The air spindle runs anytime its in the spindle so no M codes are need. As we only have one option for RPM I'd like the post to error on anything but the standard range 1-10000 except on a 40000 S call, possibly adding a dwell if we needed.&nbsp;</P><P>&nbsp;</P><P>Learning and trying things here is where I'm at, but not successful yet.</P><LI-CODE lang="general">var spindleChanged = tool.type != TOOL_PROBE &amp;&amp; (insertToolCall || forceSpindleSpeed || isFirstSection() || (rpmFormat.areDifferent(spindleSpeed, sOutput.getCurrent())) || (tool.clockwise != getPreviousSection().getTool().clockwise)); if (spindleChanged || (operationNeedsSafeStart &amp;&amp; tool.type != TOOL_PROBE)) { forceSpindleSpeed = false; if (spindleSpeed = 40000) { } skipBlock = !spindleChanged; writeBlock( sOutput.format(spindleSpeed)//sOutput.format(spindleSpeed), mFormat.format(tool.clockwise ? 3 : 4) ); if (spindleSpeed &lt; 1) { error(localize("Spindle speed out of range.")); return; } if (spindleSpeed &gt; 10001) { error(localize("Spindle speed exceeds maximum value.")); } skipBlock = !spindleChanged; writeBlock( sOutput.format(spindleSpeed), mFormat.format(tool.clockwise ? 3 : 4) ); }</LI-CODE><P>&nbsp;Thanks in advance.</P><P>&nbsp;</P> Sat, 23 Apr 2022 18:57:29 GMT https://forums.autodesk.com/t5/hsm-post-processor-forum/air-spindle/m-p/11124370#M3628 Claytonics 2022-04-23T18:57:29Z https://forums.autodesk.com/t5/hsm-post-processor-forum/air-spindle/m-p/11124776#M3629 <P>I think I got it.
