@bearer S3D is very picky about its ports. On Linux, it won't accept a "virtual" serial device like you'd create with socat. I can't try Windows but it might be worth a shot.

just occured to me using any esp8266-ish (board be it nodemcu/wemos d1 mini etc) you could probably combine Duet telnet with esplink firmware on the esp8266 to get you a hardware serial port that is networked to the Duet.

(but printing from the duets SD card is one of the bigger features)

((and with RC11 you could also get raw g-code from the PanelDue port to put into another esplink to avoid telnet))

@dc42 said in PID tuning:

Those figures look about right for a V6 with a 40W heater and a silicone sock over the heater block. But a 40W heater is over-powered for that configuration, you should use 25W or 30W. 40W is appropriate when using a copper heater block and no silicone sock, for high temperature operation.

Thank you for the advise and reassurance appreciated as always

@Stevo .....and answers to my questions?

Hey,
I cannot hear any differences between the motors and neither of them are noisy or hot in any way. I will be printing the lid for the box over the weekend and will rotate this on the bed as you suggest by 45 degrees.

This being a snap shot of the third layer being printed which looks fine the rough area to be seen top right the layer in question as being rough.

The box turned out ok in the end two small supports didn't make it as I had decided to try printing without any supports. but it will serve its purpose momentarily.

RRF3 wiki page was correct already. https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_M950_Create_heater_fan_or_GPIO_servo_port

Ian

if it consistent on the macro but the offset is wrong then you need to adjust the offset.

Thanks for the info

@Veti Hey thank you it was the deploy and retract files remaining error message gone!
Much appreciated help as always

Give these a try:

M566 Z120 ; Set maximum instantaneous speed changes (mm/min) (Jerk) M203 Z600 ; Set maximum speeds (mm/min) M201 Z240 ; Set maximum accelerations (mm/s^2)

I have a very heavy and slow Z axis and these are the values I use for print moves. For homing and jogging moves they are a bit lower.

So last ditch attempt have taken the pin out cleaned it put it back and it did its self test several times hooray oh hang on that was short lived.

I am now looking for an alternative to the bl touch thank you for all your help getting me to this point but I must just have the crap one! lol

I don't want to be ploughing the printhead into the bed so its time to move onto something more reliable IR ?

I'm guessing you may be printing outer walls first and have retraction disabled for travels inside the part?

Would need to know much more information to be able to diagnose what's going on.

Thanks again everyone for your continued help much appreciated and will hopefully be confident enough to help others.

Looks good!

@veti Many thanks you hit the ball straight out of the park have slowed the speed down a little and all is well.

Thank you

Thank you all for your help have now got to grips with it much appreciated!

@stevo said in Impulse buy why do I do it !:

Hi all,
I think I may have made a mistake with an impulse buy on 2 motors to run a Z axis on a Corexy printer I have just started building.

I read the the information on buying Nema 23's in the selecting motors section on the site.
I have purchased 2 Nema 23 Bipolar 0.9deg 1.26Nm (178.4oz.in) 2.8A 2.5V 57x57x56mm 4 Wires.

I have taken the 2.8A literal as a max just looking for a yay or nay please.

They sound similar to the 1.8deg Nema 23 motors that I use for testing the Duet WiFi/Ethernet at max current. They will be fine at between 2.0 and 2.4A current. Use 24V power, or keep the speed low.

Many thanks for the reply very much appreciated.

@wyvernThank you for the information much appreciated

I am quite happy with the DWC v2.0.0RC3. You will want at least the DWC v1.22.6 if for no other reason than bug fixes. The Wifi server v1.22 is also good to have, it fixes a bug that the DWC v2.0.0 seems to tickle, though the 1.22.6 probably won't.

Glad you got it sorted!
