Resets
If you save and restart you will often face this message. This is because the mightyboard can not reset itself over USB. Hitting restart will usually allow you to connect. However if the printer halts due to thermal runaway, emergency shutdown, etc. You will have to manually power cycle the printer.

There are a couple of potential starting points for a replicator config. The Flash Forge Creator Pro has certainly received more attention and is almost the same printer. Sgail7 has tried to give the entire early replicator family support in klipper. However their config seems to have some serious issues at the time of writing such as the kinematic set to CoreXY. It still served as a template for my first pass at writing a config. https://github.com/Sgail7/Replicator-Revival-Project/tree/main/Klipper/Configs/Replicator 1 Configs

# G130: Set digital potentiometer value
######################################################################
# The macro below uses the MCP4018 SET_DIGIPOT command to implement
# a `G130` as used on classic Mightyboard-based printers such as
# The Makerbot Replicator 2/2X.
#
# The `G130` command can be used to lower the stepper current
# during preheating and raise the current again prior to starting
# the print. This is necessary for printers with smaller power
# supplies that needed all the power to heat the bed.
#
# This macro requires one or more [mcp4018] configuration sections:
# (x_axis_pot, y_axis_pot, z_axis_pot, a_axis_pot, b_axis_pot)
#
# Example: G130 X20 Y20 Z20 A20 B20 ; Lower stepper Vrefs while heating
