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.

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

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,
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,

It is possible to program smt chips before mounting them, but the zif socket is a bit pricey. What I usually do is provide pads for a header to program the chip in-circuit. I'll be a sport and send you the pcb with a mounted and programmed mcu for the $10 you have left. Send me $10 via Paypal, or a check and I'll get it out to you. I'll throw in postage if you're in the US.

Mark

A very minor typo in the PDF ...OBP705WZ IR reflective Sensor Digikey (365-1921-ND)should actually be ...OPB705WZ IR reflective Sensor Digikey (365-1921-ND)and you can add the Mouser part number (828-OPB705WZ) if you'd like.And thanks for making all of your work and information available to the rest of us!!!

Are there a board level and system level schematics of the MCU mod?I looked in the files section of the group and didn't see any.Are the MCU boards artwork and firmware available?Where is this PDF mentioned located?Thanks

 

The schematic and source file is in the files section of the group, as is a drawing of the pcb. It is extremely simple and would only take a little work to replicate. Unfortunately the schematic is a drawing only, it cannot be used to create a board. I do have the board in Eagle format and would be happy to post it or send it to anyone who wants it.

I think you have done a fantastic service to us all.
I have often thought about DLP but have always had too much other stuff on the go.
I looked at your source code and thought it wonderful to see someone else use assembler language.
There are not many of us who do. I always find it interesting to look how another person attacks the code and puts it together. I know for me that I get set in my ways and always repeat what has worked for me in the past, Its interesting to see another flow.
Anyway great work and I will sometime in the future give your DLP a go. I have quite a lot of Photo sensitive board still in stock so I will use them up first.
Thanks for your dedication

Hello Mark

I am about to embark on building your design.... I too am having problems finding E260's that are "reasonably" priced... I have however found a E360.  I see hints to it here but is it any different than the E260....

Also do you make, program and sell the MCU board?

Thanks

Tom
