In the end It is soooooo much better to just go with the HY plugin and USB RS485 Adapter. That's what I did $8.00 next day on Amazon Prime
Thanks for everyones help.
Finishing up my 4848. I am having probs with syncing/squaring up the gantry.
A is slaved to Y.
If I don't select "Home with Slave" when homing the motors spin opposite.
When Jogging they work as...
Thanks guys.
Got it working. Even though I did not find a single setting wrong.
I did a Master reset (PD0013=8). I then went back through and reentered the settings.
I am now a firm believer...
If my BoB is correctly putting out voltage (0-10v) based on RPM input (Mach3) for my Spindle speed then the problem must be on the vfd side? (HY VFD & 2.2kw Spindle)
I think I have every parameter...
Thanks Jim!
I have a CW4L2-20A-S EMI Filter.
Can I just attach L1 to one pole and L2 to the other?
Where is it best to ground the EMI? (to the VFD Ground terminal or machine frame?)
TIA

Appreciate all your help John.
Only my Z Proximity switch wiring moves via wire chain the other axis wiring are statically installed.
I am hopeful this will greatly reduce the chance of wire...
Is this why...
The Limit switch always provides 5v until it is flagged.
So If the wire breaks (because the BoB already provides a high 5v) there is nothing to bring the input to 0v so there is no...
Will do.
If I understand correctly, the Proximity switch setup I am going with will be fail safe in the same way since its active high correct?
Do I just wire my Estop to limit common ground and to the 5v high input pin?
Thanks John, you're a life saver.

I don't have your electrical wits but looking your your top diag, do you see any reason I can not just wire Brown+ to +5v Input, Blue- to Input common GND and Signal wire to one of the Input pins...
I have 5v at pin1 using the Input common ground.
I also tested the Proxy Switch from the BOB Input 5v & Common GND and it does trigger from about the exact same distance as when on 12v.
In this...
At the moment I am using my 12v lab PSU for testing the proxy switches wired only/directly. BOB is installed on the machine and has not be tested along with.
Each input pin: has 5v power, has a...

I'm using LJ12A3-4-Z/BX NPN 3 wire Proxy Switches for my new Avid CNC 4848.
The Proxy Switch signal wire (on 12v source) puts out 12v constant and when triggered drops to 0.68v,
My BOB has 4...
So all I had to do is move the 5v from the external sensor terminal to the Common Anode (DC5V) terminal and that got the low dir signal to drop to 0v and now my motors turn both directions! :)
Thanks guys for helping. I am loosing hair at this point.
Take a look at this and tell me what you think.
For some reason I am getting 5.5v hi and 3.3 low signal on the dir pins from the new...
Did you have any luck out of yours?
I got this several weeks back and finished up my electronics this week. This damn board has ran me wild. 3 computers later Win7 32bit and XP 32bit. All pc's...
Trying to get movement on my new Avid CNC machine but no dice.
I have to be missing something simple.
IDK if I need pull up resistors or if I need to do something to enable the drives.

Thanks for the help.
Sorry looking back I ment to break the acm-dcm ground bridge from the manual pic.
So if I run those straight I should be good?
Would running analog freq (P1) to AI be better than 0-10v to VI to...
Can anyone tell me if this look correct?
Thanks
Got a Macro working, here is what worked for me:
I believe if you are using Big Tex Blue Screen Set you must use the same script (M920.m1s).
M910.m1s Probably works with other screen sets.

Got it going but when it touches off It sets a large neg number (-11.5098) and runs Z up to the limit switch and I get a limit error.
I use Big Tex Blue Screen Set with the Probe built in and the...
If thats the linear rail plate you might as well send that junk back. Worthless.
I was just about to place an order too.
Wow. Scary. Keep us posted...
I was about to place an order but this is concerning.
Do you have an update on your machine?
Thanks for taking the time to do this review. Hard to find detailed info on these imports.
