@heartleander81 said in Issues after prime:

should I use the g-code in the same way or turn the temperature on again and turn off cold extrusion?

You can try it with heating first if you like. If the problem occurs, try simplifying the file as much as possible until you find a very simple test case. As part of this simplification, you could copy the contents of startGcode into the test file instead of calling it with M98.

LINE 14 and 28 is comment out. You See on the end ;SB
That is the Code who run without issuse

@heartleander81 thanks! If you reinstate line 28 and comment out the M150 lines and also the G32 line, does the problem remain?

Heartleander81

@dc42 have I do. The issuse is back

Heartleander81

@dc42
You said that the following axis suddenly causes problems after the extrusion? Then I think of a "misprint" that I made with the toolboard. The paragraph should not be but a plan. See the following picture

Heartleander81

ok i misunderstood something. I will gradually comment out and test each line from top to bottom.

Heartleander81

With line 14 have I the issuse and without is all ok

@heartleander81 thanks again. What about lines 17 and 20: if they are commented out and line 14 reinstated, does the problem occur?

Heartleander81

@dc42
After I comment out Line 20 its all good

dc42

@heartleander81 thanks again!

Heartleander81

I was able to issolate / fix the error by going to Z0.3 in line 14 with the long code.

I also tested things at the same time. Maybe that will help you

Heartleander81

@dc42 Thank you very much for your effort and patience with me.

Thank you for testing!

Heartleander81

@phaedrux
very gladly. I work as a department service employee in a company. So I know how important troubleshooting and testing are.

@heartleander81 unfortunately I still can't reproduce the problem. I've run it with and without line 20 (the T0 command) commented out, and analysed the moves in both cases. The only difference between them is that with line 20 present, there is a slight pause at that point, because RRF will wait for all preceding moves to complete and then wait until a few moves are in the queue (or no more are forthcoming) before executing the next one.

The effect of changing line 14 to Z0.3 is that line 24, which was previously a null move, is now a move in Z. So the problem may just have moved to the Z axis.

If you have time, please can you revert to the file that you posted in this post https://forum.duet3d.com/post/246160 that did show the problem, then check that it still does. Then replace the T0 command in line 20 by M400 and check whether the problem persists.

Please also try the effect of commenting out line 24 (the null Z move) just in case it is having an effect.

Heartleander81

@dc42 I like to do

Heartleander81

@dc42 Using M400 instead of T0 is the same problem

Thanks! so tool change is not part of the problem.

Does the problem still occur if you comment out the G1 Z0.200 F600 line 24 ?
