@droftarts Tractus 3d T650P is my printer

A part of the config.g couldn't be copied (2 reputations or something error)

droftarts

@thomasvanderwal Your Tractus is a delta printer, but your config.g is set up for a Cartesian printer? Do you have an old config that worked?

Otherwise, see https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_linear_delta

@droftarts no, a colleque got this printer from a company. He's gone
I am a educator at a technical school.

droftarts

@thomasvanderwal Okay. I think start again with the configuration tool, but this time select "Linear Delta" for Kinematic type. https://configtool.reprapfirmware.org/Configuration#kinematics

Tractus3D have renamed/been taken over by https://nexum3d.com/. You may be able to contact them and get them to send you a standard configuration for your machine. They are a Dutch company based in Amsterdam, i believe.

RepRapFirmware for Duet 2 WiFi/Ethernet version 3.0 running on Duet Ethernet 1.02 or later

Now that you're seeing some progress it may be a good time to update your firmware before you get too far with configuring. 3.0 is quite old now.

If you have access to DWC, you should upload the following zip files one at a time. It will prompt to install the firmware and restart. Then upload the next version, etc.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.5.4/Duet2and3Firmware-3.5.4.zip

The reason for uploading 3.0 again is to ensure all of the required files are present.

I'm getting no response from the company. Can a new firmware work with a duet 2 wifi/ethernet?
I made a homedelta.g and a config.g with RepRapfirmware config tool. I selected delta printer and I think made the right choices with the parameters (sensors). But still homing is going bizar. How can I fix this? My rods are 230mm.
At what starting point do I have to position the nozzle? A message G28 0 0 gets a response that axes are not sufficient.
I put this in my config.g: M665 L230 R165 B100 H315 ; set delta radius, diagonal rod length, printable radius and homed height
Maybe this is wrong or my endstops are at another sensor or so?

@thomasvanderwal we'd need to see your complete config.g and homedelta.g files to help. However, firmware 3.0 is very old now and it would be easier for us to help you if you upgrade to 3.5.4 or 3.6.0-beta.4.

thomasvanderwal

@dc42 I upgraded to 3.5.4. I have adjusted the homedelta.g many times. This was my last.

@Phaedrux It's going towards me. Then up. Finally it get some kind of stuck en going to make a noise like it's wants to go outside the printer

thomasvanderwal

M119 gives the following message: endstops- X not stopped: Y not stopped: Z not stopped, Z probe not stopped

thomasvanderwal

@Phaedrux
The endstops work when they are triggered. But I'm now looking for the z-probe

thomasvanderwal

@dc42 I am getting no where. Which board get I buy that is compatible for my tractus 3d t650P? The Duet 3 ?

Please send M669 and check the response says "Kinematics is Linear delta ...".

It sounds like one of the motors is not moving when homing. It should move all three together, and the three carriages should go up towards the endstops. When you flashed the firmware, did you disconnect the stepper drivers? If so, maybe you reconnected the stepper motors incorrectly. It's important that the X tower motor and endstop plug into the X driver (driver 0, but actually the middle driver on the board), and the same with the Y and Z motor and endstop. Can you post a picture of the Duet and wiring? Please also post the output of M122 again.

Also, I think your M665 parameters are not correct. Usually the rod length (L) is about twice the delta radius (R), otherwise the movement of the effector is severely restricted. Yours are:

M665 L230 R165 B100 H315

See this diagram showing what you need to measure

This doesn't need to be exact, as once everything is working, you can calibrate accurate numbers.

I am getting no where. Which board get I buy that is compatible for my tractus 3d t650P? The Duet 3 ?

I don't think this is a board problem, it's a configuration problem. You would have the same issues if you swapped to another board. Unfortunately there's not much information available about your printer for us to help you, so we will need to recreate the information from what you can tell us.

I did find this pdf manual for the Tractus3D T850/650P, though it's not very helpful in determining the configuration: pro_series.pdf

@droftarts
I heared from someone that I have to downgrade the firmware to <3.
Is it so that duet 2 wifi with a tractus t650P works different with a newer firmware? Codes that response different?

thomasvanderwal

@droftarts
Rod length 230mm, print bed radius is 200mm (the circle with tractus 3d on it).
I see no z-probe. Height of printer is also a mistery. How can I measure that?

No, you don't need to downgrade. Delta printers work just fine with RRF 3. I have one running on a Duet 2 WiFi, on the latest RRF 3.6.0-beta.4 right next to me. Gcodes to run the printer are the same. Some configuration commands have changed.

You said "a collegue got this printer from a company". Was it supplied with no SD card in the Duet? If there was an SD card, what happened to the configuration files that were on the SD card when you first posted in this thread? Did you delete the SD card? Presumably it was working at some point? If you have the original config.g, please post it.

Rod length 230mm, print bed radius is 200mm (the circle with tractus 3d on it).

These are fine for M665 L and B parameter, but you need the R parameter "delta radius" to be accurate, and I don't think 165mm is correct.
With the nozzle in the centre of the bed so the carriages are level, measure the distance between the centre of the magnetic balls that the rods mount to, as below:

Delta 2.jpg

This should measure one side 'A' of the equilateral triangle that defines the carriage positions, and the effector size 'B'. Then use this formula for the circumcircle radius of each, and subtract the effector radius from the printer radius (less carriage offset) to get the delta radius:

(A x √3 / 3 ) - ( B × √3 / 3 )

This should give you a reasonably accurate (+/- a few mm) for the delta radius, for M665 R parameter.

I see no z-probe.

I don't know what the Tractus3D printer uses for a probe. If there's nothing obvious on the toolhead, then most likely it uses a kinematic bed, and the nozzle pushing on the bed breaks a circuit. I think you can remove the bed and look underneath. If so, do that and post a picture. I also think this wire (blue arrow) is incorrect, and may be the probe wire:

Delta 1.jpg

It has been connected to the "optional external 5V input and PSU control" connector. I doubt this machine uses an external 5V PSU, so I'd guess this is for something else. Please trace this wire.

Also, it looks like the nozzle temperature is controlled by a PT100 temperature sensor, connected to a temperature daughterboard (yellow arrow). This part of your config.g will need to change:

; Sensors
...
M308 S1 P"e0temp" Y"thermistor" A"Nozzle" T100000 B4725 C7.06e-8 ; configure sensor #1

See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Temperature_connecting_PT100
Most likely it will need to be

M308 S1 P"spi.cs1" Y"rtd-max31865" ; create sensor number 1 as a PT100 sensor in the first position on the Duet 2 daughterboard connector

The bed temperature sensor is connected next to the bed heater output, so I would guess that that is a thermistor.

Height of printer is also a mistery. How can I measure that?

Once you can home the printer to the endstops (you didn't say if my previous advice helped), you can measure the height by moving the nozzle down until it touches the bed, and see how far that is. But I think you have other problems to solve first.

@droftarts
I thinck I fixed all probblems for homing.

Next "problem" is printing haha. Error: Attempting to extrude with no tool selected.

droftarts

@thomasvanderwal You have a tool defined:

; Tools
M563 P0 D0 H1 F0 ; create tool #0
M568 P0 R0 S0 ; set initial tool #0 active and standby temperatures to 0C

Send T0 to activate it, or click on the 'Tool 0' name in DWC.

However, I advise you to follow the 'Commissioning' guide: https://docs.duet3d.com/en/How_to_guides/Commissioning particularly as the reported temperatures are likely to be a long way out.

It would be good if you could answer some of my questions, or responded to my advice with changes you have made. It will help me help you.
