@SteveYYC adding ;e to the g1-line has answered my question #1. thanks again.

@Danal i do not have a z-endstop mounted near the nozzle - i don't hav a z-endstop at all.

dc42's hint solved my issue.

@SteveYYC

1. inserted m80 into config.g and i did not (yet) observe the absence of the atx control box. having an eye on it.

2. i had 'G1 X0 Y0 Z75 f1000' at the end of my print file. added ';e' and now the correct total number of layers is displayed.

thanks for your help.

@dc42 sorry for my late reply

these are the results of my measurements

1000 ohm -> 160c
33o ohm -> 215c
220 ohm -> 237c

which are roughly consistent with https://e3d-online.dozuki.com/Wiki/Thermistor_table. . so i feel, it's the thermistor which provides too low resistances. consequently there is no reason to blame duet.

thanks for your assistance.

i have a working apache and configured a reverse proxy for dwc. accessing the url results in

"Failed to connect to <proxy-name>" <cr><nl>Network error"

the proxy-access-log says:

the first 4 gets succeed whale all the others fail.

@dc42 going to check tonight.

@pipersw i do not want to discuss this but i feel a reverse proxy is far more flexible.

@pipersw i could but this complicates things.

@spllg had a look at https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/linux-apache?view=aspnetcore-3.1 but microsoft world is very unknown to me. so i think i will give octoprint a try (after i have reconfigured duet3 in standalone mode).

@dc42

• yes, it's a genuine e3d thermistor
• my pla is specified to be printed 190C - 210C but can't be printed below 215C (better 220C)
• i installed a 2nd thermistor (from a cheap chinese hotend which printed reasonable @195C

as i'm kind of losing faith, yesterday i also contacted e3d.

@dc42 said in RepRapFirmware 3.01-RC1 released:

the temperature reading is still ~20C @200C

sorry, i mean "the temperature reading is still ~20C too high @200C"

i'm running with an attached sbc

@dc42

send M308 S1 P"temp1" Y"thermistor" B4725 C0.0000000706

send M308 S1

results in

Sensor 1 type Thermistor using pin temp1, reading 20.3, last error: success, T:100000.0 B:4725.0 C:7.06e-8 R:2200.0 L:0 H:0

the temperature reading is still ~20C @200C

@dc42 connected the thermistor to temp2 - same result.

further info:

M308 S2 P"temp2" Y"thermistor" B4725 C.000001

results in

M308 S2

returning

Sensor 2 type Thermistor using pin temp2, reading 12.8, last error: success, T:100000.0 B:4725.0 C:10.00e-7 R:2200.0 L:0 H:0

the same holds true if the thermistor is connected to temp1.
