Why would a machine suddenly start losing steps?
Hi Guys,
I'm a bit puzzled.
When my mill has been running fine for a while it sometimes starts to lose steps. Yesterday it did so again and it was the same program I had been running all week, doing several hours of more or less non stop work, where yesterday it was less than one hour of milling time.
The only difference was that most of the week I had been milling mdf and yesterday it was ocoume plywood.
Can it be that the machine needed to work harder because of the stronger material?
The steps were lost during a G00 move on the x axis, so no load. I have 6.4 Nm steppers and G00 was probably about 6000-8000 mm/minute.
