@jacotheron said in Duet 2 - Version Differences:

Also something useful on the Documentation where the changes are listed (https://duet3d.dozuki.com/Wiki/Hardware_Overview#Section_v1_Num_04), I understand that a probe and endstops could return higher voltages than only 3.3V (without damaging the board). This can be very useful when using something like a inductive probe that returns 5V (or some even slightly higher) without the need to construct an external voltage divider (though this is quite simple, but not plug and play).

Am I understanding this correct, or should one simply avoid probes and endstops that return more than 3.3V?

You are correct. In practice the older Duets will tolerate more than 3.3V on the endstop and Z probe inputs too; but we are unable to guarantee this because Microchip doesn't specify a current rating for the ESD protection diodes in the microcontroller. In 1.04 we added external Schottky diodes so that we can guarantee it.

The printer homes all axis, rather slow ...........................

That's the "F" (feedrate) parameter in the G1 moves for your homing files. I'd leave the slow second pass at 360 but if you want to speed things up, you could try changing the F1800 (30mm/sec) values to 3600 (60mmm/sec) or 4800 (80mm/sec) or even more if you feel it's still too slow and if the machine will take it. You have it set to 6000 (100mm/sec) for the XY move in the home Z but 1800 in the home X and home Y.

Thanks @projectR3D

@gtj0 said in M106/7 P parameter & tool changes:

You can use M563 to associate fans to tools:
https://duet3d.dozuki.com/Wiki/Gcode#Section_M563_Define_or_remove_a_tool

If you use the "F" parameter to set the physical fan for the tool, then that will be the default fan when that tool is selected.

That's the answer, I think.

Thanks for the replies, folks.

@dc42 said in GCodes for the next-generation Duet:

I don't see any need to change how tools and mixing ratios are defined. It's things that relate directly to I/O pins that need to change.

Ahh OK. Light is beginning to dawn.......
BTW I like what you are planning to do with temperature sensors being independent of heaters.

For some reason the Duet was unable to read the file www/reprap.htm. This could mean that the SD card failed to mount - but then it wouldn't have executed config.g, so it wouldn't have processed the M552 S1 command to connect to your router.

I suggest you consider the possibility that your SD card may be on the way out, so back up all the files on it and have another SD card ready.

In practice it doesn't matter whether the trace is cut or not, because the Duet normally tolerates receiving 5V into the STP pin of an endstop input. However, it is only on the 1.04 boards that we can guarantee that 5V won't damage the board.

@dougal1957 oh interesting I see. Thank you.

@dc42 said in Invert logic output H3:

Yes,work.Thanks.

I'm glad you sorted it. The MAC addresses normally used by the Duet have the "Locally administered" bit set, because they are not assigned by a manufacturer of Ethernet chips. Perhaps this is what your router was objecting to.

@v0i9viper said in duet 0.85 no network unless I change the MAC Address:

I still get a 4mm z offset from somwhere when running mesh compensation. all probee values are 4.XX instead of 0.xx. weird.

What type of Z probe are you using; and how do you home the Z axis?

@infamous_panda
I dont care about speed 😉
My next mods are Plexi Cover, 0.9 degree steppers, smart effector with mag balls, linear rails and a flexi drive direct Extruder.
I allready have the parts, but it takes time...

i dont have multimeter but i will consider your suggestion and buy 30w of cartridge to be in safe area. i use silicone sock

What is means is that the master list at https://reprap.org/wiki/G-code lists two meanings for each of those codes, and RepRapFirmware doesn't implement the second one.

I remember also doing this, had some weird items (numbers 1-5) in the GCodes list after some upgrade.
I deleted them and everything was fine.

@sigxcpu great! that worked, it is easy to forget

That's correct, the D parameters in M563 commands are not driver numbers, they are extruder numbers. Your M584 command defines two extruders on drivers 7 and 8, and those extruders will be numbered 0 and 1 for the purposes of the M563 command.

My preference is to have it only pop up if I press the up arrow - then I could see the historical entries, and hit enter in order to select one. This is basically how Pronterface/Printrun worked and was extremely helpful for me (but it didn't have a popup window - it just autofilled one entry backwards with each arrow press).

We build custom units along with our production corexy units. Depending on the build platform you are looking for, we can easily hit a $2000 price point.

If you let us know the build size and features you would like, we can throw together a design for approval.
