Are stepper motors and/or the controller susceptible to cold weather?
I was running this fairly simple g-code at 50% federate override and had it miss steps a couple times this week. After the second time I ran it in the air several times without issues, and also re-ran 6-7 times successfully after that. We have had fairly cold temperatures, but have my propane heater running in the garage.
I shut the controller down and spun the shaft by hand with little resistance.
I marked the G-Code below where the missed steps happen, during a rapid between two small pocket operations.
