I really cant afford anymore, so please help ! I bought a printrboard rev D preloaded with marlin firmware and it worked and was moving motors.

some problems calibrating - 13 years ago

having a really really hard time figuring out how to calibrate a printrboard running marlin on mac. I recently became aware of a methond using ponterface//Gcode : •connect with Pronterface •type M501 in the lower right corner and hit SEND. It will output a block of information. •recalculate your M92 settings per that guide. •save all your M92 settings with an M500 command Im having a problem

z axis shakes ALOT - 13 years ago

Hi I finally got my reprap up, z axis shakes back and forth like crazy... I put a rubber band, but it didnt help :-/ Oh... I have 1 motor facing one way, and the other facing the other way. Prusa iteration 1 with iteration 2 couplers. What should I do? I heard something about decreasing the speed the motors go ? I dont see why it should matter that the motors are facing opposite directions as

Re: trying to repair sanguinololu need help - 13 years ago

wasnt testing with the usb actually plugged in Thanks so much for your response ! what do you mean vias? If I run a cable to the regulator VIN pin, and disconnect the pin from its track... that might help right? and if that fixes it I could create a new track. Same for the ground if its really broken. hmm. I would try this... but thats the thing, in my original post question number 1, it s

trying to repair sanguinololu need help - 13 years ago

I took out the 7805 - > ic1 because i thought i might have fried it. The board powers on when there is usb but not when there is only 12 volts from screw terminals. I then plugged in the board and did some tests... 1) from the 5v out pin and the ground pin im getting 0.5V (by pin, i mean pin slot, as in where the 7805 would actually go into the board, im just going to call it pin.) This is

Re: Please help - 13 years ago

Alot of research... And I figured an idea to check if problem is pololus or sanguino output. I study'd the pololu datasheet and saw enable, step, reset, dir, sleep pins, as well as ms1, ms2, ms3. I also think "enable" has to be low and reset should be low. anyone know what ms1, ms2, ms3 are supposed to be ? Are the pololus on full, half, quarter, eigth or 16th step? Also what should direction

Re: Please help - 13 years ago

anyone know how I can test the pins if I desolder the pololus ? If I desolder them and then send code to have them move, what should the pins output and how can I test that its working ?

Re: Please help - 13 years ago

In your image, the pololus look a bit opposite of mine... but my board is a bit different then yours. I bought mine in some sanguino kit. They sent me a pic of how they said its supposed to be and I copyed it... here is mine : and here is the one they told me it should look like when I was done adding the pololu's : thanks again for your help. So Based on their picture id say it was right..

Re: Please help - 13 years ago

Eh it just says OK when i enter those commands on cool Term. Im using a ATX power supply 400 watts which I converted to give a 12 volt dc output by following some guide online. I HOPE I have pololus installed correctly... the current pot is facing the board not the motor pins... closer to the side with the usb input... Thanks for your help

Please help - 13 years ago

hi, im pretty newb. Ive been trying to connect a motor to sanguino to make it move as a test, but I cant get it to work. I know I have the correct serial port because if I type the Gcode M115 it returns the firmware sprinter and version ect. But when I try to connect the motor to any of the motor connections it never moves it. Also when I unplug it from computer the board stays on so I know the

problem mounting extruder - 13 years ago

Im trying to install a wades extruder.. but the gear seems to be touching the x carriage. What am I missing ? I could put a couple washers... but it kind of also touches the brackets that hold the timing belt down. if I turn the wade the other way, then the motor kind of hits the timing belt.

Re: cooling fan for pla - 13 years ago

thermal break on a j-head, that would be the part where it extrudes I guess ? Why does disturbing the air make a better print ? I guess 1 fan that hits both would be fine ? Also... im confused, because if you want to cool the pla with a fan, then why would you use a heated bed ? Yeah... confuse.

cooling fan for pla - 13 years ago

Hi. How serious does the pla fan need to be ? Will a small 5v pc fan be enough, or do I need something powerfull ? Also, do I just need to point it at the extruder ? or does it need to be pointing down directly at the print bed ?

Re: making connections to sanguinololu - 13 years ago

thanks for your response. not clear to me what you mean though. I put crimps on the wires coming from thermistor/resistor, then I put those crimped wires into the housings. so the question is how do I get the housings to stay attached to the sanguinololu pins.. do I have to put more crimps on the sangui pins ? (because the housings fall off of the pins) also thanks for that, I only have to use

making connections to sanguinololu - 13 years ago

Hi. I have a sanguinololu and I have some questions about making connections to it. How do you actually connect to it ? I have some 2 and 4 pin moled housing, but they dont actually stay on they just fall right off so I think im missing something. How do I make the molex housing stay connected to the sanguinololu ? (if im even supposed to connect it with molex housing) the other question is I ha

Re: leveling print top plate - 13 years ago

How do i properly pretension them, because all the build wiki really says is screw a nut 1mm on after spring, so to me its not really clear since slight touch makes it not level. Also about prusa iteration 2, where can i see a good build instruction so i can see how top plate has no springs? Bc its still iteration 1 instructions on wiki... they changed it all when i was halfway threw iteration 1
