I use 240°C on ABS and have made hobbed bolt by myself and its rough enough I think. What is the optional speed ? I use these parameters in sprinter #define _AXIS_STEP_PER_UNIT {80, 80, 4000, 1100}.by Arnold - Printing
Hello everyone, is it ok when my extruder motor is moving faster than filament goes down ? When I open the press with springs there is the ABS dust so hobbed bolt slide on abs. Is there any calibration I have to do to make extruder motor move synchronize with abs filament ? I just made pronterface test with extruding 100mm and it was ok.by Arnold - Printing
Ok, I installed fan and it really helps, now I am testing it and its ok. After print I remove old mosfet and install new one for assure that it works fine, color of its metal is good indication that something is wrong. thank youby Arnold - RAMPS Electronics
Nope I dont use cooling fan, I run printer really slow so I dont know if is that so important. I can install fan, is it really help ? It worked fine before this day without fan.by Arnold - RAMPS Electronics
Hi all, I have problem I cant solve. Till tomorrow I printed fine, but today when I heated up the heatbed smoke showed from the place of Q3 position. Q3 was melted and broken so I bought the new one a replaced it. But when I turn heat on bed 120°C, the Q3 is becomming from silver color to grey and start overheating. Does anybody know what is the cause ?by Arnold - RAMPS Electronics
Ok, and meaning of led is just that heatbed is powering ?by Arnold - General
I would like to see just simply answer So what is the right work of these leds ? When both light or when one lights. And if one should lights, what is the meaning of second one ? And what is the meaning of leds generally, just that heatbed is powering, no other signal ?by Arnold - General
Hi all, I soldered two leds with opposite polarity and resistor, but when I heat up heatbed only one led lights. Why there are two, what is the functionality difference of these two leds ?by Arnold - General
Guys thank you for advices. Since I am not educated about electricity Iam going to look for something like awg 14 in local shop. Thanksby Arnold - General
Hello, what kind of wire do you use for powering heatbed ? I have common like for example nema17 has, when I turn heater to 110°C the wire is really hot and soft, is it OK ? Or what kind of wire do you recommend ?by Arnold - General
Hi Cameron, thank you for advice. I want to try milling. I know that it is danger, I am going to be carefullby Arnold - General
Hello, does anybody know, how to allow minus direction of Z axis on Arduino with Sprinter ? With direction I mean under endstop.by Arnold - General
What drawing, engraving g-code generating software for reprap ?by Arnold - Printing
Can anyone describe me how to use mendelize.py like postprocess on cad.py gcode file ?by Arnold - RepRap Host
Hi all, I would like to mill but when I open stl file it types - Warning, there was no text output in writeChainTextWithNounMessage in skeinforge. How to open something when even svg I cant open ?by Arnold - Skeinforge
Hi, can anyone advice me some free g-code generating drawing-milling software for W7 64 ?by Arnold - Printing
Hi everyone, I have a question, is it somehow possible force Pronterface to type a message that there was endstop triggered ? Even when I trigger it manually ? I use Sprinter firmware. In default it reacts only at home button and also without message.by Arnold - Printing
It was luck that I pick the first combination, I wanted to give it up The right combination were A1 A2 and B1 B2, on the board A1 B2 A2 B1. Same at other one. I have read many times what you wrote and kept trying till good results. I just wonder that I didnt destroyed the board or motorsby Arnold - Stepper Motors, Servo Motors, DC Motors
Ok, so I put them together and it works perfectly. Thank you very much for your time Noobman, it was very helpful. Thanks.by Arnold - Stepper Motors, Servo Motors, DC Motors
So now I just connect cables on same pins and its done ?by Arnold - Stepper Motors, Servo Motors, DC Motors
Ok so I tested A1 A2 and C1 C2, then I tried changing of positions on pins till I have correct move. Then I did the same with B1 B2 and D1 D2. Both of them, you call it coils I think are moving to the same sides when I test it in Pronterface.by Arnold - Stepper Motors, Servo Motors, DC Motors
So many many testing now I have 2 pairs working (2x 4wires)by Arnold - Stepper Motors, Servo Motors, DC Motors
Ok, I tested second 4 wires and they are not working correctly, the first 4 wires are ok. On the second 4 wires I tested every possible variation, but it turns unpredictable.by Arnold - Stepper Motors, Servo Motors, DC Motors
WOOOW, nice, I tried it, now I have connected 4 wires, one half and it does exactly what it should do in Pronterface, so now how to connect the rest 4 wires ? Should I put the rest with with working combination like first tested one and then just combine wires together ? I mean the same wires on same pins together.by Arnold - Stepper Motors, Servo Motors, DC Motors
Or better to say I have A(2a,2b) and B(2c,2d)by Arnold - Stepper Motors, Servo Motors, DC Motors
Ok, so I used first two pins on stepper driver and tested half pairs of wires. The result it that I have now two groups of pairs which react by shaking from Pronterface. Lets say I have group A(4wires) and group B(4wires), so how continue ?by Arnold - Stepper Motors, Servo Motors, DC Motors
Ok, no result I am at the same and really dunno what exactly Iam doing now, my maximum was to make motor shaking not more. Isnt there any manual how to make it work step by step ?by Arnold - Stepper Motors, Servo Motors, DC Motors
Ok, thank you, I will make some try then I will tell result. I dont have datasheet and no brand sign on motors.by Arnold - Stepper Motors, Servo Motors, DC Motors
Hi NoobMan, you mean like that ? : if I have Pairs A1 A2 B1 B2 C1 C2 D1 D2 to make: 1wire / 2wire / 3wire / 4wire / A1 B1 / A2 C2 / C1 D1 / B2 D2 / ?by Arnold - Stepper Motors, Servo Motors, DC Motors
Hi everyone, I am totally newbie in electronics so I would apprecite some help from experienced ones. I connected my stepper motors nema17, two of them to Ramps 1.4 board. Uploaded Sprinter to Arduino board and then turned on Pronterface. When I click on 0,1 step, motor is just whistle, on 1 step it turns only once per two clicks (sometimes), on 10 it turns but randomly, sometimes left, sometimesby Arnold - Stepper Motors, Servo Motors, DC Motors
