Problems with updating firmware to 1.x (Solved)

Troubleshooting
1

Greetings

I’ve been a Maslow user since the first version. When I saw the announcement about maslow4 on Kickstarter, I knew I had to get this too.

It’s a great device, fairly easy to assemble, and I must say, very pleasant to use!

Now I had some time and I’m trying to update the firmware from 0.87 to 1.0. For some reason, I can’t get it to work.

I get the following error message: “line 45: esptool.py: command not found esptool failed”

• USB data cable checked
• USB port checked and tested on several ports
• Computer Macbook Pro
• 4.0 maslow

The first time I followed the instructional video and ran the full install file, it may have run the program through. I didn’t follow exactly what it did :slight_smile: I turned on Maslow and it still showed 0.87 firmware.

I tried to run the program again and then got the error message above. I tried downloading a newer version and got the same error message.

I googled a bit, searched the forums, and couldn’t find a solution, so it’s time to turn to the Maslow community.

Thanks in advance!

You need to update via the USB port. It may require you press and hold the button on the control board (under the fan) while starting the download. Make sure the USB cable is a data cable, some only supply power.

Download the software from the firmware site for the version to suit. Suggest you start with v1.12, initially. The following video is helpful

Thanks for your reply Ian. I did the installation according to the YouTube video. USB → Power on → Holding down Boot button → Power off /On → Running the update file.

I tried again with version 1.12. Same error message.

fluidnc-maslow4-1.12-posix/full-install.command ; exit;
esptool.py --chip esp32s3 --baud 921600 dump_mem 0x3ff5a018 4 SecurityFuses.bin
./tools.sh: line 45: esptool.py: command not found
esptool failed

:thinking: I wonder what I’m missing?

I dusted off my old PC laptop and tested it. The update seems to have been successful without any problems.
:partying_face:

Hopefully I’ll be able to test it next weekend.

the esptoool is not installed on your system. tools.sh is supposed to try and
install it but isn’t on your system

there should be a .something directory in your home directory that tools.sh is
using to decide if it should try the install or not .fluidnc or similar. try
deleteing that directory and reinstalling it.

it’s mentioned in the tools.sh file, but I’m traveling this weekend and can’t
quicly check what it is.
