Metal Build Plate for TAZ 5

Recently, we tried to mimic Zortrax’s aluminum, micro-perforated build plate on our TAZ5. The perforated aluminum plate we’ve used (as a topper to the borosilicate glass and heating element) has thus far been a spectacular failure, with nothing sticking to it, instead gathering up on the nozzle despite at least a half-dozen z-axis adjustments. Has anyone else tried modifying the build plate of the TAZ?

There are several bed mods running around. My own preferred modification is a 12" 3/16" thick Aluminum plate with either a PEI or a Buildtak sheet on top, which tremendously improves adhesion at the edges of the build plate. There are also several removable bed options out there.
