If you have found the best spindle for your CNC router for a spindle upgrade, one thing that must be done is adding dwell to your post processor. In this video, I upgraded my Longmill MK2 from the Makita trim router to a spindle by a company called Pawn CNC (PwnCNC).
When you upgrade your CNC router to a spindle, you must add a brief pause (dwell) in the G-code program to allow the spindle to reach its RPM. Without this pause, the spindle can start a cut before it is fully up to speed, which can break router bits or damage your project material.
In this tutorial, I explain how to modify your post processor to automatically insert a dwell command when the g-code is written. It will insert the command immediately after the ‘spindle-on’ command (M3). This ensures your CNC router waits for the spindle to speed up before commencing the cut.
Using Vectric design software as our demonstration platform, I'll guide you step-by-step on how to locate and edit your post-processor file to include the G04 dwell command, which is the g-code that initiates the dwell. For those not using Vectric, the principle remains the same: find your post-processor file in your directory and apply these adjustments accordingly.
The dwell command (G04), followed by "P" and a numerical value without a decimal point, specifies the pause length in seconds.
What the dwell command line should look like → G04P5
This command will pause the CNC router for 5 seconds

NOTE: It is recommended to upgrade benchtop CNC routers to the 65mm unit, not the 80mm unit

Spindle plug-and-play kits are available for Onfinity, Millright, Shapeoko, CNC4Newbies, Masso controller, etc
