    Hi, I was leaving that bit for a little later as I only have an Arduino mega which is overkill for this job. (A Uno r3 is on the way for about $4US). I'll post the assembly when its "fit" but here is the general idea. microprocessor, LCD shield, driver unit which drives the two motors and a PSU off TM with a 2 way splitter off aliexpress.Name:  annealer-mega-002.JPG

    what I find "awesome" is the price of these components from china, this is then the true price that our well known retail brands are paying to make retail items we buy, they then on sell them to us for an astounding profit. What hacks me off is they are all but un-repeairable and have a carefully set lifespan, where after a few years you get ripped again!

    Yes, the ticket get clipped a few times on its way to the consumer. Ask any farmer what they get paid, compared to what the consumer pays. The manufacturer and consumer both lose...the middle is always where the profit is made, and it's made by those with the least amount of input...cruel world sometimes.

    Yes, exactly. So to control a microwave with an Arduino would be about $20 so a dedicated curcuit way less. The silly thing is for the $250 the microwave could be built with an arduino making its repair cheap and easy, but no we have to throw it away and buy a new microwave.

    PS I am currently looking for Nemu 23 stepper motors for a CNC router I want to make, $45US each for 4, want 100? way cheaper yet.
    PPS Im currently toying with the idea of making my own 3d printer....$1600 to buy, make my own? hmmm

    Thanks I have a 3D printer electronics setup coming, a 4 axis controller shield and 4 x 2A drivers with an arduino coming, cost me $11USD! I was thinking I'd make a 3D printer but thinking a bit more I realized I might as well make the CNC as it will do more. Got a link for what they are?

    Attaching motor assembly.

    Stainless steel cheese head screws 4M x 50mm from Anzor with 3 x nylocks and 4 washers , $2.10NZD each assembly so $6.30NZD per motor. Plastic was what I had lying around. but TM sellers sell sizes,

    Perspex/acrylic sheet - 3.0mm thick | Trade Me

    about $10NZD.

    This one cracked as I did it up in a couple of spots so I'll order a 5mm thick acylic piece from the above. In fact 2 as I want a base plate for the arduino.
