It sounds good. I eyeballed the current on my ORD Bot-like machine to the point the steppers become warm after a few minutes. The belts as tight as I can get them with the tensioning system I have (slacken screws retaining idler mount, re-tighten while pushing belt taut with thumb).
The one thing that worries me is that increasing current on one axis seems to have a detrimental effect on the other axis -- unless that's you messing with more than one thing at a time. Is your power supply adequate?
Hopefully it will work smoothly for you from now on.
* * *I have tried to express the idea that people who have a good understanding of a system (e.g. the printer electronics) have a better chance of getting it to work perfectly "out of the box", because they are aware of possible failure modes and work to avoid them, often in subtle ways and/or without being aware that they are doing so. This is knowledge that is often not visible to an observer. For instance, I know how to work relatively safely with ESD-sensitive parts without a wrist strap and an anti-static mat, but you may not notice my touching grounded surfaces to discharge stating charge before touching the parts, or my holding a finger in contact with the shroud of the USB connector while inserting the driver modules (
in lieu of a grounded wrist strap), or my avoiding setting down the unpacked drivers on surfaces prone to static charge buildup. Someone else plugging a RAMPS and some Pololu drivers may end up with a fried Arduino or driver despite, superficially, doing the exact same thing that I did.
Nobody expressed this idea better than the author of this parable (attributed to Tom Knight). For context, a "LISP Machine" is a type of computer from the 70s (developed at MIT's AI Lab), and Knight is one of its inventors.
A novice was trying to fix a broken Lisp machine by turning the power off and on.
Knight, seeing what the student was doing, spoke sternly: "You cannot fix a machine by just power-cycling it with no understanding of what is going wrong."
Knight turned the machine off and on.
The machine worked.
