Thanks for your reply. I tried another (older) iiyama and that works perfectly…. Go figure. Both have Linux compatibility. The older screen is eol though and it’s not mine.

Good idea to ask iiyama. I’ll do that and see what comes up.

Hi guys, I'm struggling with a touch screen. My setup is a duet 6HC with a raspberry 4B 8Gb and that works. I like to have a large screen on it, hence a 21.5" iiyama prolite touch screen T2252MSC-B1. The good news it that the screen works fine, and the touch also works without having to install or setup anything.

But, the touch is very troublesome. It almost never does what is expected, which would be when I tap the screen behave like a left mouse click. It does move the cursor to the place where I tap, or right button click which opens the right click menu. Only once in 10 times I get the expected left mouse click. Infuriating and basically useless.

I spend hours and hours on raspberry forums to see how to disable right mouse click or otherwise modify behavior. Unfortunately I couldnt find anything useful. I'm very unfamiliar with raspberry/linux so I can only do basic stuff like modify config files.

Of course I can kick out the raspberry and replace it with with a windows PC to enjoy a proper touch screen, but that is a waste of space and money.

If somebody has a good idea how to improve this I would be very grateful!

@fcwilt Dont give the homing command when already homed. Not sure why that is a problem, but apparently it is in my case.

So I need to figure out what homing/tool/temp settings/commands are executed where: config, start, homing, cura. For me its not completely clear yet what makes the most sense.

Anyway the main problem I had is gone: I now have a more or less working pile of parts on my desk. I'm going to build the actual printer first and work from there.

thanks so far!

ah ok... I'm not trying to reinvent the wheel. Its fine if the printer homes when the print starts, however I currently see 2 problems in that case:

First: The printer only homes after the heaters have reached their setpoint. Not a real big issue but I hate unnecessary waiting I will have a 1000mm z-axis so homing takes a while. I guess this can be circumvented but it seems the default situation and I'm not yet comfortable enough with the whole system to alter sequences.

Second: When the printer is already homed, for instance when starting up a second print, it will halt the print and causes the " insufficient axis homed". Of course I could restart the print and it will work but not elegant.

I could do homing in the start.g file, but how can I make it conditional? I found this but seems not conclusive. https://forum.duet3d.com/topic/17083/conditional-homing-and-z-height-fine-adjustment/20

ah ok good point, will do in the future. Below homing file, and snippet of the gcode file.

I found G28 "homing" in the gcode file, deleted that in the and now it prints. Checked cura, and saw cura placed this in the "start G-code".

Since I home on power up using G28 in the config file, I deleted this in the cura "start G-code" and all is well. Thanks for pointing me in the right direction!

Hi guys, I'm a new user of the duet platform. Today I wired everything up. My configuration: standalone duet 3 6HC, 1x tool board directly wired to mainboard, hemera&volcano printhead and corexy setup. Managed to connect everything, connect to LAN, startup DWC, update firmware and setup the basics using the config tool. I can move and home the axis, play with the fan, extruder and heater. Also use cura with plugin to make a gcode file and load that to DWC and start the print. Since the printer is not build yet I have the electronics laid out on the table.

Unfortunately, when start printing within seconds the error "insufficient axis homed" pops up and when checking, indeed the previous homed axis arent anymore.

Help is welcome! (Config under the picture)
