z axis loosing steps

[ptjw7uk]

As Irving said I did change for a more powerful stepper and also changed to parallel drive.
I did try all the options for lower acceleration but they all made no difference that I could detect.
I may in the future try and balance the head but at the moment I am thinking more in the way off removing some of the flex in the column, I am also trying to work out the options of changeing the way the Y-axis works by siting the stepper to the rear and fixing in place instead of moving with the Y-axis. aka KX1.
My biggest headache with the rear siting is the head tilting mechanism I may get rid if it altogether and make a new support for the Z-axis arm, just need a great lump of metal!

No real substitute for a great lump of metal :naughty:

...but I am seriously considering filling my round column with concrete.

Rather a lot of concrete reinforcement bars have mysteriously appeared on my steel racks, probably enough to fill it. Hey, it was cheap :heehee:

Wonder what the optimum concrete to iron ratio would be for stiffening a round colum :whistling:
