Bipolar parallel will give the best results seeing maximum torque is more important here than higher speed. Here's a short explanation as to the difference in the various ways to connect 8 wire steppers. |

Jason, You may also find it useful to read the Stepper Motor Basics paper from Mariss & Marcus of Geckodrive - either online or downloadable as a pdf Dave |

Don't worry about wire polarity. If you swap one set the motor will run the other way, swap both and nothing changes... (The software can swap the direction of motor rotation anyway in the setup.) |

Thank you for the links tumutbound and DMIOM :thumbup: interesting read Kwackers I thought it might be a case of wire the motor up and if it doesn't work if swap some wires But I just wanted to make sure :thumbup: |

"According to the company that sell the toner kit they claim that only GBC laminators work because they have heated rollers Apparently other laminators heat between the rollers and don't work " Bit like a fuser in a photocopier. Cant remember what temps we are talking about in a copier tho. Heat created by long lamps that ran thru the centre of the rollers. Springs to set the tension between the heat rollers if memory serves me correctly. |
