    This section will explain how to rewire a plasmacam machine to run without plasmacam software and without a plasmacam control box.

    It should work for any new or old plasmacam, gotorch, or sampson system with servo motors.

    Servos are more awesome than steppers, but one downside is that a servo can run away at full speed if the position encoder fails to send a signal.

    First we will just get the gantry working. After that it's no different than building an ordinary stepper driven machine, and there are lots of existing instructions and resources on how to proceed.

    The plan is to first establish a sub-basic plasma table with manual height control.

    Then add basic height control and features.

    Then add advanced height control and features.

    Readers can reply to existing threads but readers cannot create new threads, to preserve order.

    Hint: use the "next-thread" link at the top and bottom of the page to easily navigate to the next topic.

    Any idea on how many of these have been done and how they work?

    mine works fine - for plasma - read the threads in the retrofit forum section

    haven't established height control - got delayed...

    the best part - for plasma - is that the XY servo motors are capable of blistering acceleration

    I didn't care for and replaced the oem z-axis - but it works good enough for typical plasma cutting

    the worst part - imho - is how the XY rides on springs and directly on the gear rack and X also rides on painted soft steel surfaces - that's amateur - but again, it works good enough

    I have been using my DHC PlasmaCam for nearly 10 years, but am looking at a backup in case the controller dies, as the company will no longer repair the DHC controller (or even talk to me unless I call to upgrade to the new system, and I don't like the direction it is going.
