Quoted from MintIndeed:
Well damn, I didn't realize the magneato save was supposed to throw the ball back onto the play field. It happened a couple times very early on but never again, so I thought it was a fluke! I checked and my machine does not appear to have resistors near the magnets, like in the video you linked.
I don't mind reaching out to Spooky support, but if you or anybody else has specific tips to check out, I'm all ears! (New balls, 7deg play field pitch, latest code, checked all pattern settings...not sure about resistor settings, is that a separate setting? Also not sure about the magnet core plastic?)
I can say with 100% certainty that for me the solution for my magnet was to 'cut out' the in-line resistor as per Spooky and I found that for the front magnet you don't even have to take off the glass and pull up the PF.
Open the coin door, locate the resistor near the front left of the underside of the PF and cut the Orange/Purple wire from both sides of the resistor. As these two wire ends need to be reconnected, I cut them back to shorten the overall length. Strip both ends of the wires slip on a short piece of heat shrink tubing, twist the exposed wire together, solder and slide the heat shrink over and heat it up. Turn the game on and adjust in the settings if necessary. I've left mine set to Resistor ON (seems to be suggested) and ORIGINAL pattern. The ball is held and now thrown well up an into the playfield. I haven't tried the other patterns but will try just to see if they change the pattern. Original for me goes straight up, even into the scoop (left of the monster mode targets).
Next time I have the playfield raised I will cut out the rear magnet resistor.
Here are some pics, if that helps.IMG_20200516_1026156 (resized).jpgIMG_20200516_1027105 (resized).jpg
