Well if you just bought one of the cheap power supplies for a prusia i3 they can Pretty much get the bed up to temp and almost no farther . basically what I’m saying is they get the bed to about 110 and never really any farther

Hi @runninred57 the electronics involved in temperature controlling something like this are really quite simple; the kit appears to come with a thermistor, so all you need to do is measure it’s value, compare that to your setting, then turn the power on/off to the plate as appropriate. The trickiest part would be calibrating the thermistor (ideally you’d need an infra-red temp reader to check it), but that’s not an unsolvable problem and, once calibrated, it shouldn’t need doing again.
Because I’m lazy, I’d probably use a small Arduino of some flavour, an LED display for the temperature to set, a power switch and a couple of up/down micro-switches (maybe a few components for the circuitry). You could print an enclosure for it and you’d be set.

me too.
Hi guys, i already replied to some of you in a personal message. It took way longer than expected to bring the 5th gen thing on the market, cause we had to do a lot of certification and stuff. I will inform you here as soon as the Z18 Version is available - sorry for the long waiting, i would have liked it faster also 
thanks for the reply, are you able to provide some specs and an inclination of what it will look like, what functionality will it have? is it tied into the firmware? and a rough cost if possible thanks and hope to hear from you soon. i cant wait to start printing abs through the z18.
I’ve done some small tests with ABS and the layers look amazing but need the HBP.
Hi, it’s completely independent from the software and firmware. It has its own controller where you can set the temperature directly. So there are also no changes at the printer needed, you just replace the original build plate with our build plate system and can switch back whenever you want to the original one.
Is there a website I can check out your products? one of your posts said you have a system for the 5G, I would love to get one of those and worry about our Z18 later. Thanks.
Hello, yes but only in german at the moment and the 5th gen is not uploaded yet.
there will be a English site also.
Please lets us know when the english site is up.
Use chrome and it will translate it

Hi together, finally the 5th Gen version is ready for sale and online on ebay
I will make our international shop as soon as possible as well, there you can save a few bucks ebay fees 
If you do not want to wait you can just send me an email to info@ide-3d.de, the price will be 449 USD off ebay.
It is the complete ready to use thing, with power supply, controller and build plate. Just to plug in, slide the build plate in and set the temperature.
We will have the same thing online for the Z18 finally online soon as well 
I know it took way longer than expected unfortunately but you have to do a lot of things when it is no DIY thing…
The price for the Z-18 Version will be the same.

whats happening with the z18 HBP. Its been 9months. I will start manufacturing my own within a few weeks if i dont hear back
Hi, it is ready, we are just waiting for the product pictures and the CE certificate.
cheers

We did not test the absolute maximum but 100 degrees Celsius are no problem. For ABS we recommend 90 - not cause of any limit, but this has the best results.
If you like to tell me wich temp you want to reach, I can do a test and tell you if it works.
cheers
