HAAS TM-1 TIP: How To Remove The Red Handles For Improved Axis Acceleration and Motion

DISCLAIMER

The following info are changes that were made to our equipment and for our reference only. Do not attempt to make any changes to your equipment. Only certified technicians with the proper skills are permitted to make changes to equipment.

The HAAS TM1 (or HAAS TM-1P) came with large aluminum handles attached to the X and Y ballscrews, intended to be used by hand. I thought these would be useful, but in reality they are not. The position is awkward, which makes using them difficult. Their large diameter means that they require more energy to accelerate and decelerate than the ballscrew itself. This limits the acceleration and deceleration speeds.

The red handles can't simply be removed from the HAAS TM-1, because the servo motor controllers were tuned with the handles attached. Removing them without retuning the servo motor controllers will cause the motors to oscillate, and will result in underdamped motion.
