engraving machine cannot be started performance:
once started. The equipment can not run. Maintenance personnel during the inspection, they found a power tube is damaged, but since there is no data, lost the role of the tube, thought is driven power forward, put on a power tube, after electrify, burned again, change the tube is damaged.
engraving machine cannot be started cause analysis:
the initial analysis of woodworking engraving machine is to fuse the insurance, the professional maintenance personnel to check. Drive certainly exist an unusually large current, and check out the damage of power tube. But is not clear for the role of the tube. In fact the pipe for step motor drive power, step motor for high voltage starting, therefore to accept high voltage large current. Static inspection, found that pulse annular divider circuit, the power supply to the side resistance is very small, but also not short circuit. According to the number of components in circuit power supply to the side resistance and power consumption analysis should not be so small, so doubt existing components of the circuit to be damaged.
the floating head just as its name implies is the sculpture in the plane, can fluctuate within a certain range. Spindle on the Z axis is sliding up and down, pay attention to when using the floating head to adjust the distance of the cutting head and the tip, float can be carved on large area of the uneven plane, while keeping a uniform depth of the engraving. Many domestic engraving machine said their carving machine with floating head but some floating only - of the cutting tools A simple knife nose, used to pin processed objects, less than the real role, or motor too heavy floating up, or machined surface scratches. Light or motor power is not enough that has a problem.
engraving machine cannot be started solution:
1, the change of pressure in considerable stepper motor power supply current drive pipe, to further confirm the problem of the chip.
2, and restore the chip power supply pins, using leds to replace stepping motor's winding circuit simulated load. After electrify, leds are bright, namely each winding are electricity, it is not meet the requirements of the line input step pulse response, thus confirm the chip has been damaged. But not on the chip market, drive casing under the condition of space allows, using the combination circuit which USES existing D flip-flop at hand and the combination of the nand gate design an annular pulse generator, production on a small PCB, removal of the original chips will small PCB by pin is installed on the original chip bonding pad. Still using light-emitting diodes as simulation load, after electrify plus one step pulse according to the phase sequence in turn to shine.
3, removal of simulation load, access to the host, electricity, equipment running normally.
the engraving machine to remind customers, you yourself don't know more than is the case of don't disassemble, please contact your engraving machine manufacturers warranty processing, lest penny wise and pound foolish.
