I got it to work using NC-Link software.

As far as the code, I used MasterCam and downloaded the DynaMyte...

It's Steve BTW;-)
Busy with new job, kids activities. I burned up one of my drives (DM2800) trying to get my 4th axis working. Bought a Gecko drive setup but no time to play with that either.
If I...

I started about where you're at, got my DM 2800 to read code. It's unique, takes 900 lines at a time. Whatever CAM you're using, find a post processor. They were quite common and easily available as...

Just finished welding my stand for the Dyna Myte. Would like to have the holes drilled and fasteners ready before lifting. Manuals I have claim mounting pattern is "in the illustrations." Not there....

Bought a Gecko G540, downloaded Mach 3.

Wired the stepper motor incorrectly, sparks, popping sounds, lots of smoke while I frantically reached for the e-stop!
Besides the drive I need someone who knows how to correctly wire a stepper...

Found this reply on another forum, someone asking the same machine, same question:
"Try to look for Vexta stepping motor from oriental motor.Model number:
PK 296-01A 2.2 ohm 2A."

In the 1980's this was called "adaptive control."

I'm not sure you can get 4130 so hard it can't be turned, however it comes in a wide variety of hardness. Most times it's purchased at the final hardness required then machined. Saves a trip to the...

Over in the Dyna Mechtronics forum I posted a thread about how I was able to communicate using a couple different DNC software programs, one of which was free and very functional. I also used...

Any luck finding a replacement motor? I'm looking for one also, to put on my 4th axis.

Marty,
Thanks for the idea. Looking for specs on the original DM2800 4th axis stepper motor. The driver appears the same as linear axis.

Okuma provides you with a wonderful tool to use for this purpose called the Schedule File .SDF try it out.

There was some confusion in my navigating instructions to the sdf and min files so here are direct links:

sitting here but determined to get it working unless I can find one for the 2800.
I know it's been over a year but the wife thinks kids activities ALWAYS come first.

Good explaination by BlueChip, I'll offer my own insight.
Like he said, G92 updates the absolute position register. I've used it two ways:
1. Program stop, manual move to program zero, press cycle...

4 axis programming on an Okuma is a seperate issue.
It's been about 20 years since I did it, so forgive if I'm not 100% correct in my response, but I programmed several 4 axis lathes to run a...

I programmed an Okuma to run 79 different part numbers by having the operator enter the quantity of each part into the variable table and pressing cycle start.
You can achieve this through a single...

I'm just trying to give you as much as I can remember, you are determined and the information may help. I make no assumptions on your prior knowledge.

If you can get a look at the transformer on the machine you will see it has different taps for various voltages in the markets the machine was made for. The taps are terminals where you hook up the...

When steel is cold formed and / or Quenched & Tempered essentially the same thing happens: the microstrucure is disrupted and if you could see it at the atomic level there is displacement within the...

step-up transformer.
seams like an odd voltage if you can't find one you could always make your own by rewinding one. There's a bunch of DIY articles on the web for this.

Couple more thoughts:
The breakout box will help immensely by letting you see the signal passing thru via the LED's. That's one reason I like hardware handshaking, you can see the RTS/CTS signal on...

swe,
carefull with that shaking I got solder in my eye once & it's not pleasant. Keep the safety glasses on.
I use a de-solderring bulb, it's got a bulb you squeeze & let go to suck the molten...

cnc_swe,
You can use paramters as listed in your book, just verify DNC software is set the same.
On your program the % can be deleted, should not hurt, but i would delete the blank block between...

It's been about 20 years since I made a cable for a "0" but if memory serves you only need 5 wires (actually 1,2,&3 will do if you don't need handshaking for drip feeding large programs). Get an...

I use a shop vac with my bench mill frequently. Beats blowing chips & coolant all over the shop. First saw this done cutting graphite electrodes, operator duct-taped the nozzle to the head to catch...

I have access to Mastercam, if you want some detail on how I modified the post I believe I had it in another thread here. You need to make sure the first few lines of the program match with what the...

Göran,
I have a DM2800 running on original electronics. It works fine and has some unique features that you lose when converting. If you're lucky enough to have an original touch probe you can set...

Nice looking fixture.

Maybe you could put a few more screws thru it in the center to hold it down to the flat piece underneath. If it's not flat build up the low spots with teflon tape (or duct...
