  The HAWC gamma ray observatory is located at the Sierra Negra Volcano in
Puebla, Mexico, at an altitude of 4,100 meters. HAWC is a wide field of view
array of 300 water Cherenkov detectors that are continuously surveying 2sr of
the sky since March 2015. The large collected data sample consisting in more
than 3 years makes HAWC an ideal instrument to perform an unbiased monitoring
of blazars in the very-high-energy (VHE) emission. This is particular relevant
for Mrk 421, one of the closest and brightest blazars in the gamma-ray/X-ray
classified as highsynchrotron-peaked BL Lac class. In this work we present
light curves for Mrk 421 and the Crab nebula obtained with the first 17 months
of data and a new analysis framework. We compare the results with the light
curves reported in [1]. The main advantage of the new framework is the
capability to derive fluxes for arbitrary timescales. We show that both,
previous and present, methods give consistent results
