Sorry guys going to have to bow out of this little project for a while. mhemling has the prints. I have an emergency that has come up I have to attend to.
I hope all is well!

I'll print the next revision of the case when I get a chance.

update on the case? Looks like sinner has one ordered already :thinking:
His is a custom thingy, still drawing it up in CAD. Still having troubles will warping when printing. Wondering if the print surface has something to do with it.

I have been busy building a bridge lol I have to build a balsa wood bridge as an engineering project. I will try to work on it thursday-friday night but I have finals next weeks so I can't spend too much time on it.

Is the print surface temp adjustable. The ones I have from rusty seem to curl a little bit except the one piece he drew up that was really thin. He was saying that the walls being thick causes problems. After you lay the initial 1/16" shouldn't the plate begin to cool down? I could be wrong as I don't have a printer but it makes sense to me.

You can set the temperature of the first layer, then another temperature for the rest, from 0-120 deg C

Is it a gradual decrease or do you manually do it. A sudden change in temp i imagine would warp it. After you have a sufficient base I would try to get to a med-low temp as quickly as possible in a linear ratio that way the majority of the print is less likely to warp from temp differences. Lol again I have no idea really what I am talking about this is just a guestimation.

I don't think I can manually set it when printing. It takes about 20 mins to cool from 120C to room temp, so it's pretty gradual.

There is no such thing as a cheap pre-built LPM. The TEC unit is $150 but its back ordered for months. You can get the ophir unit hut its $300 or you can get a blue fan basic but not sure how expensive they are. Iirc they are under $200, but talk do some reseatch prior to buying anything. ARG is a great guy and builder but if you dont have a need for an ophir then no use buying one.. Im getting a ophir but I have the $300 and a need for one.

Wait so can u buy these prebuit or is it a diy build. Trying to find a non-diy cheap lpm.
Although the above LPMs are quite nice... you could also
consider a calibrated LaserBee LPM product.

There is also an exclusive LPF Members Discount available
to eligible LPF members...:beer:

You can click on the links in my Sig for more details.

the blueFin is a very inexpensive but quality product! many member have had this LPM and if you don't want to spend and arm and a leg on a expensive LPM that would be a good choice!
