End Script driving head into model - Firmware 2.6.2 update - S3D - UM2+

Recommended Posts

I have been using this end script for a while in Simplify3d with my UM2+, in order to lift the head before it moves away from the print. Since the firmware update, it raises the bed, driving the hot end into the print, rather than moving it down away from the model.

Am I missing something obvious? I haven't changed any other settings.

G1 Z+20; lower the bed a bit

G1 E-20 F1000; retract a bit

G28 X0 ; home x axis

M104 S0 ; turn off heaters

M140 S0 ; turn off bed

M84 ; disable motors

To be honest: i strongly doubt that it is related to the firmware update. You probably don't want to move the z-axis to the absolute position of 20 mm, but a relative move instead (and similiar for the E-axis). The obvious thing is, that your end script does not (longer?) begins with the G91 command.

In addition it would be a good idea to switch back to absolute positioning at the very end of the script (with G90).

Good luck!

Hi Tinkergnome,

I thought it was relative move, Z+20, rather than the absolute, which would be Z20?

However, that said, I completely forgot about using G91. Will give it a go!

Cheers,

Dave

Thanks - I made the mistake of resetting my S3D when I upgraded to 4.0. Since then at the end of the print, the machine just stops, nozzle in the material still and the LCD and LEDs go dark like the thing crashed. It's done this on both short and long prints...so I think it's the end script.

 

Here's the original end script from S3D:

G28 X0 ; home the X-axis

M104 S0 ; turn off heaters

M140 S0 ; turn off bed

M84 ; disable motors

 

Not sure why it isn't doing the G28...

 

I just copied/pasted @jockspice end script so hopefully that does the trick. (Also been running Tinkerware for a few years now...wouldn't recognize the factory screens anymore!)

 

Thanks!!!

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
