    • RE: G2/G3 arcs with R parameter traverse the longer of the two arcs

      Fixed! Thank you. Now I have a beautiful cylinder.

    • RE: Do PanelDue move commands respect config settings?

      @phaedrux Thanks Phaedrux. The software versions are not entirely current (3.2.2 for the Duet, I think). Now that I've re-started the PanelDue and also stopped PrusaSlicer from overwriting my maximum rates it is all back under my control!

      (I'm not keen to update the firmwares right now as I'm printing parts for a new printer. Updates once I am done!)

    • RE: Firmware bundle 3.2.2 released

      Worked for me on two printers with Duet 2 Wifi. One was update from 3.1.1 and the other from 3.2. Updated and restarted and both printers appeared on the net.

    • RE: G2/G3 arcs with R parameter traverse the longer of the two arcs

      Your point about defining the centre relative to the ending points is probably exactly why I am getting the fluted cylinders! Thank you. I'll give it a burl with fixed up points.

      (I am indeed using CCW coordinates for the G2 move, but that's just because I was unable to upload all of the examples I tried. They include CCW coordinates for G3 moves.)

    • RE: Remove smooth scroll when linking directly

      @MJLew OK, I found the hidden interface element (see the rant below) that Phaedrux mentioned, but even though it promises when the command key is down to open the link "in a new tab behind the current one" is does no such thing. It just scrolls the current tab to put the selected command at the top.

      When I hold the control key down I can get the popup that Infiniteloop showed (and it works), that is not how I have to use proper links in the browser.

      • <rant> Hidden interface elements seem to be all the rage (even with Apple software) but they are terrible things for core elements of human computer interface. People should not have to hunt around for random hotspots that do surprising things, and people should not have to RTFM to work a web-page!

      @jay_s_uk said in Y axis gains unasked for limits after homing:

      M98 P"config.g"

      Plus and minus 10 million seem to be acceptable and should suffice.

    • RE: Feedback wanted: conditional GCode without indentation
      1. The coding language that I use most of the time (Livecode) uses "end repeat" to end a repeat loop, "end if" to end a conditional et cetera. It is very nice in that it does not depend on indents and it is entirely unambiguous. I commend it as a model to follow.

      2. No. Do not allow mixtures. They will be confusing.

      3. Ideally you would make the delimiting by keyword and do not support indentation. However, I'm guessing that indentation is already in use, and in that case your idea of something like 'noblockindent' would work rather like M82 and M83 (absolute and relative extruder). Perhaps it should have two keywords 'blockindent' and 'blockwords'.

    • RE: Machine forgets that it has been homed

      @Phaedrux Thank you. Yes, that seems like it will be the problem. I wanted the extruder to have zero idle, not the others... I'll change it and my silence will indicate that the problem is fixed! Thank you.

    • RE: Print ABS in vase mode w/o chamber?

      @Norder I also recommend TitanX. It costs more than plain ABS but I need fewer attempts to get good prints. More than worth it to me.

    • RE: Config.g disappeared

      @droftarts Damn. A bug. Bugger!

      There is no config.bak file on the SD, and I do not recall if there ever was. There is one on each of my older Duet 2 wifi boards.

      It is not possible that I uploaded a default config file, as the events were a shut-down during a print pause (due to a nozzle clog) on one day (I switched the power off, and then when I switched the power on the next day the Panel Due welcomed me to my 'new Duet'.

      Here it the M115:

    • Config.g disappeared

      I shut down my printer yesterday and when I restarted it just now it has an almost empty config.g file on the SD that welcomed me to my "new Duet 3" and prompted me to load the configurator web page. The first line of the new config file is "; Default config.g template for DuetPi" but I do not have a Raspberry Pi attached (never have). No trace of the proper config.g file that was on the SD card yesterday even though my custom homing files are still there. Did I do something wrong?

      My machine is a custom-built printer with a rotary spindle and so I cannot really use the configurator web page for setup, but I do have a backup of the proper config.g file on my computer, even if it might not entirely up to date.

    • RE: Remove smooth scroll when linking directly

      @infiniteloop I can't get that popup menu with any click on my Mac using Safari or with the Brave browser. Normally a command-click on a link will open the link in a new tab but it just scrolls rapidly (not fast enough and yet too fast!) to the entry in the existing tab. Opening in new tabs is expected behaviour and is very useful.

    • RE: Remove smooth scroll when linking directly

      @kuon Oh my goodness, yes! I find the scrolling to be awful and have started using the RepRap gcode page (https://reprap.org/wiki/G-code) as a preliminary source because the new Duet docs are so slow to load...

    • Y axis gains unasked for limits after homing

      I'm setting up a newly made printer with a rotating spindle in place of the Y-axis. I need to have no min or max limits on Y so it can spin without end. I have put no Y limits into the config.g file, and immediately after I start the board the Y-axis works as expected, but after homing all axes with homeall.g the y axis now will not go outside 0 and 200 (mm, I suppose, but really degrees of rotation). Re-starting removes the limits until I home again.
      There is no command to put limits onto Y in the homeall.g file. What have I done wrong?
