Hi all.

I have a fork of the Snapmaker controller firmware that I use for printing at high-speeds (basically the high speed printing beta firmware). I’ve used this for printing successfully for a long time. Recently I had to do some CNC work and that was not so successful: small jobs go well, large jobs don’t. I looked into the logging a bit and figured out that input shaping was also being applied during CNC jobs, which causes it to freeze during a large job. Unfortunately the Snapmaker firmware is a bit of a spiderweb and I could not reasonably separate the input shaping from the CNC & laser operations.

So my plan B: just have a firmware for CNC & laser and one for 3D printing with the input shaper. I don’t switch that much so it’s not too big of a hassle. Except: something in the Snapmaker HMI (supposedly) enforces that the new firmware version # must be higher than the current, so I cannot simply put two .bin files on a USB stick and switch them around.

I don’t want to update a number and recompile the firmware every time I swap toolheads, so I was wondering whether anyone knows how to force a firmware update or how to disable the firmware version check?

I don’t know the [quote=“Mayco, post:1, topic:34222”]  
Snapmaker HMI (supposedly) enforces  
[/quote] but there were big changes in firmware and luban which have to be up to date both for correct processing:

> [@Laser cutting - Laser didn´t shut off between objects](https://forum.snapmaker.com/t/laser-cutting-laser-didn-t-shut-off-between-objects/33989/2):

> Update the firmware of your machine to the latest, or at least version 1.17.17. There was a change implemented in Luban 4.9.0 and 2.0 firmware 1.17.17 to enable inline power control. Any lower version of firmware and the laser does not turn off.

I guess it’s only a warning message?

> [@Snapmaker Luban Downloads and Updates](https://forum.snapmaker.com/t/snapmaker-luban-downloads-and-updates/4949/40):

> v4.9.1

> Note: Since this version of Luban fully supports **inline mode** on the laser, this requires **SM 2.0** and **Artisan** to upgrade their firmware to the latest.

Don’t have a picture handy unfortunately, but when I try to install firmware with a lower version number than the current using the HMI, it just says “firmware is up to date”. If I then increment the version number, recompile the firmware, and try again it installs correctly.

This happens even when using USB stick? - Interesting, never saw that but it’s a while ago since downgrading…

@Jade I’m wondering if you can give some input on this, or forward it to the software team? I assume they run into the same issue… If this needs to be a support ticket I can also create one.
