I have gone through all the steps in the calibration but when I get to cutting the test pattern Maslow just sits there in the center and does not move. I know stuff works cuz I went through calibrations up to this point.
Sometimes, when I click quit and get the message that says if you quit, all is lost and the zombie apocalypse will start, then is starts to move.
Why is is doing this. How do I get this to finish calibration?
Advice would be appreciated. Thank you
Bill
Here are some thoughts that might help.
Is the power cable plugged into the Maslow board (not the Arduino)? It provides power for the motors, but nothing else. The green LED next to that socket should be on if there is power for the motor. The green LED on the opposite corner indicated that the Arduino has power from the USB cable.
Is GC able to communicate with the Arduino? When it first starts, it prints āconnected on port ā¦ā. The calibration sequence doesnāt check for the presence of a connection before starting the steps.
If the Arduino is connected but the machine is uncalibrated, you might (should?) get a message when GC starts āUnable to find valid machine position for chain lengthsā¦ā does that come up? Not a problem, just another checkpoint on the way.
When GC first starts, can you make the motors move using the on-screen arrows? You might want to un-rig the chains from the motors for that if there is a danger that they could over-wrap or pull tight.
[Edit] - if there is no z-axis motor connected but the setting expects a z-axis motor, there is a several-second wait each time GC sends a movement command to that motor. It feels to the user like nothing is happening (GC shows āG0 Zxxxā in the terminal window though)
Let us know if any of this helps, or if there is more help needed.
Can you tell me a little bit more about your frame/sled combo (chains on top or on the sides? linkage kit? ring?)
It sounds to me like everything is working properly (Because like you said, you got that far)ā¦I canāt think of any reason that it would stop just there, but I am thinking on it!
Is z-axis installed and set that way in the settings?
How are the chains mounted to the sled?
Can you upload a copy of the groundcontrol.ini (home folder) and the log.txt Gc folder)?
I have the z axis kit but I do not have the coupler yet so I left the z-axis turned off. At least for now. I am attaching a picture of my setup. Chains are on the bottom. I have the latest ring with the V bearings. I have the Z-axis plugged into the board but if it is turned off in GC, would that matter?
Hope this helps answer your questions. Advice appreciated.

Hereās a pretty simple file. If you open it and press the green run button in GC, what happens? I would do it without a router bit in just to test, unless you want to end up with a cutout of some mountains
OKā¦stand by. I have another issue that popped up. I tried the test pattern again for the calibration after unplugging the cable for the z-axis. Again, it just sat there when I click to run test pattern but when I āquitā then the sled started to move but the chain started wrapping around the sprocket. See picture. Gotta figure out why it is doing this first I guess.
Darn! That is annoying! I havenāt seen that happen with the weight of the sled attached before.
It happens when the chain is new and stiff so it wants to stay on the sprocket more. Working the chain by hand will fix that, or it will just go away on its own with time. To unwrap it, I would disconnect the sled to take the weight off and then unwrap it by hand.
Ok I think I know whatās going on! Itās totally a bug on my end. Whatās happening is that a popup is opening to ask you to adjust the z-axis depth but itās being hidden.
