@dc42 I like to do

@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 ?

@dc42
Have it do, G1 Z0.2 F600 comment out problem is there

dc42

@heartleander81 thanks! So your file should look almost like this (I have commented out a few more commands that I don't think are relevant):

G90
M83
M302 P1 ;;dc
T-1 ;;dc
M106 S0
;;G4 S1 ;;dc
T0
M83
G1 X5 Y5 Z30 F6000.0 
G1 Y50 Z0.2 F3000 ;;after comment out this line looks out run without issuse
G1 Y90 E20 F300
G1 Y120 F1200
;;G92 E0.0
; process CR3D 0.4
; layer 1, Z = 0.200
M400 ;;dc was T0
G1 E-0.6000 F1200   ;SB

;G1 X280.511 Y53.567 E8.9768 F1800

Please confirm that the problem is present using this file, and not present if you comment out the M400 at line 16.

@dc42 yes with the code and the line 16 M400 the error is there and if I comment out the line 16 M400 the error is gone

@heartleander81 thanks again. My current theory is that the problem occurs when a move sequence (after e.g. M400 or tool change) starts with a move that doesn't involve the main board. If that's the case, then inserting any axis move command (e.g. G1 Y120.1) after the M400 line and before the G1 E-0.6000 line should avoid the problem.

Heartleander81

@dc42 Yes that is correct after M400 the command G1 Y120.1 removes the problem.

dc42

@heartleander81 thanks. Now I know where in the code to look.

Heartleander81

@dc42
I'm glad that I was able to help.
So do I understand correctly that it is caused by the toolboard?
If you've found something, I'll be happy to test your change.

I think it's caused by he first movement after a break (such as M400 or tool change) using only CAN-connected expansion boards. My best guess is that the start of the following move is not being scheduled correctly, for example the move is started late so that it has a lot of steps to catch up.. Unfortunately I haven't yet made the problem happen here, even though I used your config.g and the same test file; but now at least I can look at that area of code to see how the start of the second move is scheduled.

Please can you do one more test. Run M122 to clear the statistics, then run that test file that provokes the problem. Then run M122 again and post the result here.

Heartleander81

@dc42 ok. The file with issuse?

@heartleander81 said in Issues after prime:

Yes, without the G1 Y120.1 command.

@heartleander81 thanks again! I was looking to see whether there were hiccups after the problem occurred, but there are none in your M122 report.

Heartleander81

Oh in the M122 ist the board Version 1.01 but I habe 1.01A

Heartleander81

@dc42
I have no idea about programming or what RFF is capable of.
But I've read that you can write a debug file.
But that won't help either, otherwise they would have suggested it.

Should I make an M122 from the Toolborad?

I don't think that will show anything. The toolboard is working properly as far as I can tell.
