Looking at Pegasus 12

[printbus]

what file is that in?

configuration.h

What does Colin say about all this? That's not the "right" driver for the printer. That is the one that ships with the Deluxe upgrade kit.

We did get the upgrade at the same time, but haven't done any of the upgrades as most require printing something.

Well then that's the explanation (and the missing information). You need to either use the correct stepper driver or mount the acme screw Z axis stuff to get it working with standard firmware.

But first we have to print the mounts for the ACME rods with funky settings, a Catch-22. We're just going to have the rod mounts printed for us this week and swap to the ACME rods this weekend and be done with it.

The other big issue is the Marlin won't recognize 4 different SD cards.

[uncle_bob]

How did you format the SD cards and how big are they?

[mook898]

1gb to 16gb all formatted in fat32

[uncle_bob]

Freshly formatted on what OS?

My guess is that the format isn't the issue and you have a broken / unseated cable. The whole format issue is what you need to dig through first though. There *are* well known issues in that regard.

I formatted SD cards with windows 10. I tried switching cables around today and making sure they were seated correctly. Still same as far as info screen says sd card inserted and next screen says no sd card. Augerpro suggested we try and reformat cards one more time. Would you recommend a different OS to format?

[uncle_bob]

Hi

I would format it on a Windows 7 machine if you suspect that Win 10 might be an issue. I format them on OS-X and Linux. In any case you want to be sure that it is a FAT file system.
