I grabbed some motors from an old EPSON dot matrix printer. I think it should be stepper motor. anybody has done anything with such motor? how can i use them? anybody has spec on the motor used in EPSON? i see no label on them
I`ve already determine the middle-wire with my multimeter and now I want to know the correct current and amperage of the stepper. How can I find that out? I didn`t find any information or datasheet in the i-net. Somewhere I`ve read that it is a 4 Watt motor.If your OLD laser printers are still available, probably you could find out
hi i'm sorry that i didn't work with stepper before , it's out of field :( i've slavaged a stepper motor with it's driver chip from an epson printer too for testing but didn't have enough time for that . may be later and one more thing i'd like to let u know .. i think u are posting in the wrong section . most of the (...)
I have a stepper motor salvaged from a printer. I can see that it draws 1.3A/ph. I also salvaged SI 7300 chips from it. I am trying to drive the motor with that chip, but fail to do so... I dunno y. The power supply to the chip was 12V 3A. I want to know wheter this didnt work coz of this low voltage! I am sure that (...)
Hello! I am thinking this problem exist because the printer port is closed on default How it is open? I don't know !
I am using ULN2003 to run Mitsumi M35SP-9 stepper motor salvage from old injket printer. The motor is 5 wire unipolar, with 24 V and 7.5 Deg step. so it's 48 steps per revolution. The problem is than I operate it on 12 V instead of 24 V and instead of 48 step it rotates full turn at 12 steps. I havn't check it on 24 V. (...)
I don't think you will be able to find any datasheet, this is probably from an oki printer and sometimes these are custom made for the printer company. Alex
Hello.. I need code for L297/L298 stepper motor driver. I am doing project on thermal printer interface with MSP430. As initial stage, trying to run stepper motor of the printer using the driver circuit. As i am using MSP430 microcontroller, i think i'm in need of code. I will rig up the (...)
Hello Saad, Mach3 is pretty straight on LPT. I would suggest you to please go through following steps to resolve your LPT issue. 1. Are you sure that your LPT port is in working condition. You may connect an external LPT printer to quickly test your LPT port. 2. Are you sure that you are looking at the right pin at LPT port? please see following p
