Re: Idea for full color FFF/FDM printing? - 12 years ago
Quotedrumguy560 It seems like the most difficult part would be to figure out how to get an inkjet to work putting out a single jet of ink. Most in modern printers put out a few lines of ink at a time to speed up printing. You could give the ink magnetic properties and make it flow through a electro magnetic field?by tyscof - Developers
Re: Motor torque - 12 years ago
QuoteThe "axis step per mm" does not affect torque in any way. This setting only determines the length of the move. If you set it to 10, it will move some distance, if you set it to 20 it will move double that distance, if you set it to 30 then it will move 3 times the initial distance, etc. Ofc if you set it to 0.1 then you will have to click it 100 times to move that same initial distance becauby tyscof - Stepper Motors, Servo Motors, DC Motors
Re: Motor torque - 12 years ago
Hello it looks like some of what I said was not very clear, When I was adjusting the pot on the driver chip I had to put it all the way to around maximum power around 1.2v vref to get the shaft to turn but even when I put it all the way up the motor still had no torque so I can't go any higher with the pot. I was saying this is weird because the motor has a lot of torque when it is not rotating bby tyscof - Stepper Motors, Servo Motors, DC Motors
Motor torque - 12 years ago
So I have been building a reprap and have been having problems with the motors and think I have isolated my problem. I decided to start my motors fresh so I set the firmware over and set the vref to around .5v. I took the belt off of my x stepper and connected it to my extruder driver(so I could get constant movement and adjust the pot). I set it to extrude for 100 and the motor didn't move. So Iby tyscof - Stepper Motors, Servo Motors, DC Motors

Yea, I set them to around .5 and tried setting it higher with no changeby tyscof - Controllers

Could the drivers be bad? Is there some way to test to make sure they work alright?by tyscof - Controllers

Steppers not have enough juice? - 12 years ago
Ok so I am working on my reprap but I have invariably ran into the problem of my stepper motors making noise and not turning. They make a high pitch noise but don't seem to have enough torque or something to move. If I hit .1 it may move but if I hit anything higher it just makes noise. The vref is set right, In fact I set them higher to see if it would help to no avail. One thing I have noticedby tyscof - Reprappers

Have you found an answer to your problem yet? My steppers are doing the same thing and can not figure out what to do.by tyscof - General
Re: Motors wont turn same old same old - 12 years ago
Do you mean this: #define _ACCELERATION 1000 // Axis Normal acceleration mm/s^2 and this: #define MINIMUM_PLANNER_SPEED 0.05 // (mm/sec) what should I set them too?by tyscof - Stepper Motors, Servo Motors, DC Motors
Re: Motors wont turn same old same old - 12 years ago
Ok so If I set my #define _AXIS_STEP_PER_UNIT higher like to 100 the smaller step like.1 works fine but when I try to hit 1 it just makes a high pitch noise and doesn't move. I set it to 100 because when I set it to 50 it took two hit of .1 to get it to jog once, but say if I try to jog 100 the y doesn't move it just makes a loud high pitch noise, know any cause of this? Likewise if I set it loweby tyscof - Stepper Motors, Servo Motors, DC Motors
Re: Motors wont turn same old same old - 12 years ago
Yep, I set them to around .5 which is right for my drivers, It seems like the y stepper is working great still having trouble with the x now it doesnt want to move again even with the #define _AXIS_STEP_PER_UNIT {10, 30, 3200/1.25,700} set super low. And if I tell it to move now I can just push it without very much effort even if the vref is set really high, so I think I may have burned it outby tyscof - Stepper Motors, Servo Motors, DC Motors
Re: Motors wont turn same old same old - 12 years ago
OK so we have movement! I change this value which I think is what I was supposed to, it was this #define _AXIS_STEP_PER_UNIT {80, 80, 3200/1.25,700 and I changed it to this }#define _AXIS_STEP_PER_UNIT {10, 80, 3200/1.25,700} I went on a online calculator and it said to make it 80 but I found the lower I set it it would move so I just set it to 10 and found that it started moving, the questioby tyscof - Stepper Motors, Servo Motors, DC Motors
Re: Motors wont turn same old same old - 12 years ago
Ok the motors not moving in reverse makes sense now since they are not homed, and No I havent messed around with the steps per mm, in the firmware right? I could see how that would throw off accurate movement but shouldn't the motor still move just the wrong distance? Like if I jog the motor 100 units or connect it to the extrusion driver it should move just not say the exact 100 units right? Orby tyscof - Stepper Motors, Servo Motors, DC Motors
Re: Motors wont turn same old same old - 12 years ago
Okay so then I do have my motors wired correctly, I have them as pins order 1,3,4,6. I have the two wires for a coil on one side and two wires for the other coil on the other side. I checked the voltage the motor was getting to make sure and when I put my meter over the two leftmost wires(B+ and B- or wires 1 and 3) and got a voltage of 12.8 and the same when I put it over the other two wires.

Re: Motors wont turn same old same old - 12 years ago
I don't have a datasheet since I bought them off of ebay but here is the link to the motor, Ill ask him for a datasheet.by tyscof - Stepper Motors, Servo Motors, DC Motors
Re: Motors wont turn same old same old - 12 years ago
When I wired my motors I checked to see what what two wires had the most resistance on them and cut the center tap, on the motors the wires are all blue except for the two center taps which are orange, so i cut those off. I then put the two wires next too each other in a 4 prong connector. I wired it so that the outer wire on the motor connector is the outer wire on the 4 pin connector. PIN1= B-by tyscof - Stepper Motors, Servo Motors, DC Motors
Re: Motors wont turn same old same old - 12 years ago
Well I just tried disabling endstops in the firmware i'm not sure if that would have fixed the problem but I tried it and it didnt seem to make any difference. I also tried manually switching the endstops as well but no dice. I kept hitting the jog and every once in awhile it would move one step so I thought that was weird. I tried changing the voltage to see if a higher value would change anythiby tyscof - Stepper Motors, Servo Motors, DC Motors
Re: Motors wont turn same old same old - 12 years ago
I was playing around with the motors and found something weird. If I tell the x motor to jump backwards or reverse it wont go that way and if I hit the x forward after that it doesnt move it stays in the same place but the x value coordinate goes up, If I go past this value in the postive direction so say I told it to jump right twice then it will try to jump but again will not turn unless I assiby tyscof - Stepper Motors, Servo Motors, DC Motors

Ok so I have been working on building a 3d printer for the past few weeks, I have finally finished off all of the hardware and am working on getting the electronics to work correctly... like getting the motors to move. So here is my problem I hook my x axis motor into its driver and tell it to jump a little but it doesnt move at all (I took the belt off so there is no resistance on the shaft, andby tyscof - Stepper Motors, Servo Motors, DC Motors
