[You could orient it so that it fit between the tubes; it wouldn't have as much length as if it went lengthwise, but you'd disrupt the structure a lot less.]
Do you recommend the sherline compared to the smaller 4th axis kits due to the difference in quality?
[I'm not sure what smaller kits you're referring to, but the Sherline rotary table is a high-quality tool, made in the USA, (optionally) comes with a mount for a 23-frame stepper, and is compatible with their range of chucks.]
Torchhead - I reached out to the manufacturer who confirmed that the s drive is the slave to help move the gantry. I'm pretty sure I could fit a 5th gecko drive on the side of the breakout board. It looks like there is room. What does "motor tuning" refer to?
