are you using mach3? if so it only needs 1 pulse per rev. There are instructions in the manual. I have a small optical sensor and a tab that breaks the beam.

Hi will gilmore,
Thanks for your reply.

No problem. Your project is looking great. Let me know if you have further questions.

hello monkeyking,
what are the updates on you lathe?
did you tried a parting tool on your lathe yet?
I am having troubles with a parting tool on my lathe to cut 1inch dia of cold rolled steel. It makes a lot of chatter and noise and at last the spindle stops.
i kept the feed rate to 0.0005 inch per rotation. still it makes chatter.

looking forward for your results,

Hi jasminder,
My parting tools cut perfectly on my lathe.
I use S1500 and F15 (all in metric), plunge method.
For your case, parting tools should be a bit lower than centre of lathe.
And you said spindle stops, seems that the motor not enough power for me.

1500rpms?

do the tool makes any noise?
any new videos of full lathe?

Hi jasminder,
My parting tools made from carbide,
No noise come out when I do parting.

My Z axis out of precision as much as 0.02mm for 120mm
My X axis out of precision as much as 0.07mm for 180mm

.0028"/7" is alot of misalignment in my opinion. That should be looked at and corrected. You don't always hit a home run when building your own tools, either in correct design or machining of the parts. Being able to measure and correct the tool is the real deal.

Fantastic work, your lathe looks great. I hope you can share a video of it in action sometime. :banana:

Just curious - have you posted any pictures showing the gang tooling set up on the lathe?

That flimsy weldment frame probably twisted itself apart, and he's too embarassed to post any further pics.
