Problem with calibration

[jonyzdude]

I calibrated the xyz towers perfectly and then when i ran script 4 the hot end pinned the paper. So i read the instructions and this would be considered a concavity. I went in to arduino and changed the eeprom mode to 0 like they said to do and then bumped the printer radius down. When i saved it and uploaded it two things go on. 1- when i run script 4 the hot end is exactly 1"15/16 from the hot plate. 2- The speed is 100%. Now when i run a script 1,2 or 3 i have to kill it half way down because it wants to bury itself into the side of the supports thus going beyond its perimeters. When i change the printer radius up or down it doesn't matter, the script 4 always stops 1"15/16 from the hot plate. Any help would be appreciated.

Thanks

On the LCD, Calibrate Z height, rotate the knob till it's close to the table (about the thickness of a sheet of paper), press the knob and select "set new Z"

Are you changing the Eeprom setting in mattercontrol?

I have changed the Printer radius different times and it always seems to end up about 1"15/16 above the build platform.

Is this a Rostock Max v2 we're talking about?

Not sure where you found an instruction saying to do that. As I understand it, setting eeprom mode to 0 causes the firmware to override the values in eeprom. So, if you set your Z height in eeprom and then set mode to 0, firmware will use default values from config which is why the head is high above the platform now.

This is the Rostock Max. I bought it in 2013.

You can do this by locating the line in Configuration.h that reads “#define EEPROM_MODE” You'll change the value
that's listed to “0” in order to turn off the EEPROM feature. Once your PRINTER_RADIUS
configuration is completed, change it back to “1” to re-enable the EEPROM.

I took this out of the instructional guide.

I think you are looking at an old manual. The up to date manual does not have you disable the eeprom. Although you may have a Max V1, use the Max V2 manual (Rostock-MAX-v2-Assembly-Guide-2ndEdition). Defeating the eeprom is why the head is at the wrong height.
