Plotter Scale Calibration changes nothing after saving new settings.

[Anonymous]

HP DesignJet T125

AutoCAD 2021 LT

Length (x axis) scale is short by 1/32"± every 12"

ran the "calibrate your plotter" wizard

print the first sheet

filled in the actual measurements

printed the new test page which is measured to be 100% spot on

save the settings to a pmp file

attached that pmp to the plotter's pc3 file

print a test scale that i drew in a normal drawing with the exact pc3 that I just attached the pmp to

the problem persists. 1/32"± every 12"

Setting this up as a template printer for cutting plates so the scale needs to be spot on.

Hi @Anonymous,

I see that you are visiting as a new member to the AutoCAD forum. Welcome to the Autodesk Community!

I understand that after running the plotter calibration, the test page plots correctly, but it does not plot correctly when plotting your test scale drawing. I can imagine how frustrating that would be. 

I see you note that the measurement is off by 1/32 plus or minus. Does it vary over and under on different plots?

Are you able to test plotting with that PMP file to another printer or to PDF and check the measurements? 

I would be happy to run some tests if you would like to share your test scale file and PMP.

Hello 

cheryl.buck

Attached are the relevant files

The measurements do not vary with each print. They're spot on with how much off they come out. 

Thank you!

Hi @Anonymous,

Thank you for sharing the files PMP and PDF files. Can you send the DWG file you are plotting from when you see the error? I will need it to troubleshoot the issue. 

Were you able to test plotting to a different driver or printer? 

All the best,

Hi @Anonymous,

I am checking back to see if you still need help with this issue. If you were able to resolve it, please post an update letting the community know your solution.

>>>...the problem persists. 1/32"± every 12"...<<<
What industry are you it that a paper print shortage so small is a deal breaker?
Or, what is it you are trying to do exactly? Paper stretches when heated/cooled, I suspect you are seeing that margin or error, nothing more.

The HP T125 is accoding to HP "Ideal for: Architects, engineering, and construction professionals working in home or small offices who need a compact, easy to use, affordable plotter in-house."

If you are cutting plates (not paper), your paper printer is the wrong tool to get there I suspect.

Hi,

I have the same problem. Used to use very old 2009 version of AutoCad. Calibration was ok, installed new 2021 and seems like it doesn't save the changes. When doing the Cailbration first it was -0.5mm off. Made the changes and checked calibartion, everything was ok, but when i finish the calibration it seems that it doesn't save the correction. When plotting the drawing is few -mm off.

The problem exists on normal weight and heavy weight stock, no difference.
I'm not 'cutting' anything.
I print templates on heavy weight stock. These templates have holes and shapes on them. Center to center accuracy is critical.
We are metal fabricators, our assemblies will not "bolt -up" if they are out of tolerance.
Small angles and plates (less than 12") can usually accept the variation.

@Anonymous @Anonymous Feel free to report any problems you see with AutoCAD/LT2021 to Autodesk here too https://www.autodesk.com/company/contact-us/product-feedback

You both also need to do what the Staffer asked for here too (PC3 or driver version, PMP, PDF and DWG files) https://forums.autodesk.com/t5/autocad-lt-forum/plotter-scale-calibration-changes-nothing-after-savi...

Sorry but can't send anything because it's all confidental. The problem is with all the files.

Hi, I'm experiencing the same issues and was curious what your solution was to fixing the scale calibration? I also ran the scale calibration and the test print makes the correct adjustments but when I open a new file it prints out of scale. This is so frustrating! Currently running AutoCAD 2021. Thanks, Dustin

It just somehow fixed itself. Installed update and poof it was gone.

What AutoCAD version are you using? @Anonymous  I'm running 2021. Thanks
