Remove U16 from this line (potentially confusing firmware):

Remove this line (unnecessary, potentially confusing firmware):

Woohoo! That seems to have been it - I'm now able to move all 3 axis again and again and again... Thanks a lot for the suggestions everyone!

Can anybody explain to me what the proper setting for M350 should be or how I figure it out?
And what is the purpose of M669? Why shouldn't kinematics be set to cartesian on my Workbee?

And last but not least; Does anyone happen to have a link to a full 3.4 config for a setup matching mine?

Hi,

Whenever I try to home the X or Y axis on my Workbee 1015, I'm getting the following error:

G28 Y
Error: G0/G1: target position outside machine limits

When starting up the Duet interface shows the coordinates being something like 0,-1270,-94.

Duet and firmware info:

Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.0 (2022-03-15)
Duet WiFi Server Version: 1.26

Having never used a CNC I think part of the issues stems from not understanding the coordinate system in regards to where the machine should be when it's homed and when it's in it's max position.
In my head it makes sense that the machine starts at 0,0 and then goes to 740,1200 (-ish) when it's at its max but I don't know if that is actually the case.

The machine is currently positioned like this, and I would like for the machine to home to the big arrow.

Here's part of my config. I hope I didn't miss something relevant.

@fcwilt said in X Axis stops working after moving Y:

I've never used anything but 16x on the axes and extruders and I1 to enable interpolation. The reason for always using 16x was the the boards I started with, Duet 2 WiFi, only supported interpolation for 16x.

16x it is

M669 K0 is a quick way of setting the X, Y, Z parameters for a Cartesian. You can use X, Y, Z if you know what they should be for a given kinematics. But having K0 and the X, Y, Z parameters is redundant and possible troublesome if the K value specifies one set of X, Y, Z values and you specify another set with the X, Y, Z parameters.

That makes sense, thanks for the explanation!

@fcwilt I have no idea what that is supposed to to. I can't remember adding it but I might have copy pasted a bit too much when I was setting up the dual Y axis.

I'll try to remove it as soon as I have a few minutes, thanks!

Another thing I noticed today: After moving the Y axis the motors will emit a certain high frequency sound while idling.
After a while that sound stops and then I'm yet again able to move the X axis.

@fcwilt Correct.
That was my first assumption as well. I checked and redid all connections but the issue is still there.
Also as mentioned - If I switch X and Z around, the problem moves to the Z axis and now the X axis works just fine.

Hi!

I bought a half-finished Workbee last year and I finally got it assembled and all 3 axis moving.
However after a short period of time - Often times as soon as i move the Y axis - My X Axis stops working.
The motor will just emit a "humming" noise instead. I uploaded a short clip of the issue here.

I tried flipping the connectors on the board for the Z and X axis and that moves the issue to the Z axis instead. This to me indicates a problem with the Duet board or my config and not the machine.

Bonus info: After the axis stops working I'm able to turn the screw with my fingers. The other axis are all "locked" when idling.

I found this post from someone with what sounds like the same issue and he got it fixed by updating the firmware. I was running RRF 3.3 before and updating to RRF 3.4 sadly didn't help.

Any ideas what to try next?
