Yea, 17A is plenty for the motors/etc. But if you want a hotbed, I'd recommend finding a supply that's higher than 250W total. Maybe 350+by ShadowRam - General
I'm new to all this so I'm just guessing based off my reading/research. Maybe 60degC bed temperature too high? I thought a lot of people were printing PLA without a hotbed at all.by ShadowRam - General

Sounds like the Temperature PID needs tuning. In your Marlin Configuration.h, What are these values set to? #define DEFAULT_Kp #define DEFAULT_Ki #define DEFAULT_Kd (I'm guessing the proportional part isn't high enough)by ShadowRam - General
This is all open-source right? We are all sharing information here correct? This is a thread about Metal Hot-Ends is it not?by ShadowRam - General
Looks like the Marlin Firmware has what I need. I found in Configuration.h Quote // ENDSTOP SETTINGS: // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR -1 #define Z_HOME_DIR 1 #define min_software_endstops true //If true, axis won't move to coordinates less than HOME_POS. #define max_software_endstops true //If true, axis won't move to coorby ShadowRam - Reprappers

Pretty neat little unit. Would definitely make it easier on the people that aren't familiar with electronics to get into small DIY 3D Printer. I hope there is some decent protections in those stepper drivers. I'd hate to see someone blow one, and not be able to easily replace it.by ShadowRam - Reprappers
None of these really answered my question. My machine isn't a standard RepRap. It's a custom. This video might better show the setup http://www.youtube.com/watch?feature=player_embedded&v=E_mMcdNbK4M Right now, the Opto End Stop is at the TOP of the Z-Travel. So what I'm asking is, Do I leave it there, and can I define somewhere in slic3r the starting Z-Point (aka 150mm from the endstopby ShadowRam - Reprappers
Yes, All 3-axis are working https://www.youtube.com/watch?v=E_mMcdNbK4M and just today I have the final pieces to complete the entire extruder.by ShadowRam - Reprappers
Where does the Z-min endstop usually go? At table height? or can I use the end stop at the end of travel and define the table height?by ShadowRam - Reprappers
QuoteRun the same code again, increasing the 'F' value by perhaps 5000 each time, up to 30000. This is mm per minute, so 1000mm/m = 16mm/s, ie pretty slow! 30000mm/m = 500mm/s, ie very fast! Speed is actually limited to 500mm/s in firmware. Record at what speed it stops moving smoothly. DOH! That's why I can't get my system to go faster than 30,000mm/m. Where do I find that limit in Sprinter?by ShadowRam - Reprappers
I'm also from Canada. All the automation guys up here use Misumi.by ShadowRam - Reprappers
As a person who has used reed switches in other applications. Do NOT use them as home switches. Replace them. The range is random, and the hysteresis is large.by ShadowRam - General
Misumi is what all the automation guy use, Example - 8mm shaft @ 400mm length - $9.70 Customize any diameter/length. You can pick surface finish, and a whole slew of optionsby ShadowRam - General

So do we boycott Makerbot for putting these in?by ShadowRam - General
What kind of the USB to Serial cable are you using? It looks like RapidBot comes with an FTDI cable. The drivers for it are found here http://makemendel.com/support-1/downloadsby ShadowRam - General

The RAMPS is like a motherboard. It just holds the microcontroller and the stepper motor controls together in a nice neat package, and allows easy hookup of power/etc.by ShadowRam - Reprappers
As this is my first machine, I will be mounting a floating heat-bed above the baseplate and keeping the print size within 12" x 12" x 12" at first. If all goes well, I'll expand it. I'm not expecting it to be the fastest printer in the world. It is larger and has more mass moving around in both X, Y directions. The steppers are larger than the stardard rep-rap, so we'll see where my speed endsby ShadowRam - Reprappers
Hello Everyone, I'm new to the RepRap community. I've recently got my hands on a Cartesian Bot that I've decided to take the plunge and make it into a 3D Printer. It's fairly large compared to the standard RepRap machines I've seen. I'm documenting my progress on a blog I've set up at www.shadowram.ca I sure I'll be on here and the IRC channel asking all sorts of questions. Everything you sby ShadowRam - Reprappers
Curious, I'm new to this whole 3D Printer scene. Why do people use thermistors and not RTD's? RTD's temperature to resistance is at least linear.by ShadowRam - General
