Good experience with healthyfatboy w/machined Al print bed

I saw healthyfatboy selling machined aluminum print beds. so I commissioned him to make one for me. This is for my PB+. We decided on MIC6 at 1/4" with a thin channel milled out for a thermistor and a platinum temperature sensor. Here are pictures of them in the channel. This bed is about 228mm square. It will be mounted on a 6016 1/8" aluminum platform on a teflon bronze bushing carriage on a rail. that will be my new Y. The sensors will be cemented in with Arctic Silver or Alumina. If Silver I will have to make sure the teflon sleeves are up against the sensor body and likely coat with CA glue so that the Arctic Silver doesn't make contact - it is not conductive but it is slightly capacitive which would reduce response time. Probably not a big issue on the print bed due to its huge thermal mass. But if it can be mitigated easily its worth doing. I digress...

The final result speaks for itself: excellent work and thank you healthyfatboy
