wes709,

I would suggest you do some reading before you buy any piece of Chinese junk
problematic unsupported drive. Others may have a different opinion on them!

Go to the Gecko site and read the support info:
http://www.geckodrive.com/support.html/

Maybe consider this drive:

Till then,

RICH

+1 on Gecko.

It hurts to have to buy something twice. Think how bad it will sting if you have to buy this stuff again for the third time!!!!

If you can afford it, buy name brand stuff that is going to work for the next 20 years and still have resale value when you sell the machine.

I had a mill that came with a 4 drives on one board. It ran the mill but upgrading to Geckos really woke up the machine. I went from 10ipm rapids to 150ipm in testing and I turned it down to 50 ipm IIRC in actual use just to not wear out the machine ways.

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.

I have looked at the g540 and I do like it but I think I will stick to the drivers and Bob because I would eventually like to add a 5th motor possibly for a extruder :) I realize Chinese stuff is junk but the all in 1 board that I'm replacing was 45 dollars and the bob and 5 single axis drivers was 85 so I'm 130 deep still not half of what the g540 is worth and if this fails looks like I'll be buying a gecko and then it will sting , keep in mind I am very young and don't have alot of money for this stuff

I understand not having the money to do it right. What I am trying to do is tell you what I have learned from my experience. If you could have spent the money on good stuff up front, all the time you have spent fiddling with drivers could have been spent running the machine.

That being said sometimes you need to experience certain things for yourself.
Welcome to the life long addiction, I mean hobby of CNC.

Those TB6600 drives you linked to are OK. The good thing about separate drives, is you can replace/upgrade relatively easily in future.

I've got a couple of those TB6600 drives on the desk for when I get around to retrofitting an engraving machine, and from the research I done, they're a major improvement over the older all in one TB6560 boards. The main thing is make sure you're not pushing them too near their limits.

The big killer of the older chips was people running them pretty much on their voltage limit, along with often poor board design, meant a slight voltage spike took them overvoltage frying them, or they simply overheated.

We have all been there and understand. So enjoy what you are doing with what you have.  :)

A user, such as mc, may have an "identical" driver and can help you out.

Good Luck,

RICH

wes709,
Didn't look at the links.
Just check the resistance ( inductance if you can) of each phase wiring of the stepper. The values should be close for each.
Test if there is conductivity of the phase also to ground ( unlikely since  if there was you would probably blow the drive).

Also check that the is "no" conductivity between phases.

That looks like a wiper motor from a car? There should be a connection for the motor - this will have resistance, and also a connection for a 'park' switch - this will be open or closed depending where the motor stopped.

They are useful motors.

Hey There my B.O.B and drivers have finally arrived! However hooking them up is proving to be harder than i expected... any advice? i have this video as always to show you where i am at.
