Fastest1,
Tried to PM you. Box full. Can you look at Dyna mech forum. Question there you can probably answer.
Thanks and sorry I derailed this post.

Hopefully someone who has done this mod will respond? Fastest1, Cole, Cyclone, Birt?
What modification has to be done to the backlash nuts in order to mount a Nema 23 directly to the lead screw?...

What steps and parts will I need to replace the DM2400 stock motor with a new 23 stepper?
I know i'll need a motor mount to move the motor over so I can make it direct drive. How do I connect the...

I thought that might be the case but thanks for verifying.

I have a DM2400 that I have run with Mach3 on Chinese BOB and drivers using the existing spindle control and the 24v onboard power. It was easy enough once you understand all the terms and how they...

Is there a way to view pictures on old threads?
Thanks

The PM request was just 3 days ago and the thread was dead for 2 1/2 years until I just started it again when you jumped in. But whatever.

Its not cool to Highjack threads.

I have looked at the retro's and have asked some of the people that have done them, about the motor mount. I'm wondering if they have made a plate to attach to the existing motor and electronics...

I know this is an old thread but do you still have the mounts and couplers? We spoke before and at the time you weren't sure if you still had them.
PM with details if you still have. Any chance you...

Cracked a 100 tooth screw gear today on my dyna 2400 and could use a couple spares, if anyone has extras left over from a retro fit.
Thanks

I crashed my Dyna 2400 today and broke the Z axis 100 tooth gear. Has anybody done a retro fit and have a couple spares they would give up? PM if you do.
Thanks

Here is my hardware;
Old Meistergram engraving machine built like a tank.
Old Dell running WinXP
Vexta PH268-21, 5V, 1.5A, 1.8*, 125 Oz torque. Used on X and Y.
Sain Smart TB6560 BOB, ST330 Motor...

I don't see the PICS.
My machine is a very early model and I do not have any reason to believe that it was included as part of the machine. No mounting holes and none of the wiring was cut or...

Isolation transformer?
Fast,
I was looking at the pics again. On a video by smoothstepper he spoke of an early model DM2400 with the isolation transformer on the inside of the cabinet that...

So I gutted the control box and removed all the old wiring I'm not using and started the refit. I have been looking at pictures of other machines and discovered a number of pictures that have a piggy...

I reread this and it wasn't clear. Obviously the set screw would have to be tight enough to engage the shaft. What I meant was the set screw would contact shaft only enough to allow it to shear in...

I am working on the electronics cabinet on my Dyna and found an issue with the power switch. It is barely held in by a small brass screw that will not last very long under use. The switch is an EAO...

Tonight I removed the motor cover off the Z Axis to pull the drive card off and put new JTS connectors on in prep for the Gecko drive. Here is what I found, When I turned the motor shaft it turned...

I have the G540 already and I am playing around with relays on an Arduino project I'm working on too. Spindle works fine now with new potentiometer, so I think I'll stick with the manual spindle for...

Old I know!! What is a PP/LPT?

FAST,
I thought you had responded previously regarding this conversion and I tried to PM you but your inbox was full.
When you say manual spindle control, I don't need any additional components to...

Can I get a Dyna 2400 running using the existing Spindle control(manual), and nothing more than a Gecko G540.

I have invested more than practical on this machine and don't really want to put a...

Do you still have the probe?

Thank you for the reply and part numbers, that is exactly what I suspected. I will call JST. Did you leave the spindle control board in or did you remove it?
When you say rewire do you mean new wire...

I'm starting an upgrade on a Dyna DM2400. The plan is to use existing power supply and motors with a Gecko 540 board. I want to ask the successful upgraders if they rewired to the motors or did you...

When using the DM2400 in manual mode, spindle switch on, and selector knob on zero, should the spindle be turning at all, or should it be stopped?
I had a bad on off switch on the spindle that I...

I will take your comments into consideration and look at your further recommendations. Thank you for your help. You are the first person to provide what I see as good solid information with the...

Thank you Ian and I'm sorry about the melt down regarding the word processing. I have been on a number of forums and this is the first time I encountered as many problems typing as I have on this...

I was having trouble with the text selection and the word processing on new threads and had a melt down.

Anyway, I have built an engraver , for garage use, and used what I could find for hardware....
