rfm - RepRapFirmware FileManager [duetbackup successor]

[fma]

I'm trying to use your script, but I always get 'invalid character '<' looking for beginning of value' error. What am I doing wrong?

I'm using the amd64 version...

Thanks.

[wilriker]

@fma This happens if the Duet responded with an HTML error page instead of a JSON error. I've seen this happen more often recently but so far have not found the cause.

Are you using the latest v1.1.0 final release above?

Also which sub-command does this happen for? Also you can use the parameter -debug to see the actual response coming from the Duet. This might give a hint what's going wrong.

[fma]

Yes, I'm using the final release.

The error happens with all commands, and -debug does not give much info:

./rfm ls 0:/ -debug

0::
2019/08/18 12:52:40 invalid character '<' looking for beginning of value

BTW, does it require a specific version of RRF? Im' running 2.02RC2...

[wilriker]

@fma It should work with any version of RRF. Though the -debug parameter has to come before the location to list (in this case) or more general: before any parameter that does not have its own -something prefix.

[fma]

My bad, I made a mistake in the device name! All seems to work fine

Thanks for your help.

[wilriker]

@fma I'm glad it was that simple.

[wilriker]

Release v1.1.1

v1.1.1 has been release and can be found at GitHub Releases page.

Changes

• New -debug option to output the HTTP requests being sent to RRF
• Add CRC32 checksum as HTTP header to file uploads (supported by RRF 2.04RC3 and newer).

@wilriker Is it possibble to upload a file and start the print?

Best

[wilriker]

@PCR No, this is not a feature of rfm. It was and is intended to manage files on the SD card but not further interaction with the RepRapFirmware.

[PCR]

Ah OK. Thank you! BTW will it work with an DUET3 with a PI?

Best

No, it won't because in that setup the files are located on the RPi and for Linux there are much better file managers than I could ever come up with.

[oliof]

It would be nice to have rfm support RRF3 with SBC for consistency's sake though (-:

[tristanryerparke]

@oliof I second this

I was just directed to RFM for backing up our Duet. Thank you to @wilriker it's amazing!

However, getting it started was a little slower than it needed to be. If you are on Windows and looking for a way to backup your Duet, here is a quickstart guide / manual that might help speed things up for you. (The guide may help if you aren't on Windows, but you'll need to adapt file paths etc as appropriate).

Download and unzip to C:\Users\YourUserName and name the folder 'DuetBackupRFM'
  
Open Command prompt (Start - cmd - enter) which will open at c:\Users\YourUserName

Chang the cmd prompt folder to the one you just unzipped to: 
Type: cd DuetBackupRFM 		; and hit enter

Now you are ready to use RFM to backup your Duet. Read below. 


RFM Duet Backup Commands: 

**note: must use program name, command name, then can use options and parameters/arguments.  
**ONCE a device has been specified (a device profile is created on first use), you can refer to the device without networking options by using the device name. 


RFM Command Syntax Explanation: 

Valid Example command: 
	rfm backup -device YourPrinterName sys 0:/sys

Explanation: 
	rfm 		backup 		-device 	YourPrinterName 	sys 			0:/sys
	program name	command name	option name	parameter for option	local comp. folder to save to	Duet folder to do command to


Things you likely want to do: 

STEP 1. connect to the Duet (creates a config for the Duet as the -device name) and list The Duet's root directory: 
	rfm ls -domain 192.168.1.12 -port 80 -password YourDuetPassword -device YourPrinterName

STEP 2. Backup the sys folder on your duet (already created in step 1 in RFM) into a folder on your computer called 'sys' (which will be located in the same folder RFM.exe is located). 
Note: RFM will create the folder on your computer if it does not exist. RFM will also use UNC / absolute paths if preferred (so you can redirect outside of the RFM folder - see examples at end). 
 
	rfm backup -device YourPrinterName sys 0:/sys

STEP 3. Backup the macros folder for your duet (already created in RFM) to a local 'macros' folder: 
	rfm backup -device YourPrinterName macros 0:/macros

STEP 4. Backup the filaments folder for your duet ((already created in RFM) to a local 'filaments' folder: 
	rfm backup -device YourPrinterName filaments 0:/filaments

STEP 5. Backup the gcode files on your duet (already created in RFM) to a local 'macros' folder: 
	rfm backup -device YourPrinterName gcodes 0:/gcodes


- - Some other Examples: - - 
List all the files in the folders in the root of your duet: 
	rfm backup -device YourPrinterName

List all the files in the sys folder on your duet: 
	rfm backup -device YourPrinterName 0:/sys

List all the files in a folder on duet with spaces in its name: 
	rfm ls -device YourPrinterName "0:/macros/calibration/bed leveling"

If you are using spaces in your RFM backup path or on duet - enclose in quotation marks: 
	rfm backup -device YourPrinterName "C:users/yourusername/DUET BACKUP RFM"  "0:/macros/calibration/bed leveling"

Write script for bash (GNU/Linux) to backup all files.

#!/bin/bash

# ---------------------------------- Parameters -------------------------------------
temp="temp"											# Temp folder for backup
output="backup_rrf_$(date +%F_%H-%M-%S).tgz"		# Archive name for backup

# -----------------------------------------------------------------------------------
mkdir -p $temp										# Create temp folder

./rfm ls | while read line							# Parse list of files and folders
	do
		if [[ `echo "$line" | grep "\[f\]"` ]]		# Processing files
			then
				filename=`echo ${line##*	}`
				./rfm download "$filename" "$temp/$filename"
				echo "$filename - File downloaded"

		elif [[ `echo "$line" | grep "\[d\]"` ]]	# Processing folders
			then
				foldername=`echo ${line##*	}`
				./rfm backup -exclude overlays "$temp/$foldername" "$foldername"
				echo -e "\n"

		else echo "$line - Strange line"
		fi
	done
		
tar czPf "$output" "$temp"							# Create archive
rm -rf "$temp"										# Delete temp folder

I am trying out rfm. I go into the folder that has rfm in it and do:
./rfm backup -domain 192.168.1.163
this backs up the /sys folder on the duet card that is at 192.168.1.163.
If I want to back up the macro folder on that Duet, what should the command look like? Based on the help section of rfm, I was trying ./rfm backup /macros -domain 192.168.1.163 but I get 'directory not found'.

Hi @wilriker

This is a great project and I would like to implement it on my system, but I (generally) manage the system remotely.

Specifically, I have a Mac (in the house) and use the Microsoft Remote Desktop (RD) app to connect to my Surface Pro (in the shed), via a wired network, which is hard-wired to the Duet3 MB6HC control board running my CNC machine (I don't run the CNC machine remotely, before anyone asks!)

The first question I have is, should I install rfm on the Mac and run it from there, or install it on the Surface Pro and run rfm from the Mac (via RD), and the second question is, which version should I use if it's installed on the Mac?

I'm running RRF version 3.4.4

Thank you

You need to switch the order of parameters:

rfm backup -domain 192.168.1.163 <local-path> 0:/macros

Note that local-path is mandatory if you specify a remote path.

Actually this just depends on what is more convenient for you. As long as rfm is able to connect to RRF via network this does not matter.

I personally would probably install it on the Surface Pro just because it is closer. But again, it just boils down to what is more convenient for you. Mine is installed on a Raspberry Pi that is lingering around somewhere in the house and runs a background task that periodically checks if it can backup anything or not.

If you want to install it an the Mac use darwin binary. Although this will not work on a M1 MacBook. When I compiled rfm the last time there were not M1's around AFAIR.
