I have a heavily modified Prusa I3 Mk2.5s and am currently running a duet 2 wifi on it. I am extremely familiar with the duet firmware and g-codes however, I've hit a roadblock. The probe only works when the bed is cold since it is the Prusa "pinda". It has a thermister in the probe and I know that the G31 code allows the use of the S T and C parameters but I am unsure how to use them and could not find any documentation. Any help would be appriciated!
Thank you

@Phaedrux the motors are standard nema 17 motors and i am running them at 1000 and they still make a weird noise. and no the belts are tight.

@dc42 that helped, that problem is now solved, thanks.

Perfect, it is fixed. however now when i start a print it said Error: G0/G1: target position not reachable from current position so at the end of home all i told the printer to move down 5 extra mm and that seed to fix that error. But now i am getting some awful grinding, stepper driver noise when starting a print but not when homing. however their is a slight hum noise when motors are engaged. attatched is the gcode--- 20mm_cube.gcode

never mind, that seems to have fixed the thermister issue but now it is heating at a super slow, like 1 min to hit 40c.

@Phaedrux said in Thermister issue using firmware 3.0:

M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1 M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit

Thank you, that fixed it.

I am stetting up my delta printer on firmware 3.0 and to start used the configuration tool but for some reason i can only get my heater temperature to say n/a. What am I doing wrong, the config is below

I am currently using the duet 2wifi and want to use event logging. I read the documentation on it and it does not do exactly what I need. Does anyone know if it is possible to log or graph the temperature fluctuation on a print as well as the printing speeds?

M98 P"homeradius.g"

I checked all of the motors and they are set up correctly, i also have end stops for every motor. The following video shows what happens then i hit home all. This also shows up in the console-

6:14:57 PMError: Bad command: ''' Home Z'''
Error: G0/G1: insufficient axes homed
6:14:57 PMError: Bad command: ''' Home bed'''
6:14:52 PMG28
Error: Bad command: ''' File homeall.g'''

I finally figured it out, the people that I had make the harness had swapped 2 of the pins on the expansion header and was causing the motor not to turn.

Thankyou for your help-
Gregory

I am using stepper controllers off of the boards. "Closed loop steppers" these are being pulled off of the expansion pins. As far as i know, this is needed for my specific situation. Is this correct?

@dc42 said in Using extra axys with a scara kinematic printer:

G1 H2 Uxxx

When I run that command the motor still wont move. The same thing happens when I try to home. Is this a compatibility issue with the Scara kinematics or am i missing something?

After the G91 command, the G1 command still does not do anything,

@dc42 said in Polar Not homing:

M98 P"homeradius.g"

The command M98 P"homeradius.g" shows the following in the console and slowly turns the bed for about 5 seconds. Ignore the motor phase issue I believe it is a loose wire. Sorry for the confusion between my forum posts. this is now in the right thread.

Sorry, I did it on the wrong machine i have a bunch of projects going on right now. I will try it on the scara and send you the correct information this time. The response above was suppose to be for my other forum post.

Hello,
I am currently trying to get a extra axis (U) set Up on a scara machine. I got it working on a Cartesian machine but cant seem to get the scara firmware to home or move the extra axis motor. I am using the new duet 3 board. Here are the config and homing files. homeu.g config.g

@dc42

Thankyou, Gregory

Here are my homing files. homez.g homeradius.g homebed.g homeall.g

I just checked the new homing files, and they seem to be the same and throw the same errors, is it possible that i am missing something?

Thank you, I will try again and let you know

Hello,
I am working on building a polar printer and am having some issues homing.
I get the following Errors when i press home all and assimilate when I tried to home each axis individually.

10:52:13 AMG28 Z
Error: Bad command: ''' File homez.g'''
Error: G0/G1: insufficient axes homed

10:52:11 AMG28 Y

10:50:45 AMG28

I did follow the Guide on setting Up the polar here https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwarePolarPrinter and the home files are the exact same as the ones given. the names are also the same as in the guide.

hrere Is my config.g
