3 hours ago Hi Don't know if you have used stepper motors before. First principals. They only move when the four motor inputs are sequenced in the right order. No power on any line, motor can be turned by hand easily. Any power flowing into a coil pair will make motor hard to turn, condition locked. Connected up to the controller with enable/ direction lines connected but not clock pulse input. Manually pull that line down intermittently, just tap down to 0volt. Motor should take jerky steps. That will establish that the step signals are activating motor. Connect back up the clock signal line and try the same test with the clock line disconnected where it comes out of the DSP board. If the motor moves, then the DSP is not generating the clock signals in response to the encoder movement.
These are very rudimentary tests without the use of test instruments. The very simplest test equipment that you can use is a lamp connected to two leads. Could be an led with a series resistor. Say 470 ohms. It will give indications of the state of the signal lines, 5volt or 24volt, plus the signal polarity, the led is a diode, conducts. Lights only in one direction. Hope this helps a little, baby steps.

Hello Everyone. I'm working on my first build and using Clough42 kit with version 1.4.0. I have no issues on the RPM detection side nor ton the user interface.
For motor I chose a NEMA23 closed loop stepper with a CL57T v4 controller. I have the controller fed by a 24v power supply and the controller has a switch that can be set to 24v signal level or 5v; I'm set to 5v.
I have no movement of my stepper from the ELS. To verify I used a 5V jumper on the controller PUL+/PUL- and the motor turns just fine. When the power supply is unplugged I can turn the motor shaft by hand but with power supply active is it tight.
Wiring for Pulse, Enable, Direction is as per James' diagram; very straightforward. One difference from James' wiring is that this controller has pins ALM, BRK, and COM-. I connected Clough42 FLT+ to ALM and FLT- to COM-. I have also tested this with those lined disconnected as well as jumpered. I also tested with "#define USE_ALARM_PIN" commented out. No success
I have tried this with the enable pin inversion active in code and commented out. No success.
I started with the TI board ungrounded, but also tested with a GND pin from the TI board pulled back to V- on my power supply. No success.
I have verified continuity from screw to screw on both ends of the terminal connectors.
Some pics of my bench setup are HERE https://photos.app.goo.gl/nZuZtmV9Vi8HL9kT7.
If anyone with experience with this controller can chime in that would be great; or any other troubleshooting guidance for that matter.
Thanks in advance, Mike
