Hi, after your help my torque problems improved. I think I have enough torque for now, but I'm facing another problem:
I need to improvise rudimentary control of a small DC motor. What I want: Set speed and direction of the motor from G-Code. I don't need encoder feedback, it would be nice, but I could live with a simple PWM signal (24V, > 1A max.), if I can set polarity and pulse width from G-Code. Hre's what I have: DC Geared Motor 24V, <1A, 1000 CPR encoder, very low load; Spare Mesa 7i39 channel Is there any change I could utilise this unused BLDC driver to power my DC motor? Like use one Phase against ground and set the PWM rate of this phase somehow? Spare channels on a Mesa 7I42 breakout board Can I create the signals to control a H-bridge on four pins? Or at least a direction and PWM signal for a intelligent H-Bridge driver on two of the pins? I sure have a bunch of MOFETs to build a driver stage but probably not a 'intelligent' driver. So, what would you do? Any other idea? Thanks for you comments Flo ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
