If the blade does not drop properly during cutting, the most likely cause is a malfunctioning mainboard. The blade-down action depends on the Y-axis motor signal sent by the mainboard. When the mainboard fails to provide that control signal, the blade will not lower. The documented remedy is to replace the machine’s mainboard, after which the blade should drop normally.
Documented Symptom
The documented symptom occurs during cutting: the blade does not drop or lower properly. This troubleshooting guidance applies specifically to that blade-down failure. The issue concerns the action that lowers the blade rather than a separate cutting operation or an unrelated machine function.
Most Likely Cause
A mainboard malfunction is the most likely cause of this symptom. The machine’s blade-down action is controlled by the Y-axis motor signal from the mainboard. If the mainboard fails, that signal does not correctly control the lowering action, and the blade remains raised instead of dropping as expected.
This identifies the mainboard as the component associated with the documented failure. The supplied guidance does not specify another supported repair for this symptom.
Recommended Fix and Part Support
- Identify the applicable symptom: Confirm that the problem is the blade failing to drop properly during cutting.
- Replace the machine’s mainboard: Mainboard replacement is the documented solution for restoring the blade-down action.
- Request the replacement part if needed: Contact your local distributor or the seller of your machine to obtain the required mainboard.
No additional adjustment or alternative component replacement is documented for this specific blade-lowering problem.
Expected Result After Replacement
After the machine’s mainboard has been replaced, the blade should drop normally during cutting. Normal blade-down movement is the documented verification that the replacement has addressed the issue.
If you need help obtaining the replacement mainboard, contact the local distributor or the seller of the machine. These are the supported channels named for replacement-part assistance.
