Re: Worm Drive Grounded Delta Printer
@ A2 Thanks for the offer on the abs. 20. Can you explain your reason for thinking equal length arms will stop the zig zag problem? Mathematically the two arm lengths are included in the formulas as...

20. I don't know that different arm lengths will effect the Z axis position, I hope not. But I wonder if the precision of the variable calculation (single, double, float), and the ratio of the arms...
