Extruder parameter format question

Phaedrux

Order dependence

M584 must come earlier in config.g than any M350 and M906 commands. If it creates new axes, it must also be earlier than any M92, M201, M203, M208, M350, M566, M574, M667 and M669 commands.

@Phaedrux I think I didn't make my question clear. Is there a way to set a single extruder (other than the first in the list)? If I want to set extruder 2 and don't want to change extruder 0 or 1, what is the gcode syntax?

Thanks!

You do realize that the required order of things, as mentioned, renders your approach unworkable?

@fcwilt , I don't see it yet. This is what I have so far:
; *** Tool 0 ***
M308 S1 P"spi.cs1" Y"rtd-max31865" A"T0" F60 ; PT100
M950 H1 C"e0_heat" T1 ; Heater
M143 H1 S390 ; Set temperature limit to 390C
;
M950 F1 C"fan_1" ; HE fan
M106 P1 S255 H1 T70
M950 F2 C"fan_2" ; PCF fan
M106 P2 S0
;
M563 P0 S"T0" D0 H1 F2 ; Define tool
G10 P0 X0 Y0 Z0 ; Reset tool axis offsets
G10 P0 R0 S0 ; Reset initial tool active and standby temperatures to 0C

I would now like to set the microstepping and steps/mm for the extruder associated with "Tool 0". What am I doing wrong?

Thanks!

Consider your example for configuring the X axis:

; *** X axis *****
M584 X0 ; custom drive map
M569 P0 S0 ; Drive 0
M574 X1 S1 P"x_stop" ; End stop
M566 X400 ; Set maximum instantaneous speed changes (mm/min)
M203 X35000 ; Set maximum speeds (mm/min)
M201 X6000 ; Set accelerations (mm/s^2)
M208 X-35:328.5 ; Set axis maxima & minima
M92 X100 ; Set steps per mm at default 1/16 microstepping
M350 X16 I1 ; Configure microstepping with interpolation
M906 X1400 I30 ; Set motor currents (mA) and motor idle factor in percent

As an example since M584 must come before M350 how would you configure the Y axis?

With your approach it would start with another M594 which would be after the M350 which according to the docs is not allowed.

You should enter a complete configuration for both X and Y using your approach into a config_test.g file and see what happens when execute M98 P"config_test.g".

We will see if the docs are correct or not. It should be interesting.

OK, now I see what you are saying. I read the documentation to mean that the M584 for a given axis had to come before the M350 for that same axis, not that the gcode needed to have all M584s before all M350s.

I'll give it a try!

GeneRisi

I just created SeqTest.g which contains this:

M584 X0
M350 X16
M584 Y1
M350 Y16

It runs fine. Did it do the right thing? I don't know yet.

So, @dc42 , which is true?

Phaedrux

I think the problem is that M584 isn't empty by default. So when you set a single axis, the other axis are also defined as the defaults. This can lead to some unintended consequences.

There are only a few order dependencies in RRF and M584 is one of them.

GeneRisi

@Phaedrux , I think my situation now could be a cautionary tale. I went to the printer and smelled something acrid burning. The hemera hot end turned on and the cooling fan did not, so it burned and melted.

When I disconnect the hemera, reinsert the sd card with version 2.x on it, I now get an error message after it asks me to do a manual bed leveling, which it never did before. How do I diagnose what's wrong? I am guessing it is hardware unless version 3.2.2 installed something into a non-volatile memory somewhere.

I get this error message now:

SetPositions called when DDA ring not empty

Also, all of my heater settings and temperature reading are -273 ... so strange

Phaedrux

Post your config.g and the results of sending M122.

GeneRisi

@Phaedrux I think I know what this problem is now. When I re-insert the sdcard used for RRF2 after the failure, it didn't automatically install RRF2 firmware back on the board, so of course it doesn't work now.

Since my goal is to get RRF3 working, I will redo the config file to the more standard approach.

Phaedrux

That's correct. The firmware is flashed to the board itself. The SD card is just a storage medium for the config files.

The easiest way to switch between firmware for RRF2 and RRF3 is to upload the full release zip files for the version you want, and then upload your config files for that version.

@Phaedrux Thank you!
