ABS V2Calibration
It's getting a bit annoying having to swap out the loaded ABS filament for a bit of PLA each time I need to run the V2Calibration after running the XYZ calibration (which on 3.0.8 is essentially every time), as I'm on a pretty consistent -1.200 mm Z offset.
Can I just replace the temperatures set in the M104, M140, M190 and M109 lines with the appropriate ones for ABS, or is there more to a V2Calibration dedicated for ABS instead of PLA?
current (PLA):
M107
M104 S210
M140 S55
M190 S55
M109 S210
G87
...
Desired after (ABS):
M107
M104 S255
M140 S100
M190 S100
M109 S255
G87
...
edit: got the temperatures wrong in the after.
Re: ABS V2Calibration
Errr Why run XYZ calibration every time? Why run V2Caligration more than once?
Since I installed 3.0.8, I have only run those procedures once, when installed. The printer just keeps on running with no further calibration required.

Re: ABS V2Calibration
I tend to do an XYZ calibration after each time I had to move the printer.
When having done so, the printer will keep prompting the "printer has not been calibrated yet" message on booting (and the Z adjustment isn't remembered) until I run a V2 calibration.
If I understand vojtěch.b3 correctly, this is actually by design and the G87 command resets/disables the message: http://shop.prusa3d.com/forum/original-prusa-i3-mk2-f23/new-3-0-8-firmware-released--t1642-s20.html#p12786
I now gather from SBS' post that it is indeed a matter of simply altering the temperatures, as he did so for PETG: http://shop.prusa3d.com/forum/original-prusa-i3-mk2-f23/new-3-0-8-firmware-released--t1642-s20.html#p12874
Re: ABS V2Calibration
Firstly, stop moving the printer 😉
Yes, you can simply amend the GCode temperatures, but you could also include M87 in the start GCode section of your slicer...
Then every print will reset the "calibrated" flag and you can use Z live adjust as necessary on the first layer of any print.

Re: ABS V2Calibration
I will jump in here and be one to also "want" an ABS calibration template for the MK2. I only print with ABS and now have no PLA 😕 so it would be really nice if there was an official ABS calibration available....... Pretty please Prusa 😀
Re: ABS V2Calibration
Laziness rules the world. 🙄
Just get a copy of V2Calibration.gcode, open it in favourite text editor and change the temperatures by hand, save and done. Comeon, it's not so difficult. 😎

No need for that. Ever thought that some people just don't know? They are willing to learn but such comments just stops them asking.
It costs nothing to ignore the post or post a helpful response.

It is a simple process to change the V2Calibration gcode file for ABS use as follows:
Get the GCOde file onto your PC.
Download a decent text editor (such as Notepad ++ (best not to use Windows Notepad).
Open the GCode file with the text editor - you will see the starting lines:
M107
M104 S210
M140 S55
M190 S55
M109 S210
G87
or similar.
Amend the temperatures (210 and 55 - 2 lines each) to the temperatures you require (maybe 240 and 100)
Save the file and close the text editor (Note that is using Notepad++, simply closing the program will not save the file)
Print the amended V2Calibration file from your PC or rename it (eg V2CalABS.gcode) and copy it to the SD card.

Re: ABS V2Calibration
No comment David. Please read, I stated "Official" 🙄
An official version will stop any problems. Not all users know how to change Gcode. Would just be a nice idea to have options. The PLA and ABS calibration versions would cover pretty much most of the filament types out there.

Of course. And I know the same information was said thousand times before me.
Sorry for being impatient.
Edit: I still think making another gcode for ABS calibration is wrong way. After that there will be another people asking why there is no gcode for FLEX/PET/PC/NYLON/put your favourite material here. The solution is not to make special gcode for every material in the world. The solution is to teach people how to customize the default one (provided by PR).
Or to make universal one without temperature control and let people preheat printer to desired temperatures, but this is less safe as someone could run it on cold printer.
