Initial print cancelled
-
Hi all,
I just converted a tripodmaker to a Duet3D powered machine. Everything went well so far and I am loving the platform, however I can't manage to get my first print going ;).
Everytime I try to start my first test print I'm getting this message:
I don't really understand the order in which the Duet board executes all files.
What I am trying to do:
- start heating up the bed and nozzle
- home
- auto calibrate
- start print
I added a start.g file which contains:
G28
G32In my config.g I added M564 H0 in the end.
What am I doing wrong?
Thanks in advance

It would really help if you posted your config.g, homeall.g, bed.g and the file you're trying to print. Also include what duet you have, what kind of printer it is, what firmware version you're using.
Have you tested your homeall.g (G28) and bed.g (G32) separately?
Using M564 H0 and having something misconfigured in your homing or calibration files could place the head somewhere where it shouldn't actually be. Or perhaps you have a move that is physically impossible. At least that's what the error message is saying.

Thank you for the response!
Here is the info:

You forgot bed.g.
So because you have start.g it will run that file first, which runs G28 (homedelta) and then G32 (bed.g), and then it carries on with the sliced gcode file, which also has a G28 in the slicer start gcode. Depending on what you have in your bed.g you probably don't want that second G28 in the slicer start gcode because you've already done it in start.g
Until I see bed.g I can't really say more about what's going on.
What does your printer actually do when you start the print? It seems like only 2 seconds pass between you hitting print and it saying it can't reach a physical position. Does it move at all? Does it home to the top?
Also, do you have a zprobe? What is it? Do you ever call it in your bed.g to find the position of Z0?

Thanks for the reply. I found the issue that made the print cancel, it was the last G1 command in my homedelta.g: G1X0 Y0. For some reason this is seen as a unreachable move. I took it out since the print head should be centered after homing anyway.
I have a npn conductive Z- probe. What do you mean by using the z-probe to find z=0, that's what happens when I run G32 right? Doesn't it calculate the delta height using the given z-probe trigger distance?
If you have time please have a look at my other topic about calibrating this delta machine, that's where I really got stuck.

G1X0 Y0. For some reason this is seen as a unreachable move.
Probably because it would require a carriage moving up past the end stop. Would probably need to lower all the towers a bit in the Z direction and then it would work.

I'm not sure, I haven't seen your bed.g yet.
