After updating Redeem through apt-get my Z axis no longer moves.

After updating Redeem through apt-get my Z axis no longer moves. I have most variables defined in my local.cfg file for my printer so nothing should have been overwritten.

What should I be looking at to troubleshoot this? I’m not getting anything terribly useful out of the debug logs. I can hear my steppers power up when the drivers power on from idle.

Does not seem to be an endstop issue, either:

Send: M119
Recv: ok X1: True, X2: False, Y1: True, Y2: False, Z1: False, Z2: False

Have you checked your soft endstop limits?

@Daryl_Bond Yep, they’re the same as before. :frowning:

end_stop_Z1_stops = z_neg,h_neg

soft_end_stop_min_z = -0.5
soft_end_stop_min_h = -0.5

soft_end_stop_max_z = 0.3
soft_end_stop_max_h = 0.3

Well I’ve figured it out. I might be crazy but it looks like the syntax changed for setting slave steppers.

Old = slave_h = Z (from previous local.cfg which was working before updating redeem)
New = slave_z = H (updated after re-checking the wiki)

Good to know you found it! There should have been a readout at the start of the log about the axis slaving, is that what pointed you in the right direction?

@Daryl_Bond I wasn’t seeing anything in the log files about stepper slaving that jumped out at me. However, for investigative sake I flipped the syntax back to the original to see if anything changed in the logs. Since both configs are valid from a config standpoint there were no errors.

Tiny crumbs of info! :slight_smile:

slave_h = Z

Yeah, the info is there but it is pretty hard to spot! Do you want to raise a ticket on the repo asking for clearer logging of the slave settings?
