Tronxy X5ST 500 configure to Duet Wifi 2

PaulJSR

Thank you @DennisHall and @chas2706 I got the Z prove to light up and seems to be connected properly! Unfortunately my dynamic test is failed. When I put a flat surface under the probe it lit up but the z axis did not stop moving. I used the Z probe config codes you sent. Any ideas what could be going wrong here? Thanks again.

Paul, your homez.g should look something like this:
; homez.g
; called to home the Z axis
;
; generated by RepRapFirmware Configuration Tool v2 on Sat Nov 10 2018 14:56:37 GMT+0000 (GMT Standard Time)
; Use the probe offset

G91 ; relative positioning
G1 S2 Z5 F100 ; lift Z relative to current position
G90 ; back to absolute positioning
G1 X160 Y160 F4000 ; Go to centre of bed

; Probe
M558 A1 F350 ; Set single probing at faster feed rate
G30 ; Do a single probe to home our Z axis
M558 A10 F100 ; Set triple probing at slower feed rate
G30 ; Probe again to get a more accurate position and set Z to trigger height

The G30 command above is using the probe to home Z. You need to adjust your homeall.g as well by replacing the section where Z is homed with the above gcode.

@pauljsr In my gocde above, the : M558 P5 I1 H1 F100 T36000 line is the controlling line for the Z-Probe.

With this setting and when the red light on (i.e. holding metal under the probe), open your GCode console and enter M119
It should read Z Endstop TRIGGERED when your red light is on.
If it does not read TRIGGER for your Z Endstop when that light is red, then your probe is either scrap or you have your brown and blue wires reversed.

It is (knowing TronXY) possible the brown, blue and black wires are not integrated in their problem correctly as well.
Do not be affraid to connect the wires to the FAN0 points and the far left Z-Probe point beside the LCD 4 wire connector. You will not blow up the Z-Probe, but BE SURE to have the Duet powered off when making wire changes around.

Paul, I had the same inductive sensor fitted on my tronxy X5S but now replaced it with dc42's ir probe.
To get your tronxy probe to work you need your M558 command in config.g as dennis pointed out above and your homez.g and homeall.g set up to home with a probe.
You also need to connect the probe as follows:
blue wire connected to 0V
brown to 12V - I used a spare always on fan connector.
black wire connects to the probe input connector which is the leftmost pin next to the 4 pin paneldue connector.
after this all should be good.

Thanks again @chas2706 and @DennisHall
I got that all configured and got some printing going but the filament keeps getting jammed. The extruder spins but filament gets stuck after a few layers. Other than cleaning out the nozzle, how can I prevent this? Lower temperature or turn fans up? Best, Paul

@pauljsr said in Tronxy X5ST 500 configure to Duet Wifi 2:

M305 P0 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 0
M305 P1 T100000 B4138 R4700 ; Set thermistor + ADC parameters for heater 1

These are very likely wrong for your printer.
From a config i found for marlin
Bed: 1 : 100k thermistor - best choice for EPCOS 100k (4.7k pullup)
Hotend: 11 : 100k beta 3950 1% thermistor (4.7k pullup)

The problem with 11 is they vary by a wide margin.
so you are prob printing at the wrong temperature.
see this thread about a discussion for calculation of the correct values: https://forum.duet3d.com/topic/9464/m305-thermistor-values-for-the-duet-maestro-on-the-ender-3-pro/2

@PaulJSR
I take it that your printer has the original Bowden set up and from your first post I am guessing that you have never had it running.
Where I am coming from is that I have a Tronxy X5S that had a Bowden set up and I couldn't for the life of me get the dammed extruder working long enough to do a print without clogging up. I blamed it on the ridiculously long length of Bowden tube that is required.
I converted mine to direct drive and have never looked back.

DennisHall

@pauljsr I agree with @Veti .
Sounds like your tempurature is too high or to low for the type of filament you're using.
I also understand the response from @chas2706 , but in your case, it seems pretty consistent "gets stuck after a few layers" which tells me there is a cool-down happening in your hotend. A few layers, based on a similar print size, would have this effect.

PaulJSR

Thank you @chas2706 @DennisHall @Veti I apologize for the delay I have been out of town. I just ordered new tubes since I can't even unclog the the one that I have. I am told this is called heat creep and assume this is due to my temperature and fan settings being wrong. I will try to adjust the config and if that doesn't work possibly get a direct extruder. Any hot end and fan config suggestions are appreciated. Thanks!

@PaulJSR My X5S came fitted with the same extruder as your X5ST. If you look closely at the nozzle cooling fan you can see that it is a bad design because the fan also blows onto the hotend!

If you decide to go with a direct extruder I have this:

https://www.amazon.co.uk/gp/product/B07C24V3FL/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1

It is a chinese clone but works well as long as you throw away the stepper motor that comes with it because it is way under-powered for the job. The design is extremely light for a direct extruder set up and less than a quarter of the price of the genuine equivalent.

You would also need to print an extruder mount and fan parts from thingiverse:
Extruder mount:

The cooling fan parts are contained in a link in the above mount.

P.S the titan clone can be used as both a direct extruder system or a bowden one. Everything is supplied for both configs.
