Should be 2 on X, 2 on Y and 2 on Z. Step and direction only!

Yeah, he has four axis so a total of 8
He also put them on his enables........

I only see three axis on the screen picture but oh well....Added later maybe?

You are right Dave!
He stuck resistors on an unused axis.
Needs to fix that, 6 resistors all that is needed....

The new schematic shows the 100 ohm resistor on the enable as well for +5VDC.

You are correct: viewtopic.php?f=60&t=5531
I think I will continue to use C86ACCP from CNC4PC.com as it handles everything and Teknic reviewed it.

Thanks for dissecting the pictures.
The latest schematic showed 3 resistors per axis and in my "many permutations " I removed the enable resistors and the unused axis which I had placed for future use and still had no movement .
I too am considering a move to the C86ACCP board but the system is once again working in the interim and I have to complete the counterbalance mechanism for the Z axis.
Sorry to be one of "those guys " who didn't send the report but still distracted by
Other issues. Thought I would try to at least partially reply to your suggestions.
I'll have to get additional crimping tools to do the Molex connectors before the move to the C86ACCP.
IN THE INTERIM I THOUGHT IT WAS A NECESSARY EXPEDIENT TO GET THE WORD OUT ABOUT THE VRS SOFTWARE SOLUTION IN THE TEKNIC MSP2.0 program that had been causing me " ERRACTIC BEHAVIOR" DRIVE FAULTS and the plunging crashes accompanied by the resetting of the home position of the Z axis.
To be continued......

The next version of C86ACCP will also have terminal blocks for cut signal cables. So no need for crimping unless you want to. It is due out in the next 2-3 weeks.
I will be testing it.

I had the exact same experience, I tried adding the resistors per the schematic but it resulted in zero movement! I've already cut the cable ends off, thinking I should have just bought the C86ACCP board... :cry:

Edit: Runs great in the original configuration (no resistors) for extended periods of time before I get the timing fault (typically on the Z axis)

Edit: problem resolved by adding 10k pull up resistors tied to 24v to the step, direction and enable terminals of each axis

Hi, I just did a conversion using Clearpath NEMA 34 servos and Acorn on a journeyman 425. It works great! I am still playing with motor profiles to optimize rapids but it does a nice job. My son and I made adaptor plates to fit the servos into the existing drive mounts. I gutted the entire machine and got rid of the giant electrical panels which really streamlined the machine. Is there a particular question you have regarding the install?

I also just completed a ALLIN1DC upgrade from the old DC3IO on a 5x5 router table. Love it!

Any thoughts on why the z axis motor would randomly disable and drop like a rock. But f I push on the Factory cable it will turn back to green and work. The fault is isolated the the z axis motor and I sent the motor back to the factor to be checked it was returned without comment. Fault usually occurs prior to homing. It would appear to be a bad cable or a bad motor connection. Any thought would be appreciated. Its not safe to leave it like this
