Problem with manual stepper (case-sensitivity, no response?) #2146

Closed ghost closed 5 years ago

ghost commented 5 years ago

My config: SKR Pro Board from Bigtreetech with TMC5160 V1.2 from Bigtreetech. Raspberry Pi 4 B running Duet Web Control

I want to use a manual stepper for cutting filament, so I defined it as:

[manual_stepper cutter] step_pin = PD15 dir_pin = PE7 enable_pin = !PA3 step_distance = .003125 velocity = 70 accel = 1200

When I issue "MANUAL_STEPPER STEPPER=CUTTER ENABLE=1 MOVE=10" the response is "failed: MANUAL_STEPPERThe value 'CUTTER' is not valid for STEPPER"

It makes no difference if I issue CUTTER or cutter on the gcode console, the output is the same and always uppercase.

Then I changed cutter to CUTTER in the printer.cfg, so it is now:

[manual_stepper CUTTER] step_pin = PD15 dir_pin = PE7 enable_pin = !PA3 step_distance = .003125 velocity = 70 accel = 1200

When I run "MANUAL_STEPPER STEPPER=CUTTER ENABLE=1 MOVE=10" the g-code console get's stuck, as it is waiting for a return message that never comes. Also there is no movement from the stepper.

All steps can be seen in the klippy.log, I did a fresh restart before the experiment to get a clean log that shows only the behaviour described above.

This repo is only for issues with the pristine code from this repo. In order for us to assist, you will need to reproduce with the pristine code and provide a log from that.

I'm not really sure what you mean by that? I installed Klipper as instructed, I didn't change anything in the Klipper code. I made only changes to printer.cfg, nothing else.

The dwc code alters the internal state of Klipper - it is not supported here.

Octoprint does not?

@Spacemarine2018 octoprint doesn't, you can test with it safely

Indeed, once I switched to Octoprint, the issue was gone. It seems DWC somehow tinkers with upper-/lowercase of the commands, Octoprint does not. I will use Octoprint from now on.

I'll report the problem on the DWC bugtracker.

Maybe one final hint for people searching how to operate manual steppers, as this gave me a lot of headdache and was non-obvious to me and others even after reading the docs extensively:

The correct syntax for manual steppers is: [manual_stepper cutter] [tmc5160 manual_stepper cutter]

and NOT as some people are led to believe: [tmc5160 cutter]
