Validating separate XY 5160pros and 2209s as before for everything else
Before I blow something else up...I want to makes sure I'm setting these jumpers correctly and doing this in the proper order.
I just rewired all my AC mains stuff having added a 48VDC supply (cleaned up while I was there.) Octopus Pro 446
ref'ing the drawing at https://os.ratrig.com/docs/boards/btt/octopus-pro-446
I want to validate my 'adjustments' to jumpers are correct.
(see attached pic.)
1- GREEN ARROWS - move motor power jumpers to the left to run on separate motor input terminal power T/F?
2- BLACK arrows - input from 48VDC supply
3- RED ARROWS - add jumpers to ALL four terminals to put the 5160s in SPI mode. T/F? ?? ...now the biggie.... 4- Re-install new 5160 Pros in the XY sockets. 5- without the 48VDC power turned OFF ... turn on the printer so I can edit the printer config 'literally' as per https://os.ratrig.com/docs/configuration/advanced-stepper-configuration as documented (this is still correct for RO 1.x??) - raises the question...will power up of the 5160's seeing signal with no power supply be an issue? 6- save printer.cfg. 7- shutdown...hook up 48VDC supply 8- powerup and pray. tia - just want to make sure i'm not out in left field as usual.

Advanced Stepper Configuration | RatOS
RatOS V1.1 introduced modularized stepper and driver configuration, this can be used for more fine grained control of your steppers. In your printer.cfg you might have noticed a section like this:

1) ✅

3) ✅
4) ✅
5) No reason to have it turned off, you'll get an error regardless until you've removed the tmc2209 sections for X/Y and added tmc5160 sections for x/y. Nothing will blow up 🙂
6) ✅
7) Should already be hooked up
8) No reason to power down after editing the config, it'll work after you fixed printer.cfg
tnx!
impatient here... decided to test my instincts. haha .... no smoke.
One item I noticed.... TMC2209 vs the TMC5160 Pro.... I had to invert the direction signal (dir_pin)...
So regardless of what I had originally (which was !dir_pin for the way I was wired up) I had to invert it for the 5160 Pros

Yes this is just the nature of the pinout on 2209 / 5160.
