Does your CNC behave better after warming up?

[Alan]

Since we are in the second week of December and shop temps are dropping, I figured this is the perfect time to ask a very scientific question. If your CNC machine had a mood, what would it be right now?

Some machines wake up calm and steady like they slept great. Others act moody until the shop warms up and then finally decide to hold tolerances. How would you describe yours this week?

I’ve noticed it behaves way better after a short warm-up routine. Nothing fancy, just letting it jog around and spin up before doing anything serious. In colder weeks like this, skipping that step almost guarantees a slightly off first part.
