@karrad Checked again and it sends correct data to engine now, not sure why files are identical.
@karrad Set blank profile for global quality, so now extruders use only their own values. But now some values that are not overridden in extruder profiles can be set to default values from fdmprinter.json

@Steven Tried to add some delays and disabled serial in firmware, to check if if printer issues, but this don't help. Only way that I was able to reproduce this when I disconnected usb cable from pc while connecting, so it looks like communication issues. Also sometimes I was seen that printer hangs on load, so may be that issues can be connected, but I not see it now while testing.

@karrad Tried to reproduce this issue, but all attempts were unsuccessful. Used windows 7 on virtual machine hosted on ubuntu and taz 7 motherboard. Alse changed COM ports numbers for printer(3-256).
Can you please post log file and maybe some remarks on how to reproduce this?

@karrad Now should work. Also please check on all OS. It should default to:
windows: "This PC"

- min_layer_time is set for each extruder and time is counted also for each extruder in layer.
- force slowing of extruder was triggered only for last extruder in layer(fixed by above commit in T5146 branch). Now it counted for all extruders and should work.

@anolen @logan if minimum layer time is set to 0, there is also option called "Regular/Maximum Fan Speed Threshold" that alternates fan speeds.
Also there is no layer speed alternating, it's extruder speeds alternating(two extruders printing on different speeds, but it still one layer).
Cura changes extruders only one time at layer so it looks like:
layer1: E1 -> E2, layer2: E2 -> E1, layer3: E1 - > E2, layer4: E2 -> E1, etc... So changing speed happens when printer ends one layer with E2, and starts new layer from E2(and similar for E1).
If layer time goes below minimal value cura slows second extruder in each layer(for layer1 it is E2, for layer2 it is E1, etc) so you see that effect.
But cura not accelerating extruders it only slows it(in this case "faster speed = printing speed", and "slower speed = 30-40% of printing speed").
There is no need of changing engine algorithm(it's very hard), only need to set right combination of "printing speed", "minimal layer time" and "Regular/Maximum Fan Speed Threshold" to fix it.

function, which is a part of a system. So we can easily include only rambo driver to cura installer.

@karrad @marcio @logan Looks like it caused by "Minimal Layer Time" option, printer slow down second nozzle to get minimal 30sec that set in PLA profile. When I set it to 1sec for both extruders, all model is printed on the same speed. This bug don't happen on TAZ6, because this option is set to 10sec on it.

@karrad, I see scenario in engine code when this issue may happen, but can't test it, because it don't happen on my pc with dev cura and 3.6.4. Can you please post model files, settings, and instructions to replicate this issue, so I can debug it.
Jan 24 2019
@karrad Is there any test results on taz 7 with backlash compensation disabled? M425 is only command in gcode that applied on layer change and may change speed.

@karrad, found reason of this issue. In pla profile this option is set

@karrad Fixed position of z down
Oct 26 2018
@tutley, There is hard to find where is "new position" while exporting gcode from engine. Currently I'm in search of place in code, that controls it.

@karrad, The application works normally, looks like mac caching the process. Also this exist only in 3.x.x, can't replicate on 2.6.69. Looking deeper into it now.

@karrad, I reviewed code twice and found that we can add such mechanics

@karrad, by default
Sep 25 2018
@karrad, found a way to add z hops on this move. Please check if this solution is what we need.
Sep 21 2018
Sep 14 2018
@Steven @karrad While inspecting code I found that is very hard to insert z change command before this move. We can remove it and engine will work like in 21.08, but in this case combing option will not work while changing layers. Will we be satisfied with this decision or we need to find other solution?

@karrad, buttons and printers labels fixed. Merged to master.

@karrad, nozzle size is defined in extruder file, also toolhead should be inherited from base printer.
Jun 14 2018
@karrad It will be good only for custom user materials, but it can make problems for standard materials, because if we change some important setting in base profile - custom will be not updated.
Only thing that I can suggest is export base profile with user profile, but merge it only if this base profile is missing while importing.

@karrad Duplicating creates 2 files, for base profile and for extruder profile. The problem only in visibility, extruder profile used only by program itself and should be hidden.

@alexei, Seems like all octoprint features work as intended.
