I put on an extended z axis bar but when my print hits the 125mm limit of the shorter bar it stops going up any farther. I have firmware version 2.11on it. I put the version on before I had put on the extended z axis bar so I will reinstall it and see what happens. Has anyone else had the issue? What did you do to fix this issue? ---

Hi @jbrad2orr , In Snapamker Luban, you need to select the machine as `custom` and set Z(Height) as 221mm. ![image](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/c/c83d90be7941d330ce193b3a2e8b33914b473451.png) ![image](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/a/ae209bef7e1d9e5fe6e900e8001eff340c2aec9d.png) You can move the Z to 221mm height via the software. ![image](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/a/a9650c554395a5f1b67bbf99de5687ed3b3cb16d.png) Cheers Edwin ---

Thanks, Edwin. However, I don’t use Luban yet because it is not as advanced as Cura. I did set cura to the 221 but it isn’t working. I just reset the firmware and then checked the ‘about info’ on the machine. it still says the build area is 125-125-125. So I don’t have a lot of confidence that worked. Snapmaker needs to make Luban a lot better. ---

Did you [tell the firmware](https://support.snapmaker.com/hc/en-us/articles/360041448853-How-to-set-up-the-Z-axis-Extension-Module-) (step 3) about the new Z height? ---

Hi, clewis Thanks for that. I did the change. I also used Luban to generate the G-Code. If it works I’ll try the G-Code from Cuda. Got my fingers crossed. ---

Can you jog above the 125mm height using the control panel? From what I recall, the machine’s build area is supposed to report the higher Z axis after the `M1025 M1` command. (I don’t have one, so I can’t test it.) ---

There is an about page that shows all the attributes of the machine. After I reset the console it showed the new build area. Yeah!
