This is just because the servo driver has quad encoder inputs and stepper motor drivers do not. I'm a retired EE and can get the quad encoder inputs into the...

... You can actually close the loop between the driver and motor and leave the controller out. Closing the loop on a stepping motor is harder then on a servo...

... It's simply going to be a stepping motor driver with a rotary encoder for the motor. So you connect the driver to a breakout board as you would with a...
Hi It's unlikey there'll be any software changes to TurboCNC, there has not been for the last ?? 6 years or so. You'd be better off implementing an external...
... Mach 3 doesn't need to know about it. this is (and should be) a hardware solution. the hardware driver is told to make 10000 steps. it keeps track of...
Otherwise, if you're going to go this much trouble on a stepper, rather just built a DC motor servo drive, using your encoder. No more lost steps, faster.... ...
I have just replaced the Z-axis lead screw nut with one that has more friction and a whole lot less play than the original one. Now, when I first press the...
Hi Bob, At first glance it seems that the start-up torque on your new Z-axis is a lot higher than the old one. The sound you are hearing may be the stepper...
Thanks folks. I finally got a chance to tweak my system a little this afternoon and it has helped with the grinding noise as you suggested. It appears that...
Hi Bob, You say the best resolution you can get is +/- 0.0625. For my system that would be a lot and would be unacceptable. However, I don't know your system...

Frankly, you do not want to mess with closed loop methods when using stepper motor drives. Rather upgrade to DC brushed or brushless. If you are having...
