Hello everyone,
I am building my first 3d printer for hobby purpose.
I am currently still in the testing phase.
As setup I have the following:
- power supply 12v 30 amp
- Arduino mega
- Ramps 1.4
- Stepsticks DRV8825
- Nema 17 engines
- marlin 2.0 firmware
- Pro interface (software)
- slic3r (software)
I have connected everything as can be found on various websites.
Because there is no heated bed and extruder connected yet, I have provided this with a dummy value in the firmare.
Both establishing a connection with the board and controlling the motors via the user interface of pronterface works properly.
Loading a file (g-code) also goes without problems.
However, when I give the print command the problem starts.
the motors are briefly actuated and then stop.
On the Ramps 1.4 board, the red led keeps flashing which would indicate that commands are still coming in.
You can also hear that the motors are being controlled.
These also have the intention to start spinning but still remain stationary.
What have I tried myself:
- check all connections and reconnect.
- acceleration speed of the motors reduced
- Boudrate set to 115200.
I hope someone recognizes the problem or has a solution.
Thank you very much for your time!
