Mach3 always starts with tool „0” chosen, if you use a tools changer and some tool left
in a handle when you turn off, then after Mach restart, you must enter this tool number
(Tool Information group on the main screen, the "Tool").
a.
If you do not use a tool changer but you have an automatic tool-length meas-
urement sensor, then after starting Mach program always enter „1” <enter> in-
to the “Tool”. Similarly, when generating the g-code file in CAM program also
always set the tool 1.

STOP button on Mach3 screen stops a machine instantly. With stepper motors, it may
cause that motor will fall out from the position, with servo drives, the motor controllers
may report an overload error or overstaying error and you will need to re-home the ma-
chine. Recommended way to stop the work is pressing pause first („Feed Hold”), and af-
ter it stopped – the STOP key.
11.
To restart CNC program from specified location - set in G-code window desired position
(line), then press "Run From Here" and then "Cycle Start".
12.
It is worth to know the basic commands of G-Code. In many situations the MDI Mach
screen, where you can manually type the commands that are executed immediately is a
very useful tool.
13.
If you have a tool magazine and/or automatic tool-length measurement sensor, remem-
ber that any manipulation/repositioning or disassembly of HOME switches can cause
machines absolute zero position shift and then recalibration of magazine and tool length
measurement sensor position is necessary.
14.
If you set the zero point (material base) and you use an automatic tool measurement –
always make the tool measurement first, and then set the zero point. Setting the zero
point with unmeasured tool causes that the level of processing shifts when we place an-
other tool and call the measurement.
15.
A PC computer you use to control the machine should be treated like an integral part of
the control system and should not be used to any other tasks. It means that, this com-
puter should only have operation system, Mach3 program and nothing else (eventually
text editor and file manager such as Total Commander®). For any other tasks such as de-
signing, you should use some other computer.
16.
On the computer you use to control you should disable all visual effects of your desktop,
screen saver, and turn power profile on “always on”.
