Posted · Weird behavior of "Pause at height" script with UM S5

Hi to all

I have implemented a "pause at height" in a print job on an Ultimaker S5, but I noticed some weird behavior.

The S5 is a 1st Gen printer running last 7.X firmware.

 

Here's the script generated

 

;added code by post processing 
;script: PauseAtHeight.py 
;current layer: 635 
M83 ; switch to relative E values for any needed retraction 
G1 F300 Z66.6 ; move up a millimeter to get out of the way 
G1 F9000 X320 Y230 
M104 S0 ; standby temperature 
M0 ; Do the actual pause 
M109 S220 ; resume temperature 
G1 F9000 X216.454 Y121.439 
G1 F300 Z65.6 ; move back down to resume height 
G1 F1800 ; restore extrusion feedrate 
M82 ; switch back to absolute E values

 

So it should park the printhead in the back right corner, set the temperature to 0 then pause the print. After the resuming, it should reheat the Hotend to 220 and wait to stabilize. No extrusion move should be done (there was already a retraction at the end of the previous layer.

 

The actual behavior is the following :

- printhead is moved out of the part, then to the front left corner

- temperature is set to 0 in the meantime

- print job is paused

- when resuming, a extrusion move is done, though the Hotend is cold -> severe grinding causing no extrusion when resuming.

- printhead is moved to the back right corner

- temperature is set to 220°C and wait to stabilize

- printhead move to the last printing position

- print job resumes.

 

To make it short the pause is not usable.

 

Quick feedback is appreciated.

    I found the problem : I was selecting the Marlin method instead of Griffin for an Ultimaker printer.

    Now it works fine. print head is parked on the front left corner and no unwanted retractions.

    Pause it seamless if using a second sacrificial object properly placed on the build plate.
