Symptoms
When the nozzle goes down to place a device into a socket or other location, the device remains on the nozzle.
As the nozzle returns to the Z home position, the device will then fall out of the nozzle.
This issue can occur when changing jobs from large devices, which rely on gravity to assist them coming off the nozzle and small devices which need to be blown out of the nozzle.
On occasion, this can happen quickly and look like a placement issue.
Checks
- Check the main air input regulator, it should be in the region of 80psi.
- Check the puff off the regulator, located behind the air regulator panel on the back of the system.
- Operate the I/O settings for vacuum and switch it on and off, with your finger over the nozzle. Can you feel the vacuum drop off quickly when switched of, or is a slow release of pressure? If it is slow, then there is insufficient or no puff off.
- Remove the puff offline to the MAC Valve, this is a thin clear pip on the head assembly. Switch on the vacuum, can you feel air blowing out of this pipe?
If yes, then puff off air is present. Replace this airline and move to step 5
if no, there could be a leak or a kink in the pip in the echain. Check the output from the puff off the regulator.
- Remove the thin clear pipe from the MAC Valve, which has the T Piece and connects to the blue inline filter (if fitted!!). Switch the vacuum on and off, can you feel the puff off?
If not, then the MAC Valve is faulty, check and replace.
If yes, then replace the pipe and move to step 6.
- Remove the clear pipe which attaches to the Z Spline. Switch Vacuum on and off, can you feel it on the pipe?
If no, then the blue inline filter may be blocked, try removing it and test again.
If yes, then there could be a leak on the spline, check and adjust.
