You can make a program comparing the values.
Here this measures the Z-value on different X/Y positions.
Here is an example.
Actual measuring program
0 BEGIN PGM Mittaa MM
1 M31
2 TOOL...
First of all, if you can, take a backup with a TNCremo.
Then the harddisk needs to be changed.

Hi,
Does the X-axis move at all? If not, I believe the Siemens LT-modul on X-axis is broken.
You can test this by exchanging the LT-unit with Y-axis and test it again.
Put the machine in...
The problem is on the drive offsets. Enter the code 75368 and accept the values. This is memory based offset correction. Alternatively you can adjust the offset from the drives. Put the display to...
The A/B has the PLC inside the control. The versions P/Q has the external PLC.
Manuals you can find here: https://www.heidenhain.de/de_EN/software/
The problem is on the encoder inside the motor.
That is either broken or contaminated. Needs to be adjusted correctly.
Do you still have this problem?
Hi "Old Dog"
Is your problem solved?
If not maybe I can help you on this.
To solve the problem I need the NC software version of you TNC 426.
A backup from the control with TNCremoNT would be...
B version is the later model.
But they are different. In the B version PLC I/O is built in. The P version needs the external PLC I/O card.
Hi,
My question is why? TNC430 is far better than TNC128.

Hi,
Yes, it is possible. Tell me what is your problem?

Hi,
What kind of kinematics (tilting axes) you have on your machine?
In the OEM.SYS you need the KINEMATIC = PLC:\KINEMATIC\KINELIST.TAB line.
Then in this file you need all the kinematic...
To have the "3D ROT" softkey active you need to have the kinematic files correctly adjusted.
In the OEM.SYS you define the main kinematic list with KINEMATIC = PLC:\KINEMATIC\KINELIST.TAB (example)...
Well, that depends where you are.
Forst of all you need to buy the iTNC530 analog version with the UV-power supply, the keyboard and the screen.
Then there is some work to be done. Shift the...
Hi!
You can do it with the TNCremoNT
Hi Wudan,
Yes, I do still have that display in stock.
Do you want to have it ?
Jukka
Hi there!
1. You handle the G17, G18 and G19 in plain language with TOOL CALL block with axis information!
2. I think there is something wrong with your program. Send a copy of it and I'll be...
Hi!

Hello,
This has to be a problem of kinematics. Maybe your machine is configured to work so that the "Angles correspond to the position of the tilting
axes of the head/table".
In that case you...
Hi!
Error message [y measuring system defective] coimes from the Y-axis measuring system. On your case I think the encoder on the motor. Except if you have scales installed.
You could change the...
Ok.
Let me know if you need any help on your project.
Well...
The hardware is less than that.
And if you do the work (I could help you with "how to do it") it is going to be much less than 20k€

Hi!
Again one 370!
Yes you can connect the ERO encoder to 370. This encoder signal is 16uApp.
Then you need to adjust the parameters for you table.
Then you need to check the PLC of your 370.
...
Hi all!
Forget the TNC370! Retrofit the machine with iTNC530.
Very easy job on Bridgeport machines with TNC370! Can be done in two or three days!
And the advantages with iTNC530 shuold be clear...
Hello Michael.
That is the kv factor for axes. Try to set up first 1 to all of them.
But that is not all. You need to adjust the speedloop of the machine.
Have you got the machine running...
Hello Littlepad
I just happen to have two TNC370 screens in stock (used ones)
Do you want one? We could find a reasonable price for it.
But I have a much better idea!
Why don't we retrofit your...
Hi,
Well, all the information except the date and the clock is on the harddisk.
So you won't loose parameters nor programs.
Anyway, I too advice you to change the battery. It is Renata CR2450N....
Hi,
Here is an example:
0 BEGIN PGM test MM
1 FN 18: SYSREAD Q1 = ID270 NR1 IDX1 ; Read X-axis position
2 FN 18: SYSREAD Q2 = ID270 NR1 IDX2 ; Read Y-axis position
3 FN 17: SYSWRITE ID...
HI,
Check the lag display while running the axes. The values shuold be same at both axes (X and Y) while running at the same speed. Usually I run my tests at F1000mm/min.
Depending on your...
