Hello guys,
Before starting this topic, I have read all similar posts, but couldn't find the answer so I have to ask for help here.
Machine (brand new) was working for about 5 days and after that, during rest machining PC suddenly freezes (axis, spindle) and I couldn't move mouse or hit Stop/Reset... After 10-20 sec, the PC unfreezes, Spindle starts spinning up and G-Code continue executing normally. Than I was able to hit feedhold (pause), but machine stops after 5-6 sec. Also, I have noticed that Machine looses its coordinates for few mm each. After that the same issue happens randomly with different tools, codes, but at the same way.
Also this one thing might be helpful in finding the cure: when jogging at rapid (12m/min) w/o G-Code loaded, it runs smoothly, but with G-Code loaded it sometimes shakes a little, like it got uneven pulse train for a while. Bridge is over 200Kg weight, driven by AC Servo, which makes very unpleasant behavior.
The PC is brand new, with the following config:
Intel Celeron, Dual Core E3400 2.6GHz
1GB DDR2 RAM
GigaByte GA-G41M-ES2L rev1.1
Win7 Starter
Any hint will be helpful.
Cheers
