Are you working on that thing in a hallway? Tight quarters.
Seriously, I enjoyed your other thread and look forward to monitoring your progress on this machine. Like radium mentioned, I too think this one is underrated.

Per the vid guide, if using latex, use the best quality latex they have:

Then do a test print on plain paper and check it!

vid1900 would be proud!
You guys do those repairs the right way!
Keep it up.

check your connections on the switches in the same row as tilt, perhaps a diode leg is making contact where it shouldn't be?

How close is your nearest neighbor, can you run an extension cord just to test?
What about a portable gen set, have one of those?

This thread has become popcorn worthy - well for me at least.

Right, but with the IGBTs firing... does that not introduce noise by design, hence some of the primary problems with DC power inverters?

OMG
This was AWESOME

you two are amazing (jsa & @quench)

How on earth did you think of this!!!

... and the crowd goes wild...

Actually yes, you should request a power quality study be provided by the solar power company. Your results have ramifications they need to consider. Your product that was effected is a pleasure device, what about those on life saving electronic equipment. They should be very interested in providing a product to the market that can filter out such harmonics?

Or just move.

@Quench, this one is white paper worthy!

Hmm, why not one sized for the whole power supply to your residence? I mean if YOU'RE not the one going to pay for it.
