Bench testing new OAK with CNC12

[jason1098]

DannyB - 8 installs in the last few weeks.... good job. Setting parameter 35 to 0 has got me to the MDI prompt to test the DC voltage (0-10 VDC) from the board. This seems to be the only test of the OAK board and the reason for going through all of this frustration. Now that I can get the MDI up, i'm able to hook up the multimeter to the spindle output and common to read the voltage ranging through spindle speeds set using MDI commands. this is now where i'm stuck. I read 0 VDC when the spindle is at 0, but when i change the speed, I get a new fault: 327 Fault - Job Cancelled.

If changed the following parameters to get the MDI up and able to input:
Parameter 35 from 6 to 0
parameter 348 from 15 to 0
parameter 170 from 1 to 5 (a suggestion to get the feed rate override from being stuck at 1%)

the voltage on spindle out measures 0 vdc at rest and then i can not get the MDI command to take anything without faulting. Using the VCP to control the spindle (the virtual spindle, since it's not hooked up physically yet because this is only a bench test of the board) allows me to move the spindle progress bar, but the voltage does not change.

The one thing that I didn't follow in the instructions was hooking up the 24v to the board. The molex connector is hooked up as wired, but the instructions say to hook up position 1 and 2 from H1 on the Oak board to V4 and COM respectively on the power supply. The picture shows the hook up from the board going to position V3 (not V4 like the manual says) and COM. Since V3 on the power supply is labeled and measures 24V and the H1 input on the board position 1 is labelled "+24 V" i figured that the picture and the labeling were correct - and the manual was wrong.

what other things might be in my way to test the 0-10VDC output of the spindle?

Thanks!

I just finished testing an Oak. Customer picked it up yesterday. Wished I still had it, I could have done a video on it. I've not had the problems you are having.
Please post an updated report.

Marty -

All of this is to bench test the board and test the voltage output of the board to be sure that it measures 0-10VDC. That seems to be the only test that is listed. I watched your bench test video again on the Allin1DC thinking that i might get some additional information from that. It seems like even though it is similar to the OAK, it still is different.

I don't want to skip the bench testing of the board, so I will try to struggle through it. Is there a place in the software to be sure that the spindle output is set to output 0-10 V DC? right now, i'm only reading 0. I've manually changed the virtual spindle speed using the VCP, but my reading is still at 0 VDC regardless of the what the spindle speed is.

I still get an error every time i type "M3 S 750" from the MDI.

Did you bench test the OAK as detailed in the installation manual?

Thanks,

[DannyB]

So, I usually bench test the board first, then bench test it with servos/etc connected to make sure everything works, then shove it all in the enclosure.

As for the specific issue you are having.

My recollection on spindle speed is that it will not output anything other than 0 until you issue an m3/m4 (for safety reasons)

So you won't get anything other than zero until you can get it to m3 properly.

So need to figure out and fix the MDI issue.

Post a report after one of those faults so folks can take a look and try to see what's up.

Please also post a screen shot of your ALT-i diagnostic screen

we are working on updating the Oak and Allin1Dc install manuals. in meantime please follow forum protocol found here..viewtopic.php?f=20&t=383
and we will be glad to help you out.
most important is a FRESH report.zip with each post you make.

Bench testing status:

I am attaching a fresh report.zip along with the error log file (msg_log.txt)

I am now able to enter MDI commands, but unable to get past the faults. I am attempting to measure the voltage from the 0-10V dc output on the board per the bench testing instructions. Every time I enter m3 S 750, I get: 327 Fault: job cancelled. I have tried different formating of the m3 command, in case it is sensitive to the character spacing.

per Marty's request, here is a screenshot of my real time i/o:

I am also attaching a few other screenshots in case something jumps out to someone:

Any help would be greatly appreciated.

Here is my most recent report file.

On the Control Configuration screen, you should probably have "PLC Type" set to "Standard", rather than "None".

Up front, I should admit I have not read the installation manual, and do not have time to do so right now. I have, however, installed quite a few Oak-based control systems.

That said, I think you are wasting your time trying to complete this "bench test" procedure with no servo drives connected. I would not necessarily expect CNC12 to function predictably with all axes labeled 'N', since that is an unusual condition that the software was not designed around.

You have established that the Oak unit boots up and talks to the CNC12 software on your PC. That is good enough at this stage. Turn your attention to something useful, like getting your emergency stop pushbutton wired to INP11, and getting your servo amplifiers connected.

[jason1098]

I completely agree... much better use of my time to hook up the servos and move ahead.... the manual is very specific and says in bold to complete this step, so I figured I'd follow instructions for once. (my wife wishes I followed instructions more often)

I will try to reinstall the PLC program. I thought that I had picked "Standard" during the installation of CNC 12, but perhaps it didn't take as I expected.

Thanks for your honest advice.
