Stiffining the X axis

[ken]

Hi Derek,

I came up with this mod.

I took the angle brackets which are optional for the bottom front of the Y rails and mounted them on the Y gantry plates and the bottom X rail. I simply filed off the slot tabs on the gantry plate side of the brackets instead of drilling pockets for them.

My test for this was to compare the amount of force it would take to deflect either plate while holding the other one against the front frame. I had removed the Y axis lead screws for this.

The stiffness improvement is dramatic.

The one thing I am not sure of is with both lead screws installed , how well the 2 Y steppers maintain track. Maybe this would help them to stay in sync.

Hi Ken,

Glad you got some good use out of those brackets. Nice work and thanks for sharing.

The two steppers will maintain track well. I recommend checking square every once in a blue moon since there is nothing that mechanically links them, but with all the CKs in the field we've not seen an issue there.
