MKS Rumba + Estlcam - Stepper Motor not working

Mostly Printed CNC - MPCNC Troubleshooting

hello guys,

i have a big problem building the mpcnc. my stepper motors dont work with estlcam 11. excuse my bad english, i do what i can ;-)
my components are:
rumba plus board ( LINK )
drv8825 driver ( LINK )
nema 17 motor ( LINK )
150w power supply ( LINK )
i did the following:
- set the jumper on the board to usb power
- connected to the pc, installed the driver and flashed via arduino ide the following firmware „https://github.com/Allted/Marlin/tree/MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop“
- before the flash i set the motherboard in configuration.h to board_rumba and the baud rate to 115200
- disconnected usb, set the jumper back to 12v power and placed the driver on the x-axis, after setting the jumper-pins below to 1-1-1
- i powered it on and set the driver voltage exactly to 0,75volt
- turned off and connected the motor
- power on and usb to the pc
- in estlcam i set everything to marlin and choosed the arduino mega and the correct com port
the programming was successfull, but nothing work. no movement on the motor, no noise. do you have any tipps?! i already changed the driver and the motor and tried all possible wiring-combinations of the motor.
big thanks in advance,
bartek

I think estlcam control only works with the uno boards.

ouch :slight_smile: that is frustrating, spent so much time… is there an alternative software that works? but i think i will go with the uno. thank you!

I think you may be misunderstanding the workflow. Generally, ESTLcam is used to generate the gcode and then you would use UGS, repetier, sdcard,or something similar to send the gcode to the mpcnc/lowrider.

You can use the uno of course, and you can use one of the versions for the 2560, but you can still use your rumba board.

you are absolutely right, i missunderstood it. but i will be not able to move the motors via estlcam, cause the board is not available in the software, right? i could use estlcam for the gcode and use then the repertier-host. so i have to test my board with the repertier-host?

You’ll have to load Marlin back on to the board, but make sure that the correct board is selected in the configuration file in the sketch. Repetier host, ultimate gcode sender, chilipeppr, pronterface, those should all work.

thank you very much. with the repetier-host everything works, so my configuration was fine! i just messed up with estlcam.
