Hello! I have been unable tu play with my Reprap for a while but now I am starting back! I tought that everything was finaly done (configuration, calibration) and when I finally pressed "Print", I got this error: Print started at: 19:48:45 Failed to inhibit sleep: Traceback (most recent call last): File "/home/martino/workspace/RepRap/Printrun-master/printrun/pronsole.py", line 1426, in staby Atfer - RepRap Host
Hello! I recently builded myself a Mendel (Not prusa) but I am now realizing that I don't have much time to play with it. It sadden me, but I fear that it will just finish as a decorative piece in my house. It is from the latest 3D Reprap technology and the composend such as the extruder are of great quality. The specs are : -Original Mendel -J-Head MK4-Extruder -RAMPS 1.4 -Heated bed MK II -Pieby Atfer - For Sale
Thanks for your answer, but I've already checked if it was slipping, but that's not the problem. I've spent some time adjusting everything in SFACT and the flow rate is no perfect but good. The problem really is that from the second layer, it start extruding verry slowly. I tryed and made a new installation of SFACT and only modified these parameter : 1- The filament diameter to 1.6 (I use 1,75by Atfer - General
SFACT generate my gcode and then I load it in Pronterface. And I know that there is an option in the raft tab to adjust the flow/feed rate for the first layer and that the main an perimeter feed/flow rate are adjusted in the speed option. Every feed/flow rate have the same value : 15 for the feed rate and 1 (scaler) for the flow. There is probably another option that I don't understand or haven'by Atfer - General
Hello! I switched from Skeinforge to SFACT recently and I am getting a much better print quality! The only problem is that it won't go further than the first layer... It doesn't stop, but the extruder start extruding reaaalllllyyyy slow from the second layer to the end. Looks to me like the flow rate drop from the first layer to the other, but I really can't find in SFACT where I could adjust thby Atfer - General
Hello! I made my first prints with my Mendel, but noticed that my hot end wasn't the best. The nozzle is 0,32mm and has a round shape and the brass barrel (for 1,75mm filaments) is screwed in a PTFE rod. The major probem is that I can't stop it from oozing from the top of the nozzle and that it tend to drag line because of its round shape. And since I want to achieve the best quality of printingby Atfer - Reprappers
So the flow rate value always match the feed rate value?? Thanks for your answer!by Atfer - General
Hello! I finished my Mendel build and made my first print! The quality is crappy but they look like something! Now I tuned skeinforge like I could but I have a hard time to choose what feed rate and flow rate I should use. Could you tell me if there is a ''standard value''? Or if someone with the same equipment could tell me what is the value he/she use, I would appreciate it! Right now, my settiby Atfer - General
Ok, thanks for your help, but I found that my problem was a stupid short in my connecter between the bed and the ramps. Yesterday I read 1.5 ohm on the bed, but I got 0,4 today. Now everything is almost finished!by Atfer - General
It is 17, I think this should be enough. And while making my test, the block heater is not working.by Atfer - General

This is what it was looking for! Thank you! I'll try it and try not to kill the other pins this time. EDIT : It worked! I've been looking for the pin assignment in the firmware but couldn't find it. I looked in the thermistor table, but didn't notices the pins tab (working on a Eeepc is harder than expected).by Atfer - Reprappers
I've been looking over the forum about how to use the second extruder with the RAMPS1.4, but I don't find any documentation. If it is possible, I could just switch everything in the second extruder. But if it is too complicated and could result in issue, I'll just buy a new arduino. Thanks for your help!by Atfer - Reprappers
Thanks for your answer, I've looked for the resistance : The working pin shows a resistance of 696 ohm, the broken one shows 152 ohm. It is lower, but it's not 0. I don't know if it is possible to compensate with the firmware? If not I guess I'll have to order and wait for a new arduino.by Atfer - Reprappers

I see how that could be a problem... So is there a way to change the input,by Atfer - Reprappers
Ok, I found that the problem come from the arduino itself. I tried to export the firmware again, but it didn't change a thing. I don't understand how is that possible. It was working like a charm and then not. Is there a way to test if everything is alright with it? One solution I could see is to use the second extruder thermistor input, but I didn't find what to change on the firmware to changby Atfer - Reprappers
No, because when I plug it in the bed input, it is working, so the resistor is not the problem, it come from the board.by Atfer - Reprappers
Hello again! I just got this strange problem that appeared suddenly : My thermistor temperature is at 275°C and won't change. If I connect my thermistor to my heated bed input, it shows the good temperature. I tested with my voltmeter the two pin of the extruder thermistor on my ramps1.4, and I can see that current goes trough these, I don't that with the other thermistor input. Is that softwareby Atfer - Reprappers
Hello! I just finished my reprap and everyting seem to be working fine! After I tested that everything was ok and that the extruder was extruding properly, I tried my first print. Just before it start printing, the extruder went in reverse mode for about 3-5 second and expulsed the filament from the extruder from the top. Then the extruder stepper went the good way, but without the filament.... iby Atfer - Reprappers
It worked!!! I change from monostrand to multi stranded wire and it preheat to 230 in 2-3 min!by Atfer - Reprappers
I'll post a photo soon enough, but my block heater isn't even on the extruder, I make my test with it hanging on its wires. But maybe there is worth mentioning : The wire that is soldered on my resistor is a nichrome wire, monostranded (is that a word?) When I start the heat, the wire become really hot, and not because of the temperature of the resistor. Maybe one strand of wire isn't enough forby Atfer - Reprappers
I coated the resistor with the fire cement to make sure that it has a good contact with the heat block. I've tried before with aluminum foil, but didn't change a thing. And no, I don't have a fan. 100K thermistor is selected in the firmware. I just tried to connect the resistor to both extruder power output, and it doesn't change a thing. I'll try to cover it with several layer of Kapton tape.by Atfer - Reprappers
Soooo I just wasted 12$ on a bucket of fire cement... My extruder can't get passed 209C. My power supply is 17A and should be sufficient, but I just can't reach the temperature. Is there a way to increase the current in the resistance? Like connecting it to both extruder power output instead of just one? Thanks for your help, I need it!by Atfer - Reprappers
Hey! What about CPU thermal paste? Would that be a good idea or is it too liquid?by Atfer - Reprappers

My insulation is all amde with kapton tape. Thanks for the aluminium foil idea! I'll try it right away!by Atfer - Reprappers
Finally, I can't get past 178°C. I use this block heater : . What I think can cause this problem is that my resistance is not ''fixed'' in with epoxy or fire cement, but is just inserted in with a layer of Kapton tape around it to make it fit properly...by Atfer - Reprappers
Hello! I would like to know how long does it take your extruder to reach its temperature? Maybe I need more insulation, because it take my extruder about 1hr to reach its temps (230°C for ABS). Or is it normal? Thanks!by Atfer - Reprappers
Well, that certainly seemed to help!by Atfer - Reprappers
Hello! With Skeinforge, I can make my extruder extrude, but when I press print, everything is moving except the extruder. My gcode is from Skeinforge, but even with pronterface itself I get this error. Any idea? Is there a place where I can select my extruder? (Since RAMPS1.4 can have two extruder) Once again, thanks!by Atfer - Reprappers
