bot wah are the eprom changes I need to do?

Hey duvdev,

I'm not using a RAMBO anymore, so you'll want to fact-check this response. You'll need to update your Ext1 Steps per mm, and maybe reduce the drive current for Ext1 as well.

Firstly, if you've ordered the kysan 5.18:1 geared stepper, make sure you order the 8mm bore hobbed gear at the same time, the ezstruder hobbed gear will not fit.

You can change the steps per mm for your extruder in eeprom. I have mine set to 439.69.
You will want to go through the entire extruder calibration procedure from geneb's manual.

The kysan stepper spec says that it runs at a lower max current than the stock extruder stepper.
Kysan = 1.0 amps, Stock Wantai = 1.5 amps.

If you're finding that the geared stepper is running very hot, you may have to recompile your firmware to use a lower stepper current.
The relevant section in Configuration.h, extruder1 is the fourth value in the MOTOR_CURRENT {195,195,195,200,0} line...

i only saw the setup for the chimera.
and i need the setup for the cyclops
