@peirof forget it.... Google has the power...

Yes, it's very good for duet. Although, it does not take into account pressure advance, and any slowdowns that could be incurred because of it.

@fcwilt said in Question about setting the Z=0 datum:

Thanks. That was very interesting.

It seems to be well thought out and well made.

Are you a machinist by trade?

Unless you count 2 years in a machine shop as part of my apprenticeship from 1969 to 1971, then no. 🙂

Did you consider using some sort of optical sensor for detecting the hotend movement?

No. Because I had to make a physical stop for the hot end, then it was easier to make that physical stop also be the electrical switch. That way, there are no issues with alignment, offsets, hysteresis or anything else. Two metal plates either being in contact or not, makes arguably the simplest and most reliable switch known to mankind. 🙂 As soon as the bed start to lift the hot end, that is truly Z=0. I just have to always heat the hot end to around 140 deg C to soften any plastic which may have oozed because that would otherwise give a false zero.

@dc42 Thank you. The issue was in the pin to be inverted. I used "!exp.heater5" and not it's working again.

As always you are top starts in supporting the community.

@schild0r said in Thermostatic controlled fan coming on at 50%:

Turns out that the config tool assigns both the hotend fan and the part cooling fan to the tool ...

It should only do that of you tell it to. If you think it is assigning the hot end fan to the tool without you telling it to, then please post a screen shot of the relevant pages of the config tool, and also the generated config.g file.

Thanks @oliof and @droftarts, I'll look into this SBC

@dc42 Much appreciated!

@peirof Use M207 to set firmware retract parameters. Then set the slicer to use G10/G11 in the Gcode (M103/M101 if it's Simplify3D). Then you can change M207 on the fly, during printing. Also try changing speed and acceleration of extruder moves, if tuning.

@droftarts Here it is:

CRC3.JPG

It's this bad when uploading but when downloading it's fine.

@peirof sites your slicer generate periodic gcode with progress estimations? Iirc, if enabled they are shown in DWC

@peirof you can use Arc welder to convert into G2/G3 and there is a plugin for cura for this

@dc42 thx

Thanks @dc42, I can live with 10 secs. This is to update the neopixel color and I can force additional updates on events such as starting a print.

BTW, may be useful to update the documentation, including with the loop idea.

@romanvin it's only when using recent versions of the integrated PanelDue in combination with Duet 3 Mini boards that the Card Detect pin is supported. For this combination, it would be possible to mount the card automatically as you suggest. However, in most cases you will be accessing the card via DWC or PanelDue, which will mount the card automatically when you switch to it.

@rockydubb You could use stall detection to do a emergency shutdown?

@arnold_r_clark Thanks for the feedback. I can't do much about the colour, as that is a site-specific thing. I have boldened the first few Gcodes (G0 to G4), though; does that make them stand out more?

Ian

Thanks. Will do so.

@cornishmad you may find these links useful, although I cannot voice for the accuracy of the information, and I am not familiar with the differences between the various Da Vinci models:

@jayarmstrong you could try the DuetWiFiServer-duet.bin version from here https://github.com/gloomyandy/DuetWiFiSocketServer/releases/tag/V1.26-01
this is built using a newer SDK than the one used by the duet releases
