So far so good...now tell us a little bit more about the Degree, did you get your monies worth?

That design looks like it will do the job, consider beefing up the bracing on the sides, there is no such thing as a frame that's too stiff. Also have you thought about linear rails such as MGN-12H type? They are better than roller wheels and not that expensive now. The chinese ones work fine.

I have only used one machine with wheels a delta, its not the wheels that are the issue its the printed carriage they are often attached to. If you are going to use metal carriages then the wheels should compete with the rails. To be fair I've 3 machines all using rails and am totally happy with them - zero play.

If you ever intend to print ABS you will need to enclose the printer and keep it warm inside. It's best to plan for that now. That means use a frame design that makes enclosure easy and plan for the electronics to be away from the warm print chamber.

The design was actually heavily influenced by this printer: Openbuilds v-slot z axis for Lulzbot Taz 4/5 Printers

Do I really need to enclose the entire print area to print in ABS? I had the understanding that it was just the print bed which should be heated?

Thanks for the clarification. I had missed that in my research, which I do see now is a little sloppy. I would in no way start by making a printer that can work with ABS, but it's nice not to close any doors, and when I have mastered the basics, I would like to move forward with, for example ABS.Quote

You can print very small objects and even large single walled vases in ABS on an unenclosed 3D printer, but if the objects are long and narrow or have any bulk they will tend to pull themselves apart at the layer boundaries. Designing the machine to print ABS is much easier than adding the capability later. Designing for ABS includes easy enclosure, moving electronics away from heat, having no PLA printed parts (and minimal ABS parts, too) in the machine, adequate heating for the bed -look for a 0.4-0.5W/cm^2 (or more) heater, and preferably, an all-metal hot-end that won't mind high temperatures. The bed heater will determine the required power supply (use 24V instead of 12V), and that may affect the choice of controller. For a 400 cm^2 bed you'll want about 200W or more bed heater or you'll be waiting forever for it to heat up. You need the bed to get to 105C or so for ABS, even higher for polycarbonate. You can save some money and improve reliability by using a line powered bed heater and SSR to switch it on and off, but you have to be comfortable with wiring line powered electronics. That means you can use a lower power, lower cost, physically smaller, maybe even fanless, supply for the rest of the printer.

You have had some good advice and if you follow it you'll have a really good printer (and spend quite a lot) but then quality isn't cheap.
It's a case of differing points of view in term of what is money well spent on components.

These Chinese rails really are ruining my prints.
