Hi All,
Another chapter in this epic 3040 journey!! :D
Started a nice dimensional file last Friday and got about 75% through it when, whammy! Strange noises and devastating cross cuts destroyed what was shaping up into a beautiful piece.
Wellllllll, my Z output has some problems - After about 250k lines of code towards the end (also the first on the machine) my Z motor started chattering and seemed stuck in place, then quit moving entirely, but still let me know it was trying by the guttural groan it kept putting out.
So, I've tested for the following and come up with this:
1) All motors good - tested all three.
2) Mach3 Pins and ports good - they remain at the settings that worked initially.
3) Spindle good.
4) Get same chatter and non-movement when I hook the z cable up to any motor.
Any thoughts folks?

Reduce the Velocity and accel and see if that helps.

no luck....
-
How much did you reduce them by? Try reducing the accel by 50%.
-
roger that - reduced accel 50% to 50 - no luck.
settings that previous worked are
steps 400
velo 700
accel 100

Bad drive or cable
-
ok. does a bad drive mean a component in the control box or the motor?
-
It is not going to be the motor if it works fine from another axis, so it will be whatever is in your control box that drives that motor. Do you know what is in the control box?

it's a 3040 3 axis T-D
-
afraid that means absolutely nothing to me, if you can provide a link to documentation I can have a look to see what you have but I am not even going to attempt to do a search as I fear I will spend many hours and get nowhere.

Thanks Hood - realized that's what you meant about an hour ago - ...was rushed this morning on a few projects.
I'll pull what I can and send it along.
Thanks again for your help.

Good Afternoon everyone from snowy washington dc.
Can anyone recommend where I can by a new controller box and cables for one of the world famous chinese 3040t routers.
Mine is kaput, and, being well out of my technical range to fix, I'm looking for a new controller and cables to simply swap the whole thing out and get on with the projects that have been on hold for over 30 days now as I've waded through this. I'm running a licensed Mach3 program a windows platform. I'm asking for cables as I understand that shielding may be an issue and might as well address that now as well.
Not looking to replace it with the same controller - rather something some of you fine experts might recommend.
I'm running intricate dimensional artcam files.
If any one has a used unit they would like to get rid of that works fine, I'm more than happy to look at it.
Thanks Everyone,
Joe

Joe,
The Gecko G540 would be hard to better http://www.geckodrive.com/geckodrive-step-motor-drives/g540.html plus their site contains all the necessary data / information to get it up and running etc.
Tweakie.

I bought a g540 controller before even plugging in my machine. I still have the stock blue box controller it came with, never used. PM me if interested. By the way, I have read that the stock controllers are problematic, but have read equally that people fire them up and start cutting with no problems at all. Typical low budget quality control I think. Some are good, and some are not so good, and it dont matter because they all cost the same! I didnt want to risk having to diagnose mysterious problems, thats why I went g540 right off the bat. It was a good decision.
