Works fine with windows 7 but not on windows 11 . Any ideas ? Device Manager shows Adrdino on comport 3.
Hello! I would like to welcome you to the forum! I havenāt received my MK2 yet but do have a Windows 11 laptop that I am planning on using. I am confident that someone here will chime in and provide the answer to your question. I would appreciate if you could post the solution to your problem. That really helps very much!
Be safe!

last night i was working with gsender, this morning i cannot connect to comm 3 or does not recognize comm 3, i have had this issue for awhile and all have to do is shut off my computer and restart, open gsender and all is fine , no such luck this morning
Hi there! I have switched computers to use my machine. My new machine runs Windows 11. It GSender loads just fine, but when it try and connect to my machine, i receive the error, error opening port āCOM3ā. I have uninstalled and reinstalled gSender multiple timesā¦ It simply wonāt connect. Is there with Windows 11? Iām pretty sure it is a āuser errorā issue, but whatever it is, Iām stumped. Any ideas? Thanks for the benefit of your experience.
@BadGolferBob Look at device manager in windows to see what com port your controller is connected to and choose that port in gSender. It may that gSender is remembering the port that you were using on your previous machine and it has changed with your new machine and windows 11.

This is something we might have to look into as a bug, still unsure since none of us have been willing to update to Windows 11 yet 
I havenāt solved the problem with windows 11 still using windows 7
I couldnāt get windows 7 laptop to even recognize or load the driver for my longmill. I switched to an OLD MacBook Pro and was up and running in 10 minutes. It is amazing to see the machine come to life!
Be safe!

In the forums there was a person having port issues, it was recommended to install the Arduino IDE and that helped it work.
I would start with that
So I guess Iām a glutton for punishment.
Iāve decided to install Windows 11 on my Alienware laptop
I will update once I get things moving and if thereās any problems Iāll advise here
So I just finished installing Windows 11 64bit on my laptop.
1 - Installed gSender, 64 bit (1.06)
2 - Plugged in my Arduino UNO (stand alone board purchased directly from Sienci.com)
3 - Loaded gSender 1.06 and it loaded no issues.
If you want to try and compare environments, let me know
Granted I donāt have my 30x48 yet, but this Arduino board is the same as in your machine.
gSender - [Grbl]
Connected to COM3 with a baud rate of 115200

ok
The hardest part about the upgrade was enabling TPM
took a few videoās to find that I needed to enable Secure boot for TPM to be enabled.
Hey Guys
Found answer to the cannot connect. In gsender under setting reset default gsender settings with
the long mill running and gsender searching for comport . Thanks to Jason@ sienci labs. up
and running now on windows 11.
