Static Spindle Rotation

[Scott Lent]

Hello,

I'm attempting to put a vibrating pneumatic engraving tool into operation on a VMC. The tool will be in a tool holder mounted in the spindle, and the air to power the tool will be supplied via a short plastic tube. Therefore, it is crucial  to have the spindle not rotate (static)

In my tool library, the engraving tool has its spindle direction set to 'static'. When I bring the tool into an operation, the direction defaults back to 'clockwise', but this is not the primary reason for this post, and yes, the Feed Calculation in the Machine Group Properties is set to 'From Tool'. At this point I am happy to change the setting back to 'static' at the operation level.

Were the real issue is, even though the spindle direction for the tool is set to static at the operation level, my post processor still outputs an M3 to start the spindle. Specifying "0" as spindle speed results in an error in the machine.

My reseller worked on this for a few days and could not come up with the fix. They offered a few ideas but they didn't work. I certainly understand I can make a simple program edit to keep the spindle turned off, but I'd like to eliminate any chance of forgetting to do so.

Anybody got any thoughts or solutions?

I made a separate tool change and start block block for the probe so that would not happen.

I tied it to the tool number but you could find the right statement to say

You would have to look at the PDF to get the correct parameter or variable

If (tool name =engraver),

Special tool change block

 

Else,

Normal block
