I think your switch is on its last legs. For one thing, I reckon some internal contamination caused a bad contact in the first place, and for another the click is the flip of the contacts, so the click should be practically simultaneous with the change of switch state from closed to open. If you're ...

Symptom: During bed levelling, the nozzle drives all the way to the left (X axis) and hits the limit of travel, which results in the motor stalling with an alarming juddering sound. Cause: The X axis calibration sensor is a switch at the right-hand end of the gantry. If this switch becomes disconne...

Perhaps the switch is NC and the connection has become open circuit? Confirmed. Disconnecting the switch reproduces the symptoms you describe, and testing the switch shows it is indeed NC. [Switch contacts are described as "NO" (Normally Open) or "NC" (Normally Closed). An NO co...

What I suggest is preparing a simple cube model and printing that. If it has a hole, slice the model again but this time moved a bit in the print vo...

It would help if you can post up some video. The cat model would be already sliced ready for printing, but I presume you sliced the benchy which came out OK, so you're familiar with the process of converting an stl into gcode for the specific printer? Which slicer are you using? The "test line&...

I have no experience of SLA printing, but it seems to me that if these holes are always in one vertical column what you have is either an obstruction preventing the UV getting to the resin layer in that particular place, or a faulty imaging LCD. As an aside, be aware that if your models are hollow, ...
