Firmware 2.02 released!

[mveinot]

Hi all, been using Duet3D for my CoreXY since the middle of last year or so.

Since 2.02 I've been unable to home the axes correctly. I use stepper resistance to home the X/Y and a BLTouch to home Z (I assume this is probably still working)

After updating to 2.02 I got a message when I try to home about insufficient axes being homed - did some reading and saw I needed to add M564 H0 to allow movement before the axes were homed, so I did that, but now the print head just smashes into the 0 position and tries to keep going instead of determining that's the home position and proceeding with the rest of the home position.

I've placed my config and home gcode files at this location.

Any help would be greatly appreciated.

[wilriker]

@mveinot First of all I would not recommend the use of M564 H0. This opens up a possibility for bad things IMHO. You should always adapt your homing macros as a better solution (and home before any movement).

I was looking at your homex.g (and homey.g) and at least they should not create this error message. Maybe your homeall.g does. Only thing that I found a little strange in your homex.g is that you go to home, go to X=5 and at the end set this position to be 0 via G92 X0. This might be totally correct for your setup but I find it quite strange. (I also find you regular acceleration values of 15,000mm/s² strange but again this might be totally fine for your machine)

Anyway, regarding the stallGuard-based homing I sadly cannot really help since I don't use it. The only thing I can think of is that something changed (mechanically, inside firmware) and your previous stallGuard settings just don't work anymore, i.e. it does not detect the stall.

[mveinot]

@wilriker Thanks for the insights. The reason I set the x=5 offset is that the x/y carriage bumps into part of the printer frame if I don't move it in a bit on that axis.

Even trying to home each axis individually I was still getting that error (insufficient axes homed)

My homeall.g just calls each of the individual homing files in sequence, it doesn't do anything special.

[wilriker]

@mveinot Oh wait, you have M452 in your config.g. This sets your printer into Laser mode. In this case it is mandatory to change all your G1 Snnn into G1 Hnnn. This is because in 2.02 when the printer is set to laser mode the Snnn parameter of G1 controls the laser power!

From the documentation of M452

Very important! If you use M452 to put your machine into Laser mode and are running Firmware 2.02 or above, you must replace all S parameters in G0/G1 commands in homing files etc. by H parameters. This is because S is now used to control laser power.

[mveinot]

@wilriker Darnit! I forgot all about having that in there. Yep, that did it. Thank you so much.

[dc42]

@mveinot, you can avoid the move to X5 and G92 X0 if you change the M208 lower X limit from 0 to -5.

[mveinot]

@dc42 Thanks, I've made that change as well. Seems to work!

[Hornetrider]

Hi Guys,

I hope you can help me out.
I have updated to latest FW2.02 and DWC2.0.0-RC3 and at first it looked great.
But since the update I can't home my axes, any of it. I tried to modify the home files, f.e. homex.g with very slow movement but that didn't help.

I allways receive the error G0/G1:insufficient axes homed

I checked the switch states again and they work fine.

It seems like S1 is ignored...

[Phaedrux]

@hornetrider Can you post your other homing files? Homex looks correct.

[Hornetrider]

@Phaedrux

thanks for the quick reply.
The homeall.g looks similar to the homex.g as it was generated with the RepRapFirmware Config Tool.
It uses the same controls just for all axes and including the G30 for the Z Probing.

The strange thing is, before the FW update (done 02.01.19) the homing worked fine...

Also
G1 S1 X-215 F1800
G1 X6 F6000 ; go back a few mm
work fine as the X-Axe goes back the distance after hitting the first time the switch....

But at the end of the script the error message appears.

Tried also to replace the Sx by Hx and it didn't help other than generating an error message less precise then the G0/G1

This is kind of anyoing.

BTW
in the SYS Folder, what files should be there.
After Update I have far more there...

[wilriker]

@hornetrider Your homeall.g looks OK to me. Though I don't use G30 in my setup so not sure if there is anything needed to adjust.

Regarding the amount of files in /sys: the new simplified update with just on ZIP file contains all the various update files for Duet Wifi, Ethernet and Maestro. This will add some files to your /sys folder that you don't need but they don't do any harm either.

[Hornetrider]

@wilriker

thx.
Did you have a Cartesian Style Printer?
Have you had to change any commands after update?

I am going crazy...and most likely it is something tiny...like allways...arghhh

[wilriker]

@hornetrider Yes, I do have a Cartesian printer and since I follow along all Beta/RC versions and usually immediately adapt to all introduced changes I did not have to adjust anything special here.

Here's my homeall.g for comparison:

@wilriker
HI Manuel
just used your setup and it didn't work....

It seems to stop right after x/y hit the first time the limit switch...

[dc42]

I think the problem may be the I0 in M906 and the S0 in M84. My guess is that this sets the motor currents to zero immediately after the homing move stops, and that is flagging the axes as not homed again.

[Hornetrider]

@dc42
You are a genius!
After setting I0 in M906 to I0.1 it works fine again!

Thank you very much!

[BPisLife]

@dc42 thanks for incorporating my feedback on the latest PanelDue firmware with both the Stop button taking priority and actually stopping the printer immediately as well as the 2mm/s federate on the extruder.

Really liking the notification system on the latest firmware! Nice work to everyone involved.

[joestefano]

David, I am having trouble with Z height reliability. I am using your Z IR probe, I have a slightly tinted glass heat bed approx. 6mm thick. I have placed a piece of black paper under the glass at my home location. I test it by homing the printer then entering G1 Z0 and most of the time the Z gap is tight against the glass (to tight to print first layer). I repeat the procedure with G92 Z0 after adjusting the Z gap then runG30 S-1 and enter value in M558. Is there anything I can do to improve this.

I am running 2.02

; Endstops
M574 X1 S0 ; Define active low and unused microswitches
M574 Y2 S0
;M574 Z1 S1
M564 H0
M558 P1 X0 Y0 Z1.297 H0 F500 T3000 ; Set Z probe type to modulated, the axes for which it is used and the probe + travel speeds
G31 P500 X0 Y0 Z 1.1 ; Set Z probe trigger value, offset and trigger height

[dc42]

G1 Z0 should place the nozzle just touching the glass if you have set the trigger height correctly in the G31 command. The printer will command the nozzle to the first layer height before it prints the first layer, for example it will send G1 Z0.2 if your first layer height is 0.2mm.

If you are using a config-override.g file, check that the trigger height isn't being overwritten by another G31 command in that file.
