I found that if I pause the printer I can change the hot end and bed temperature from pronterface. Then I resume printing and it's done.by epareja - Reprappers
I had to raise hot end temperature for the ABS to flow easier but I will have to continue working on this because in 100mm it actually extruded 80mm. Thank you!by epareja - General
Hello, I build my prusa v2 with this Hot End. I calibrated the extruder motor in my Marlin and RAMPS electronics to move the filament exactly 100mm when I ordered so. I did that calibration test without the hotend installed. I would like to know if I have to do that test with the hot end installed? The thing is that if I use Skeinforge 41 for slicing the part the extruder goes very fast and eby epareja - General
I have RAMPS 1.4 and pololu stepper drivers and I had the same problem in the Y motor. I interchanged the X and Y motors and the problem was now on the X motor so I isolated the problem in the electronics, not the motors or mechanics. I don't know Gen6 electronics but pololu drivers have a potentiometer to calibrate the maximum current allowed and I had configured that setting too low. I increaby epareja - Reprappers
Hello, yesterday I gave up with repetier host software although I think it's a very good interface. It hanged up when printing every time. I installed the lattest Marlin and Pronterface and they are working good on dry jobs. I havent installed the hotend yet. I will do it tonight. Thank you!by epareja - Reprappers
Hi NewPerfection, I have the baudrate set to 250.000. I've read that this should be more jitter free than 115.200 but I will give it a try tonight. For slicing do you use Slic3r or Skeinforge?by epareja - Reprappers
Hello, I would like to know what is the best firmware for my RAMPS board. I instaled succesfully the Repetier firmware and the Host and at first it worked fine, but after printing4 or 5 minutes it stucked in RESENDING xxxxx where xxxxx is the line. To correct that I have to reset the RAMPS and restart the host. I like the functionalities of this Repetier software but I would like to hear yourby epareja - Reprappers
Hello, Yesterday night I could detect my problem. It was the 3 faulty endstops. I tested them before installing them to the holders with super glue and it seemed that the mechanical action was not affected. Only the contact. One of them had both NC and NO not working and the other 2 had the only faulty the NC contact. I tested with the jumper and it worked ok. Thank you Repetier!!!!by epareja - General
Thank you!!!! I'm connecting them as in this picture (Endstops Picture). I will try the jumper but I'm pretty sure that the microswiches are working ok when activated because I test it with the multimeter. Is the pullup voltage level available on the signal pin? I've done internal pullups with Microchip PICS before, but this is my frist time with arduino (atmega processors). If I place my testeby epareja - General
Hello, Yesterday I tested my Ramps with the Repetier firmware and almost everything is working as expected (heatbed, extruder hot end). The only thing that didn't work was the endstops. Iwhen I send a M119 i get all endstop values in H state when ythey are not activated but they read the same when activated. Phisicaly they are connected in the normally closed contact (NC).

That was it. My tester leads mark 0.8 ohms so the bed resistance would be approximatlely 1 ohm.by epareja - Reprappers
Thank you!!!! That helps a lot!by epareja - Reprappers
Hello, I've read a lot about hotbed connections and found different solitions for that that including using ribon cable in parallel. I would like to use a single multifilament wire from the MK2 to the RAMPS circuit and found that for 11Amps it should be a 10AWG that is very thick. I also want to know if my MK2 bed resistance of 1.8 ohms is correct. For 12V I will have 6.7 Amps and I'm not sureby epareja - Reprappers
I ordered my printer kit from them and it arrived on time. The only thing is that they did't include the kapton tape and the hotbed thermistor in the kit. They sent me those things with no shipping charges. They gave me a canadian post tracking number that I could track on the USA with USPS. Hope your machine finally arrives.by epareja - General
Misan, did you use Hotbed for ABS printing in that picture? For everyone: I found this 10cm wide Kapton tape on Ebay (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120902838826). Is this good or I'd better go for a 15cm wide one or maybe a shorter tape?by epareja - General
What type of silicone? The white one that is used for transistors and electronics? Yust to be clear because I'm not from USA: alfoil = aluminuim foil? Thank youby epareja - General
I found the problem origin here! The X smooth rod for V2 should be 405mm and not 420mm as the original. It should be better documented in the "How to build prusa Mendel"by epareja - Reprappers
Hello all, This is my first reprap and I bought the plastic parts for prusa iteration 2. The problem I'm facing here is that the size of the x axis is bigger than the vertical rods distance. The distance between the vertical linear bearings of the X end motor and X end idler is 413mm and the distance of the vertical smooth rods is 390mm. I'm uploading a video showing this problem. it will be aby epareja - Reprappers
Thank you Nophead. Where do you buy the glass rope glue from? Good tip you gave me with the aluminium foil. About the other post of the heat bed with tape for ABS, what is the name of the blue tape that is usually seen on youtube videos? Best regardsby epareja - General

Hello again! I have an aluminium heat block that can fit 2 power resistors, but the holes are a little bigger than the resistors so I will have air gaps between the block and resistor.

Hello all, and thank you for your comments. Yesterday I bought 2 part epoxy that said works with hard plastics and it worked. I just wanted to ask Nophead if the solvent cement is used for PVC pipes. banthafodder7400, very good blog you have!
