#1--going to Diagnostic area to check all alarms, I think there should be more than one alarms

#2--take picture of 840D NCU front with power up ending

it seems your system lost data

 From your pictures I see the NCU is normal , but it seems that your system lost data ,

please going to Services area -->find in Archive \ abcs.arc the back up data 

you need to reload good back up data and to see what's going on?

If you not familiar for load data, just go to "Services"--data manager--> Archive--> then send screenshot to here, I give you help  

bill_djillali840d

 message "job has terminated with error " means the back up data is no good.

I asked you show the picture of "Services-->Data Manager--> Archive--> want to see are there any NC,PLC archive, you may try to load from there

bill_djillali840d

Hi, i actually did ask the machine company (durma laser) for nc /plc backups

and they send me the files,

idid the nc backup from the disk flash and entered the password, and while it was loading

The communication failure error was appearing multiple time and it fineshed the loading with that messages ( job has terminated with error) as i mentioned before 

Note : I didn't try to load the plc backup)

Thank you for your help again. 

 It looks better, I don't think you need reconfigure axis. you have alarm X axis drive defective

please take picture of the drive --need very close looking of all drives -I will help you

 it seems now you only have one alarm--which is most easy to fix. going to STARTUP-->Machine Data-->Axis MD--> page to X axis (right top Conner-X)--> find MD 36110 , for SW limit plus and MD36100 for minus  --you need change those value to meet you working condition normally 2 to 5 mm before to mechanical end

BTW--you said "Thank you so much for your help" --I hope you can do more for me, not only Thanks in your text --read my signature --left bottom to Thank and right top to rate

When i launched measurements test the x and x2 was showing same position value

When i tried jogging the x axis the drive goes off and the x, x2 values are slightly different 

Good!  you find correct MD's just write down the original numbers and go ahead to change the number,

I see you have alarm for X - (minus) so you need modify sw limit minus  

then reset (reset button on MCP--machine control panel) 

You may need change both X1 and X2 until reset SW limit alarm

share the result please

Hi sir hope you're having a good time

I have some pics here for the 

36100/36110 x1 x2 axis

Notice that the machine specs for x travel 

Is (3060mm) 

 you are  quit NEW for CNC, you can call it old number or old value --Let me check you picture

see your pic, -3mm and 3070 are old value.

for me, I always take picture or write it down before change anything

bill_djillali840d

Sorry! What original numbers i should write

I didn't understand 😅

Now I don't understand you!  is it your 1st CNC machine?  if yes you need call someone in your local with experience. or you want my deeper help , PM me 

bill_djillali840d

How i change the numbers

Based on what?

Cuz i think that the limit values are correct with the machine settings 

But the reference positions for x /x1 are wrong!

I can share a picture of the head position in buttom right position. 

So the x should be zeroed there?!
