Topic: Has anyone put a Helios heated bed on their SD?

Was planing on upgrading the heated bed of my SD3 as soon as it arrives and have already got a QUBD 200 x 200 heater and a 12v 20a power supply. I noticed the Helios is really flat as apposed to the QUBD one and wondered if anyone is using it in their SD and if it works well?

I want too, but want to start from the aluminum bed system instead of the wood one.  waiting on SD to put them up on the site.

I've used/use a PCB Mk2B Heat Bed that that helios bed is more or less a clone of . Works fine.
Theres thermal images of it in use over in the Thermal Images thread I posted...

@Adrian

  • Did you have to upgrade the PSU?

  • Do you use glass with it?

  • Do you need to do anything special to have the heat displayed in repetier host?

@Gathem,

  • Yes. I just got a 12V 300W to be done with it.

  • I have, but if you've read my Thermal Images post, you'll see I much prefer using a ceramic tile due to its much greater thermal mass. Both I just clipped over the top of the PCB.

  • The PCB Mk2 has a hole in the very center to poke to thermistor through allowing you to connect it directly to the glass/tile. Its then just a matter of selecting the appropriate thermistor type in the firmware - in my case it was just the typic EPCOS 100k... Temps then appear in RH as per normal. As its directly connected to the glass/tile, I usually take 5° off the bed temps I'd use with the standard bed.
