I figured that if Octoprint can monitor the printer remotely…..if I see on video anything spontaneously combusting, I can remotely cut the power too!
I’ll figure out some scripting at some point to allow temperature sensors / smoke sensors to trigger the plug, but for now, it’s just a bit of fun…
And someone’s already torn one down and documented it – for which I’m grateful as there’s another rabbit hole I don’t have to follow (for now)
Some useless information about power consumption measured with this plug
- 9.5 to 16.6 Watts when Idle – probably a bit more / less when fans kick in?, lets call it 10 Watts
- 58 Watts when heating the Extruder
- 247 Watts when heating the Bed(Blimey!)
- 291 Watts PEAK and settles at 281 whilst pre heating for PLA
- 13.9 watts when driving X left and right
- 17.8 Watts when driving just Y / Bed
- 13.4 Watts when driving Z up and down – which is a suprise really as I’d have thought it would be double X due to two motors
- 261.4 Watts when Printing – (205 degrees PLA and 60 Bed)
- alternates from 261.4 to 43 watts whilst printing
So, Overall, it’s not too power hungry…Lets call it 300 watts peak.
Electricity is about 35p per KWh here…..
if you have a 10 hour print, using 300 watts (peak), that’ll cost you about 33p in electricity! in practice, it’ll actually be a bit less as the heating elements aren’t on all the time, they cycle on/off to maintain the temperature!
Summary, run the printer as much as you want!, it’s less than 4P an hour here in the UK!
