Internal error during connect: 'ManualExtruderStepper' object has no attribute 'cmd_SET_E_STEP_DISTANCE'

[koekie40]

I am going through set up of Happy Hare V3 now and I'm getting this error 'ManualExtruderStepper' object has no attribute 'cmd_SET_E_STEP_DISTANCE'
I am still kind of new Happy Hare and the ERCF ERCF v1.1. i have also try to do a restart a Firmware restart
I am following the guide and I'm afraid I'm over looking something simple.

how up to date is klipper? Theres been allot of changes to klipper over the last 12-mths that required updates to HH and there is now a dependency between to two so will need to keep klipper reasonably up to date.

Update klipper and try again

Hi, sorry for the delay. You are using and VERY old version of Happy Hare that is deprecated and not supported anymore. The new version v2.7.3 and soon to be released v3.0.1 don't use ManualSteppers.

It is possible that if you did upgrade to v2.7.3 / v3.0.0 from a very old version that the upgrade of mmu_hardware.cfg was not able to be performed. The best thing to do is to save the info from that file (then DELETE the file) and re-run:

./install.sh -i

This will re-create a correct mmu_hardware.cfg to which you can apply the configuration from your previous install.
