Hi Plasma, I have built a board with a Trinamic TMC429 and TMC260/TMC262 and controlled it with a Maximite over SPI. In an other project I use the A3982 with a Micromite to drive 3 steppers. Which nema did you want to use? What resolution did you need (half-step, mini-step, micro-step)? Frank |

Not with a mmbasic yet but very often with an arduino. I get the best results with a stepper driverlike the A3982 or especially smooth stepping with the DRV8825. Polulu has great little devices Polulu stepper drivers Microblocks. Build with logic. |

I have no idea what steps i need , but i think Normal and mini is usefull. Can it be mixed ? Ps: thx for the answers |

Hi Plasma, it's independent from your used driver chip! TMC260/TMC262 can half, mini and micro-steps with acceleration ramps. The TMC429 in combination with these chips can handle up to 3 motors inclusive position-switches. The A3982 can only full and half-steps... What would you do with your motor? Frank |

I build a mechanic game with x/y rotating plattform And some sensors for calibration. No real power needed because the plattform have 200 gramm. Only fast and acurate rotating in booth directions. I build this last year with some servos but dislike The inacuracy if you rotate over a long range with Fast steps. I will not use digital servos because i need the Stepper method for a other project ( messsystem) |

For small stepper motors, these drivers seem to work nicely. Wahnsinn cheap, too. Visit Vegipete's *Mite Library for cool programs. |

Hi Plasma, here is the link to my Arcade cabinet what I told you. 
Please send me your mail-address over PM - I will send you my code and circuit next week... Greetings Frank |
