Is there a better way to get dimensionally accurate prints out of a delta printer?

You are out of luck with that budget.Quote

Max budget would be around $50

From the technical point of view, a proper calibration does not need 32 bit electronics. One can do it with an 8-bit firmware controlled over USB. But nobody bothered.

I think I may have been a bit unclear with my long description. Marlin's delta auto calibration finds tower angle offsets and delta radius (and some other corrections). However the delta diagonal rod length is something I enter in the config.h file and it stays fixed - it's not affected by calibration.

Can you suggest a suitable control board that will run the firmware you recommend? Max budget would be around $50 because I already spent quite a bit upgrading the drivers to TMC2208s.

I'm sorry to be negative, but RepRapFirmware running on 32-bit electronics solved the problem of calibrating well-built delta printers three and a half years ago. It seems that other firmwares still haven't caught up;

What I'm doing is printing the hexagon and measuring its sides. Then I plug those measurements into the spreadsheet ...
