I am hoping someone can help me. I am converting a BFB3000 control to RAMPS 1.4 and Marlin. I have been trying to just get the X-Y-Z steppers to work. Here is what I know / tried:
- VMOT - GND = 15V
- Voltage across pins to motor = 0V
- Checked the wiring to each stepper coil - there is resistance across each pair - Look OK
- When I start up, sometimes the steppers momentarily snap to attention and then goes limp again - :(
- Tried disabling the endstops
- Tried jumpering the S to + for the endstops.
- All three of the pin pairs under the steppers are jumpered
- In Simpify3D, I click "enable motors" - RAMPS LCD shows "No Move."
This all makes me think I have Marlin incorrectly configured or I have damaged the RAMPS board somehow. Attached is output from the communications from Simplify with Marlin on start-up. Also attached is a copy of the configuration.h file.
All a little frustrating; this should be the easy part, and I have already spent 2 days :( Thanks in advance to anyone taking the time to respond.
