Motorized lift for the OPTIdrill DX15V

thingiverse

The Optimum OPTIdrill DX15V is a very nice (albeit expensive) machine. However I did not like the hand crank for moving its table up and down. What I found most annoying is that there has to be enough free space below and behind the machine to operate it. So I designed a motorized lift. The motor attachment has a very small profile, so the requirements for free space around the machine is almost neglectable. Have a look here to get a first impression of using the lift: https://www.youtube.com/watch?v=uyh9xmv3XeM You need to print one part from each of the 6 stl files. I have used two different settings for printing: - 0.2mm layer height: motorcase, switchmount - variable layer height (0.12...0.25mm) for all other parts Additional parts: - Gear motor 40GZ495 24V 50RPM (e.g. from ebay) - a connector 12mm/8mm for connecting the motor shaft (8mm) and the shaft on the machine (12mm), you might need to use different length of set screws than the ones supplied with the connector - Power supply 24V 1A - Momentary switch 2xon-off-on for a hole size of 28x22mm (e.g. from ebay) - Machine screw M6x25mm + washer + nut for mounting the assembly to the table - 15pcs M4 x 6mm ISO7830 screws for connecting the motor and all of the printed parts - 2pcs M3 x >=10mm ISO7830 screws for mounting the strain relief clip The most problematic part might be to drill the hole at the machine table at the correct location. I suggest to at first mark the location of the printed parts on the table. Then remove the motor and use the diagonal pilot hole in the printed parts for marking the location to drill on the machine. You might want to use a 7mm drill to provide some wiggle room for later mounting the assembly. OpenSCAD source code included. If you consider varying the design: The motor I have chosen is working at its limit nwhen moving the table upwards. So maybe you can find a motor with a bit more power. Another option is to use a 35RPM motor. I did use a 12V 35RPM model on the first attempt. It was slightly more powerful, but also too slow in my opinion. On the photos you can see another design from me for the DX15V: A precise depth gauge. If you are interested in the design files and want me to upload them to Thingiverse then please let me know in the comments. <b>Happy printing! - And then please post a Make! Thank you very much!</b>
