skip calibrate encoder when using tradrack #317

Open LE1ED4523 opened 3 months ago

LE1ED4523 commented 3 months ago

I have set my mmu_vendor in mmu_parameters.cfg to tradrack PixPin_2024-06-18_12-59-05 I calibrated other parameters but when I want to load it tell me prerequsite calibration steps are not complete. Please run: MMU_CALIBRATE_ENCODER PixPin_2024-06-18_13-03-38 wiki only say Calibrate your encoder (if fitted) how can I calibrate it or skip the calibration if I don't have any encoder

Can you give me more context on where you are in your journey...

Did you call "MMU_PRELOAD"? That requires full calibration but the encoder calibration should be optional so maybe setup is incomplete elsewhere and I suspect it is this:

Without encoder. Edit mmu_parameters.cfg:

gate_homing_endstop: mmu_gate

This is because you have a gate sensor on the Tradrack so need to use that and not the encoder measurements for parking.

This isn't automatic because many Tradrack users have encoder, but I can probably improve the install over time..
