First target on my hit list for this update was the broken opto on the 3 bank drop target PCB. As mentioned in my previous update, the opto component had been ripped off the board. I had originally thought the whole drop target assembly needed to be removed from the machine to work on the PCB, but on closer inspection I found the board is attached to the drop target frame with a set of e-clips. Removing these allows you to slide the board off the back of the assembly – nice! Now that I was aware of this, I decided to push this up my priority list and repair it. A replacement opto was ordered so this issue could (hopefully) be resolved sooner than I expected.

There is rarely a dull moment in owning pinball machines as there’s always something that needs fixing or adjusting. A small fault was recently noticed in my Pinbot machine, where the left out lane switch would not register when the ball rolled over it. It was a quick and easy fix, but wanted to cover it for future readers anyway. First up, I put the game into test mode and activated the switch with my finger – as expected, the switch did not register. I then manually tested other switches around the playfield. Interestingly, the left in lane switch also did not register. Other switches were fine though. So two were switches (right beside each other) were misbehaving.

Since the playfield swap, Pinbot has been running really well and been a joy to play. Recently though, an error appeared when the machine was switched on. The game detected there were errors with 3 of the switches, and reported them during the start up sequence. They are reported as “switch adjust” errors and the knocker fires off 4 – 5 times for each one. It’s an obnoxious sound, and certainly gets your attention that there is an error. The game reported that there was an error with switches 35, 36 and 37.
Time to wrap up my work on Pinbot with a few small tasks. Recently I put together a small kit for my LAH machine which added back lit flipper buttons and thought I’d do the same for Pinbot. The whole space / robot theme should suit it nicely. I already had transparent red buttons on the machine, so I purchased a transparent blue flipper button for the left side (to go with the red / blue theme), some long neck LEDs and went through my spare parts to put together the rest of the kit to install.
This update kicks off with the safe arrival of a package from Titan Pinball in the USA. Inside, red and blue silicon “rubber” rings which will replace the white rubber and add some extra cool factor to the playfield. Also included are post sleeves, mini post rings and new shooter rod tip. I was really impressed with the customer service from Titan and will order from them again. I’m really looking forward to seeing the rings installed and how they respond during play.
