Informative. I have been ignoring this feature. I won't be doing that anymore. Thanks.

Hi. I'm running Mach 4 Hobby (version 4.2.0.4322) and don't see a 'Spindle Warm-Up' option. Do I need to download a plugin, or the latest version (4.2.0.4612)?

For anyone still using Mach3 (I know, I need to upgrade!), here's a quickie GCode to turn on the spindle, dwell/pause, change speed and repeat

Mike I am using Mach3 as well. I don't know much when it comes to writing code, or understanding it. For the code that you posted, do I need to copy it into a text file and then just load it like a gcode file and then hit start? Thanks in advance.

[@MikeHatalski]

@@rchavez5056 Exactly, that's the way I use it.
It should cycle through spindle speeds of 6K, 12K, 18K, & 22K, waiting 60 sec at each speed.
Good luck!

[@rchavez5056]

@@MikeHatalski thank you sir.

[@nerdmanpap]

Why can the warmup not be run with a tool in place? It would be much easier if you could leave the cutting bit installed for the warmup

[@Dave-ni4vg]

Is there a reason you cannot leave tool installed?

[@MichaelWoodrum]

Is this for any of the spindles? Why is this just now being talked about if it's necessary and I've had my cnc since 2017?
