@Dennis_kim HF020 Pulse Driver Speed Motion Controller

It's an external board, but it is the best solution to make it act like a spindle, could be controlled with a digital output/heater/fan output. I believe @dc42 said that this was potentially a feature to be added in 3.5, but I think it might not be ready in time (as well as feed hold, which is also useful in places where you have a spindle).

@Dennis_kim said in How to adjust the current of the heater connected to OUT0:

Is there any command to adjust the current of OUT0?

No. The current (I) draw is set by the resistance (R) of the heater, and the supply voltage (V), in the equation V=I x R. So I = V/R

Check the resistance of the heaters using a multimeter. What voltage are you using for each heater?

P.S. I don't know how to reply to a post... Sorry for posting something similar

You probably need to confirm your email address, which is required to reply in threads. Please don’t spam the forum with multiple new threads.

@Dennis_kim Have you already done a PID tuning?

The title should be in English so you can get help. At first I thought it was spam.

You can configure segmentation to break up long running moves into shorter segments which have a window of interruption between them.

See M669 S and T parameter

@Dennis_kim said in stop during operation:

Or, I want to create a function that moves the X/Y axis with the left/right/forward/backward buttons. What command should I use?

I'm not sure what you're actually looking to do. Can you give some more detail?

Are you able to ping the Duet IP address from your PC?

Also see this guide on setting up a direct ethernet connection.

If your windows / arduino can generate HTTP you can use https://github.com/Duet3D/RepRapFirmware/wiki/HTTP-requests. This is quite a straightforward interface, e.g. a GET of http://11.22.33.44/rr_gcode?gcode=G28 will execute G28 (ie home all) on the duet machine at 11.22.33.44. It has file operations (upload, download, list, delete etc.), execute arbitarray gcode, and let you get any part of the object model (which lets you check almost every element of the state or status of the machine).

If you install curl you can do this from pretty much any scripting language (even .bat files).

If you have a Pi connected to the duet device there's also the DSF: https://github.com/Duet3D/DuetSoftwareFramework This will let you do anything the duet can do, but requires more detailed and particular programming knowledge.
