Is it possible to edit the Mach3 post so it includes a pause for for 3 seconds after M3 starts my spindle?  Sometimes if my spindle is very close the the start of the tool path it starts cutting before it is up to speed.  I would like to insert 3 seconds to make sure it is up to the proper rpm before it starts cutting.

Thanks,

Hello

It would be a better to set this in Mach3

menu config/port&pin, spindle setup tabs



in the general parameters 'box', CW Delay Spin Up > give a value in seconds or ms depending of the setting in the general config (right most column > G04 Dwell in ms)



if Dwell is in ms, enter 3000 in 'CW Delay Spin Up', otherwise, enter 3

PS: I f you are using an Ethernet smoothstepper, the delay is always given in seconds, even if mach is set in ms.

Thanks David for the very thorough reply.  Only problem is I am using the Mach post with UCCNC.  I will have a look at the UCCNC settings and see if there is something similar to Mach.

Thanks!

Hello,

To add the delay in the PP, go to the CamBam system tab, post processor folder, locate your PP, search for the property 'Spindle CW' in the 'M codes' section, click on the |..| button at the right side of the line to run the text editor and change the M3 to

M3
G4 Pxxx

where xxx is the delay in ms or in seconds, depending of your software.
