Title: New toy - DM3000 lathe
Post by: Jeff_Birt on May 06, 2013, 08:29:21 PM
I was able to pick this up from a local school auction. It has not had a lot of use but has been sitting for years. It is going to get a good cleaning and conversion to Mach3.

Hi Jeff,
Looks like you picked up a nice addition. I have the DM300H version that I am in the process of converting to Mach3 as well.

It looks like it is a conversion of one of the chinese mini lathes like Harbor Freight etc.  Little Machine Shop carries every part of those lathes.

The DM3000 is not a converted Chinese lathe. Dyna Mechtronics designed and built these back in the late 1980s. It is built like a tank, I'm guessing it weights about 500 pounds. Dyna still has some parts on the selves for the older machines but not a lot. Mechanically they are very robust but the 25 year old controls and electronics seem silly by todays standards.

The first machine I converted for use with Mach years ago was a DM2400 mill. It is about the size of a Taig but again, built like a tank.

Good find Jeff! Keep us updated and fed with pics along the way.

The first order of business will be to modify the base that came with it to do a better job of clearing the stupid drain spigot on the bottom of the machine. For some reason the drain fitting hangs down almost 1.5" below the bottom of the machine. I also want to add castors to the base. BTW, I finally found where the weight was listed in the users manual; it weighs 550 pounds.

If you guys ever need to move this type of machine jack up each end and bolt on a 2x4, this will let you slide it around and clear that stupid spigot.

Jeff,

Please keep us posted with pics. I am in the same process with 3000h I recently purchased. I have a few issues already I am trying to get past. Maybe someone here can point me in the correct direction. The 3000h turret uses a 8 wire step motor and my new x/z are 4 wire. I think I can possibly tie particular wires together and control like the others. Or change it out. Also, spindle on mine appears to be a dc servo. Haven't figured out how to control that just yet either.  These are great machines and very rigid for what they are.

Hi Jeff,

Greetings for acquiring this nice little lathe. 550 pounds for a table top machine!! Pretty impressive! What foot print is it? And the chuck diameter? Also wonder if most of the weight is the base or the enclosure and electronics.

Jeff,
You can use your existing driver cards (if this is the type I am thinking)  the orange and brown wire are step and direction, I forgot which is which.  Black and red are the power lines.  I converted one for the high school here back 8 years ago.  Beware of noise from the spindle DC controller board,  I had to put some small caps on the step and direction lines or every time I ran the spindle the machine would move on its own.
