Add Z-Hop support #8
Conversation
|
Dont have a printer in reach to test, but looks alright from this gcode visualiser (after also fixing #7): |
| gcode += "G0 F{speed} E{e:.6f}".format(speed=retraction_speed * 60, e=e - retraction_distance) | ||
| if retraction_hop_enabled: | ||
| gcode += " Z{z:.6f}".format(z=layer_heights[layer_nr] + retraction_hop) | ||
| gcode += " (RETRACT)\n" |

I think this is your debug code? Or maybe something specific to your device? Having the word (RETRACT) there is not standard g-code.

| gcode += "G10\n" #enable retraction gcode |
This seems to work for me
| gcode += "G0 F{speed} E{e:.6f}".format(speed=unretraction_speed * 60, e=e) | ||
| if retraction_hop_enabled: | ||
| gcode += " Z{z:.6f}".format(z=layer_heights[layer_nr]) | ||
| gcode += " (UN-RETRACT)\n" |

Similarly, this is not standard and would give a parse error in many printers.

this also works for me - ender S1 Plus - I think that G11 is right - in practice it is working on my printer - I know it is needed per marlin docs "Multiple consecutive G10 or G10 S1 commands without a corresponding G11 or G11 S1 will be ignored" so I would assume we're getting G10 / hop / G11 to close the loop.

I went though for a few hours (yes hours) - the G10/G11 were easy fixes to swap out and they work, my cura settings are set to 4mm z hop and .08mm retract. The issue I'm still having (and this is probably a different issue) and where I spent my hours on are it will essentially G28 X0 Y0 Z.02 at start of print (drawing?) and there is no way for it that I can figure out to stay hopped until the first correct X/Y and drop to .02. I've tried enabling prime, putting a G10 in the code prior to starting, changing "
and a few other things. Essentially it will start at that first layer height and stay there, which drags the pen across from the corner to wherever the drawing is, I can't figure out a way around it and everything I've tried either does NOT work or it causes cura to say the plugin is corrupted. |
