I noticed in the firmware report (M503) that I got:
Recv: echo:; Backlash compensation:
Recv: echo: M425 F0.00 X0.00 Y0.00 Z0.00 S3.00
Then I saw this video: LulzBot’s X/Y/Z Backlash Compensation for Printed Part Accuracy - YouTube
I am not near the printer at the moment, but I don’t remember seeing that cube on the printer.
Is there a way to add the cube?
(I am also wondering it will help with the ringing issue I have on the 747).
It would take substantial modification to add something like automatic backlash compensation to the SideKick as it does not use conductive leveling like the Workhorse or Pro.
Backlash compensation is enabled in firmware and you can definitely adjust these settings via your printers LCD if needed.
Configurations → Advance → Backlash.

Thanks @McLeach. I’ll have to get one of those devices (edit: dial indicator) to measure if it is necessary. On second thought, I don’t think it will help with the problem I have with ringing, but it may help with dimensional accuracy.
On the ringing, I wonder if that can be open loop compensated via an intelligent slicer (that probably does not yet exist). E.g. since ringing is fairly consistent from one print to the next, it seems that the gcode could be modified directly after appropriate measurements are taken.
Another thing you could try is a “backlash tower” print. It’s a specially made print that is a square tower with ribs, and you can look at where the ribs are closest to be flush with the surface to see what the best backlash setting should be for X and Y. You could then enter those values with the M codes and save the settings.
And that basically sums up all I know about it. 
I’ve not tried it myself so I don’t know how effective or accurate it is, but it might be worth exploring if you are concerned about backlash.
But on the other hand, I’ve been amazed at how well the Mini 2 and Sidekicks can print without the auto calibration cube. And I don’t think ringing problems will be cured with backlash compensation.
Thanks for the tip.
I agree on the ringing, but I do think it could be fixed in firmware open loop based on measured and entered parameters. I could be wrong…I’m a newb still.
