i tryed switching the wires out for 3 instead of two, it didnt work but the LED still lit. I only have two uncut 3 wire cables left so i attached them to the x and y endstops and tryed to test them, would not connecting the z endstop effect the result. and if I have a 4 wire extension would cutting one wire from that be the same as a 3 wire? m119 has changed to >>>m119 SENDING:M119 x_mby Basicblacklabel.com - General Mendel Topics
the kit is from makergeeks.com, facing the front of the printer the x endstop is on the right, the y is closest to the front and the z is on the left closest to the bed. im using the geeetech.com mechanical endstop v1.2, the one with the PCB and LED. I used to install my endstops. It says to use a 3 wire cable and cut one wire. My LED does light up when depressed but m119 reports no change. SENby Basicblacklabel.com - General Mendel Topics
I installed the jumpers, the microstepping is now working but the endstops still do not register (the led's do light up but motors continue) and the motors still do not move in the negative direction.by Basicblacklabel.com - General Mendel Topics
alright thank you, turns out they did come with my kit I just never knew what to do with them. ill install them now and post the result. are jumpers sensitive to polarity?by Basicblacklabel.com - General Mendel Topics
how do i install jumpers, i cant find anything on themby Basicblacklabel.com - General Mendel Topics
I was able to get all endstops to know when they where being depressed but all of them were saying the opposite of what they were so I inverted endstops in sprinter firmware and they register what they should now. however my motors are not moving in a negative direction now. this seems to be an endless cycle of problems.by Basicblacklabel.com - General Mendel Topics
no i have no jumpers connected, what is the purpose of jumpers, I didnt come across them on any of my assembly manuals. I first sent m119 as a baseline and then I press the z endstops in. here is the result. SENDING:M119 x_min:H y_min:L z_min:H >>>m119 SENDING:M119 x_min:H y_min:L z_min:L it seems like this is backwards since it originally started at home and when depressed showedby Basicblacklabel.com - General Mendel Topics
I tryed everything you said but nothing seems to be working. m119 is stlll the same so I tryed using g92 and that didnt work either. I tryed to do a test print and it begun to print on the top right hannd corner of the be but the z axis was about 2 inch above the bed and the extruder just spewed out plastic from there.by Basicblacklabel.com - General Mendel Topics
I had the same problem with my x and y axis, I tryed a million things to fix it so im not sure what actually did the trick. Im pretty sure it was after I tightened my belts and recalculated my steps per unit using the calculator on mendelmax.com. here is the link i would give that a shot.by Basicblacklabel.com - General Mendel Topics
>>>m119 SENDING:M119 x_min:H y_min:H z_min:H my z motors are also still not working, i have the max feedrate for Z set to 1 mm/sec and the pots are set to .7v the motors make noise and vibrate but nothing moves. I have tryed multiple different steps per units.by Basicblacklabel.com - General Mendel Topics
UPDATE: axises are now moving in negative direction, I am so close to fixing all my problems can someone please help me figure out why the board always thinks the endstops are triggeredby Basicblacklabel.com - General Mendel Topics
I just found an online calculator to adjust my steps per unit. it turns out that my SPU is 3.74 instead of the 80 i had set. my axises are now moving normally in the positive direction. I now need to figure out how to get them to move in the negative direction which I think has something to do with the endstops. and i need to figure out why the m119 command always says that the axises are home. tby Basicblacklabel.com - General Mendel Topics
I just used to the m119 command to check the status of my endstops, no matter where the axises start or end it always registers as home, why is this?by Basicblacklabel.com - General Mendel Topics
here is a detailed picture of my board, i marked where everything is. and i included the diagram i used to hook everything up. The power to my bed and extruder seem to be the only thing that are working consistently. I also measured out the maximum travel distance for the x axis and included that in my configuration but so far my motors are still only moving one step at a time.by Basicblacklabel.com - General Mendel Topics

here is my sprinter arduino sketchby Basicblacklabel.com - General Mendel Topics
here are the pictures of my mendel and ramps 1.4, notice the bed isnt centered in the frame. is this a problem? I will upload my sprinter sketch in a few minutes becuase it is on another computer. thanks to any that offer helpby Basicblacklabel.com - General Mendel Topics
Hi, I have just finished building and wiring my first mendel i2. I moved on to commissioning but encountered multiple problems. keep in mind I am a complete noob. First of all I upload sprinter and connected my printer to my mac using pronterface. The printer connects fine. when I try to move the motors they each move one step at a time no matter if I press 1,10, or 100. None of the motors moveby Basicblacklabel.com - General Mendel Topics
