We would to ask for help on resetting count down timer after making an oil change for Turbo Blower and Vacuum on laser cutting machine Amada LC-2415A3 with Fanuc 160i-L controller.
This machine is serviced by Amada, Fanuc, in-house technician, and private service company... no one knew exactly how this could happen.
Our current focus is on a different issue. Due to the rather inexperienced technicians from Amada... during their 2-month troubleshooting sessions, our...
At last, we found the problem... a very simple one.
The JA6 cable was plugged into the wrong socket (on the wrong board).
See the attached picture... someone mistakenly made red-color marks on the JD6A socket and the JA6 plug... so even though we checked the JA6 plug so many times, it was...
Attached is the detailed voltage output of the HS-2000 board.

@ausman
Thank you very much for your info... please advise:
1. Did you get those readings with JA6 cable plugged in to Fanuc board (or without)?
2. I believed you meant to type "-8.9V with 0.8mm", is that correct?
We will try the G32 R_ command tomorrow and reply.
By the way, we don't know how to test for shorting to the cone... so we removed the cone from the head and placed it outside the machine on the concrete floor. Then we connected the Z-sensor and Ground cables to it.
No Z-sensor wire break alarm... but the "Trace Data" remained stuck at 20-28...
@sparky4808
HS sensor calibration ran faultless both with "Trace Off" and without "Trace Off" (during which time the "Trace Data" remained stuck at 20-28).
We measured the output voltage across the "Sensor Out" pins of the HS-2000 board (the pins where the JA6 cable was plugged into) while...
I need help in verifying whether this is normal.
1. I pulled the Trace Data onto the screen.
2. Trace data reading was 20-28 (fluctuating).
3. External Z-Sensor was pulled out... wire break alarm.
4. Put back Z-Sensor... alarm went away.
5. Removed nozzle... wire break alarm.
6. Put your finger...
Still... the problem remains.
HS-98 Regulation sequence...OK
Z-Sensor Wire Break alarm... OK
Trace data... not OK (stuck at 28)
Cutting (with Trace Off)... OK
Cutting (no Trace Off)... not OK (failed to "look for" material and tracing not working)
Aaaaahhh... this is getting discouraging.
@LaserSpyder
We pressed the operation stop button by mistake, sorry.
Update...
Yesterday Fanuc technician came in to check the serial comm. board that the JA6 cable was plugged into... not faulty.
To summarize what we had done to date:
Cone... checked
Ceramic Ring... checked
External Z...
Amada technicians recently came with spareparts... replacing the cone + nozzle + external cable + internal cable + HS-2000 board.
Still did not solve the problem.
What they did not replace were the JA6 and the ribbon cables. But they did check both cables for connection faults (did not find...
Yes... I read that thread many many times... very informative.
jjl1210:
When material thickness was set at 1.2 mm, the head started cutting at 11-12 mm above the material (the Z value on the screen was fluctuating all the time but within this range)... when I changed the thickness to 0.5 mm...
Thank you for all the advice... will try them out in the evening and report the results.
The local technician mentioned that he used to adjust touch level of HS-2003 (FO machine) by changing K48.1 value from 0 to 1... and then adjust manually (but he doubted that the HS-2000 will use the same...
We just had the short z-sensor cable replaced, and the machine worked fine for 1 day. The next day, the head did not detect the sheet metal but stopped at 14-15 mm above the sheet and start cutting.
We are using HS-2000 sensor. Head calibration worked fine (with Trace OFF). See Video here...
