BiSlide® Linear Stage Troubleshooting Guide
BiSlide Stage Troubleshooting
First - always read the Users Manual.
| Symptom | Possible Cause | Possible Fixes |
|---|---|---|
| The carriage binds or will not move. | During mounting, the base may have been over-tightened or mounted to an irregular surface. This can distort the assembly, causing carriage binding. | Loosen screws and re-tighten to the proper torque. |
| Tighten bolts in cleats to 95 in-lbs. | ||
| Remount base to a flat surface. (Recommend: Mounting surface should be steel or aluminum and have 1/4-20 UNC threaded holes with a minimum thread depth of 0.30".) | ||
| Mounting non-flat plate or blocks to the carriage to hold the load can also distort the assembly, causing carriage binding. Anything attached to the assembly must be mounted flat to the carriage. | Use the "finger test" to check for binding. Grasp the lead screw on either side of the carriage and twist. If the lead screw can't be moved, the slide or the load may not be mounted properly or the mounting bolts are too tight. (CAUTION: Over tightening will increase friction, could stall the motor and cause increased wear.) | |
| There is some backlash in the carriage on a motorized BiiSlide. | Some backlash maybe seen when the lead screw and carriage start to wear. | Adjust by tightening the Allen cap screw on the top of the drive nut. (CAUTION: Over tightening will increase friction, could stall the motor and cause increased wear.) |
| Use the "finger test" to check for binding. Grasp the lead screw on either side of the carriage and twist. If the lead screw can't be moved, the slide or the load may not be mounted properly or the mounting bolts are too tight. | ||
| There appears to be free-play on a motorized BiSlide. This may be accompanied by a clunking/knocking noise when pulling up and down on the corners of the carriage. | Objectionable play can be reduced by tightening the four carriage fit bolts on the carriage surface. | Adjust each bolt equally a maximum of 1/8 of a turn. (CAUTION: Over tightening will increase friction, could stall the motor and cause increased wear.) |
| Carriage appears to be at a slight angle and out of parallel with the base. | ||
| The limit switches are failing. | An out of parallel carriage may angle the limit switch actuator cam to be either too high or low resulting in limit switch failure. | |
| The carriage seems to clunk when pulling and pushing on one diagonal of the carriage. | The Carriage Fit Bolts may not have been tightened equal. | Back off on slightly on the adjustment bolts on the opposite diagonal and re-tighten all 4 bolts equally to 1/8 maximum turn. Use a level and check for parallelism to the base. (See User's Manual.) |
