Position error, exceeded 15mm while running

beck.wright · July 2, 2026, 11:50pm

Finished calibrating. I’m able to jog, but it won’t even let me begin a dry run without giving me this error code. Im a complete beginner to all of this, so any help is appreciated.

Which firmware version are you using? I remember a bug like this a while back, but I believe that it should be fixed in the latest version.

beck.wright · July 13, 2026, 9:33pm

I was on 1.04 firmware. I updated it to 1.23… I think? I’m not sure what I did wrong, but now it won’t let me jog or do much at all. It also says “State: Unknown”. In addition, the green play button next to the red stop button is gone and blank.

ian_ab · July 13, 2026, 10:30pm

Save a copy of your maslow.yaml file if you haven’t already and replace it with the new version in V1.23. You will then need to rerun Find Anchors or manually update the maslow.yaml file with the Anchor point values from you existing maslow.yaml file.

Got to FluidNC
Click on Config Items
Go down to /kinematics/MaslowKinematics/tlX
Copy each value from your old maslow.yaml into the corresponding position in the new maslow.yaml
Set each value
go to top again and save

I recommend a power reset, then you will then need to retract, extend and apply tension

beck.wright · July 14, 2026, 7:44pm

Thank you for the quick response. I tried the things you said, however, I must’ve done something wrong. Because after 3rd time of attempting that process, I went to jog and the machine just started going straight down (I have it mounted vertically) with no sign of stopping until I unplugged the machine. Also, I’m not sure if this matters, but I’m doing all of this on a Mac. If you or anyone else has any answers, that would be greatly appreciated. Thank you

Stop Maslow and Gcode

ian_ab · July 14, 2026, 10:01pm

Do you have the control board upside down, The power cord must be pointing down when on a vertical orientation.
Also your index.html.gz is the old version. You will need to update it to the V1.23.
FluidNC
First Green button (Manage Local Files) and load the latest version of index.html.gz. On the Mac when you download it wants to unpack the file. You need to load the compressed (gz) version of the file. Try right click when down loading from resources.

ian_ab · July 14, 2026, 10:10pm

It is going to be the wrong version causing the problem
Can you put a copy of your maslow.yaml file up here please
Its very particular regarding the formatting

beck.wright · July 15, 2026, 3:29pm

The power cord is pointing down. I noticed that the index.html.gz is the old version. However, when I try to put the updated one in, it seems not to change anything. It must be because of what you’re saying about it wanting to unpack. The thing is, I read about that somewhere and tried to do what you’re saying, but I couldnt seem to get it to work. Also as I write this, the interface crashed and will no longer open. Not even when I search “192.168.0.1”. The light is a constant green and there are no blinking red or blue lights.

maslow.yaml (6.6 KB)

beck.wright · July 15, 2026, 4:04pm

These are what my screens look like when I type maslow.local and 192.168.0.1

bar · July 15, 2026, 4:57pm

No blinking blue light means that the machine is not connected to the wifi and is creating its own “Maslow” wifi network. You should be able to connect directly to that wifi network to get the connection back.

beck.wright · July 15, 2026, 5:34pm

I was able to regain access to the Maslow interface. I retracted/extended the belts. Put it back on my frame, pressed the apply tension button. Uploaded the gcode, however, my play button is non-existent. So even if I wanted to, I couldnt attempt to start it. I then pressed the square stop button, and it told me belt lengths were unknown.

It looks like the machine doesn’t have a good understanding of the anchor point locations. Running locate anchors or copying them over form an old .yaml file should fix that

beck.wright · July 15, 2026, 6:34pm

How would I go about this? The “find anchor locations” button is grayed out and I tried clicking it anyway and it gave me a message saying to make sure the Z is all the way lowered. So i go to lower it and it gives me a low z warning but lowers anyway. I got it lowered all the way to the point of it bottoming out, but the find anchor locations button is still grayed out.

ian_ab · July 15, 2026, 6:59pm

It looks like the versions now match. If you have the old version of maslow.yaml you can copy the position data as per the how I put up above OR
I suggest you start by

disconnectinng anchors,
click Setup
Retract,
Extend
Reconnect to anchors
Find Anchors

Thank you, this helped. I was doing the steps in the wrong order it seems
