Configuring Marlin for RAMBO

I have a MendelMax 1.5 with the 8 by 8 red heat bed and a Jhead single extruder. Nema 17 motors. 100 ohm thermistors. 3 mechanical endstops.


Has anyone configured Marlin to work with this setup?

What else do I need to know to get this to print.

I have the board connected to the printer with firmware loaded and connection confirmed in Pronterface.

I can get the motors to home. But, no response to smaller step commands.

I suspect you have 100K ohm thermistors, but that's not really your issue.

You will need (as a minimum):

1) The correct steps / mm settings for your X,Y,Z and E motors
2) A rational set of maximum feed rates (try 200,200,2,40)
3) The correct end stop types for your end stops (min or max)
4) The proper home directions for your switch locations
5) The right thermistor table for the type (brand) of 100K thermistor you have. Table 1 is a good bet.
6) The right main board number for your Rambo.

Once you do all that, grab a volt meter and set the Vref's properly for the current rating of your motors.
