@jml the previous two replies have got it right between them. IN RRF 3.5 the machine position in the object model is updated every 200ms during moves.

@T3P3Tony No worries, I figured! But I will keep my fingers crossed 🤞

@jml nevermind - I had to sign in in order for github to show Code results. Thanks!
(is there a way to mark this post solved?)

Take a look here: https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m573-report-heater-pwm

And you can set the frequency in the M950 that defines the heater.

Take a close look at the other chips and see if you can spot and scorched. Sounds kind of like a short took something out.

Anyway, I've tried the new 2019 q4 major update, and it is not improving the results at all. Still lots of the same error like undefined reference to `pow'. Hmmmm

@jml said in I2C pullup resistance change:

I use a logic level converter to convert the I2C to 5V for a peripheral device. Do you think I should also use 1kohm pullups for the 5V side?

i haven't usually needed that for other projects, but no idea what level translator you are using, or what slave devices. but if sda is driven low it would suggest the level converter or the slave is doing it.

another pull-up on the 5v side shouldn't hurt as long as both slave and master can still pull it low.

@Danal Yeah its not a big deal because not using that often.

I agree it would add additional customization.

FTP is a much quicker way to do it over the network, but you can right click and download files and multiple selections of files.

@jml It almost certainly does not conform looking at the list. Also it is generally not a good idea to put it on an open network (where you do not control the access) like the internet or a school network. I would use access point mode:

https://duet3d.dozuki.com/Wiki/Gcode#Section_M589_Configure_access_point_parameters

and have it on its own network.

Interesting

Yes any thermistor pin should work, however they all have an RC filter between them and the processor, so you can't use them to measure rapid changes in voltage. To see whether there are any other expansion pins you could use, see https://duet3d.dozuki.com/Wiki/Duet_2_Pinout_table and the datasheet for the ATSAM4E8E-AU chip.

Perfect, thank you.

Found the schematics. The answer is: the 3.3V pullups are on the duex5 and not on the duet, so I gots to add my own pullups.

@stephen6309 ah makes sense now!

@jml said in PanelDue (7i) button accidental button presses:

@dc42 Ok, so if I'm occasionally getting presses registered in places where I am not actually clicking then I guess that means either my mount is pressing against a touch-sensitive part of the screen a little bit, or the touch-sensitive part of the screen is faulty.

Yes. In a high humidity environment, condensation on the connections to the touch membrane might also cause that problem.

Yeah unsynchronized is required because I just want it to keep spinning at a constant speed without slowing down when other axes are accelerating/decelerating.

Maybe I can just make two setups. One with a stepper for synchronized. One with a dc motor for unsynchronized.

Or maybe I can have one setup that has a stepper motor, an arduino, and a stepper driver, and a switch. The switch electrically disconnects the motor wires from the duet's motor driver. And it connects the motor to a different motor driver controlled by the arduino.

oh yeah!
