+ | ====== Leica DM2000 & DM2500 Left-Hand Z-Drive Installation Procedure ====== | ||
+ | The procedure below outlines the steps necessary to install the ASI Microscope Focus Controller Drive onto the Leica DM 2000/2500 microscope | ||
+ | |||
+ | == To perform the following steps, you will need the following tools: == | ||
+ | |||
+ | 1.5mm 1/16, 3/32 5/64 and 7/64 inch Allen hex wrenches | ||
+ | The Allen hex wrenches are provided by ASI | ||
+ | |||
+ | == The procedure has three parts: == | ||
+ | |||
+ | |||
+ | - Removing the left fine focus knob & Installing the helical coupler | ||
+ | - Installing the Baseplate & Installing and aligning the motor drive assembly. | ||
+ | - Installing the motor drive cover plate and fine focus knob. | ||
+ | |||
+ | ===== Part 1 - Removing the Left Fine Focus Knob ===== | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | a) The DM2000 & 2500 have a magnetic attachment to a steel inner knob | ||
+ | b) Use 1.5 mm Allen wrench to loosen setscrew to remove knob. | ||
+ | c) Pull knob straight off to expose shaft – Do not twist | ||

+ | |||
+ | d) Locate the ASI Z drive and use the 2 mm Allen wrench to remove the helical flex coupler off of it. Note as shown the coupler will have a notch machined out of one side. The notch is designed to slide over the tab that is on the white inner gear as shown. | ||
+ | |||
+ | ===== Part 2 - Installing the Baseplate & Installing and Aligning the Motor Drive ===== | ||
+ | |||

+ | |||
+ | |||
+ | a) Locate the ASI fine focus motor drive and loosen the two vertical adjustment screws that secure the drive to the adjustment bar. (See figure 3 for location of the two vertical adjustment screws.) | ||
+ | |||
+ | b) Locate the base plate, and if the Z-drive is attached to it as shown in figure 4, use the 7/64” Allen wrench to remove the horizontal adjustment screw that secures it to the base plate. | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | c) Lift the front of the microscope up and slide the baseplate under the microscope so that the unit is centered under the left focus knob as shown in figure 5. | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | d) Locate the ASI fine focus motor drive and align the drive shaft on the ASI drive with the helical coupler as shown in figure 6. Slide the motor drive shaft into the hole on the helical coupler as shown. Use the 7/64” Allen wrench to loosely tighten the horizontal adjustment screw to hold the drive in place as shown in figure 7. Please note that the base plate may need to be moved slightly to align it properly. | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | e) Use the 2 mm wrench to securely tighten the couple onto the fine focus shaft of the ASI Z drive as shown in figure 8. Use the 7/64” Allen wrench to loosely tighten the vertical adjustment screws as shown in figure 9. Please note that the coupler must be securely tightened to prevent slippage | ||
+ | |||
+ | f) Test the alignment of the Z-drive by turning the right fine focus knob. There should be no point within the 360 degree movement of the knob where any binding or drag is felt. If any drag is felt loosen the vertical & horizontal adjustment screws and side the motor drive up and down, forward and backward slightly while turning the right fine focus knob until it is in the position where minimum drag is felt on the right focus knob. Secure the motor drive into position by tightening the horizontal and vertical adjustment screws. | ||
+ | |||
+ | [{{ :: | ||
+ | |||
+ | g) Using the 5/64 inch Allen wrench tighten the base plate set screw as shown in figure 10. Recheck the alignment in step f, above, by noting the drag on the right fine focus knob. No noticeable drag should be felt. Repeat the above steps, if necessary. | ||
+ | |||
+ | ===== Part 4 - Installing the Motor Drive Cover Plate and Fine Focus Knob ===== | ||
+ | |||
+ | |||
+ | [{{ :: | ||

+ | [{{ :: | ||
+ | |||
+ | |||
+ | a) Locate the motor drive cover. | ||
+ | |||
+ | b) Slide the microscope fine focus knob, that was removed in figure 1, over the shaft extension and secure it in place by tightening the setscrew loosened in figure 1. | ||
+ | |||
+ | This completes the procedure for installing the ASI focus drive on to the Leica DM 2000 to DM2500 | ||
