Printer dosen't start the print job correct

Phaedrux

Did you recently update your firmware? What version were you running previously?

Error: G0/G1: insufficient axes homed

That would indicate that you were using a version older than 1.21 before?

From the release notes of 1.21:

On Cartesian and CoreXY printers, normal G0 and G1 moves are no longer allowed before the corresponding axes have been homed. In particular, if your homex.g, homey.g and homeall.g files raise Z a little at the start and lower it at the end, you will need to add the S2 parameter to those G1 Z moves. Otherwise the G1 Z move will be refused unless Z has already been homed and the homing macro will be terminated. If you want to allow axis movement prior to homing, put M564 H0 in config.g.

I think this may resolve your problem. You haven't posted your homing files so I can't tell if you have S2 added to your G1 moves or not.

I was before on 2.01 RC

My homing file looks like this:
https://pastebin.com/dAjNUw6Y

after this procedure it shows all Axis are homed.
I think it could be the stall detection that causes that Problem but i'am not shure.

Ah I see. In that case homing failing is not your issue.

Perhaps try using the 2.01 full release, to eliminate a firmware issue with 2.02 Release candidate.

Also, looking at your start script:

G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
M107 ;start with the fan off
G28
G92 E0 ;zero the extruded length
 
; ---D-Bot no Probe start
G29 S1
;G32 S2
 
; --Purgeline Script start at 20x and 20y and move 80mm while prime the nozzle
G1 Y20 F5000
G1 X 20 Z0.150 F5000
G1 X60 E10 F500
G1 X100 E13 F500
G1 Z0.20
; --- end
 
G92 E0 ;zero the extruded length again
G1 F9000
;Put printing message on LCD screen
M117 D-Bot Printing...

It looks like you are in Absolute positioning mode (G90) when trying to do your purge line, when I would think you would want to be in relative positioning mode (G91). The same question applies for your extruder. Do you intend to be using relative extrusion (M83) or absolute extrusion (M82) with the slicer?

Have you tried disabled stall detection yet?

@phaedrux
If i disable stall detection nothing works anymore cause there are no physical Endstops anymore.

The positioning for the Nozzle is absolut yes (G90) and the Extrusion aswell.
BTW. i got the issue on 2.01 aswell so i thought maybe it is fixed in 2.02 but i remember that i printed with 2.01 so maybe my
Slicer(Simplify 3D) is differten than my last (before Windows broke).

Strange cause i used the last gcode to configure my profile correct. (on every gcode it lists as a comment the configuration of the Profile).

//Edit:
Ok a old gcode File that i found on my printer works so it is my Profile that has a issue BUT there is a nother Problem:
23:15:28Error: motor phase A disconnected on drivers 2

It posts this every few seconds:
23:18:11Error: motor phase B disconnected on drivers 2
23:18:06Error: motor phase B disconnected on drivers 2
23:18:01Error: motor phase A disconnected on drivers 2
23:17:57Error: motor phase B disconnected on drivers 2
23:17:17Error: motor phase A disconnected on drivers 2
23:17:07Error: motor phase A disconnected on drivers 2
23:16:21Error: motor phase B disconnected on drivers 2
23:15:44Error: motor phase A disconnected on drivers 2
23:15:38Error: motor phase A disconnected on drivers 2
23:15:33Error: motor phase A disconnected on drivers 2
23:15:28Error: motor phase A disconnected on drivers 2

It is connected btw.
What can/should i do?

Found that so it is a Firmware Thing that i can ignore in that Version (it looks like)

Those look like spurious error messages that are a known issue in the 2.02 RC release. Go back to the previous 2.01 full release or the 2.02 beta release and try again.

If it dosen't damage my Printer or do something else it dosen't matter right?

The spurious messages don't matter. If you were getting them on just one phase then I would suggest you have a genuine problem; but getting them on both phases when the motor is moving slowly (e.g. the Z axis moving just a little to do bed compensation) is not unusual in this release candidate.

In previous releases, the open load detection has been disabled because of spurious indications. I was hoping to get it working in this release to help diagnose bad motor connections.

AS-3D Druck

@dc42 and what could you say about that my printer starts and stops after my purgeline and home it self?

dc42

@as-3d-druck, I would need to see an example GCode file that causes that behaviour when you try to print it.

AS-3D Druck

@dc42 Ok, here is the Thing that i tryed to print: https://cloud.as-3ddruck.de/index.php/s/pcfzPngPzMj3c3e

I think I see your problem.

From your gcode file:

;Put printing message on LCD screen
M117 D-Bot Printing...
G92 E0
G1 E-5.0000 F3600
G1 Z1.000 F1002
; process dbot
; layer 1, Z = 0.200
M104 S0 ; turn off extruder
M140 S0 ; turn off bed
G91 ; use relative coordinates
G1 Z0.6 F5000 ; lift nozzle by 0.6mm
G90 ; use absolute coordinates
G28 X0 ; home X axis
G1 Y100 ; move Y axis to end position
M84 ; disable motors
M107 ; turn off fan
T1
; tool H0.200 W0.408
; skirt

Right before starting the skirt under the heading process dbot layer 1, it disabled your motors and turns off the heaters and fan. It looks like maybe your end gcode script is being inserted into the start of your file.

Why does my Slicer this?

Phaedrux

Simplify3D? Check your various gcode insertion areas. Maybe something got copy and pasted into the wrong place?

Did that anf for some Reason i got the Endscript in the Toolchanging Section in S3D but i don't know why it was there.
Anyway thx for you're help.
Printer is now back in the Game.

Glad it got sorted out.
