Improving the mini lathe cross-slide

Adding rolled bearings for smoother operation. Optionally adding a NEMA 17 stepper motor.
No motor: www.thingivers...
With motor: www.thingivers...
Bearings: 608 on the front and 688 on the back. Exact models I used (but other should also work): 608-2RS and 688ZZ.

Very clever and thank you for taking the time to record, edit and share your work with those of us who appreciate your efforts to spread the knowledge. Cheers brother

[@fatblokeonamotorbike1600]

Maxim you're a genius! That's exactly what I was looking for and just needs a geared Nema 17 - after all a cross slide only needs to move slowly. Personally I'd like to keep the scale on the handle, and be able to disengage the gear to use the handle manually without winding the motor, but these would be simple developments of a brilliantly simple design. Excellent engineering.

[@MrTjmk]

I never thought about 3D printing the parts needed to add bearings. I'm glad I got a chance to view this video. Now I can smooth out the cross-slide on my Mini Lathe.

[@icebluscorpion]

How do you compensate the huge inertia of the wheel and handle? Wouldn't it be better if it would be driven directly with a planetary gear? I mean what for a improvement is that with the handle still on? I mean if I would have a lathe and I would upgrade it to a cnc lathe then personally I wouldn't need the handles anymore. I would load my G code in the cnc lathe and just supervise it. Anyhow great work. Keep it up!

[@MaximKachurovskiy]

Thank you. I was turning a part last night and used both ELS and the handles, was fun. Jumping through CNC hoops is only sometimes worth it in the home shop.

[@icebluscorpion]

How does it work? Do you need to stop the ELS how does the cnc system know were to start again when you are finished using handles? I have a CNC 1830 the only modifications that I made are the end stops a beefed up Z carrier and a 800W 30000RPM spindle. I use Grbl and F360. I noticed that I can also can generate tool paths for cnc lathe in Fusion. And Grbl could be set as lathe as well. Do you have a homing and stops and a homing routine for your CNC lathe?

[@MaximKachurovskiy]

Jack, yes, I'm using 30 degree on the top slide. Reason I did this is to have more control when trying to take off the last hundreds of a mm. My cutter is still parallel to the chuck as much as possible. Not sure if this is the best setup though, just too lazy to rotate it now :)

@@MaximKachurovskiy I had good luck with PETG on Isopropyl cleaned PEI until one day it would not release from the PEI and ruined the surface. Since then I've used a light mist of Aquanet on PEI and never had another problem. I also print TPU and PLA on Aquanet now, and rarely ever need to clean with Isopropyl. Aquanet coatings last quite a few prints, so it is much lower maintenance than PEI alone. It collects some dust but the prints come out fine. Occasionally cleaning with water removes the dust and Aquanet and a new mist is applied. I also avoid touching the surface as finger oil causes a lot of the common adhesion problems. Another misting every few prints is sufficient, and it saves a lot of alcohol. I've not even used a whole can of Aquanet in a couple years, not much is required. I also tried the Windex but Aquanet works better than Windex or Glue Stick.

@@MaximKachurovskiy just done this mod, a friend used his 3d printer to make the part but didnt use full strength. I can feel a small amount of flex but the slide is so smooth now. I will be getting another made soon ( in a better colour) and full strength hopefully.

I wish I could :) But I have no equipment for such a task.
