Test run went well on Saturday. Finished the base too with t mounts. Will send a pic soon. Initial run at 26ipm jammed the steppers. Had to drop it down to 10ipm to get it to run. Adjusted the stepper mounts, loosed the belt tension and dropped the ramp down to .5. Got 50ipm on the Y and 35ipm on the Y. The problem seems to be the stepper mounts. If I loosen the nuts I can get 42 on the Y. Seems to be the alignment of the stepper shaft to the drive screw. Has anyone tried a small universal joint.
Cut a test piece at 1/8" pass' with an old bit and it was perfect for dimension but did a lot of burning. Got some bits today and figured I'd machine the housing/carriage for the dampers. Will send a pic of them too and plans if anyone wants them.
That work bench table in the pics is not the machine base. An old bakery top I salvaged and converted to a work bench. Drive and motors are from Xylotex. |
