Help with wiring of jp-1635a

[darius12]

Please help, i am so much trouble setting up one of mine drivers. I upgraded my diy cnc and i had to buy a driver, i bought the HY-DIV268N, that i could not make it to work. So i assumed it was defective and i bought another one, JP-1635a, but i can not set this up either and i really do not want to buy another one. i have the HY-JK02-M break out board and i use Mach3. I searched and searched for wiring diagrams but i could not find any. If anyone has some information i would be grateful.

A simple search on HY-DIV268N gave me some very simple clear wiring diagrams for all the set up.

I want to set up the JP-1635a driver not the HY-DIV268N driver, on which i said i gave up, after trying every diagram i found. But if you want to be entertained until someone providers me with wiring diagram for the JP-1635a, point me to one of this very simple an clear diagrams and i will try it and provide you with the end result on my rig.

Sorry - I will have to let you do the searches.

OK so i managed to set the wiring correctly, and now all my axes are working, but i am loosing steps, on all axes. I don't know what to troubleshoot.

More details needed about speeds and so on. Many reasons possible.

I have 4 motors in total, 3 NEMA 23 3 NM speed 3000 velocity 1200 and 1 NEMA 17 1NM speed 1000 velocity 500, 3 DM860 drivers and one JP-1635A

Mach3? Mach4? LinuxCNC? UCCNC?
External pulse engine?
BoB?

We need a lot more info before we can help you. You help us, we help you.

Bob is HY-jk02-m and i use mach3. I said these in my first post :P

OK, first step is to halve the acceleration.
If this improves things a bit but not enough, halve it again.
Sometimes steppers just cannot accelerate very fast.

did you add a power supply for the 4th stepper driver or upgrade your existing power supply to power 4 stepper drivers ??

If you are using the original supply to power all 4 stepper drivers that could be the problem

[darius12]

John i have 3 power supplies as the jp-1635a works on max 36V and my other 2 power supplies work on 48V, so i am using a PC power supply on 12V

Roger - halving the acceleration did nothing but lowering the velocity did solve the problem on 2 axes X, Y that use the larger steppers and drivers, on the Z axis it did not work even if i set it to a crawl

[RCaffin]

12 v is really too low. Some drivers won't eve work on 12 V.
I recommend first increasing the supply voltage as high as you can for the drivers.
Then we can tune what we have.

Well i ordered A DQ542MA, i will get it in a week, it has a 50V max input voltage, so i can use my current PSU, i hope it will be the end of my problems

[RCaffin]

if dq542ma is switched mode rather than just a big transformer, you may need to put a stack of ferrite chokes on the lines between. most drivers do NOTT like the high frequency noise coming from such PSs.

So after installed the DQ542MA driver, the Z axis was still missing steps (i tought), so i double checked everything, and i found out that the coupler from the Z axis was sliping

The DQ542MA is a stepper driver, so no transformer, i don't know about my PSU's , they are the regural chinese type. Where should i put the ferrite choke? Between the PSU's and the drivers or between the drivers and the stepper motors?

[RCaffin]

Ferrites go on the leads from PS right where the leads come out of the PS.

Yeah, a slipping coupling - we see a lot of them.
