I made the motor mounts like "Heat Sinks" to help keep the motors cool, don't know if this is necessary, but thought I'd give it a try.
The 180 IPM is jog speed, the motors (oriental motor PK266-E2.0) can run at 2000 RPM (used on X and Y).
I had problems with vibrations in the X ACME screw (~48" long) at high speed, so I made a dampener yesterday (not shown in the above pics) out of UHMW that applies slight pressure on the screw about 2" away from the nylon nut on either side, and it worked great! |
