I posed the question to the Lulzbot team about the Smoothieboard and whether they would consider it for future or current upgrades to the Taz and future machines.
The argument is that it can provide higher resolution prints through processing power. The price isn’t significantly more expensive, and it does look like arduino style boards appear to be having a harder time keeping up with the speed and complexity of the prints.
There is much talk about it over at the seemecnc boards where the delta platform guys tend to need the additional processing power to constantly actuate the printers. I have to admit, the prints look impressive, but being a classic 3 axis CNC fellow, you cant beat the reliability and precision of the lulzbot layout when everything is tight and right.
The board layout on the smoothieboard leaves a bit to be desired, but it looks like they did their best to fit it in the constraints of the free version of eagle.
I’m currently working on replacing my laser cutter’s electronics with one. Just need to get the laser on/off working and the steps/mm configured.
The firmware design is pretty nice. It makes it really easy to configure the board or expand it.
I viewed a video of them using smoothie on a laser cutter and it was pretty impressive.
I guess what I’m wondering, is that if all else is equal (price, size, features) I dont see how the ARM processors wouldn’t make the most sense as the next move forward.
We considered the smoothieboard for the AO-100s. I’m glad we decided against it, because it took about another year+ before it was finally released. I don’t think it has good upstream management (e.g. they were part of the Trinity Labs disaster, I think). We are looking at other ARM systems though, perhaps in conjunction with RAMBo.
This is a bit different than the smoothieboard, because it still uses a RAMBo, but we’re looking at Olimex A13 or A20 boards (or similar) to drive an LCD display and control the RAMBo.
