<div class="paragraph"><p>plasmac2 is a GUI extension to AXIS for plasma cutting which utilises the <a href="https://linuxcnc.org/docs/devel/html/man/man9/plasmac.9.html">plasmac component</a> for controlling a plasma table from LinuxCNC master branch (v2.10) or later using the Debian Buster and later or any similar Linux distribution.</p></div>
<div class="paragraph"><p>The plasmac2 GUI supports up to nine axes.</p></div>
<div class="paragraph"><p>The plasmac2 GUI will run on any hardware that is supported by LinuxCNC master branch (v2.10) or later provided there are enough hardware I/O pins to fulfill the requirements of a plasma configuration.</p></div>
<div class="paragraph"><p>There are two available formats, both with user selectable sizes:</p></div>
<div class="ulist" id="plasmac2:formats"><ul>
<li>
<p>
landscape with a minimum resolution of 798 x 456
</p>
</li>
<li>
<p>
portrait with a minimum resolution of 644 x 720
</p>
</li>
</ul></div>
<div class="paragraph"><p>Minimum resolution is obtained by using a font size of 7, the font size is selectable from 7 through 20.</p></div>

<div class="paragraph"><p>Installing plasmac2 is a bit convoluted due to there currently being no way to directly install it via the standard LinuxCNC configuration wizards.
At this time it is necessary to have a working copy of QtPlasmaC and then migrate that to plasmac2 via the plasmac2 migration tool.

<div class="ulist"><ul>
<li>
<p>
The current LinuxCNC version must be master branch (v2.10) or later.

<li>
<p>
A working QtPlasmaC configuration must be installed.
</p>

<li>
<p>
The <a href="http://linuxcnc.org/docs/devel/html/plasma/qtplasmac.html#plasma:initial-setup">Initial Setup</a> procedure for QtPlasmaC must be completed.

<div class="sectionbody">
<div class="paragraph"><p>To begin a migration, call the migrator from a terminal by using one of the following commands depending on the LinuxCNC installation type:</p></div>
