Hello,

For the M3 macro:

print("spindle on CW")
d.setSpindleState(SpindleState.CW_ON)
print("spindle ready")

spindle_cooling_digital_out = 10

mod_IP = d.getModule( ModuleType.IP, 0 )
mod_IP.setDigitalIO( spindle_cooling_digital_out, DIOPinVal.PinSet )

For the M5 macro:

print("Stopping spindle")
d.setSpindleState(SpindleState.OFF)
print("Spindle stopped")

spindle_cooling_digital_out = 10

mod_IP = d.getModule( ModuleType.IP, 0 )
mod_IP.setDigitalIO( spindle_cooling_digital_out, DIOPinVal.PinReset )

 

Remember that “spindle_cooling_digital_out” is the number of CSMIO/IP controller digital output.
Set this value to the appropriate one for your machine.

Thank you so much.

I've tried it and it works perfectly.

I have to say that in all my tests with code, it runs very smoothly with a huge speed boost.

It's a huge leap compared to the old Mach3.

Greetings

Not only compared to Mach3 😉

I recommend you experiment with the G64 function, and you will be surprised by what simCNC can do.
The G64 command with the P parameter is responsible for the precision of corners of a tool path.

By using a low P parameter value, corners will be cut accurately but at a lower speed.
A high P parameter value can cut corners less precisely but at a very high speed.

Note:
Setting the P parameter to 1 does not mean that all corners of a part will be rounded by 1mm.
First, the P parameter refers not to the corners of a finished part but to corners in the tool path (the tool radius causes the offset).

Secondly, the size of a corner rounding is dynamically determined by simCNC based on the following:
- machining speed
- FRO values
- drive settings (speed, acceleration, jerk)
- path shape

In practice :

When roughing with a significant stock, you can use a sufficiently high P parameter value.
This will cause the machine to run very smoothly and quickly but with less precision.

When finishing without stock, use a low P value
This will make the machine run smoother and slower but with high precision.

Thanks to this approach, in the case of roughing, you will save a lot of time, and in the case of finishing, you will gain high precision.
All in all, you'll still get shorter machining times and higher precision than with Mach3.
