You did not say what happened other than the alarm

Your config section for the Z tells the machine to move down ( positivedirection: false) 33 mm (maxtravelmm: 30 * seekscaler: 1.1) to find the Z homing switch. It looks like your switch is mounted in positive Z.

“yaml
z:
stepspermm: 80
maxratemmpermin: 1200
accelerationmmper_sec2: 500
maxtravelmm: 30
soft_limits: true
homing:
cycle: 3
positive_direction: false
mpos_mm: 0
feedmmper_min: 300
seekmmper_min: 1000
settle_ms: 500
seek_scaler: 1.1
feed_scaler: 1.1
“

I just changed it’s the same
Can we run the engine without the safety devices?

#3 – MitchBradley 于 2024-12-18

Does the motor run in the correct direction – toward the switch?

If you issue a motion command like G0 Z10, does the z axis move the correct distance and direction (10 mm upward for that command)?

#4 – MitchBradley 于 2024-12-18

You can turn off soft limits with soft_limits: false. Is that what you mean by “without the safety devices”?

#5 – FMD14 于 2024-12-18

No you have to put 300 to move a lot

#6 – MitchBradley 于 2024-12-18

You need to set your configuration correctly. http://wiki.fluidnc.com/en/support/setup/motion#adjust-stepspermm

Read what the wiki says about configuration and adjust everything to match your machine.

#7 – FMD14 于 2024-12-18

my assembly is as follows nema 17 motor two G2 20 teeth pulleys with belt which drives a threaded rod of diameter 5 with a pitch of 1mm. When I exceed 800 mm the motor is not happy with the tmc2208 driver. How to calculate the steps with this assembly? To get 40 mm I have to type g0 z140. How to do it?

#8 – MitchBradley 于 2024-12-18

Go through the process at http://wiki.fluidnc.com/en/support/setup/motion step by step. Read everything carefully and make sure you do everything it says. If the motor is not happy with >800 it means that you are going too fast.

#9 – FMD14 于 2024-12-20

here is the new config file that works

Please consider sponsoring the project. Answering questions like these is very time-consuming.
