What initial temperature value is displayed (either in DWC or on the PanelDue) for the thermistor you rewired? Disconnect the heater from the Duet. What resistance do you get when you measure the heater at this connector? Verify the cabling of your bed heater. If you don’t get any insight from these steps, double-check the assignment of bed heater, hot end and its thermistor to the Duet ports in your config.g. If all this doesn’t help, please post your config.g.

@chriskimbr said in Dual Drive Extruder clicking. Extruder speed too high?:

;M203 X9000.00 Y9000.00 Z180.00 E1500.00 ; -origional- Set maximum speeds (mm/min)

M201 X3000.00 Y3000.00 Z250.00 E400.00

Your previous acceleration for E was very high. The speed was fine. Now your speed is too low 400mm/min is only 6.6mm/s which would be very slow for retraction.

Your extruder max speed should be as fast as your retraction speed. 6000mm/min for 100mm/s retraction max.

The acceleration for E should be fine in the 2000-4000 range. 12000 is crazy high.

Well it will be the way to go in the near future, but currently if all you want to do is print I would suggest sticking to 2.05.

If you change the pulley diameter you will probably have to move the motor mount to keep the belt parallel to the guide rail.

sorry the endstops info mentioned was for another thread.

Titan with a 1.8 stepper should be in the 400-420 step range and double that if using a 0.9 degree stepper motor with the 16x microstepping. I have a bondtech BMG clone extruder on my ender 3 with a 0.9 degree pancake stepper motor...my esteps after calibration are 846.90. Also your acceleration is very high for your extruder which could also be causing issues. I have the max speed and acceleration for my extruder at 3000.

M92 X80.00 Y80.00 Z400.00 E846.90 ; Set steps per mm (gregs wade was 604 steps)

EDIT: I see you commented out those high speeds...I didn't see the semi-colons at first glance.

@chriskimbr said in Need help! please! Duet2wifi and bltouch ZOffset:

Question: on the duet2wifi if i change the config.g g31 zvalue and save it.
Do i need to reboot device to take effect?

Yes. It will prompt you to restart the board for it to take effect.

If you wanted to configure it on the fly, you could send the command in the console and it would take effect immediately without a restart.

@jrdm fair point! 😄 The docs I linked specified 18A, but I think not all the Duet 2s had fuses and it's the fuse holder that limits ot to 15A.

x16 microstepping with interpolation is usually the ideal way to go, since it's quite and smooth and doesn't pose undue load on the CPU. The exception to this would be the extruder, where it can be best to increase the microstepping to the point where your extruder steps per mm are in the range of 400-800.

@veti said in Extrusion Calibration Bowden throug hotend or Not:

@dc42

does that not introduce to many variables?
like the variance +/- 0.05 of the filament?

No, because you would still measure the filament distance at the extruder drive input.

The R value in the M305 command can be omitted, except by some users of legacy Duets (0.6 and 0.85)

That picture suggests that your manual adjustment of the bed levelling screws didn't work very well. You might like to try this method https://duet3d.dozuki.com/Wiki/Using_the_manual_bed_levelling_assistant.

To get a short from the heater voltage to Vssa there are usually two faults. The first is a short between the thermistor wire and the hot end metalwork, which you have found. The second is a short between a heater wire and the hot end metalwork. So check the heater wires where they come out of the cartridge. If you can't find a short, then there may be a short in the heater cartridge between the element and the case.

Can you give us some more information?

Good question. Im not sure about direct or bowdnen.
Im not really printing anything flexible now.

Titan Aero.

thanks for the info guys and suggestions

@chriskimbr said in BlTouch on Bootup is retracted.:

So i put the m98 Presetprobe.g at the beginging in case there is an error. the resetprobe.g contains M280 P3 S160 I1

May want to add G4 P500 after the command to clear the error to pause for half a second to give the servo time to activate.

Glad it's working now.

I didn't think of that! I'm glad you solved it.

@deckingman found out of desperation when a mod ment I couldn't reach a limit switch! 😄

Edit: Slight error. Think the G92 comments were used in the old reprapltd firmware homing routines. Seem to remember a conversation with dc42 about why I had G92 commands in the homing routines when I dusted it off to build parts for the core xy.
