Here is my take on a Y axis stiffing mod. this mod is easily reversible and removable.
Parts you will need:
T-Slot drop in nuts (20 series) at least 10 - the more you have the better
Screws to match the nuts. - these dont need to be very long (5mm should do . but measure twice i had to get washers)
1 8ft pice of 2x2 Al angle iron from lowes cut to exact length.
Measure, cut, drill, screw, enjoy
this instantly made a massive difference with Y movement. even testing movement by hand, you could tell a difference.
Thanks for posting this. I will be ordering an X-Carve in the next few weeks and this modification option had occurred to me. Wasn’t sure this could be done without interfering with the carriage. Thanks to you, I see that it can. Was considering using aluminum plate and a cover of thin plexi or masonite in lieu of the wasteboard along with the angle stiffening.
