Firmware 1.20 released

Both of my Duets stopped printing any G-code file with brackets in it's name after 1.20 update. The files upload fine,it's just that the subsequent M32 command fails with "Gcode file not found". Same files worked fine in 1.19 and before, so it's probably something that was changed with 1.20.

Edit: Rechecked, it's definitely the firmware - already uploaded file prints on 1.19.2, gives error with 1.20 or later. Web interface version had no effect on the outcome.

It's because standard GCode uses brackets to enclose comments, therefore anything enclosed in brackets is stripped out. Workaround is to use double quotes around the filename in the GCode command. The beta PanelDue firmware already does this, and DWC will do so soon.

so, upgraded to 1.2 with help from here (thanks a bunch! :). ) everything seemed fine, but now getting an "error G28 failed to home" with X and Y end stops. Z seems to work fine. thing is it visually/mechanically seems to be homing fine. Setup on a CoreXY. here is a video if it helps figure what I'm doing wrong. what settings and such should I be looking at/for? Supposedly it was a beta version of the firmware issue and was fixed? but I never used a beta version.. just upgraded from 1.18 to 1.2

Is is definitely moving as far as the X and Y homing switches when you try to home all, or when you try to home just X or just Y? The movement in your video looks very short.

Please share your config.g and homing files.

I haven't tried to home all as the Y end stop isn't mounted yet so I trip it by hand myself. reason I didn't show it. I saw the write up on the "home all" for CoreXY which is easy enough .. Short movements was just because I didn't want to waste peoples time watching it slide across, so I was just starting them rather close. - Config -g -

Something very strange going on here. How did you get the situation where Z was homed but X and Y were not? The reason I ask is that you can't home Z unless X and Y have already been homed. At least that's how it is and how it has always been on my CoreXY.

Edit. I think I know why. You have M84 at the end of all you homing files. This cuts the power to the motors and resets the state to be not homed (because without idle hold, they could easily be moved). Take out those M84 commands.

ummm not a clue.. just hit the home Z.. there shouldn't be any reason you can't home Z pretty much any time you want… at least none I can think of.

Odd. Perhaps it depends on what type of Z homing switch you have configured. I use the nozzle to probe the bed so my Z homing files move the head to the centre of the bed. Maybe that;s why DWC won't let me home Z without first having homed X and Y.

Anyway, it's you M84 commands that are resetting all the homing status (including Z because it cuts power to all motors). So take them out.

Good catch! He doesn't have M84 at the end of homez.g, which is why Z is remaining homed.

The motor currents are reduced to the idle value after 30 seconds of printer inactivity. By default this is 30% of normal, which on most non-delta printers is sufficient to hold position. Whereas M84 cuts the current completely, so the motors are flagged as not homed because it is quite likely that they will not be in the same position when you apply power again.

Sweet!! man you guys are awesome!!! I'll check it out in a bit!! Thanks.

That worked!!!!!! thanks a bunch again guys!!! (printing up a few more mounts/parts today on the old i3 clone, hoping tomorrow to be doing test cube prints on this Core XY at the latest )
