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

Thats alright i think i am going to go with the driver style any ways , this is just too much of a headache and like you said to hard to debug since if one thing goes wrong the whole thing is pooched. so is the driver i linked going to be good for my application ? is one 24v powersupply enough to power all of these drivers or should i order another ? is there anything else other than a bob and the drivers that i need to get going ?

if i did go for drivers would these be good enough to power my nema 23 steppers? http://www.banggood.com/TB6600-Upgraded-Version-32-Segments-4A-42V-5786-Stepper-Motor-Driver-p-981997.html?rmmds=cart

Here is another video showing you the acceleration it seems the faster i set the motors the less it wants to clunk .  https://www.youtube.com/watch?v=yi7arF9Qers

i will also add the g code. 400 steps per mm yes the board is set to max current.

I went up if anything it helps the slightest but still not happy ,, might be time to go for 4 motor drivers and a bob instead of this all in 1

It would appear I was using 24v and my power supply only goes up to 27.4 should I go up or down ?

will stepping up to 24 v change any characteristic of the motors ? such as speed? temperature? steps per inch ?

I have watched the setup videos to no avail. i have spent hours trying to get the motors to work as smoothly as possible do you think the voltage could be a problem? i am running 4 motors off of only 12v ... the board i have says its good for 12-36, i have no other ideas,,, this is not my first build so i have been through the process before and have had a very smooth running cnc the only diffrence in my new one is its bigger and is 4 axis running 4 motors instead of my old 3 axis running 3.

Thanks for that advice i will continue to investigate
