Hi there


I have put together a MDF / Wood Cutting CNC Machine. It was working fine before after a I left it unattended for a while "few months"
It as acting strangley, It shutts down and stop working after few minutes of Operation, and when this happens the Mach3 Reset Button starts flashing.


My machine is made of the followings:
• Two 4.5 N.m (637 OZ-In) NEMA 34 Step Motor for my Y Axis. (To be Exact the Leadshine Model No. 86HS45 Step Motor)
• One Of The same Motor for X and another for Z Axis.
• Y and X axis are rack and pinion with a 13 Pitch Pinion each @ 7 mm apart.
• The drivers are also LeadShine M880A
• My Board is the Typical Chinese made. The so called 5 axis Board.
• Spindle is a 3 Hp Single phase which I run it using a single to three Phase LS Inverter.
• The Structure is a Light 4”*4” (10 cm * 10 cm) Square Tube
• The Dimension of the Table is 2m*4m, So it is sort of Big but not so heavy since the thickness of Tube is only 2 or 3 mm.
• The Controller is Mach3 Version R3.041


Could it be because of faulty Limit Switch or CPU not to be claean and ....


Any Recommendation is highly appreciated.
