I received the heated build plate I order for my replicator 2 (http://bctechnologicalsolutions.com/hbp/index.html) and I must say that it is great. Bottleworks really did a fantastic job making a professional product. Installation was easy and there was no modification to my Replicator 2 for the installation. Everything works as designed.
I generally use Makerware for prints and there is a modification to the device definition required to force Makerware to allow configuration of the platform temperature for a build. Thanks to Guidozelf for figuring this out (Makerbot Operators). Basically it involves modifying three section in the in C:\Program Files (x86)\MakerBot\MakerWare\s3g\profiles\ Replicator2.json related to the heated platform. These sections are copy and pasted from Replicator2X.json in the same directory for reference.
This is my file that is working (no mods from the default except the HBP sections):
One thing I noticed when testing the heat is that the stock z-arms sag quite significantly when the build plate is heated. I was planning on buying his aluminum z arms http://www.bctechnologicalsolutions.com/arm-upgrade/index.html I just didn’t expect to buy them so soon. Oh well they are on order and hopefully I will get them soon. No worries printing with PLA does not need heat (most of the time).
