When start a print the z axis goes up indefinately after homing
-
@Veti
thanks for pointing that out. I will try that and get back to you. -
I believe I have gone through and made the appropriate changes but i am still having the same issue. I think it has something to do with incorrectly setting the Z endstop. I am using a Pinde v1 probe for the z endstop which works correctly for the homing. Below is my new config.f

You still have the M584 command too long in your config. Move it up so that it's just below the M569 commands.

I have made all the above changes and it still goes up after homing.
-
I don't see anything in there that would cause it to do that. Either I'm missing something or the gcode posted isn't actually the gcode being executed. Can you post a screen shot of your folder structure on the SD card? Sometimes files can get misplaced.
It's only when starting a print that it does this, correct? You can home manually and it will behave correctly, but as soon as you start a print it homes and then continues to go up?
Can you post a video?
Now that you've moved M584 to the right place can you send M98 P"config.g" again?
-
Hello,
Yes, its only when starting a print that it has this behavior. I can home everything normally. Also, it performs a home before in the gcode before it goes up the z axis.
Here is the M98
M98 P"config.g"
HTTP is enabled on port 80
FTP is enabled on port 21
TELNET is disabled
The other bit to look at that I just found that I had not seen before is this start.g file. I think the issue may reside in here.
Is the start.g necessary?; 0:/sys/start.g

From the start.g
G1 Z160 F300 ; [BLTouch] Last chance to check nozzle cleanliness.
So maybe instead of hitting the estoppel actually wait and see what happens.
-
ok, im the idiot. Thanks so much for the help. the issue was the start.g and me not letting it go all the way up in the z axis. I have a print running thank you all for the help.
-
I should have requested the start.g as well. It's just not used very often by many people. Usually if someone is using it, they know what's in it. In this case it's a received config set which I should have looked more closely at. Uploading the full sys folder would have been my next check.
