Can' get the support to print correctly sometimes

[Sk7500 2]

I am having trouble on my S5 getting my breakaway support that's loaded as Extruder2 to print a good first layer. The PLA material in extruder 1 works great. But it seems like Extruder 2 is higher than Extruder 1. I have leveled the bed about a million times. I have cleaned the drool that comes out of Extruder 2 before it self levels. I have moved my parts to a different part of the glass. I have changed material spools. I have cleaned the glass. Eventually it works but I can't pin down what fixed the problem. Are the print nozzle heights being set when the bed self levels before the print? in other words if some of the drool that comes out of the support nozzle holds the support extruder up slightly will that nozzle be too high? Hope this makes sense.

Thanks

After fighting this problem for a couple hours, I shut the machine down and now it works perfectly. Don't know if that's the fix for every time but I have one more tool to get perfect first support layers.

Restarting the machine is NOT the fix. 😒
