WM800 - WR-DCM3 - Trouble shooting

 


Axis motor tension of the top belt

         Bolts (4 pcs. each) of the 2 axis engines (left side) must be tight.

         Bolts (4 pcs) of the engine bracket must be tight.

         Tension of the top white belt must be according to the specs.

 


Spindle jaws spindle axis mounting

         Bolts (6 pcs) of the jaws to the spindle

         Bolts (3 pcs) of the spindle to the axis

         Bolts (4 pcs each) of the 2 bearings of the spindle axle



Mounting of the tool holder

         Bolts of the tool holder to the axis must be tight.

         Bolts of the tool holder must be tight.*

         *NOTE: lowest bolt needs to be tightened first before tightening the upper bolt!

         After the tool holder has been replaced or changed the machine needs to be calibrated as explained in the manual


 

 

Tension of the spindle belt

         Tension of the drive belt of the spindle must be tight



Spindle allignment

         Check if the spindle is aligned using a measuring clock. Check both the disk under the spindle as well as the spindle itself.


 


Axis cleaning

         Remove the left and right black plastic covers of the axis by unbolting the screws (3 pcs each side). Remove aluminum chips from the spindles and axis using a        vacuum cleaner and/or a brush. Make sure the sliders are free from chips as well. Lubricate in case the grease was removed with the recommended grease.

         Aluminum chips removed between the teethed wheels and the axis (top left and right)

         Grease on the threads which move the axis (see manual)


Location tool holder

         The top of the tool holder may never be lower than the center hole (between the screws)

         Always tighten the lowest screw prior to the top screw

 


Problems limit switch sensors

       In case there are problems with the limit switches follow the wiring and check the connectors by disconnecting and reconnecting them

         Check if the lights on the sensors are on

         Check the connectors at the back of the axis

Problems with the laser

     Check the connections between the laser and the connector. Disconnect them and reconnect them to see if the problem is solved.


Problem with the power

        Remove the top back plate from the machine by removing the 4 bolts. On the left there are 4 safety switches which should be “on”.


Connection problems

         At the back of the machine check all the connectors


Cleaning

         The product must be inspected and cleaned at regular intervals.

         Do not use compressed air for cleaning. But instead use a brush or vacuum cleaner.

         Remove large particles and dirt from the surface at regular intervals.

         Use only neutral cleaning agents for cleaning.

         Use only damp, soft and lint-free cleaning cloths to wipe the surface.

Cover strip

The cover strip is Teflon-coated. The friction causes abrasion on the cover strip.

         Remove abrasion products at regular intervals.

 

Lubricating the linear guide and the drive elements

 



 

 

The ball screw axis is lubricated with grease from an internal reservoir. The reservoir is factory-prefilled. The carriage features 3 grease nipples at each side for relubrication.

       The outer grease nipples are used to lubricate the linear guide.

       The inner grease nipples are used to fill the drive element (ball screw drive).

Notes on greasing


When applying the lubricant, you must not exceed a maximum flow rate. Therefore, the minimum injection time of 3 seconds per grease gun stroke must be adhered to.

The carriage must be moved between strokes of the grease gun to allow the grease to distribute evenly in the lubricant reservoirs.


 


Lubricating the linear guide

Position the nozzle at a right angle. Press the nozzle against the grease nipple.

Inject the correct type and volume of grease into the two outer grease nipples at one side of the carriage.

 


Lubricating the drive elements

Position the nozzle at a right angle. Press the nozzle against the grease nipple.

Inject the correct type and volume of grease into the center grease nipple at one side of the carriage.
