Suggestion for the Replace Toolhead Function  

Suggestion for the Replace Toolhead Function

Original Problem:

My 5 toolhead XL printer had 1, 2, and 3 set up for PLA and 4 and 5 set up for PETG.  I was printing a part that I sliced in PETG to use toolheads 4 and 5.  When I started printing, I had problems with toolhead 5, so I unloaded the PLA in toolhead 3 and loaded my PETG into that toolhead.  I made sure that the printer knew that toolhead 3 now has PETG and not PLA.

I then printed, but in the menu, I replaced toolhead 5 with toolhead 3.  Unfortunately, it would never print properly after many attempts.  I finally figured out that it must be using the wrong temperatures.

My Assumption:

I assumed that when I clicked the “replace” button on the screen of the printer, the printer would use the settings in the gcode for toolhead 5, but simply replace toolhead 3 for toolhead 5.

I now suspect that when I clicked the “replace” button, the printer replaced toolhead 5 for toolhead 3 but also used the settings in the gcode file for toolhead 3 which was set up for PLA.

If this is the case, can anyone please confirm it?

Suggested Improvement:

If a user selects the “replace” feature, it should be followed by another screen with two options:

• Replace the old toolhead with the new head and use the settings for the new toolhead.
• Replace the old toolhead with the new head but keep the setting for the old toolhead.

I feel this would give the user the ability to temporarily correct a problem at the printer without having to reslice a new gcode file. 

The way I had to correct the problem was to go back into the designer and change the properties of toolhead 3 to PETG.
