Hello;

I have much experience with Hictop, having 2 Hictop 3DP11/12's

The Hictop web site is here though i do not see your printer's name listed.
I found many Hictop controllers on E-Bay and Purchased them for spares, as have had two die.
Now if one dies I would convert to this controller
or
An Arduino mega 2560 with a Ramps 1.6 controller as a replacement.
