14. A few practical notes about Mach3 program and CSMIO/IP-A
Here you can find few tips that can help users unfamiliar with Mach3 program.
1. Computer keyboard.
a. Do not use a wireless keyboard, sometimes this keyboard record keystroke, but does
not notice releasing it, which can be very dangerous while controlling the machine.
b. Also – an USB keyboard can behave in unpredictable ways. The USB port is not
resistant to interference therefore, especially on machines with servo drives and
higher power spindles. We definitely not recommend the USB keyboard.
c. The most reliable solution is PS2 keyboard or connection of industrial buttons to
CSMIO/IP-A digital inputs and defining them correctly in Mach3 program.
2. Remember that writing down the value in any text boxes on the Mach screen - must always
be confirmed by pressing ENTER.
3. If you are doing CNC programs at high speeds
and sometimes the movement loses its
smoothness, check the „LookAhead” parameter in "Config / General config". It is responsible
for sections of the trajectory analyzed in advance. Set this parameter to 999.
4. If you are doing CNC programs at high speeds and you notice some distortions related to
rounded corners then switch on and experiment with "CV Dist. Tolerance" parameter in
„ConfigGeneral Config”. At the beginning you can set the value on 0,5 - it will correspond
to 0,5mm corner tolerance.
5. Mach3 program as a decimal separator (to separate the fractional part) uses a dot „ . ”. Keep
it in mind entering the values.
6. 3D trajectory preview on Mach screen can significantly burden the computer when the files
are large. While the machine runs, do not do operations such as zooming, rotation, etc. For
very large files, we recommend to turn of the 3D preview - Diagnostics screen, click
"Toolpath on / off."
7. If a machine has touched a hardware LIMIT switch, you can back of the switch by "OveRride
Limits" button activation on Settings screen. It is also convenience to activate "Auto
LimitOverRide" - this will cause that when we touch the limit switch a machine will stop, but
you can click RESET and back of the limit switches without any additional operations. Addi-
tionally the "Smart Limits" function activated will protect you against motion in wrong direc-
tion, which can be cause by e.g. accidentally wrong button pressed.
8. Manual control (JOG).
