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 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.
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.

./tools.sh: line 45: esptool.py: command not found
I wonder what I’m missing?
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.
Hello. I see the answer here says “you may have to press the button” on the control board to load with USB. “May” I load software without pressing the ‘boot button’? Something is wrong with my network config and MASLOW is not showing up now. Afraid I might have typo-ed something. Already did the full Monty thing, dismantling down to the control board to get to button for full reset (this after 4.1 upgrade install) once.
So, anyone figure out a clever way to push the button without taking it apart? (Or an update to ‘open the hood’ ., simple hinge on fan and cover, say?)
Is it necessary to push it to use USB to revise the CONFIG files? Can I edit the CONFIG files with the USB some way? What editor in Win11. Fingers getting too old to ‘play’ with all the nuts/bolts excessively - really fascinated with the way Bar just twiddles those screws in! Next time to ACE hardware I’ll pick up a few longer (SO pricey!) screws and see if that can help (making sure they don’t touch the board or interfere with the fan)
There are 3 screws which hold on the cover. Do not undo the 4 in a square, they hold the fan to the cover. You do need to undo the cover to access the button.
If you can’t see the maslow.local then it means it probably successfully did the update. Go to your WiFi and see if you can find maslow. You need to re-enter your wifi SSID and password (later versions you can do this in Config, under setup)
My usual not TMI (too much info), but NEI (not enough info) - the tip about the fourth screw is GREAT, sorry I missed that before. But as far as updating via CONFIG, lost the WIFI MASLOW and do.t see it anymore. I attempted to set network to home WiFi, not MASLOW local network, which is why I think I must have typo-ed the info for home WiFi some way. Now I’d like to get back in and make corrections. So the access is the problem, hence the desire to be able to connect and edit via the USB. Any way to connect directly and do this that you know of?
Is the blue LED flashing on the Maslow? If so, it has connected to your local network. You just need to find it. If you can login to your router you should be able to look for Maslow connected which will give you the IP address. Type that in on your browser in the address bar.
If you need to access via the WiFi, can you turn off your local WiFi and power reset the Maslow which will let you access the Maslow’s WiFi again. but I don’t think that is your problem.
To the best of my knowledge you can’t update that info via USB.
Surprisingly - at least to me - able to connect and edit CONFIG via USB. Cable needs to transmit data, and I find my USB that works with connecting my iPhone to PC works for this, too. So far, so good. Thanks for the help!
I turned on Maslow and it still showed 0.87 firmware.
