Reconstructing firmware settings

[kerog]

Posted this question on the new member forum, but maybe will get a quicker response if I post here.

I recently bought a used Rostock Max V2 Extended with E3D V6 hot end, but don't have the configuration.h that was used for the last Repetier firmware update (0.92.2). It looks to me like I should be able to download the latest SeeMeCNC firmware and modify it with the settings I get from the EEPROM display in Repetier Host (attached). Does this seem like a reasonable plan? If so, could someone help me out with the mapping between display values and firmware settings? They don't appear to be exact matches. Also any firmware settings associated with using the V6 would be helpful: the stock firmware seems to expect an old PEEK hot end or new HE280 with probe. I'll run M303 to get appropriate PID parameters.

Also, is there any way to adjust the tension on the EZstruder? After several days of great prints, I'm seeing occasional skipping (and associated under extrusion) that seems to indicate an inadequately tight grip on the filament.

Welcome aboard. You can mostly use the EEPROM settings for config.h, especially since the newest firmware tends to throw fits if you don't do an EEPROM clear. Firmware settings and the displayed values both come with units (usually seconds for firmware, and mm). If the units match, or aren't present, assume it works the same. For the E3D, the biggest firmware change is using the correct temp table. It should be sensor 8. After all, E3D says:

Repetier

Use thermistor definition number 8:

#define EXT0_TEMPSENSOR_TYPE 8

Or select "ATC Semitec 104-GT2" if using the Online Configuration Tool (v091)

For safety it is strongly recommended to do the following:

Set the Minimum defect temperature to ensure that the thermistor shorting out is caught by the firmware.

New in Online Configuration Tool (v092) are the two options to also improve safety:

Decouple hold variance and Decouple min temp. rise to detect the thermistor coming loose. These must be set appropriately for your system to ensure that they work properly.

Upload the new firmware to your electronics.
