Mark,
I suspected that 12" might be enough, but thought a spare might be a good idea. I have the hardware and sensor coming. I have a lot of through hole soldering experience, but none on SMT, so perhaps its about time I give that a try on this. How much for just the PCB and its components? And can you program the MCU off-board prior to soldering to the PCB? (I had hoped to keep the cost of this project as a DIY at under $100, but so far I have $40 for the printer, and $50 in parts with the PCB and its components still outstanding...)
Thanks,
Roger

 

Roger,

You are correct on the part # - the one I bought is 48 inches, but  you only need 12".

I can supply a PCB and I'll be happy to mount the smt parts, but you can easily do it yourself. Say $25 usd, including shipping to the US for pcb, mounted and programmed ATtiny13 and resistor and cap. Do you have the sensor?

Mark,
In light of your kit offer, I should clarify my request for a kit, as I was only thinking of a MCU PCB parts kit (with perhaps the MCU only pre-installed?). I can modify the printer without problems, and if I could get the PCB, or MCU & PCB as a parts kit, I could assemble it if not surface mounted components. I just placed a McMaster-Carr order, and I noted that in your list, 6"x24"x.016 Aluminum Sheet  (89015K17) is actually 48", and should be (89015K114 ) for 24".
Thanks,
Roger

I am willing, within reason, to consider collecting and "kitting" the parts for the E260 conversion. One problem is shipping a 2 foot long x 6 inch wide piece of sheet aluminum. In order for me to spend that much time and energy on this I would have to make a profit. Also, we now have 2 versions to consider. I'm not really keen on making money from hobbyists, especially those on this group, but I would be providing a service for something that I have, in fact, told you how to do yourself. So I really don't feel too badly about asking $100 USD per kit for the mechanical version and $150 USD for the MCU version, not including shipping. Shipping will be at cost.

I also have a couple of modified machines that I am interested in selling. It's very hard for me to put a price on these machines, but $250 USD seems about right, considering how much time I have spent on each one.

I guess I might as well go all-in and offer to convert these printers for anyone who wants to ship me one for conversion. $175 USD for the conversion, parts included, plus shipping. Either version.

Again, I want to stress that I am happy to provide gratis, as always, all the information and help anyone wants.
