the content is dynamically pulled from the github repository so it is always up to date. And, I don't need a thingiverse cloneby xclusive585 - General
