I have a Printrbot LC Plus that I am modding and need help picking a good PSU for it. I'm currently using a PC PSU and it takes forever to heat up my bed so I hope I can eliminate that with this upgrade. Here are the new things I'm changing and why I want a new PSU: * Kraken (So 3 more extruder motors/heaters & the water pump) * Azteeg X3 Pro (Why does it have 3 different PSU hookups?) * Laser cutter : http://jtechphotonics.com/?product=new- ... er-adapter Im also adding one of those Z axis sensors that are on the newer Printrbots but that shouldnt matter in this.. I contacted Panucatt and asked for their suggestion of one and they only gave me a brand "Meanwell". But they have so many different types and models I have no clue which to pick. I'm only used to messing with PC PSU's. My heater bed is the Helios which is labeled as 12V so I dont believe I can do a 24V PSU. Thank you for any help you can provide! -D
Most heater beds are rated at 12V but a lot of people run them through a solid state Relay and use 24V, the 24V power supply Attaches to the output of the SSR and the heater bed and the output of the driver board for the heater bed connects to the input of the SSR. Many have done this and the heater beds do not normally burn out but get hot a lot quicker.
I did that on my current 12V PSU. But if I went 24V and did the SSR for the heater bed wouldnt everything else still need to be able to handle 24V? The Kraken heater cartridges, the water pump, any fans & led lights? Would it affect the stepper motors? sorry if these are silly questions, i dont want to blow something up pumping too much power through it.
The 24Volts would normally connect to the Heated Bed via an SSR. The 24Volts would also connect to a 12V converter that would feed the Rambo and all accessories. Here is a link: http://www.amazon.com/HOSSEN%C2%AE-Conv ... +converter
Oh thats really cool! Thanks for that! So now I can focus on finding a 24V PSU for the faster heater bed.

Sweet thanks! I got that Meanwell one. I liked the idea of that HP one but apparently in the fine print that was a parts only, broken or something. I also ordered that converter. Thank you for all your help..
Meanwell is the brand I also use. They are getting hard to find because so many are being bought up for 3D applications. Have a great printer!
I just had to come back and thank you one more time Eaglezsoar.. I got the 24V PSU setup with a relay and hooked it up just to the bed at the moment and WOW, heat up times went from like 20+ minutes to like 5 minutes. Thank you for your help!
I would recommend 2W or 6W from Opt, I myself use 2W for smaller tasks. I haven't seen much info on Opt Lasers here -very good quality lasers they have: https://optlasersgrav.com/
