z-axis feed ajustment

[JustSumGuy]

I have an older ME Creator (not the version 2)

I want to replace the M8 threaded rod with an actual 8mm feed screw.

To do this I will have to adjust something for the pitch from what I believe is 1mm per rotation to the new 2mm per rotation.

Where would this be changed? I was assuming it would be in the software when I ordered the feed screw.

As I search around I am finding I may have to learn how to do the adjustment in the printer firmware itself?

I am not a programmer...

thanx in advance

additional information:

board is a Sanguinololu 1.3a I have found a firmware but am still lost.

Installed Arduino IDE 1.84 and tried to set it up but have no idea what board to set it for.

Found a wiki that said the Sanguinololu needs to use an older IDE so I downloaded the old 0022 release. Still no Sanguinololu in the board selection.

Ya I am lost.....


help please

Glad to hear that,could you sharing your solving experience about your case?It may help someone who have the same issue better.

Essentially I found that the Sanguinololu 1.3a board that was supplied with my ME Creator has a bootloader that does not support USB F/W updates.

To resolve this shortcoming I created an arduino ISP programmer and connected to the ISP header on the Sanguinololu directly.

I still had to use an older Arduino IDE as the newest one Ver 1.84 is not compatible with the old Sanguino chip.

Using 1.6 resolved this.

I now have Marlin 1.1.1 installed and configured for the changes I have made.
