Originally the splash guards had an angled bottom that funneled the coolant and chips back into the plinth and down into the coolant tank. Since this section didn't extend all the way to the front, I...
I removed the existing back splash panels and trimmed the clear shower curtain to fit the contours of the column and base. I then used a couple of magnets to hold it in place.
...
So needing something quick and inexpensive, not to mention something I could finish on a Saturday, I designed a shower curtain enclosure for the machine. There was already four threaded holes on the...
After tuning the Bardac spindle driver and setting the home and soft limits in Mach3 I was ready to make some chips.
However, the little table surround was hardly up to the task of keeping...
As soon as the Gecko G540 arrived, I went to work installing it. I started with a sheet of 1/8" aluminum bolted to the inside of the cabinet and fastened all the components to it. I reused the power...
Wow, you've been busy!
Good work. The lathe looks like it came off the showroom floor.
Is the spindle 100% manual control?
Timothy
The original spindle driver required 460vac 3 phase input through a very large transformer on the back of the machine.
The Bardac is a 240vac single phase input, so other than a large breaker at the...
A trip to HGR Industrial Surplus in Clevland provided me with the computer cabinet I needed and a stack light.

The spindle driver was next and after a bit of online research I decided to go with a Bardac 3200i DC driver. It takes +-10v singals and has tach generator input too. Luck would have it and I found...
First thing on the list of things to do was to decide what electronics I would need to complete the retro fit.
After an email to Marcus at Gecko Drive, the original steppers would work perfectly...
I connected 240 single phase to the machine bypassing the three phase needed to drive the spindle and fired up the control and the steppers. Everything was in order, the table and the head moved and...
Not a chance Preben. No post processor will spit out Dynalan.
Retrofit it with Mach3 or any other controller and run standard G code.

After the long drive and the 4am drop off (had to get the truck back to the yard by 8) I spent the next day getting the machine in position and leveling it out.
This was actually my second DM4400....
And what pretty pictures they are....
Better than mine. Maybe I should buy a new camera. :violin:
Anyway, when you take everything apart you'll find that the Portescap stepper motor wiring color...
Now that the Dyna Mechtronics section has been added to CNCZone, I can post the retrofit/rebuild of my second DM4400.
We'll start off with a picture of the machine from the ad I found online.
...
Are the steppers 160 oz/in Portsecap motors? If they are then they are the same ones that are on the DM4400 mills.
Timothy
I forgot to ask... what size of spindle motor is on the 3000?
Timothy
Right on! Thanks.
Timothy
Was that the Dyna Myte 3000 that was on eBay a few days ago?
I was looking at that one but the drive was just too far.
Timothy
This should work.

Gecko Drives will ship directly to Canada.
Timothy
Yea, thats what I was thinking.
No need to make it more complicated than it has to be.
I'll go dig though my electronic spares and see what I find.
Timothy
Would it be advisable to add a relay in the e-stop circuit on the G540?
I'd like to use the e-stop position to operate a relay that switches on a stack light on the top of my VMC.
Or should I...
You can try MotionTek. They are in Scarborough.

Any updates?
Very, very nice. I like it Tim, good job.
Coolant enclosures aren't something you see alot of on smaller machines. Guess it depends on your style of machining. I myself, like the fire hose...
Hi Dan,
I know how you feel. I have a Dyna Mectronics DM4400 retro fitted with a Gecko G540 but still using the original 160oz steppers. I lose steps during heavy cuts on a regular basis and re...
You can get the drawing of the pull stud from the Dyna Mech group on yahoo. Look in the file section after signing in.

Hey Willy,
Did you get the VFD figured out and running?
Timothy
Well, sort of.
You would have to disassemble the whole machine so you could turn the plinth (base) on its side to slide it through the door. However, its really heavy, somewhere in the...
