[TKL]

Time has come for chippin in for the Group buy. Please go here to make your payment:

It will only run for one week from today. After that the boards will be ordered and it will be too late to chip-in.

I know that I told you that I wanted to buy two boards but conditions beyond my control have forced me to sell one of
my H-1 printer and the other is up on the sell forum now. I have been diagnosed with a serious disease and can no longer
use these printers. Please try to understand and I am sorry that I cannot buy the cards.

[timothysvec]

I just paid. That chip in is such a great idea!

[timothysvec]

My thought's are with you Carl. I wish you a fast and full recovery.

[Leeway]

Well wishes from here as well, Carl. I hope you manage or recover quickly.

[TKL]

Don't think about it Carl. I hope you'll get well soon.

[michaellatif]

Best wishes Carl! Hope you get well soon.

I thank you and all that have left messages to get better. I have developed severe spine problems over the
last 3 months and the pain is incapacitating. They are doing a battery of tests but so far all they can do is
injections and oral morphine. I'll try to let you know what I find out is causing all this when I hear for sure.
I really hope that SeemeCNC can buy the extra boards as I was going to do. they can put them on their site
and I think they would be a good seller.
Anyway, in our sell forum is the ad for my other H-1 which is still in kit form at a great discount so if anyone has
a friend that needs one, they can save a significant amount of money. I personally don't feel they are going to
control this pain very well which means I can't work very long on my projects and trying to focus is near impossible.
I would like to stay on this forum because I learn a lot, perhaps can contribute something at times and reading all
this gives me something to do. God bless you all.

Done, chipped in for three (3) boards. Thanks again TKL! Let me know if you need anything else from our end.

Now all we need is a source for some 7" x 7.5" glass able to withstand the heat. Currently I use glass from one of those garage work lights, but its alot smaller than the bed and I would love to able to use the full bed

[michaellatif]

I plan on using a 6x6 initially, its what I bought from McMaster-Carr. Maybe later I will shoot for a 7x7 pane. That will allow me to make mounts that are semi flush with the glass and don't protrude using the remaining 1/2 inch.

[TKL]

I am going the mount the board on the plastic plate on the H-1 (or some other plate) with some 5mm spacers. It will give a strong sandwich solution once the screws are tightened. Before tightening them you should be able to adjust the board to be straight. I hope that will be enough but only time will tell.

[ALeander]

I chipped in for one board.

I'll try to check back before the week is up to see if we are still short on funds.
I'm out of the country at the moment and internet access is spotty at best.

Thanks TKL for all the work you are putting into this.

Don't expect the circuit board to stay flat when heated. Also count on any plastic that close will also warp. BTDT.

Yes, the board can warp, but that is less likely when properly attached to the machine. I believe the design provides enough tie points to eliminate this issue.
As for warping plastic, I have a nichrome wire heated bed (that gets extremely hot) within 3/8" of the original unprotected plastic bed of the H-1 and have not had any warping.
If you don't provide an air gap between the heated bed and the original plastic bed, it will warp. This design allows for spacers and helps eliminate this issue also.

[ref1ection]

I've also chipped in for one since it seems worth a try at that price.

Just chipped in for 1 board with one hour to go, whew just made it. i originally needed 2 but the second machine i wanted to buy (not H1) is not available, sorry about that.
Thanks for all your efforts to get this up and going Anthony.

Looks like we are at ~50% funding, is this the level we wanted to be at? Will the folks at SeeMeCNC pickup the remaining boards?

Also a quick note: If you have not contributed and are planning on doing so. Do so soon!! The funding period ends in 30 minutes!

With a couple of boards for myself and a dozen for SeeMe John we just made it

[michaellatif]

Sweet! Whats the next step?

[TKL]

Now you just wait 3 weeks for the boards to be delivered to you.

[drkow]

is it too late to get one of these?

[johnoly99]

DrKow, John here. We bought the last 11 boards to make up the run, so once they come in, we will test them out, and if all's good, we will put them up for sale on our website.

Hi All

I would like to purchase one if there are any still available.

I missed the Group Buy info - must have been asleep!
