I built a MPCNC the firmware is preset-up for Dual XY Steppers and a Z Axis though you can disable the Dual XY Steppers and should be real close to what you would need.
MPCNC V1 Engineering Inc Software / Firmware
In configuration_adv.h remark out the lines below for single X/Y stepper motors
//#define X_DUAL_STEPPER_DRIVERS
//#define Y_DUAL_STEPPER_DRIVERS
MPCNC Build information is here so you can get an ideal if this will work for you.
Image Below is a sketch Drawn with the MPCNC, However due to my setup the Sketch's feet went off the Paper on Right side.
