I have a mendel running on a RAMPS board. The machine is shared by a few of us, trading from house to house. I had been running on Repetier, my buddy preferred Pronterface. He loaded up Sprinter firmware, instrument is running fine still, but I noticed that I no longer have control over cooling nozzle fan speed. It is either all on or all off. If you manually send a fan on command, 255 is on

Interested in your design, a few questions
1 In your BOM, you have 9567K314 listed as a Mcmaster Carr part for your Z spring. Can't find that part in Mcmaster. Perhaps 9657K314?
2 Why the spring? I would think that with vibration, you might get small bounces in the z axis. I was puzzling why not build it upside down, the platform resting on the nut, the spring holding it in place in backpr

OK, here is what I believe to be true
Repetier will not run g-code files from the sd card, even sd files from slic3r, only the binary files that repetier creates.
When running binary files from the sd card, if you have to pause your run, you have to pause and resume from the SD card window, not the main program window
If the Repetier program locks up (been having lock up problems with the laptops

Repetier
I am working on a design with some surplus Berg lead screws with a 0.375 lead. (sorry, jumped out of the metric. that would be, what, 9.525 mm?) 200 steps per revolution, gives me a step size of about .048mm? That can't be quite right. I have been going to bounce this off someone in the group, should I start my own topic, or is this an acceptable spot? currently planning on using standard 1

Short answer, still have a problem.
Longer question. I just went to my copy of Slic3r 0.9.1, opened up an stl, sliced it, saved the g-code, copied the file onto the sd card and to the desktop, put the card on the RAMPS, loaded up repetier, opened the file from the sd card, ran it, had the same error. I then loaded the file with repetier, ran the file directly, and the file ran. The sd card, SD

Repetier
OK, have repetier .72 loaded, have the repetier firmware loaded, running on RAMPS 1.4 on arduino mega 2560. Can manually home axis, manually heat up extruder and extrude plastic. have an sd card on the ramps with g code files on it created in slic3r, files ran on pronterface. I can see the files on the sd card tab, when I go to run a file from the card the log says

Repetier
Trying out repetier, trying to get the firmware loaded right. I have Mendel Prusa, running on RAMPS 1.4 on an arduino Mega 2560. Went through the configuration.H file, reset everything that looked appropriate. I can connect, heat up the extruder, manually extrude, manually move X,Y and Z,. I have mechanical endstops, which worked fine when I was running pronterface under sprinter. I tell it

Repetier
I am running RAMPS 1.4 on Arduino mega 2560 on a Prusa, looking at trying out Repetier. So, the first thing I figure I need to do is set up a configuration.h file, translating the numbers from my Sprinter configuration file.
Now, some things are obvious. (RAMPS 1.4 is still 33, 1 is still a 100K thermistor).. I don't know what #include
#include "pins.h" do, I hope I can leave them alone.

Repetier
Yes, I have used Slic3r to separate plates of non connected parts. When you have a single STL which is made up of a group of things, and you just want to print one of them, the split function is invaluable. That is why I thought I would throw it on the wish list

Repetier
sorry, brain dead. I meant Slic3r. Slic3r can split an stl made up of separate items into component parts, and multiply or subtract those component parts. Since Repetier can use Slic3r as the slicing mechanism, and use pull down menus to slice per an established set of criteria, (Nice touch) I thought it would be nice if you could split a STL file like slic3r does from the repetier interface

Repetier
I am just finally getting my machine to repeatably spit plastic, now in to calibration/tune mode. The next thing on my list is to try repetier. (I don't know if the laptop I am running the system off of has the graphics capability.) In reviewing the software I downloaded on my desktop, I did notice one thing. I have been using sprinter and Pronterface, Sprinter has the capability of splitt

Repetier
Ah, I didn't reset or shut down, that could cause it. Thanks.
I have been going to shift over to repetier from pronterface, but I wanted to solve one problem at a time. Do you know if repetier runs off of sprinter? I have seen conflicting reports about that.

Well, I have purchased and connected an SDRAMPS for my system, connected it, and have had no crashes since. I would have liked to have identified the actual root cause of my particular crash scenario, but I needed to be able to print to fine tune my instrument. So, hopefully this will be at least a short term fix. I will go back to the problem later, while I am building my next machine.

Thank you. I will try out the unit when it gets here, just wanted feedback from someone who had used it. Will your program abort a run or allow pauses?

Adding SDRAMPS to my ramps arduino system, running g code from splic3r, currently running off printerface. Once the run is running off of sd card, does info continue to feed back to printerface in computer? Things like percent done, nozzle temp, things of that sort?

No, not solved yet. I have a short term solution, (sdramps), a medium solution(going to try plugging in to a small power conditioner) and I am still looking for a long term solution. I also have another arduino and ramps unit coming, just in case my particular board is succeptible.

Yes, my freezes seem to be random, but there have been those who have attributed it to an outside cause, like the compressor turning on in another room, but on the same power line as my instrument, causing lockup voltage spike. Mostly, I was just suggesting you try a small ups

Is it possible that Printerface itself is too sensitive? I ask, because I have noticed in several cases that Windows Task Manager shows printerface as "Not Responding" and I have to shut down the program to proceed. Although I can close the program by hitting the x in the corner, and usually in a not responding program I have to take other steps to close it out. But if I unplug the USB from the

If you see my "prusa locks up" topic below, below, you know you are not alone. I wonder if a small UPS might be your solution. Or are you asking how to rescue your 3 1/2 hour run, which I would guess would require a text editing of the g- code, and a lot of luck

I had never delt with scad format, so I didn't know what I was looking at when I saw this earlier. An associate at work explained scad, and google led me to a free scad program, which I can then save in a solidworks relatively friendly format, stl or the like

Can anyone point me to where the Prusa i3 printable files are in an STL or parametric, or any other format I could open up in Solidworks?
Thanks

General Mendel Topics
Thank you so much for the input. I am afraid at this point, I am somewhat stuck with the RAMPS system, Believe it or not, the RAMPS system is what we went to because the previous system was so unreliable. I am interested in the details of your system, though, and if you have a minute to share the bare bones of your setup (did you build the wiring interface on top of the uno, or is it all compon

I have tried 3 different USB cables, all of them under 1M
I confirmed the laptop is not going in to hibernation, locking out USB, or any other power saving setting issues
I have tried a total of 7 different USB ports, I haven't tried a powered USB hub yet, don't have one
I just ordered an SDRAMPS unit to attach onto my RAMPS, should have it in a week or so
Good suggestion on bolting the RAMPS to

Dagnabbit. I jinks myself by responding on the forum. My system just froze up again, in the middle of a 2 hour run, (which I had successfully printed out twice in the last week). Still freezing up, even when externally powering the sanguino. Just loses connection, and cannot reestablish the connection. One answer is the sdramps attachment, which will be my next order, but dash it all, why ha

OK, no guarantees, but we have been running for the last 3 days with the arduino board powered by a wall wort 12v power supply, I haven't had any crashes in 8 builds. I haven't tried loading the firmware, to see if that was the root, but it is looking promising for the biggest problem I had. I will let you know if it also solves the firmware loading problem

Thank you, that is good to know. Once I tweek a few other problems I am having (lock-ups and the sort) I am going to simplify my instrument, get rid of external temp control and use the relay. Thanks for the feedback. Did you have to configure Marlin to tell it to output that way?
