Welcome to the SeeMeCNC Community

Hi, as stated in the description, I get a delta overflow when the EEPROM_MODE is set to 1. This happens whenever I try and Home the printer from Repetier. Specifically, it happens whenever moving upwards.

I thought maybe there is something funky in the EEPROM that is screwing with my settings, so I was going to try and erase the EEPROM and do a clean upload of the repetiermax firmware. The most relevant information I found on resetting the EEPROM was from: http://arduino.cc/en/Tutorial/EEPROMClear. I'm just wondering if there is any harm that you guys forsee in doing this before I follow through.

Well, first question in my mind would be whether the printer gives the same error when running with EEPROM mode disabled (set to 0 in configuration.h)? You can also basically force Repetier to reload all of the EEPROM settings by setting the value of the EEPROM mode to something greater than zero and different than the previous value, so if your EEPROM mode was set to 1, for example, setting it to 2 will force the configuration.h values to be written into EEPROM, overwriting what's there. At least that's how I read the firmware comments.

The printer doesn't cause issues when EEPROM_MODE = 0. But changing the value to 2 worked. Now I've changed it back to 1 and everything seems good. What I found odd is that the comments also state that:

" If you later want to overwrite your current
eeprom settings with configuration defaults, just change EEPROM_MODE to 0 and upload, then power cycle your board."

Which to me meant,
1. EEPROM_MODE 0 and Upload
2. reset RAMBO
3. EEPROM_MODE 1 and Upload

and then the EEPROM should be set to defaults, but that didn't seem to work.

Ah well... its working now. Thanks!
