Ill post some links in the morning when I'm on my workstation.

I know quite a few people with that printer, they all love it.
which are you referring to? The Maker Select Plus, or the Ultimate?

The Maker Select is the one I was speaking of.

There is a Z-axis brace mod, that is reported to help quite a bit:

Z braces for Wanhao Duplicator i3, Cocoon Create, Maker Select, and Malyan M150 i3 3D printers. by AzzA - Thingiverse


I've also heard that a hot end upgrade to something like this is well recommended:

Micro Swiss LLC


I've had my eye on the maker select for awhile now, I will likely pick one up before too long. The above mods were recommended to me from a few maker select owners.

Monoprice is doing a promotion today. Use the code "friday20" to take 20% off any order over $100. That drops the printer price to $320.

Ran into this article last night:
CES2017: Monoprice Unveils Expanded Line of 3D Printers | Hackaday

Might be worth waiting till April to check this one?

"The Pro Filament Printer
If you jump over to Monoprice right now, you’ll notice they really have the ‘good, better, best’ market segmentation down with three printers that cost $200, $400, and $600. The huge SLA printer shows they’re ready to jump into the pro market, and for filament printers they’re offering the MP 3Series Commercial 3D Printer (or 3Mill, according to the engineers). It’s a printer that can print a 400mm cube, and it costs $800."

That could print a 15" waveguide!

SLA also sounds interesting, but.... expensive!

I'm a big fan of using multiple printers to print large objects.

For instance:

The waveguide in this thread took 32 hours to print and measures 8"x8"x6"

Scale that up, and we see that a waveguide measuring 16"x16"x12" would take about five days to print

But if you 'slice' that waveguide into four pieces, you can print it in 25% as long on four printers simultaneously

Besides being able to print faster, it's also less maddening if one out of four prints fail, then if one print fails that took four days to print


Also, because you can arrange waveguides at a 45 degree angle, you can print larger than you might realize.

For instance, the printer that's on sale for $320 today prints 8"x8"x7". But if you rotate the waveguide 45 degrees, you can fit one that's 11.312" wide. This assumes the coverage angle is 90 degrees. If the coverage angle is narrower, the width will shrink.

Split the waveguide down the middle, and you could print a 20" wide waveguide on the $320 printer. This assumes a height of 7" or less.

Turns out all 3D printers are on the "excluded list", so the discount code won't work there.

IMHO, you should use a very good stereolithography printer to achieve 0.1mm and it would be a very difficult objective
