Re: Recommended Lathe X & Z Axis Inches/Minute

I had completed the X Axis and basic Z Axis about 2 months ago and it's neat that Dan and I had come up with the same or very similar solutions. I had looked into several ways to do the conversion and had finally decided that this way was the simplest way to do it. The ratio will be the same as the ...

Re: Recommended Lathe X & Z Axis Inches/Minute

Thanks guys -
I'll have to get the motor mounts made as my mill is in pieces and will be my next project after the lathe is up and running.

Re: Animatics Smart Motors?

I agree with Marty and you may want to contact Teknic or DMM-TECH and let them know what you have and what they suggest as a replacement.

Re: Recommended Lathe X & Z Axis Inches/Minute

Here are the renderings of the Z Axis assembly. The ClearPath servo mounting plate is new along with the timing belt and pulleys. The timing belt assembly ratio is 3.6:1 with a 20 tooth pulley on the ClearPath and 72 tooth pulley on the lead screw. I laid it out this way so I wouldn't have to modify...

Re: Recommended Lathe X & Z Axis Inches/Minute

Hi Marty, Thanks for posting those photos and I agree, using the existing gears would probably be a problem and at some point would have to be changed out to a timing belt design. I started working on that layout last night and determined that a 4:1 ratio was about the highest ratio you can get and ...

Re: Recommended Lathe X & Z Axis Inches/Minute

Hi Milton, All of the specs I mentioned in the initial post came from either original drawings or the spec sheet for the stepper motor. The Z axis P852-508-B stepper motor spec is attached. The X axis is a much smaller stepper but if I can get the Z axis right then the X axis ClearPath will be easy ...

Recommended Lathe X & Z Axis Inches/Minute

I'm working on the conversion layout of my Dyna Myte DM-3000 and have a question regarding axis movement. What would be the suggested maximum inches/minute for axis that have 2.5mm (0.098")/revolution lead screws? The existing Z axis stepper has a max RPM of 1500 and the lead screw is driven by a 10...

Re: Fried VFD and Acorn

Would you let us know the make and model # of the VFD and a link to where it's purchased?
