M92 to set extruder Esteps individually in a dual config
GrodanB last edited by GrodanB
Reading the g-code reference for M92 it seem that I cannot set extruder T1 to one value without setting T0.
Is that correct?
Looking for something like M92 E0:xxx E1:yyy or more backwards compatible: M92 Exxx: to only set T0 and M92 E:yyy to only set T1 . (the "missing" number is unchanged... and expandable to as many supported extruders there is)
For me I would like to have a filament setting per extruder in DWC. Or even nicer one that let me choose to which extruder the settings should be applied...

@GrodanB No, it should already work as you want. In fact if you look at the second example, it shows exactly that - i.e. M92 E420:500.
When you specify extruder step values for multiple extruders you use just the one "E" then separate the other extruders by using a colon - as in that example. So M92 E420:500 not M92 E0 420:E1 500.
Also be aware that Tn refers to a tool, not an extruder. Extruders are drives and treated like axes, tools may have one or more extruders assigned to them.
Edit. Also for info, I have a CoreXYUVAB with 6 extruders so my M92 looks like this:
M92 X80 Y80 U80 V80 A80 B80 Z3200 E409:407:405:405:403:405

But I just want to change one extruder...
So I have today: M92 E417,5:408,30
This sets both my extrudes to their separate numbers... what if I would like to change the second one but not the first? but since I do not "know" (my filament script) which filament is loaded on the other extruder I do not want to change that value at all. I like to set it loading a filament to the tool in DWC.
I have found that for each filament I need a slightly different setup...so I would like to be able to set it ONLY for extruder 2...
or am I missing something fundamental here...
So you want to change the steps for the second extruder without having to know/change the steps for the first extruder. Not sure that's possible.
However, rather than adjust the steps per mm why not use the extrusion factor?
That can be targetted and has the same effect.

@GrodanB As @Phaedrux has pointed out, it's generally best to calibrate the extruders using one filament. This will allow for diffences in the diameter of the hobbed bolt and/or extruder tension. When this done, do not change the steps per mm. Instead use the extrusion multiplier to make adjustments on a per filament basis.

OK, that is not how the "manual" for my printer taught me to calibrate...
So I'm a little slow... But as you say, it should be equal to changing the esteps but possible to control per extruder.
Thanks I think I understand now.
